PREF ACE Believing with Bacon, that, "It ought to be eternally resolved and settled, that the un- derstanding cannot decide otherwise, than by Induction, and by a legitimate form of it," I have endeavoured in the following dis- course, to do something towards settling the great problem. The discourse therefore, lies within the province of logic in the most com- prehensive meaning of that term, as embrac- ing the method of investigation, the grounds of human belief, and the origin of all knowl- edge. It is true, that in the first part of the discourse, I have endeavoured, not only to show the grand results of Induction as an or- gan of Investigation, but also, to vindicate the philosophy which it has built up from the grave accusations that have been preferred against it. But this is nothing more, than a vindication of Induction from objections urged against it, on account of the imputed conse- PREFACE. quences to which it leads. The discourse therefore, in all its parts, lies strictly within the province of logic. The whole empire of human thought has been traversed in the discourse, revelation as well as nature has been searched, and induc- tion has been found every where, the true method of Investigation. And so far from its being the Organon of Infidelity and Atheism, as has often been asserted, it is found, that all the lines of investigation which it lays open, whether in physics or psycholo- gy, ultimately converge and point upwards, to an inquiry that results by the strictest log- ical necessity in the belief of a God. And when the province of revelation is entered, it is found, that the very truths which Induc- tion has discovered in the province of nature, are assumed as true, in its teachings; and. that nothing is told in revelation which does not consist with the inferences which Induc- tion has established in the province of nature. And on the other hand, whenever man has cast aside Induction, and let go the thread of experience as an inadequate c)ne. to the lab- TREFACE. arynths of knowledge, aad attempted by an a priori method of investigation and its cor- responding doctrine of fore-knowledge, to ascertain the truths whether of nature or rev- elation, we find that nothing but ever-vary- ing and ever-increasing error has been the re- sult. It would seem therefore, to be a legit- imate conclusion ; " that the understanding cannot decide otherwise than by Induction." In undertaking a task so foreign to my ha- bitual pursuits, I have been influenced by a love of truth, and a strong desire to vindicate a Method of Investigation, which by its great doctrine, that experience is the only light to our path, and lamp to our feet in the pursuit of knowledge, is pushing forward the front- iers of science in every possible direction, with such triumphant success. And when I reflect, how far the task was beyond my abil- ities, I rejoice to know, that all the errors which I may have committed in the execu- tion of it, will be corrected in the progress of truth.

PART THE FIRST The Influence of the Baconian Phi- losophy. — Some one nation always at the head of the rest. England at the head of modern civilization. In modern civilization there have been three great revolutions : the religious, the philosophical and the political. The philosophical revolution originated in England. Lord Bacon stands at the head of this movement. The object of this revolu- tion. Bacon's writings their publication and their circulation. Royal Society of Lon- don. The leading discoveries of the physi- cal sciences made in England. These dis- coveries enumerated, and the method of their discovery pointed out. These discov- eries objects of the most delightful contem- plation. Contrast between -the physical dis- 10 TABLE OF CONTENTS coveries of the ancients and the moderns as objects of intellectual contemplation. Baco- nian philosophy practical. The application of its discoveries to the mechanic arts. The benefits conferred on England by the Baco- nian Philosophy. This philosophy not con- fined to physical nature ; but embraces intel- lectual and moral science. The opinion that this philosophy leads to a mean standard of beauty, refuted ; and the question examined at large both by philosophical analysis and historical fact. English literature examined, and its distinguishing features pointed out. The opinion that the Baconian philosophy leads to materialism and atheism refuted. The Baconian philosophy likely to form the type of universal civilization. PART THE SECOND.— CHAPTER I. The Baconian Method of Investiga- tion. — The Aristotelian logic. The reason- ing process in its form, is the syllogism. All reasoning proceeds by comparison. The fundamental principle of the syllogism. Ba- con did not design to teach a new mode of TABLE OF CONTENTS. 11 reasoning, but a new mode of investigation. The a priori method of investigation nothing more than a misapplication of the Aristoteli- an logic. The influence of the a priori meth- od of investigation upon philosophy. Bacon appears. His instauration of the sciences. The Novum Organon, its object, the spirit of its philosophy, and the nature of its method of investigation. This method called Induc- tion. It is the reverse of the syllogism. Analysis and synthesis considered, and both shown to be inductive processes. The appli- cation of mathematics to the inductive scien- ces considered. Induction carried on by principles of evidence and not by principles of logic. The nature of analogy considered. The inductive process founded on analogy. The great fundamental principle of philo- sophical evidence developed ; and it is shown to bear the same relation to induction that the fundamental principle of logic does to the syllogism. Whether Bacon discovered the inductive process considered. PART THE SECOND.— CHAPTER II. The Theory of Mind assumed in the 12 TABLE OF CONTENTS. Baconian method of Investigation : — Only two theories of mind, the theory of innate ideas, and the theory, that all our knowledge is founded ultimately upon expe- rience. The theory of innate ideas, is the theory of mind assumed in the a priori meth- od of investigation ; and the theory, that all our knowledge is founded upon experience, is that assumed in the Baconian method of investigation. Plato the leading Philosopher amongst the ancients, and Des Cartes amongst the moderns, who maintained the theory of innate ideas. Both these Philosophers main- tained the a priori method of investigation. Bacon's theory of mind, the same with that of Locke and Reid. They all maintained the theory that all our knowledge is founded upon experience. Locke solved the funda- mental problem of psychology ; and Reid de- veloped the fundamental laws of thought. The Baconian method of investigation the psychological correlative of the theory of mind that all our knowledge is founded ulti- timately upon experience. The theory of mind taught in the sacred scriptures. The TABLE OP CONTENTS. 13 philosophy of Kant examined. The Bacon- ian method of investigation traced up to the first impressions made upon the senses. PART THE THIRD. Natural Theology: its place amongst the Sciences, and the nature of its evidence : — Natural Theology a branch of the inductive or Baconian philosophy. The errors of Lord Brougham's discourse of Na- tural Theology pointed out. The place of Natural Theology amongst the sciences and the nature of its evidence pointed out by Bacon. Hume's essay on a special Providence and a future state considered. The error of the essay shown to consist in confounding a mere physical cause with an intelligent creator. This error shown to lie at the foundation of all atheistical arguments. The evidences of Natural Theology traced up to the idea of causation developed in consciousness. PART THE FOURTH. The connection between Philosophy and Revelation: In the interpretation of 14 TABLE OF CONTENTS scripture^ revelation must not be subordinated to philosophy. The subordinating revelation to philosophy is now^ and has always been the chief source of theological error. The influence of various systems of philosophy on Christianity examined. The Baconian Philosophy the only one consistent with Chris- tianity. ANALYTICAL INTRODUCTION. The Baconian Philosophy is emphatically the philosophy of protestantism. Luther de- nounced the Aristotelian logic, because it was the foundation of the scholastic theology, the frame-work which supported its superstruc- ture^ and the cement which held together all its parts. And Bacon denounced it, because it was the foundation, and frame-work and cement of the a priori philosophy. Protes- tant Christianity and the Baconian philosophy originate in the same fountain, and flow to- gether in the same channels. And it is very remarkable that just now, so much attention is directed to the two great revolutions of modern times — the religious revolution ef- fected by Luther, and the philosophical revo- lution effected by Bacon. Two more elabo- rate histories of the reformation than any ev- er submitted to the world, are now being ;16 ANALYTICAL INTRODUCTION. written, and are nearly completed,— the one 5 by D'Aubigne in Switzerland, and the other, by Ranke in Germany. The first, as far as completed, has been translated into English, and published and read with the deepest in- terest over all Great Britain, and has been republished and read more extensively, in this country, than almost any other book. And from the high reputation of Ranke, and the absorbing interest of the subject, his his- tory will doubtless soon be translated into english and circulated through all the multi- plied channels of publication. And the most animating interest in the great theme, will be kept alive. And within a few years, Mont- agu's edition of Bacon's complete works, with translations of those written in latin, which had engaged the attention of the edit- or more than twenty years, has been publish- ed in England, and is now republished in this country ; and the popular publications of England, and the great periodicals of both that and this country, have been for a long time teeming with commentaries and exposi- tions of the Baconian philosophy. The ANALYTICAL INTRODUCTION. T? mighty spirit of modern civilization appears to be stirring up society anew, by rehearsing the history of its triumphs, and proclaiming again to the world, its great doctrines. It seems to be gathering up its strength, for a new onward movement. Impelled, by the same influence which is operating upon so many minds in the differ- ent nations of Christendom, we have endea- vored in this discourse, to exhibit a popular and succint, but yet a more thoroughly de- veloped exposition of the Baconian philoso- phy than any which has appeared. In the first part of this discourse, we have set forth, as the leading truth, that the Bacon- ian philosophy has for its primary object, the investigation of the laws of the material world, and the application of these laws, through the instrumentality of the useful arts, to the physical well-being of man. That this philosophy does not think it beneath its dig- nity, to solve the homely problems : "What shall we eat, and what shall we drink, and and wherewithall shall we be clothed ?" But admitting, that philosophers like other peo- 2* 18 ANALYTICAL INTRODUCTION. pie, must feed their hunger and clothe their nakedness, it teaches how to make with more facility and in greater abundance, the food and raiment necessary for our bodies, and proclaims not in whispers, but in its very loudest accents, that Franklin did not more fully exemplify the true spirit of philosophy when he brought down fire from heaven, than Fulton did, when he yoked it to the car of commerce. And as England originated the great phi- losophical movement of which we are speak- ing, and stands at the head of modern civili- zation, we have cited the chief discoveries in the sciences made by the Anglo-Saxon race, and then showed how these discoveries, by their application to the useful arts, have ex- tended the dominion of man over the empire of nature, and in this way conferred on Eng- land so much wealth and power. After thus showing the connection of the Baconian philosophy with the useful arts, and how much it has through them, contributed to the physical comforts of man, we next show that this philosophy does not lead to a ANALYTICAL INTRODUCTION. 19 selfish morality, as some have alleged; but that in all its principles, and in all its aims, it tends to produce a noble and disinterested morality. The next question discussed, is the bearing of this philosophy upon the arts of beauty ; and it is shown by an analysis of its! fundamental principles, that it maintains a, most exalted ideal. And this fact is further proved and illustrated, by spreading out in microscopic view, the literature of England with all its rich and various and masculine beauties, which has grown up under the in- fluence of the spirit of this philosophy. We next defend this philosophy from the charge of materialism and atheism with which it is so often assailed, and show that this charge has no foundation either in its princi- ples or the influence which it has actually ex- erted upon the opinions of men ; for that the nation which has most assiduously cultivated it, has also done more to advance the doc- trines of natural theology, than any nation known to history. We conclude this part of the discourse, by showing that the Baconian philosophy is not 20 ANALYTICAL INTRODUCTION, like the ancient philosophies, adapted to the culture of one epoch and one people only; but that like Christianity it js catholic in its -spirit and equally suited to all times and to every people, and that it is likely to extend its blessings to all nations, and gather them under its wings as a hen doth gathe^r her chickens. I In the second part of the discourse, we en- ter upon the consideration of the Baconian method of investigation. This part is divided into two chapters. The first chapter treats in the first place, of the Aristotelian Logic, and shows that it analyzes the reasoning pro- cess, and developes the form in which every argument passes through the mind, and that this form is the syllogism. It then shows, that the truth of the conclusion of an argument is always assumed in the premises, and is not in reality a new truth : but merely a particular instance of a general truth already known, and stated in the premises. It is then shown that the a priori method of investigation is nothing more than a misapplication of the Aristotelian logic as a method of investiga- ANALYTICAL INTRODUCTION. 21 tion. The effect of this misapplication upon ancient philosophy, is then shown, and the peculiar errors produced by it, pointed out. This effect is then traced down through the middle ages of European history, and the futility of the philosophy of that period is signalized. We next enter upon the consideration of the method of investigation taught by Bacon in the Novum .Organon, and show that it is just the reverse of the syllogistic method of Aristotle, which had been previously used. it is shown that the Baconian method of in- vestigation proceeds from particulars to uni- versals, and that the syllogistic or a priori method proceeds from universals to particu- lars. And it is shown that the Baconian method of investigation is not a process of reasoning at all — is not carried on by rules of logic : but is carried on by rules of evi- dence. And that though the mathematics are applied to the verification of the inferen- ces of induction in the physical sciences, that still this does not take those sciences out of the paje of induction and put them within "%2 ANALYTICAL INTRODUCTION. the precincts of reasoning: the reasoning process being in such application of the math- ematics, a mere touch-stone to test the truth of the inductive conclusions, and not to elicit any new conclusion not already reached by induction. Analysis and synthesis are also considered ; and are shown to be in the sci- ences of contingent truth, inductive process- es and not processes of reasoning, and that they are what Bacon called the ascending and descending processes of induction. And as we show that induction is carried on by means of principles of evidence and not by princi- ples of logic, we enter upon the considera- tion of the nature of philosophical evidence ; and show that all evidence may be divided into analogy and identity ; and that the whole inductive process, as long as that process is founded on mere probability, no matter how great is the probability, proceeds on analogi- cal evidence. And we show that all the great discoveries in physical science have been made by the evidence of analogy. We then distinguish between philosophical anal- ogy, and rhetorical analogy ; and show that ANALYTICAL INTRODUCTION, 23 the distinction is an important one, and that for want of this distinction men have contin- ually fallen into error. And finally we evolve out of our analysis of the inductive process, the great fundamental principle of philosoph- ical evidence, which bears the same relation to induction, that the Dictum de omni et nullo of Aristotle, does to the syllogism. And thus we have rendered induction just as systematic as Aristotle did the syllogism. And surely it is much more difficult to develop a princi- ple which shall embrace in its application the innumerable particular instances which occur in every science or department of nature, and show the connection between them and the inductive inference properly inferrible from them, than it is to develop a principle which shall show the connection between the premises and conclusion of an argument : and therefore such a principle is so much the more important. Mr. Macaulay in his celebrated review of Bacon's writings seemed to think that no such principle as the one just mentioned could be developed — that no precise rule can be 24 ANALYTICAL INTRODUCTION. given, marking the difference between instan= ces from which a sound inductive inference can be drawn, and instances from which such an inference cannot be drawn. And with a levity characterized more by the spirit of a coquette, than of a philosopher-^ with strong- words and weak arguments — he has attempt- ed to ridicule by the reductio ad absurdum, the value of Bacon's delineation of the in- ductive process in the second book of the Novum Organon, He amuses himself, and as he supposed, his readers too, with a ludi- crous caricature of the inductive ocess, in showing that it is by it, that a man finds out that he has been made sick by the mince pies which he had -eaten. It would have been quite as philosophical, to have attempted to depreciate the inductive procesSj by showing that it was by that process, that Hudibras ar- rived at the conclusion that it was not neces- sary to have more than one spur ; because he had ascertained by actual experiment, that one side of his horse could not move without the other, and that therefore, if one spur could make one side go, it would make the ANALYTICAL INTRODUCTION, 25 other go too. Mr. Macaulay well knows that ridicule is not argument. And doubtless he would readily perceive, that the fact, that Hudibras " by geometric scale, Could take the size of pots of ale ; Resolve by signs and tangents, straight, If bread or butter wanted weight," does not detract from the dignity of New- ton's Principia or prove that the rules of geometry are useless. And yet he does not perceive the folly of attacking by ridicule, the development of induction which Bacon has given in the second book of the Novum Organon. But smitten with the ambition of critical display, he sacrifices truth to rhetoric. And in his attempts to reduce to absurdity, the reasonings of others, he plunges into that predicament himself. Flying upon the wings of antithesis, and in his onward course show- ing first one wing of the antithesis and then the other, in order that his readers may ad- mire their brilliancy and their contrast, and more intent upon the grandeur of his flight than the point to which he is moving, he is 3 26 ANALYTICAL INTRODUCTION. sometimes carried to the most preposterous conclusions. And on the point which we are now examining he goes the whole length of declaring that grammar and logic and rhetoric are useless studies. When it is a knowledge of these very studies, which has strengthened and plumed his own wings, and enabled him to soar aloft so boldly and gracefully, that we cannot but admire his flight, even when it is beyond the regions of truth and common sense. But not content with ridiculing induction by general remarks, Mr. Macaulay, as if to signalize its absurdity, ridicules it in all its de- tails, until his criticism rivals in the minute- ness, of its anatomy, the celebrated curse which Dr. Slop, at the request of Mr. Shan- dy, read aloud, to the so great horror of my uncle Toby. " We have heard (says he) that an eminent judge of the last generation was in the habit of jocosely propounding after dinner a theory, that the cause of the prevalence of Jacobinism was the practice of bearing three names. He quoted on the one side Charles James Fox, Richard Brinsley ANALYTICAL INTRODUCTION. 27 Sheridan, John Home Tooke, John Philpot Curran, Samuel Taylor Coleridge, Theobald Wolfe Tone : These were instantiae con- venientes. He then proceeded to cite in- stances absentiae in proxime : — William Pitt, John Scott, William Wyndham, Samuel Horsely, Henry Dundas, Edmund Burke He might have gone on to instances secundum magis et minus. The practice of giving chil- dren three names, is more common in Ameri- ca than England. In England we have a King and a House of Lords, but the Ameri- cans are republicans. The rejectiones are ob- vious. Burke and Theobald Wolfe Tone were both Irishmen; therefore the being an Irishman, is not the cause of Jacobinism. Horsely and Home Tooke were both Clergy- men; therefore the being a Clergyman, is not the cause of Jacobinism. Fox and V/ynd- ham were both educated at Oxford; and therefore the being educated at Oxford, is not the cause of Jacobinism. In this way our inductive philosopher arrives at what Bacon calls the vintage, and pronounces that the hav- ing three names is the cause of Jacobinism." 28 ANALYTICAL INTRODUCTION. " Here is an induction corresponding with Bacon's analysis, and ending in a monstrous absurdity. In what, then does this induction differ from the induction which leads us to the conclusion that the presence of the sun is the cause of our having more light by day than night ! The difference evidently is not in the kind of instances, but in the number of instances; that is to say, the difference is not in that part of the process for which Bacon has given precise rules, but in a circumstance, for which no precise rule can possibly be giv- en." Now we join issue with Mr. Macaulay and say that it is the kind of instances as well as the number of instances which constitute the difference between the two cases which he puts. For if the instances of the three names had been as numerous as the whole Jacobin party, though it would have been a marvellous coincidence, yet no man in his senses w r ould have believed that the bearing three names was the cause of the prevalence of Jacobinism ; and simply because, the in- stances are not of the kind from which an in- ductive inference can be drawn : they being ANALYTICAL INTRODUCTION. 29 the mere coincidence of chance, and not kindred facts conjoined by a law of nature. It is true that if every Jacobin had borne three names, it might have been inferred that there was some cause for such a conjunction of facts ; that their parents, perhaps, from some com- mon motive gave their children three names, just as the old Puritans from a common motive, gave their children whole verses of scripture for names. But under no circumstances what- ever could it be inferred that the bearing- three names was the cause of the prevalence of Jacobinism. The fact that the presence of the sun is the cause of more light by day than night is a fact in nature, and is support- ed as every fact in nature always is, by innu- merable analogies. But is the naming chil- dren a fact in nature — a work of the Creator? Is the bearing three names and the being a Jacobin, a relation established by the Creator of the universe ? Is there any analogy in na- ture from which it can be inferred that the one is the cause of the other? Certainly none. It might as well be supposed that the wearing pantaloons is the cause of one per- 30 ANALYTICAL INTRODUCTION. son's being a man, and the wearing petticoats, the cause of another person's being a woman, as that the bearing three names is the cause of one's being a Jacobin. This then is the difference between the two kinds of instances, and " the circumstance for which a precise rule can be given :' ? the one is the constant connection between two facts in nature, the other , the casual coincidence of two facts totally irrelevant, and dependent on the acts of man. Their difference is perceiv- ed intuitively, and therefore cannot be made plainer by illustration. Our remarks in the discourse, on analogy, appear to us, to throw light upon the subject. Mr. M acaulay after exhausting his weapons of ridicule, becomes very serious, and says "that the difference between a sound and unsound, or to use the Baconian phraseology, between the interpretation of nature and the anticipation of nature, does not lie in this — that the interpreter of nature goes through the process analzyed in the second book of the Novum Organon and the anticipator through a different process. They both per- ANALYTICAL INTRODUCTION. 31 form the same process. But the anticipator performs it foolishly or carelessly ; the inter- preter performs it with patience, attention and sagacity, and judgment. Now precepts can do little towards making men patient and attentive, and still less towards making them sagacious and judicious." Now these sober remarks of Mr. Macaulay are not entitled to one tittle more respect as exhibitions of truth than those which we have been examining. Precepts of no use! Why ; are not precept and example the only guide of man ? and is not the whole force of example in its being the expression of a precept? The mere general precept which lies at the foundation of the Baconian philosophy, that we should scrutinize with caution the phenomena of na- ture, before we draw our inferences, has rev- olutionized philosophy ; and yet it is gravely asserted, by one of the most brilliant writers, and adroit critics of the age, that precepts are useless in philosophical investigations, and in every thing else. We readily admit, that as long as induction is confined, to ascertain- ing what article of diet has made a man sick, 32 ANALYTICAL INTRODUCTION. or whether one side of a horse can move without the other, precepts are of very little use. But then, it must be remembered, that induction "resembles the tent which the fairy Paribanou gave to Prince Ahmed. Fold it, and it seemed a toy for the hand of a lady. Spread it, and the armies of power- ful Sultans might repose beneath its shade." When it is the toy for the hand of a lady, we may use it without the aid of precepts, but when it is spread out so that the armies of powerful sultans may repose beneath its shade, we cannot manage it by our unaided strength. Having thus, in the first chapter of the second part of the discourse, considered the Baconian method of investigation, in the sec- ond chapter, we consider the theory of mind assumed in that method. We show, there never has been, and that there never can be, more than two theories of mind : and these two theories are the theory of innate ideas, and the theory that all our knowledge is founded ultimately in experience. We show that the theory of innate ideas is the theory assumed in the a priori method of investiga- ANALYTICAL INTRODUCTION. 33 tion ; and that the theory that all our knowl- edge is founded ultimately in experience, is that assumed in the Baconian method of in- vestigation. It is shown that Plato was the leading philosopher amongst the ancients and Des Cartes amongst the moderns, who main- tained the theory of innate ideas ; and that both these philosophers maintained the a pri- ori method of investigation. It is next shown that Bacon had a distinct view of the the- ory of mind that all our knowledge is founded ultimately in experience ; and that this is the theory of mind which has been developed by Locke and Reid. We show that Locke solv- ed the great fundamental problem of this the- ory of mind, and showed that all our knowl- edge originates in sensation and conscious- ness. And that Reid established this theorv still more firmly by developing the great psy- chological laws which lie at the foundation of this theory, and which govern human belief in the knowledge derived through these orig- inal sources of information. He developed the law which governs our belief in the tes- timony of sensation, and the law which gov- 34 ANALYTICAL INTRODUCTION. erns our belief in the testimony of concious- ness. He also developed the law which gov- erns oar belief in the testimony of memory, and the law which governs our belief, that the future will be like the past, and that like causes will produce like effects. This last is the fundamental law of induction. And thus we trace up the Baconian method of in- vestigation through the theory of mind which it assumes in every step of knowledge until we trace the process up to the very first im- pressions made upon the senses, and we show the psychological law for every act of the mind in the process. We next examine the philosophy of Kant, and show that his doctrine of a priori conceptions of the rea- son, has the same logical characteristics as the doctrine of innate ideas; and that it assumes the a priori method of investigation. We have therefore in the two chapters of this part of the discourse, exhibited an outline of a complete system of logic in the largest sense of the term ; and furnished in it a touch- stone of philosophical criticism by which the reasonings of all philosophies may be tested. ANALYTICAL INTRODUCTION. 3«5 In the third part of the discourse, we ap- ply the second part by way of philosophical criticism, to Lord Brougham's Discourse of Natural Theology, and Hume's Essay on a special Providence and a future State. We show that Lord Brougham in the very outset commits a logical blunder, which vitiates much of his subsequent reasonings. And that he does not solve the problem which he has pro- posed to himself; but that he always dodges it, or passes it over, by a mere assertion. We show that this results from his overlooking, some of the logical and psychological princi- ples which we have developed in the second part of our discourse. We then show how by an application of these principles, the problem which Lord Brougham has proposed to himself can be solved. We next show that the great doctrine of Lord Brougham's discourse, that Natural Theology is a branch of the inductive or Baconian philosophy, and is founded on the same sort of evidence as that philosophy, had been distinctly advanced by Bacon, and set forth with the most accu- rate discrimination ;. and from the fact that 36 ANALYTICAL INTRODUCTION Brougham comments in his discourse up- on this portion of Bacon's writings, we are at a loss to determine whether he could have misunderstood Bacon, or whether he wished to pervert Bacon's doctrine, in order that he might have the credit of having first shown the true place of Natural Theology amongst the sciences. After having examined Lord Brougham's discourse, we proceed to examine Hume's Essay on a Special Providence and a future State ; and we show by an application of the psychological and logical principles developed by us in the second part of the discourse, that the whole fallacy of Hume's doctrine consists in his confounding an intelligent Creator with a mere physical cause. And we show that this is the clue by which the sophistical labyrinths of his argument are to be traced. As soon as the distinction between an intelligent Creator and a mere physical cause is applied to Hume's reasonings, his whole argument point after point, falls to the ground, as if touched by the wand of a talis- man ; and we feel astonished that the essay ANALYTICAL INTRODUCTION. 37 should, by the apparent strength of its for- tresses, have so long kept off the attacks of natural theologians ; and should at this day be considered so formidable as to lead Lord Brougham to remark that, "we may the rath- er conclude that it is not very easily answer- ed, because in fact it has rarely if ever been encountered by writers on theological sub- jects." And it is remarkable that no writer on natural theology, as well as we can recol- lect, has shown the importance in our rea- sonings on natural theology, of the distinct- ion between an intelligent Creator and a mere physical cause, and yet it is the confounding of so obvious a distinction that has caused the chief difficulty on this subject. We have shown that with this distinction there is no difficulty whatever in maintaining on the prin- ciples of the inductive philosophy, the truth of natural theology ; but that without this distinction, natural theology must fail. In the fourth part of the discourse, the connection between philosophy and revela- tion, is examined. It is shown, that when we interpret revelation according to the light 4 38 ANALYTICAL INTRODUCTION. of reason, we in reality, interpret it accord- ing to philosophy, as reason has no light, but that of experience, and this is philosophy. From this consideration, it is shown that the proper way to interpret the scriptures, is by a. sound interpretation exercised upon their own proper teachings. It is also shown, that the scriptures, on account of the fact, that their author knew the future as well as the present and the past, and has directed some of his doctrines accordingly, cannot be inter- pretted altogether as a mere human writing. It is also shown, that the scriptures, are not confined to the doctrines of revelation, but con- tain much which lies within the province of philosophy ; and as they do not teach philoso- phy, but theology, they must follow philoso- phy in all things upon which it can speak au- thoritatively as belonging to its province. A difference however, is pointed out in the ap- plication of this rule, between physics and psychology ; as the scriptures throw no light over physical science, but throw much over psychology. From this view of the connection between ANALYTICAL INTRODUCTION. 39 philosophy and revelation, it is shown that the a priori method of interpreting the scrip- tures, — of forcing one's philosophy upon its teachings — is altogether erroneous. That we should never subordinate revelation to philos- ophy. And it is shown, that the neglect of this great truth has been the chief source of error in every age of Christianity. That at the present day, the scriptures are continually perverted by subordinating their teachings to philosophy. This is shown to be the case, in the recent work of Prof. Bush on the Resur- rection; and to be the case, in the heterodox theology of New England ; and also to be the case, in the perversions of theology in Germany and France. It is shown too, that during the middle ages, the philosophy of Aristotle exerted a pernicious influence over Christianity by cramping its vital spirit within its own dry and meagre forms. It is shown also, that in the earliest ages of Christianity, the scriptures were perverted by forcing upon them the doctrines of the different systems of philosophy which then prevailed. The Eb- ionites, the Gnostics, and the Platonists, all 40 ANALYTICAL INTRODUCTION. perverted; the doctrines of revelation, by forcing upon the scriptures in their interpre- tation of them, the peculiar doctrines of their respective philosophy. And thus, the a priori method of interpretting scripture, is as false, as the a priori method of interpretting nature. It is next shown, that there is however a philosophy which is consistent with Christian- ity in both its method of investigation and its principles — a philosophy which bows down in humility before Christianity, and acknowl- edges its ignorance of the great truths which it proclaims. This is shown to be the Baco- nian or Inductive philosophy. The inductive method of investigation is shown, to corres- pond with the nature of Christianity. The great truths of Christianity upon which sal- vation depends, are shown to be, like the truths of nature upon which natural life de- pends, so plain, that "the way-faring man though a fool need not err therein." The great cardinal doctrine of justification by faith, and also the doctrine of the paramount im- portance of truth in the conversion of man, ANALYTICAL INTRODUCTION, 41 which holds so prominent a place in the sys- tem of theology called evangelical, are shown to stand under those psychological laws, which the inductive philosophy has discover- ed. And thus the evangelical theology and the Baconian philosophy are shown to be parts of one great system of thought. We have then, in the first part of the dis- course, shown the nature of the Baconian philosophy ; in the second part, the Baconi- an method of investigation, and the theory of mind assumed in that method; in the third part, we have shown, how by the appli- cation of the logical and psychological princi- ples developed in the second part, it may be used as a touchstone of philosophical criti- cism, and at the same time it is shown, that na- tural theology is a branch of the inductive phi- losophy; and in the fourth part, we have shown the connection between philosophy and revelation. And now, all that we ask of the reader is, that he will not read one part of the discourse, without reading the whole ; as the discourse is arranged in a sort of logi- cal perspective, so that every part casts light 4* 42 ANALYTICAL INTRODUCTION. upon the others, and it is impossible to see the full import of either part without reading them all. PART THE FIRST INFLUENCE OF THE BACONIAN PHILOSOPHY, In every age of the world, since the human family has been so numerous as to be divided into separate communities, some one nation has exerted a predominant influence over the rest. This appears to be the economy of civ- ilization. The Grecian Republics, (for they all were but one nation,) and Rome, in their successive order in history, have, of all the nations of antiquity, exerted the most import- ant influence on the destinies of man. But, in modern times a new order of civilization has arisen; and for more than two centuries, England has stood at the head of this new order of things. Enthroned upon the riches of a universal commerce, enlightened by the knowledge of every science, armed with the power, and accomplished with the embellish- 44 THE BACONIAN PHILOSOPHY. ments of every art — baptized into the spirit of Christianity, she is influencing and control- ling the destinies of the human race towards a glorious consummation. In the progress of this civilization, there have been three great revolutions, the religi- ous, the philosophical, and the political. After the human mind had thrown off the coercive authority of the Papal Church, the moral au- thority of the ancient philosophers still re- mained ; and what Luther did in the eman- cipation of the mind from the first, Bacon did in the emancipation of the mind from the last. Luther burnt the Pope's bull in 1520, and Ba- con published his Novum Organon in 1620. The religious revolution, therefore, preceded the philosophical, and both of these, the poli- tical. Not, however, that these revolutions did not move on simultaneously ; but, that in their progress, they were in advance of each other, in the order which we have indicated. Though they grew together they differed in maturity. Their crises were successive. Per- haps, the divine wisdom is displayed in this order of things — perhaps any other order is THE BACONIAN PHILOSOPHY. 45 impossible in the moral economy of the world : it being necessary that the restraints upon man, should be thrown off, not all at once, but separately, as he advances in mental and mor- al improvement These then, are the move- ments, which Europe has made in civilization. She has thrown off religious despotism, she has thrown off philosophical despotism, she has thrown off political despotism. And she has advanced to this position, through many a bloody agony. The treasures of the indus- try of ages have been spent, the chivalry of thousands of heroes, the studies by day and by night of scholars and philosophers, the genius of poets exhibiting in their composi- tions those actions which ennoble the soul, the patriotic and humane sentiments of orators clothed in the thunders of impassioned dic- tion — all these have been spent in purchasing the civilization of modern Europe. It be- comes then, an important inquiry to ascertain the character of the philosophy of that peo- ple, into whose keeping, so far as human a- gency is concerned, the destinies of Europe 46 THE BACONIAN PHILOSOPHY. appear, in the progress of history, to have been confided by divine providence. We will, therefore, pass over the religious and political revolutions, and even the litera- ture of modern times, and confine ourselves entirely to the philosophical revolution which originated in England, and which is -exerting so important an influence over the destinies of man, through the agency of that great people. We propose then, to sketch the rise and pro- gress of the most wonderful philosophical rev- olution, and the most glorious in its results up- on the pursuits and happiness of man, of any within the whole history of the world. We propose to give some account of the philoso- phy of utility — the philosophy of lightning rods, of steam engines, safety lamps, spinning jennies and cotton jins — the philosophy which has covered the barren hills and the sterile rocks in verdure, and the deserts with fer- tility — which has clothed the naked, fed ti*e hungry, and healed the sick — the philosophy of peace, which is converting the sword into the pruning hook, and the spear into the THE BACONIAN PHILOSOPHY. 47 ploughshare. This is the philosophy of which we propose to give some account.. It was Lord Bacon, who launched the hu- man mind upon this new career of discovery. He is the great reformer,- who stands at the head of the . teachers of this philosophy. Physical nature seemed perfectly impenetra- ble to the acutest intellects of the ancients. They could not get over even the threshold of physical science. Indeed,.they cannot be said to have had any natural philosophy at all ; so absurd were all their doctrines about physical nature. Neither did the philosophers of the middle ages, with all their assiduity, succeed in exploring this field of knowledge. And, though the discoveries of Copernicus, Kepler, Galileo and Tycho Brahe show that Provi- dence was preparing the way for a new era in physical science, and the discoveries of Roger Bacon in the thirteenth century indicate the same fact, yet it remained for Lord Bacon to generalize the idea which philosophers were begining to see obscurely and in single instan- ces, and to reveal to the philosophical world, what it had been prepared to comprehends — 48 THE BACONIAN 1 PHILOSOPHY. That true philosophy must be connected with the arts, that while it satisfies the highest facul- ties of the speculative intellect it may be appli- ed to the physical wants, and the general well-- being of man. That living as we do in a world where general and permanent laws ob- tain, and under their dominion, it is the object of natural philosophy to> ascertain these laws, in order that we may not, in our endeavours to promote our comforts, act against these laws, and thus attempt impossibilities ; and also, that " these laws are not only invincible opponents, but irresistible auxiliaries. " Ba- con wished to make every power of nature work for man, the winds, the waters, gravity, heat and all the mighty energies, which lie like the fabled giants of old under the moun- tains. These he wished to unloose from their fetters, and bring as servants under the domin- ion of man. Such are the grand conceptions which Bacon proclaimed to the world. Scarcely had Bacon published his writings before they were republished upon the con- tinent of Europe. The treatise De Augmen- tis was republished in France in 1624, the THE BACONIAN PHILOSOPHY. 49 year after its appearance in England; and it was translated into French in 1632. Editions were also published in Holland in 1645, 1652 and 1662. The Novum Organon was thrice printed in Holland, in 1645, 1650 and 1660; and men of every cast in the higher walks of life'on the continent of Europe were conver- sant with his writings. Gassendi, Des Cartes Richelieu, Voiture, and at a later period Leib- nitz, Boerhave and Puffendorf were loud in his praise. Indeed, his fame spread beyond the bounds of his own country, more rapid- ly than that of any philosopher within the whole history of letters. What an impulse, then, must the philosophy of Bacon have given directly and indirectly to the progress of the human mind upon the continent of Eu- rope ! for its advances there, have been made by pursuing the Baconian method of investi- gation. But let us see the progress of his philosophy in England, and cite some exam- ples of the leading discoveries which have been made by the Anglo-Saxon race. Not long after the death of Lord Bacon, in 1626, the Royal Society of London was es»- 5 50 THE BACONIAN PHILOSOPui. tablished for the promotion of the science^ and all England resounded with his praise. The philosophers of England almost adored his genius. They felt that he had a true En- glish mind; That he was the father of En- glish philosophy. That the English mind had at last given to it a method of philosophi- zing suited to its practical and common sense turn. And, behold the results written upon the glorious records of English philosophy ! In every department of physical science, . England has made the leading discoveries; and other nations, though their scientific la- bours have been so brilliant, have done little more than extended her researches and veri- fy her theories. In physiology, the two greatest discoveries were made by philoso- phers of the British isle. Harvey discover- ed the circulation of the blood, and publish- ed his treatise Exercitatio de motu cordis, as early as 1628. He was the cotemporary and intimate friend of Bacon. Sir Charles Bell discovered that there are two distinct sets of. nerves, those of sensation and those of mo- tion. And it is worthy of remark that both THE BACONIAN PHILOSOPHY. 51 these great discoveries ; so important to medi- cal science, were discovered by considera- tions founded upon the evidence of final causes. Harvey discovered the circulation of the blood, by reflecting on the use of those valves in the veins whose structure is such as to prevent the reflux of the blood towards the extremities. And Sir Charles Bell tells us in a note to his Bridgewater treatise on the hand, that the views taken of the nervous system in the chapter of that work on " Sen- sibility and Touch, V where the uses and en- dowments of the different nerves are consi- dered, guided him in his original experiments by which he established the great doctrine, that there are two sets of nerves prevading the whole animal system. By observation and experiment, he had ascertained that each nerve of sense has a distinct endowment, so that one nerve can never subserve the pur- pose of another, the nerve of vision for ex- ample, can never serve for hearing, nor that of taste for smelling, and so forth. And he further observed, that each of these nerves arose from a distinct part of the brain. He 0% THE BACOxMAN PHILOSOPHY. therefore concluded; that for the brain at least; different nerves have different functions derived from the spots whence they originate. It therefore occurred to him, that perhaps, the two great nervous functions of the body, sensation and motion, are performed by differ- ent nerves having different functions. This however did not appear to be the case, as far as observation and experiment had been made ; for on cutting the trunk of a nerve, a limb was found to be deprived of both feeling and motion. Still, such was the force of the inductive principle which he had established relative to the nerves of the head, that he con- jectured that what appeared to be one nerve, might in reality be a bundle of nerves tied and packed together for convenience of dis- tribution. And on further investigation, he discovered, that these apparently single nerv- es, did really run into the spinal marrow by two roots, one originating in the anterior, the other, in the posterior column. He then pro- ceeded to experiment upon the important fact thus discovered. He laid bare the spine of an ass, and on irritating the anterior root, the THE BACONIAN PHILOSOPHY. 53 muscles supplied by the nerve were convul- sed, while a touch of the posterior root made the animal wince, as from pain. But though this was strong proof, that mo- tion belonged to the anterior root, and sensa- tion, to the posterior, still, it was not conclu- sive ; as it could not be determined with cer- tainty, whether the pain indicated by the ani- mal when the nerve was irritated, did not re- sult from wounding the raw surface. In pur- suing his investigations., he observed, that the nerve to which he had ascribed sensation, throughout the whole course of the spine, had a ganglion or bulge on its roots, and that the nerve to which motion had been ascribed, had none. This difference in structure, which in itself is some evidence of difference in function, became a salient point to a cer- tain proof, that there is a difference in the functions of the two sets of nerves. For upon further investigation, he discovered a nerve of the head which arose from two roots, on one of which there was a ganglion, but none on the other ; and that these nerves in- stead of being bound together in one sheath 54 THE B AC OMAN r,HI LOSOFIi-Y, as is the case with the spinal nerves, run sep- arate, and also instead of being covered with much flesh, come to the very surface of the face. Inferring therefore, with that sagacity which can interpret every intelligible indica- tion, that these nerves were specially design- ed to give sensation and motion to the head, he by a slight puncture of the root, ascertain- ed that the n^rve with the ganglion on it, was a nerve of sensation. And thus the strongest proof was adduced, that the nerves of the posterior column of the spine anala- gous to this one in structure, were so in func- tion, as had been supposed; for this nerve being separate from any other, and lying at the very surface, could be punctured without wounding a raw surface, and still it exhibited indications of a function analagous to that which had been ascribed to those analagous to it in structure. And thus the fact, that the two great nervous functions of the body, sen- sation and motion , are performed by two dif- ferent sets of nerves having different endow- ments, was discovered. Modern medicine also may be said to THE BACONIAN PHILOSOPHY. 55 have arisen in England. Sydenham, who had maturely studied Bacon's writings, laid the foundation of the science of medicine by pointing out, both by precept and ex- ample, the true method of observing the symptoms of disease, and of applying cura- tive means according to the natural indica- tions. Since his time, medicine has, by the aid of its auxiliary sciences, made rapid progress: but still his works are of much value, even yet, on account of their profound general views. And John Hunter may be said to have originated the science of com- parative anatomy and physiology, by bringing experiment into the study of these branches of knowledge, thereby showing how to lay open the great mysteries of the human or- ganization. Surgical and medical pathology, which before his time were entirely conjec- tural, assumed from his principles a more pos- itive character. But to a disciple of Hunter, belongs the most important as well as the most extraordinary discovery ever made in medicine. From the fact that small-pox, like some few other diseases, cannot, as a general 56 THE BACONIAN PHILOSOPHY. fact, afflict the same subject but once, the practice of inoculation had been introduced ; as the inoculated disease, on account of the healthful condition of the patient when the virus is introduced into his system, and the treatment to which he can be subjected by way of preparation, was found less virulent than the disease taken in the natural way^and yet retained its power to protect from a se- cond attack. Though this was true, still thousands died of the inoculated disease ; and many contracted the disease from the inocula- ted patients; and thus was ever kept open new sources of the dreadful malady. Yet so awful was the natural disease, that inoculation though so terrible an expedient, was justly considered a valuable remedy. In this state of medical science relative to this awful disease, Dr. Jenner of England, having when a youth, heard a country girl re- mark, that she was not afraid of small-pox, for she had had the cow-pox, caught at the idea, and continued to enquire and reflect about it, year after year, until he evolved the important doctrine of vaccination. With that THE BACONIAN PHILOSOPHY 57 inductive sagacity which seizes upon those analogies between dissimilar things that are the clues by which the labyrinths of nature's se- crets are to be explored, he conceived the bold idea of introducing the disease of a beast into the human frame, as a means of preventing a worse disease natural to man. From a careful examination of facts suggested by the remark of the country girl he had been led to believe, that cow-pox, when taken by milk-maids from the udders of cows, will prevent the small- pox. He therefore conjectured that it might advantageously supersede the inoculated small- pox, as it was a perfectly harmless disease even when taken in the natural way, and would, he supposed frojn analogy to the small-pox, be still milder when taken by inoculation, and yet like inoculated small-pox,, would retain its protecting power. Experi- ment was therefore made. On the four- teenth day of May 1796., be inoculated a boy in the arm, with vaccine virus taken from a pustule on the hand of a young woman who had been infected by her master's cows. The disease took effect. On the first of the sue- 68 THE BACONIAN PHILOSOPHY. ceeding July he inoculated the hoy with small-pox virus, and as he had predicted, without the least-effect. And thus was made a discovery which has saved the lives of mil- lions of the human race; and has rescued youth and beauty from the loathsome em- braces of a disease, which even when it spares the life of its victim, leaves upon him forever the indelible marks of its malignity. We delight to record, such triumphs of sci- ence over human woe ; and to listen to the joy of the great discoverer in announcing his success to the world. u While the vaccine discovery (says Jenner) was progressive, the joy I felt at the prospect before me, of being the instrument destined to take away from the world, one of its greatest calamities, blend- ed with the hope of enjoying independence and domestic peace and happiness, was often so excessive, that in pursuing my favourite subject among the meadows, I have some- times found myself in a revery. It is pleas- ant to me to recollect, that these reflections always ended in devout acknowledgments to THE BACONIAN PHILOSOPHY. 59 that being from whom this and all other mer- cies flow. " In Chemistry too, the greatest discoveries have been made in England. The laws of chemical combination; which are of so much practical as well as scientific utility, were dis- covered by Dalton. But in showing what England has done for Chemistry, we must not give too much prominence even to this grand discovery, though it extends over the whole domain of chemical investigation, and lies at the very foundation of the science. For not only have other brilliant discoveries in chemistry been made in England, but indeed, modern chemistry may be said to have origi- nated there, or rather in the British isle. In 1752 Dr. Black of Edinburg, in experiment- ing with the alkalies and alkaline earths discovered, that causticity (which had been commonly believed to be acquired by lime from the fire in the process of calcination, which is then called quick-lime, and that all other alkaline substances derived it from the quick-lime, as they with the exception of mag- nesia can only be rendered caustic by being., 60 THE BACONIAN PHILOSOPHY. treated with it) is in reality owing to the loss of an aeriform substance with which they had been combined, and that they become mild again by a re-union with that substance. This aeriform substance or gass, which is now called carbonic acid, Black called fixed air, to denote that it is found fixed in bodies as well as in a separate elastic state. He dis- covered that this fixed air is separated from al- kalies and alkaline earths by heat, or by acids which have a greater affinity for them than the fixed air has. He also discovered that the very same elastic substance was produced by the fermentation of vegetable bodies, also by the combustion of charcoal, and that it is also evolved in the breathing of animals. The importance of this discovery consists in the fact that contrary to the universal be- lief, it was thereby discovered that atmospher- ic air is not the only permanently elastic body, but that there are others which though trans- parent and invisible like atmospheric air, yet possess very different qualities, and are ca- pable of loosing their elasticity by entering into chemical combination with either solids THE BACONIAN PHILOSOPHY. 6T or liquids, and of regaining their elastic state on being separated from them. What a new view of things, must the discovery thus made, that the solid marble is nothing but dust bound together by an invisible gas, have given ! What a wide field of investigation did this strange insight into nature, open be- fore the philosopher ! And Black made another discovery quite as remarkable as this. About the year 1763, from the fact ascertained hy him, that when heat converts a solid into a liquid, as when ice is reduced to water, by putting it into its own weight of hot water, or a liquid is con- verted into a vapour, the liquid or vapour re- sulting is no hotter than the solid or liquid from which they are produced, though in the process a great amount of heat has actually entered into the substances; and from the fact, that when* the water freezes or the va- pour condenses: am unexpected amount of heat is given, out^, he: : drew the inference, that the quantity of heat which; could not be indi- cated by the thermometer, remained latent m the body. For in converting water into ice ? , (32 THE BACONIAN PHILOSOPHY. as much as one hundred and forty degrees of heat are expended, and yet the water will be as cold as the ice — the thermometer will stand at thirty two (freezing point,) instead, as might be expected, at one hundred and seventy two. And thus was revealed the mysterious doctrine of latent heat. This discovery and that of fixed air are auxiliary to the illustration of each other, and are the basis, or at all events, the chief salient points of modern chemistry. As it was now ascertained that there are other permanently elastic bodies besides atmospheric air, and as it appeared to be a fundamental fact in nature, chemical investigation necessarily took the direction which it indicated, as the way to important truths ; and a mere talent for experiment might now proceed with the most brilliant success in a path, which none but the highest genius for induc- tive research could have laid open to the in- quirer. And such was the course of chem- ical enquiry. All chemists at once entered upon the field of pneumatic chemistry, which Black had laid open. Dr. Priestly THE BACONIAN PHILOSOPHY. 63 in 1774 discovered oxygen gas, by exposing red-lead in a close vessel, to the sun's rays concentrated by a burning glass, when a per- manently elastic aeriform body was evolved, which had the property of greatly increasing the intensity of flame. At a later period^ he discovered the important fact that the absorp- tion of this gas in the act of respiration gives its red colour to the arterial blood ; and he also found that when plants grow inclose ves- sels, and restore the purity of the air in which a candle has been burnt, or an animal breathed, a fact which he had before discov- ered, they do so by evolving this gas. He also discovered nitrogen gas, about the same time that Dr. Rutherford of Edinburgh did, by the fact, that if air is exposed to sulphur and iron filings, its bulk is diminished, and the residue is lighter than common air and unfit for respiration, which residue is ni- trogen. And Watt and Cavendish who had entered upon this new field of investi- gation, discovered some of its most important truths. The composition of water, the knowl- edge of which is an element in so many chem- 64 THE BACONIAN PHILOSOPHY. ical reasonings as to make it one of the most prolific of chemical discoveries, was discov- ered by Watt and verified by Cavendish who burnt oxygen and hydrogen in a dry glass ves- sel, when a quantity of pure water was gen- erated equal in weight to that of the gases which had disappeared in the formation of water, a proof incontestable, that the water was formed of the two gases which had dis- appeared. Cavendish showed also the first example of weighing permanently elastic bodies ; and thus gained an important con- troul over these evanescent substances. He also discovered that nitrous acid is composed of the two gases deprived of latent heat, which compose our atmosphere, oxygen and nitrogen. But it was the glory of another English- man to make the most brilliant discoveries which have yet adorned the history of chem- istry. Sir H. Davy with an experimental skill and a daring intrepidity which have never been excelled, entered at this stage of the science into the field of chemical inqui- ry which his countrymen were exploring THE BACONIA.NT PHILOSOPHY, 65 with such extraordinary success. And as if it were specially designed to be wielded by his giant arm, in the noble conquests of science, Volta had just invented the pile which bears his name. Immediately after its invention, it was sent to England, and Nicholson and Car- lisle discovered that water could be decom- posed by its action. They plunged two plati- num wires connected with the opposite poles of the battery, into the same cup of water, without their touching each other, when hy- drogen gas was disengaged at the negative wire, and oxygen at the positive, each passing off in bubbles, which when collected in sepa- rate tubes were found to be pure, and in the exact proportion of which water consists. With this wonderful fact before him, Sir H. Davy exposed other compound bodies, such as acids and salts, to the action of the battery, and all without exception were decomposed, one of their elements appearing at one side of the battery, and the other at the opposite extremity. And he found that there was a uniformity in these decompositions. That their law was, that the acids and oxygen and all 6* 66 THE BACONIAN PHILOSOPHY. bodies of a like kind are transferred to and ac- cumulate around the positive pole, while hy- drogen, metals, alkalies and such like bodies are transferred to the negative pole ; and he discovered that these transfers will take place through considerable spaces, and that acids would pass through vessels containing alkaline solutions, and alkalies, through vessels filled with liquids containing free acids, without the least combination, and appear at their respec- tive poles with their peculiar properties. Sir H. Davy observing the analogy between these phenomena and the attractions and repul- sions effected by ordinary electricity, inferred that chemical attraction is an electric force ; and that the reason why any substance, as water for instance, is decomposed, by a batte- ry, is that one end of the wire has a greater affinity on account of its intense electrical condition, for oxygen and the other for hy- drogen, than these elements have for each other. Guided by this view of the nature of chemical attraction, he inferred that any compound substance whatever, might be de- composed by a battery of sufficient power, by THE BACONIAN FHIL080FHY. 67 subverting the chemical affinity of its ele- ments, in presenting to it, a wire of such in- tense electrical condition as to attract its ele- ments with more force, than they attract each other. Directing his experiments according- ly, he succeeded in decomposing the alkalies and alkaline earths, showing that they are composed of oxygen and an inflamable me- tal, the oxygen accumulating at the positive pole, and the metal at the negative, thus bringing to light entirely new substances in these inflamable metals, and rendering still more probable by the decomposition, the cor- rectness of his view of the nature of chemi- cal attraction. What a grand step was this from the sim- ple discovery of Black, that an elastic fluid is sometimes found fixed in a solid, as carbonic ascid in limestone ! For here the lime which Black considered an element and which had revolved as an element at the points of other batteries, is now shown to be composed of an inflamable metal, and a gas which is one of the elements of the very gas which Black had discovered to be the ligature which binds 68 THE BACONIAN PHILOSOPHY. limestone together. And thus the path of inquiry which Black opened, had led to such rich discoveries. But the career of discovery does not end here. The field of chemical research which had been laid open by Black, had been so successfully explored, that Sir Humphrey Davy was enabled to lay the foundations of agricultural chemistry, upon the truths which had been discovered, and thereby elevate the culture of the soil from the most empirical drudgery, to a scientific art. It had been ascertained that vegetables are composed of the four simple gases, Carbon, Hydrogen, Nitrogen, and Oxygen, which the disciples of Black had discovered, and a mi- nute quantity of inorganic matter. The question then occurred, whence do plants obtain these elements? And it is at once seen that they must obtain them either from the atmosphere or the earth ; or from both. It had long been known that marine plants reaching the enormous height of three hun- dred and sixty feet, and which nourish thous- ands of marine animals, grow upon the naked THE BACONIAN PHILOSOPHY. 69 rocks. But as the surfaces of these rocks undergo no change, it was obvious that the plants did not draw their nourishment through their roots from them. They must then derive it through their leaves from the sea-water, in which they float, spread out in their enor- mous ramifications, so that every part of the plant is presented to the surface of the water. This is made clear, by the fact that sea-water is found by analysis to contain all the constit- uents, carbonic acid, ammonia and the alkaline and earthy phosphates and carbonates, re- quired by these plants for their growth, and which are found to be the constituents of their ashes. It is therefore seen that these plants may derive all their nourishment through their leaves. But do terrestrial plants derive all their nourishment through their leaves? This cannot be so; because the only medium from which these plants can derive nourishment through their leaves and bark, is the atmosphere; and it does not contain, like sea- water, all the elements of plants. Its constituents are oxygen, nitrogen together with watery vapour, carbonic acid 70 THE BACONIAN PHlLOSOPHf. and ammonia. And these are not all the constituents of plants — the inorganic matter being wanting. Terrestrial plants, must therefore derive some nourishment at least, from the soil. For though the earth is a magazine of organic matter as well as inor- ganic, yet as plants are found to flourish up- on soils where the quantity of carbon and ni- trogen contained in them cannot have been in the soil, as well as from many other facts, the conclusion is irresistible, that terrestrial plants derive their nourishment, from the atmosphere as well as the soiL Thus is opened the whole field of agricul- tural chemistry. For it is obvious, that if plants are composed of certain elements, some of which are derived from the soil, and others from the atmosphere, it is necessary that the soil and the atmosphere should each contain the elements proper to it, as food to the plants. For otherwise, the plants must be as it were starved to death. And as it is certain, that the atmosphere has not changed since the earliest period at which an accurate analysis of it has been made, we may conclude, as we THE BACONIAJf PHILOSOPHY. 71 know how its equilibrium is kept up, that it will always contain those elements of plants which it is its province in the economy of na- ture, to furnish to vegetation. But this is not the case with the soil ; for by a succession of crops, all the elements necessary for the growth of plants may be removed from the soil ; and then the plants cannot grow from want of food. It is seen then how important it is to know what elements of plants are furnished by the soil, and what by the atmos- phere. For otherwise,, we might, at a great expenditure of labour and capital be endea- vouring to furnish to the soil, the elements which the plants derive from the atmosphere ; whereas all that is necessary, is to furnish those to the soil, which it gives to the plant. And as chemistry informs us of the nature of manures, what elements each kind contains, we are enabled to put on the soil, the precise kind it wants; and thus make an economical expenditure of labour and capital, and also, direct our means with certain success. By such a course of reasoning did Sir H. Davy lay the foundation of agricultural chemistry ; 72 THE BACONIAN PHILOSOPHY though some facts here exhibited have been discovered since his time. The first inductive generalization ever made in electricity^ was made by Grey and Wheel- er of England, who discovered that some sub- stances are conductors and others non-conduc- tors. And the great truth that the lightning of Heaven is identical with electricity was discovered by one speaking the English as his vernacular language. Franklin, by the beautifully simple apparatus of a kite having a key attached to the low^r end of a hempen cord ; and being insulated by means of a silken thread; by which it was fastened to a post; demonstrated that the electric fluid and light- ning are identical. The kite was raised, while a heavy cloud was passing over ; and after some time; the loose fibres of the hemp- en cord began to bristle. Franklin touched the key with his knuckle ; and the electric spark was received; and thereby the identity of electricity and lightning was verified. The fundamental truth of optics was also dis- covered in England. Newton discovered that a beam of. light; as emitted from the sun ; con- THE BACONIAN PHILOSOPHY. 73 sists of seven rays of different colours pos- sessing different degrees of refrangibility. This great discovery was made by darkening a room and boring a hole in the window- shutter, and letting a convenient quantity of the sun's light pass through a prism. The light was so refracted by its passage through the prism, as to exhibit all the different colours on the wall, forming an image about fi.\e times as long as it was broad; instead of forming a circular image, according to the received laws of refraction at that time, and of a white colour, according to the nature of light as then understood. In order to ascertain the true causes of the elongation and colours of the image, Newton then placed a board with a small hole in it, behind the face of the prism and close to it, so that he could trans- mit through the hole any one of the colours, and keep back all the rest. For example, he first let the red light pass through and fall on the wall. He then placed another board, with a hole in it, near the wall where the red ray fell, so as to let it pass through the hole in the second board, and then he placed a prism 7 74 THE BACONIAN PHILOSOPHY. behind this board, and let the red light pass through it near the wall. He then turned round the first prism so as to let all the colours pass in succession through these two holes, and he marked their places on the wall, and he saw by their places, that the red rays were less refracted by the second prism, than the orange, the orange, less than the yellow, and so on, all being less refracted than the violet. From this experiment, Newton drew the grand conclusion that light is not homogeneous, but is composed of rays of different colours and of different degrees of refrangibility. And the greatest of all human discoveries, the universality of the law of gravity, the foundation of physical astronomy, was diseov^ ered in England. Copernicus had discover^- ed the motion of the earth on its axis around the sun ; Kepler, that this motion around the sun, is in an elliptical orbit, with the sun in one of its foci ; and that an imaginary line drawn from the planet in its revolution, to the sun, describes equal areas in equal times ; and that the square of the time that the planet takes THE BACONIAN PHILOSOPHY. 75 in moving around the sun is equal to the cube of its distance from that body. This is the starting-point where the discoveries of the English begin. It remained to inquire into the causes of these general facts which had been discovered by Copernicus and Kepler. In the year 1666., Newton, while sitting alone in his garden and reflecting upon the nature of gravity which causes all bodies to descend towards, the centre of the earth, con- sidering that, this power suffers no sensible diminution at the greatest distances from the centre of the earth to which we can reach, being as great on the summits of the highest mountains a& at the -bottom of the deepest mines, conjectured that perhaps it extended further than was commonly supposed. He therefore began to consider what would be its effects if it extended to the moon. That the motion of the moon was affected by this power, he conceived to be beyond a doubt; and further reflection led him to suppose that this body might by this power be held in its orbit around the earth. For, though gravity suffered no sensible diminution at the 76 THE BACONIAN PHILOSOPHY. comparatively small distances from the centre of the earth to which we can go, yet he thought it highly probable, that it was great- ly diminished at the distance of the moon, and that therefore it did not cause that body to fall to the earth. And he inferred, that if the moon be held in its orbit by the principle of gravity that the planets also must be held in their orbits by the same power ; and that by comparing the periods of the different planets with their distances from the sun, he might ascertain in what proportion the power by which they were held in their orbits de- creased. By this process he arrived at the conclusion that it decreased in the duplicate proportion, or as the square of their distances from the sun. In order then to test the truth of the conclusion, that the law of the force by which the planets are drawn to the sun was that it decreased as the square of their distances from that luminary, he endeavored to ascertain if such a force emanating from the earth and directed to the moon was suffi- cient to retain her in her orbit. To do this, it was necessary to compare the space through THE BACONIAN PHILOSOPHY. 77 which heavy bodies fall in a given time to a given distance from the centre of the earth, viz : to its surface, with the space through which the moon, as it were, falls to the earth in the same time, while revolving in a circular orbit; for in all his reasonings, he supposed the planets to move in orbits per- fectly circular. At the time Newton made this calculation, he adopted the common es- timate of the diameter of the earth, as then used by geographers and navigators, which was erroneous. Therefore his conclusions were erroneous also. Some years afterwards, the discovery that a projectile would move in an elliptical orbit, when acted upon by a force varying in the inverse ratio of the square of the distance, led Newton to demonstrate that a planet acted upon by an attractive force varying inversely as the' square of the distance, will describe an elliptical orbit in one of whose foci the attractive force resides. But though Newton had thus established an hypothesis which explained the elliptical or- bits of the planets, and this hypothesis was founded upon an induction of facts made by THE BACONIAN PHILOSOPHY. Kepler*; and demonstrated by the application of 'mathematics by himself, yet an indis- pensable condition of the induction had not beenifujlfiled. He had not yet obtained any evidence that a force varying inversely as the square of the distance, did actually reside in the ? sun and planets; because his calculations for testing this, founded upon the comparison of the space through which heavy bodies fall in a second of time to a given distance from the centre of the earth, with the space through which= the. moon, as it were, falls to the earth, in a second of time while revolving in a circular orbit, assumed an erroneous es- timate of the diameter of the earth, as we have shown, and consequently did not test what it was intended to verify : but showed that the force which retains the moon in its orbit as deducted from the force which causes the fall of heavy bodies to the earth is, as one- sixth greater than that which is actually in- dicated in her circular orbit. But M. Picard having in 1679 executed the measurement of a degree of the meridian, Newton afterwards deduced from it the true diameter of the THE BACO.MA.V PHILOSOPHT. 79 earth, and trying his former calculation, he realized his expectations ; and found the force of gravity which regulates the fall of bodies at the earth's surface, when diminished as the square of the distance of the moon from the earth, to be nearly equal to the centrifugal force of the moon as deduced from her observed dis- tance and velocity ; and he thus fulfilled the fundamental condition of the inductive meth- od of investigation, of always ascribing a cause known to exist, to explain an effect. By this course of reasoning Newton connected the physics, of the earth with the physics of the heavens, and established the universality of the law of gravitation. What more delightful employment can the speculative philosopher have than the con- templation of the grand discoveries which we have been considering ! To one who loves truth for its own sake, and feels delight in the mere contemplation of harmonious and mutually dependent truths, the knowledge of such great truths is of sufficient value to re- pay him for the labour of discovery, even if they did not admit of any practical applica- 80 THE BACONIAN PHILOSOPHY. tion. To know what it is that paints the beautiful colours of the rainbow, and covers the hills and valleys in green, and gives the delicate tints to the flowers which picture the fields,; to know that the scathing lightnings which rush with such tremendous fury from the vast magazines of the heavens, is the same with the spark rubbed from the cat's back ; to know that the water which we drink and which appears so simple, is composed of two gases, one of which is more combustible than gunpowder, and produces instant death when inhaled, and the other is the supporter of combustion, though the two united is the chief agent by which we extinguish fire ; to know that the planets of such vast magni- tude, and moving with such velocity through such boundless space are held in their orbits by the same force which causes an apple to. fall to the ground ; to know the times of eclipses and the returns of comets dashing with a velocity quicker than thought over mil- lions of miles of space and returning with unerring certainty to the goal whence they set out : and all other wonders which natural THE BACONIAN PHILOSOPHY. 81 philosophy reveals, must forever, as mere matters of intellectual contemplation, be con- sidered as inestimable treasures. And the mere process of investigation according to the Baconian method, is one of the noblest and most delightful employments. The phi- losopher at almost every stage of his progress, is meeting with hints of greater things still undiscovered, which cheers the mind amidst its toil, with the hope of making still further progress ; and new fields of discovery are con- tinually opening in prospect and the light of his present discoveries throwing enough of their rays across the darkness before him, to reveal as much of other new truths as will stimulate him to continued exertion for their discovery : thus curiosity is ever kept alive, and exhausted energies renovated in the la- borious pursuits of knowledge. How utterly insignificant as mere matters of intellectual contemplation, is all the phys- ical philosophy of the ancients in compari- son with these magnificent discoveries in the different sciences ! And what can form a more striking contrast than the sublime argumenta- 82 THE BACONIAN PHILOSOPHY. tion of Newton and the petty sophistry of the philosophers of the middle age ! What are the eloquent reveries of Plato and the ingenious reasonings of Aristotle in comparison with the mighty mensuration by which Newton begin- ning with the dust on the balance measures the earthy and rising in the sublime argument, measures planet after planet and weighing them, balances one against the other, and not content with holding as it were, worlds in the hollow of his hand, he measures and weighs systems of worlds; and his mighty calculus still not exhausted, he balances systems of worlds against systems of worlds, and embra- ces in .-his argument the infinitude of the uni- verse, until the words of the sacred poet, " he weighed the mountains in the scales and the hills in a balance," intended to describe the, omnipotence of the deity, fall short in describing the power of one of his creatures. The wisdom of the Academy and the Ly- ceum have been overshadowed by the glory of Cambridge, and Greece yields to England in philosophical renown ! We see then, that as a mere matter of in- THE BACONIAN PHILOSOPHY. OO tellectual contemplation to satisfy the specu- lative mind, the Baconian philosophy is pre- eminently sublime. We will now show that it is also eminently practical ; and in this par* ticular, it differs from all the philosophies of the ancients., who thought that the only use of philosophy, was in its influence upon the mind in elevating it above the concerns of life, and thus purifying and preparing it for the philosophical beatitude of their heaven, into which none, but philosophers were to enter ; and that the practical affairs of life be- longed to those of common endowments who are fated by destiny to be mere " hewers of wood and drawers of water.' 5 But far differ- ent is the spirit of the Baconian philosophy. Humbling itself before Christianity, it ac- knowledges it to be a revelation from heaven, pointing out the same way to future bliss, for the peasant and the philosopher, and that it only , has the power "to deliver man from the bondage of corruption into the glorious lib- erty of the sons of God" ; and that though philosophy enlarges and elevates the mind and affords us unspeakable intellectual pleas- 84 THE BACONIAN PHILOSOPHY ure, yet that its chief office is to promote the general well-being of man in this life, by con- necting the sciences with the arts, and arm- ing them with a power which mere empiri- cism can never attain. It is then the great excellence of the Ba- conian philosophy, that even those of its dis- coveries which bave contributed most to the satisfaction of the speculative intellect and are apparently the most remote from every thing like practical application to the comforts of man, have frequently been applied to the most useful purposes of life. The discovery of the nature of light by Newton, at once led him to attempt a practical application of it ; and though nothing of importance result- ed from his labours, yet Hall and afterwards Dolland constructed achromatic telescopes, which could never have been done, if the fact of the different refrangibility of the different rays of light had not been known ; and this discovery, was thus applied to the arts in ac- cordance with the utilitarian spirit of the Ba- conian philosophy. Scarcely had Franklin discovered the nature of lightning, before he THE BACONIAN PHILOSOPHY. 85 constructed an apparatus to protect our build- ings on land and our ships on the sea from the ravages of the electric fluid; And thus by a discovery apparently so remote from all practical utility he disarmed the spirit of the storm of his thunders, and thereby showed to the world that knowledge is power. But the most fruitful practical applications have been made of Chemistry. It has been appli- ed to agriculture, to medicine, and to the mechanical arts. By applying the principles which we have exhibited, to the improve- ment of agriculture, it has made the most sterile waste so fertile, as to yield all the va- rious fruits of the earth in the richest abun- dance. Where not a blade of grass grew, now the most abundant harvests gladden the sight, as they spread out in ocean waves over the fields where chemistry has shed its fertil- izing dews. And by its magic power, chem- istry has released the various medical agents which lie embedded in the innumerable veg- etable and mineral products of nature, and handed them over to the healing art, to aid the vital powers in throwing off* from the 8 $6 THE BACONIAN PHILOSOPHY. body the many diseases which prey upon man. And its application to the mechanic arts, has bestowed the richest blessings upon man. Sir H. Davy applied its principles in the construction of the safety lamp ; by which man is enabled to walk with comparative safety in the bottoms of dark mines, with a light, amidst a gas more explosive than gun- powder, where, without this lamp, the miner is frequently exposed to as much danger as though he were walking in a magazine of powder with a lighted torch ; and thus thous- ands of lives and millions of money are saved by this one application of science to art. But the crowning invention of all, the one which constitutes the chief glory of science in its application to art, is the steam-engine. A profound chemical knowledge applied by the most exquisite mechanical skill, enabled James Watt to bring the steam-engine, which had been invented by Savery and Newco- men, to a degree of perfection which renders it the most valuable of all inventions of art. It brings under the control of man, an agent more potent than a hundred giants, swifter THE B AC ONI AN PHILOSOPHY. 87 than the Arabian horse, and capable of as- suming more forms in mechanism, than a Proteus, so as to apply itself to all kinds of work. It can pull a hundred wagons as easily as one — perform one kind of labour as easily as another. It is on the ocean, it is on the rivers, it is on the mountains, it is in the val- leys, it is at the bottom of mines, it is in the shops, it is every where at work. It propels the ship, it rows the boat, it cuts, it pumps^ it hammers, it cards, it spins, it weaves, it washes, it cooks, it prints, and releases man of nearly all bodily toil. This mighty agent is revolutionizing the world — annihilating time and space by its speed, and bringing the most remote parts of the earth together. And all this mighty power is gained hy a scientific knowledge of the nature of the at- mosphere which we breathe, and the water which we drink, and applying this knowledge to mechanism, so as to make these so familiar objects work for man. Here let us pause, and reflect upon the benefits conferred on England by the Bacon- ian philosophy. It has made her the great- 85 THE BACONIAN PHILOSOPHY. est nation in the world. It has done more to develop her wealthy than all the legislation of all the statesmen who have adorned her his- tory bj their financial skill. It has given her hundreds of bushels of wheat, thousands of yards of cloths, and bestowed innumerable comforts, where without its instrumentality, there would have been but one. It has en- abled her to extend her commerce over the whole earth, and bring into her treasury count- less millions of wealth. And this commerce is the source of her great power, both in war and peace, and is the means by which she is controling the destinies of the world. And though her whole policy is to extend her com- merce by cultivating the arts of peace, yet it is true, that she sometimes (and we abhor the wickedness of it) pushes her commerce by the thunders of her cannon into regions where ignorance forbids its entrance ; but the people who are thus treated, will in time learn, that it is equally for their benefit, with that of England, that her trade is extended to their shores, and they will feel that peace is the true policy of the world, and that all THE BACONIAN PHILOSOPHf. 89 men are mutually interested in each other's welfare and should live like members of one family. The commercial spirit of England is also the power which pioneers the way for the other great influences which she is exert- ing upon the civilization of the world. Her sciences, her arts and her literature are car- ried on the wings of her commerce over the whole earth. And the Christian religion is soon found smoothing the thorny pillow of the dying man, and pouring the balm of con- solation over his drooping spirit, in every clime where British commerce has placed her foot. But the Baconian philosophy is not confined to physical nature, as has been often asserted. It embraces all knowledge. Bacon express- ly says that his method of investigation is in- tended to be applied to all the sciences. "Some may raise this question (says he) rather than objection, whether we talk of perfecting natural philosophy alone according to our method, or the other sciences also, such as logic, ethics, politics. We certainly intend to comprehend them all. And as 8* $0 THE BACONIAN PHILOSOPHY common logic, which regulates matters by syllogisms, is applied not only to natural, but also to every other science, so our inductive method likewise comprehends them all." And in his Advancement of Learning, where he defines the boundaries of the different sciences, he has devoted as much attention to the intellectual and moral sciences as to the physical. But it is nevertheless true, that his labours were directed chiefly towards physi- cal science, because, in this, there was the greater necessity for exertion ; as it was prin- cipally through ignorance of this part of knowledge, that man was delayed in his career of civilization. And many, from the fact that Bacon has said so much about phys- ical nature, misconceiving the scope and spirit of his philosophy, have asserted that it is confined to sense, and is utilitarian, in the gross meaning of avarice, and that it necessa- rily leads to a selfish moral philosophy. It has happened to Bacon, as to other phi- losophers, who have originated a new move- ment of the human mind, that the errors of many of his successors who claimed, and THE BACONIAN PHILOSOrHT. 91 many who did not claim to be his disciples, have been charged to his philosophy, as its legitimate fruits. The doctrines of Hobbs, and Hume, and Hartly, and others in Eng- land, and of Condillac, and Helvetius, and D'Holbach and the host of infidels and athe- ists in France, have been again and again proclaimed as the legitimate and necessary deductions from the principles of the Bacon- ian philosophy The doctrines of the phi- losophers just mentioned, resulted from these philosophers seizing upon some one only of the great principles of the Baconian philoso- phy, and carrying it out to the wildest ex- tremes, without modifying it by the other principles of the system, and are, therefore, at most, nothing more than the errors which necessarily result in the development of the Baconian philosophy, and are not a part of that philosophy, but merely the exuviae thrown off from it as it passes through the process of development. Cicero, in his De Oratore, has remarked the very same thing of Socrates which we are now remarking of Bacon. " For, as they all," says he, " arose 92 THE BACONIAN PHILOSOPHY. from Socrates, whose discourses were so va- rious, different, and universally diffused, that each learned somewhat that was different from the other; hence families, as it were, of philosophers were propagated, widely dif- fering among themselves and vastly uncon- nected with, and unlike one another ; yet all of them affected to be called, and thought themselves the disciples of Socrates. For, in the first place, Aristotle and Xenocrates were the immediate scholars of Plato; the one of which was the founder of the Peripa- tetics, the other of the Academics. Then from Antisthenes, who admired chiefly the patience and abstemiousness of Socrates in his discourses, arose first the Cynics and then the Stoics. Next from Aristippus, who was charmed with the sensual part of Socrates' discourses, the sect of the Cyrenians flowed, whose doctrines, he and his successors main- tained without any disguise of sentiment. There were also other sects of philosophers, who generally professed themselves to be the followers of Socrates." We see then, that all the different sects of philosophers, who THE BACONIAN PHILOSOPHY. 93 succeeded Socrates, the morose and abstemi- ous Stoic, and the gay and voluptuous Cyren- ian, all claimed to be the true disciples of So- crates, and that Cicero says that their errors resulted from their seizing upon one princi- ple only of the philosophy of Socrates, and losing sight of the other principles. The Stoics seized upon patience and abstemious- ness, and the Cyrenians upon sensual enjoy- ments, both of which, when modified by the other, are correct principles, but when carri- ed to extremes, each is wrong, and will lead to false moral philosophy. Having thus indi- cated the source of the error which we are combating, we will now show that it is an error. The position that the Baconian philosophy leads to a selfish morality, is maintained by many on the ground that the Baconian phi- losophy admits but one source of ideas, viz : sensation. The argument is, that within the sphere of sensation, there is no idea of right and wrong — that pleasure and pain are the only ideas furnished by sensation to denote the moral qualities of human actions, and that we approve of some acts, because they 94 THE BACONIAN PHILOSOPHY. give pleasure, and disapprove of others, be- cause they give pain ; and that, therefore, according to this theory of mind, utility is virtue, and self-interest the ground of moral obligation. But we shall show in the second chapter of the second part of this discourse that the Baconian philosophy admits two sour- ces of ideas, viz : sensation and conscious- ness : and therefore this argument falls to the ground ; because the ideas of right and wrong are developed in consciousness, and it is in consciousness, that the Baconian philosophy lays the foundation of morality, and not in sensation. According to the Baconian philosophy, we must examine all the facts of man's moral constitution, and establish the fundamental truths of moral philosophy by psychological observation. Rejecting all innate moral prin- ciples or notions, it appeals to experience, to both the light of nature and revelation. It therefore leaves man perfectly free to exam- ine all the facts of his moral constitution, and to establish whatever system of morals, a sound induction may warrant, whether the THE BACONIAN PHILOSOPHY. 95 selfish or the disinterested system. When then we look into the heart of man, we there find certain instinctive affections, such as love, hope, fear, anger, pity and many others which are all certainly disinterested in their nature; as they seek their respective objects, by natu- ral impulse or sympathy, without the mind's thinking of anything beyond, whether their satisfaction or disappointment will be agreea- ble or disagreeable. We also find in the mind, the power to distinguish moral good and evil. It is upon these attributes of our spiritual nature, that the Baconian philosophy founds morality. But let us inquire into these facts further, and ascertain the relation in which the affections stand, to the power in the mind to distinguish good and evil, or in other words, ascertain the connection between the feelings and the intellect. If a beautiful object be presented to the mind either through sense, memory or ima- gination, and occupies its attention exclusive- ly, the emotion of love, is by a great psycho- logical law, necessarily excited in the mind, and will continue until the object is removed. 96 THE BACONIAN PHILOSOPHY. or forgotten, or some other object is present- ed in its stead. For it is a law of our mental constitution, that every emotion whether of love or hatred is allied to some object of per- ception or memory or imagination, and is de- pendent upon it, as its antecedent or cause, and the emotion can never be excited in the mind except by its appropriate object being in the view of the mind, and never can cease to exist in the mind until the object is forgot- ten or removed from its view. Just as the mind sees so the heart feels. It is thus manifest that considerations of self have no agency in producing our emotions whether of love or resentment, in the natural operations of the mind, and consequently the great law of the affections on which morality is based, is dis- interested, — operates uninfluenced by consid- erations of self. But this connection between the perceptions and the affections shows that the correctness of our moral philosophy will depend upon the enlightenment of our intel- lect and the purity of our affections. That goodness is goodness is hard to be perceived by the greatest minds, if the moral feelings THE BACONIAN PHILOSOPHY. 97 are corrupt. This is a truth written in blood upon the pages of history. But whenever the mind perceives goodness or moral beauty, the heart is necessitated by the great law of the affections just indicated, to feel the emo- tion proper to it, of love, and when it sees vice or moral ugliness, to feel the emotion proper to it, of aversion, and this without any consideration of self mingled in it. We see then by this analytical induction, that the prin- ciple of morality is disinterested; because the Creator by the great law of the affections has made it imperative on us to love virtue for its own nature, having made it natural for the mind to love virtue and hate vice by creating the relations of love and hatred between them. But as man is not under a law of ne- cessity like mere brute matter and incapable of change, the obliquity of his mind may become such as to render him unable to see the loveliness of virtue, which is the same as not seeing virtue at all, for loveliness is its very essence, just as the eye may be so dis- eased, as in jaundice, as to render him unable to see the real colours of objects, and the 98 THE BACONIAN PHILOSOPHY. sinfulness of his own heart will cast its hue over virtue ; just as the jaundice of the eye will cast its hue over the objects of vision, and neither the loveliness of the one nor the colours of the other can be perceived. The truth is, the perception and the emotion con- stitute the state the mind is in, when any object is present in thought, and they cannot be separated. They are not distinct acts of the mind, but are elements which make up the act of apprehension or spiritual discern- ment. And it was from the fact, that Helve- tius did not discern the truth, that perception and emotion are both elements of spiritual discernment, and dwelt too exclusively upon the phenomena of emotion,, that he fell into the error that all mental acts are nothing but feeling — that to think and to judge are but to feel ; and that Diderot in criticising this obvious error of Helvetius fell into the oppo- site one, and maintained in his essay on the origin and nature of the beautiful, that the perception of beauty by the mind is a matter of reason alone, like the perception of the truth that two and two make four. We see THE BACONIAN PHILOSOPHY. 99 then, that according to the phsychological facts which the Baconian philosophy points out as the foundation of morality, that its principle is disinterested. Man does certain- ly feel the moral Tightness of truth and justice, without any view at the time to their consequences, just as he feels an appetite for food without any view to its utility upon the animal economy — the one feeling terminates on virtue for its own sake and the other on food for its own sake. But God in his great benevolence has so organized the system of things, as to make that which is right, useful in such a vast majority of instances, as to induce us in cases where it is doubtful what is right, to use the relative utilities of the acts as the standard of their rightness, and it has indeed induced some to maintain that utility is the essence of right. But some contend that the Baconian phi- losophy leads to a selfish morality, in a differ- ent mode from that which we have just ex- amined. That it tends to corrupt the moral feelings by infusing into them, the spirit of selfishness, in directing so much inquiry into 100 THE BACONIAN PHILOSOPHY. the developement of the resources of physical nature ; and thus making man to think con- tinually about his physical comforts, and to place too much value upon the riches of this world. That the Baconian philosophy has done more than all other philosophies put together, to develop the resources of physical nature, and thereby to multiply the physical comforts of man, we have already shown ; and so far from shunning this result, or wishing to conceal it, it has been the main purpose of this part of our discourse, to ex- hibit the fact in all its amplitude, and to pro- claim it as the chief glory of the philosophy which we expound. If such a result makes man selfish, then is the destitution of barbar- ism, better fitted to produce a sound morality than the wealth of civilization. Then is man, clothed in skins, possessed of more generous sympathies, than when clothed in the comfort- able fabrics of cultivated art; and his heart contracts to a narrower selfishness, when he accumulates wealth by millions, than when he saves it by mites. If these be true proposi- tions, then, have we entirely misread human THE BACONIAN PHILOSOPHY. 101 history. The fallacy of these conclusions, shows the falsity of the premises from which they are deduced. And it is evident, that the whole tendency of the Baconian philoso- phy is to elevate the condition of man. It enables him to supply his physical wants hy a small portion of labour, and to devote his consequent leisure to the cultivation of science and art. And it dignifies and ennobles the employments which are devoted to the promo- tion of our physical comforts, by connecting them with the sciences. Under its influence, mechanics are no longer mere handicrafts- men, but are men of science, possessed of en- larged views of human advancement. Watt and Fulton occupy the highest places amongst the benefactors of mankind ; and are quite as fit to join that divine assembly of spirits, where Cicero in his De Senectute, rejoices that he shall meet Cato, as either of those sages of antiquity. But let us throw aside all speculation, and look to facts. Where is the nation that can boast a literature pervaded by a loftier moral- ity than England ? It is true that some of 9* 102 THE BACONIAN PHILOSOPHY, her writers maintain the selfish system of morals, and some the disinterested. But this has been the case at every era of philosophi- cal developement, in every nation of the civ- ilized world. In morals, as in every thing else, men often bewilder themselves in the minuteness of analysis. Those who main- tain the system of disinterested morals differ as to the basis of morals. One class refer- ring our moral ideas to a special faculty, termed the moral sense, others to reason, and others to both the reason and the sensibility. And those also who maintain the selfish system differ widely, as to the basis of their principle. This is inseparable from the nature of the subject, for it is not purely a philosoph- ical subject : but derives more of its light from revelation than from nature ; and there- fore, in attempting to ascertain the philosoph- ical foundation of moral obligation, we shall often find our line too short to reach the bottom. The difficulties are inherent in the subject; and they have been more nearly overcome by the English than any other people. And not only is the literature which THE BACONIAN PHILOSOPHY. 103 has grown up under the influence of the Ba- conian philosophy pervaded by a lofty moral- ity, but the people who have drunk most co- piously at its fountains, and whose mental habits and moral principles have been formed under its influence, are distinguished by their disinterested benevolence. They dispense millions annually in charities at home ; and their benevolent societies are healing the sick, clothing the naked, and feeding the hungry, and instructing the ignorant in every clime of the earth. In examining this question, we must dis- tinguish the commercial spirit of England, from the spirit of philanthropy. While the first toils by day and by night to accumulate wealth, the latter toils by day and by night to expend it in alleviating the sufferings of the af- flicted of all nations, and kindreds and tongues. How superficial and ignorant then, is the opinion so often expressed, that the Baconian philosophy leads to a selfish morality ! We have shown the contrary, both by philosophi- cal analysis and historical fact, which are the 104 THE BACONIAN PHILOSOPHY only two modes of proof of which the sub- ject is susceptible. The same class of thinkers who maintain that the Baconian philosophy is purely sensu- al a mere pander to our animal comforts, maintain also, that it has no ideal, and is utter- ly inconsistent with all the arts of beauty. That its main object is to make money plenty in men's pockets; and that the spirit and style of its kindred poetry is exemplified in the following couplet : " A penny sav'd is two-pence clear,, A pin a day Va groat a year." Let us examine the truth of this charge. The Baconian philosophy, as we shall show in the second chapter of the second part of this discourse recognises consciousness as fully as it does sensation, as a source of ideas, and consequently just as fully embraces with- in its "scope, the world of mind with all its subjective realities, as it does the world of matter with all its objective realities. It takes therefore in its view, all the phenomena of the spiritual world, as well as of the material, and all the adaptations between these differ- THK BACONIAX PHILOSOI'H V. 105 ent worlds, from which the sublime and beau- tiful in art, can be educed. And it teaches a grander and a nobler, because a truer style of literature, than any philosophy which has been the source of culture to any people known in history. It takes nature for its model — the archetype which God has made — and repudiates all that is speculative in taste, as it does all that is speculative in reasoning. And the true theory , of taste, is to imitate na- ture, not it is true, by a servile copy, but by exalting her — by making her beauty more beautiful, and her sublimity more sublime — but still by letting the beauty and sublimity, be the beauty and sublimity of nature, merely exalted. For the human heart was formed to suit the natural, and the natural was form- ed to suit the human heart, to call forth all its powers. Some things, by a great pathological law are agreeable to the human heart, and others, disagreeable. Some things naturally excite the feelings of sublimity, and others the feelings of beauty. These things are formed respectively by the Creator for the very pur- pose. It is an adaptation cf the external 106 THE BACONIAN PHILOSOPHY. world ; to the spiritual constitution of man. The province then, of the science of taste, is to ascertain, what those things are, and the distinguishing property which constitutes them, in both the material and spirtual worlds, which naturally, and of their own original adaptation, excite the emotion of the beauti- ful or the sublime, or any other emotion, which it is the* object of art to call forth. For some things will excite these emotions by association, and not of their own nature ; and consequently are not so well calculated to produce these emotions, as the things from which they have derived this power by asso- ciation ; and in fact cannot excite these emo- tions at all, in minds in which, they have not been asssociated, with the things from which they have derived this adventitious power. Truth or conformity to nature, then, is the great standard of taste. For there is a true in taste, a true in morals, as well as a true in matter ; and all of them are to be ascertained by inductive observation, and not by specula- tive conjecture. Surely then, the literature which springs up as an offshoot of that phi- THE BACOMAN PHILOSOPHY. 107 losophy which directs all our observations to nature, and admits no criterions whether in science or art, but the natural, is most like- ly to approach nearest to nature in its repre- sentations of the sublime and the beautiful and all that affects the human heart. And did the speculations of the philosophers of ancient times and of the middle age, ever present such sublime and such beautiful visions before the fancy, as the Baconian philosophy has spread out in the vast perspective of mod- ern discoveries ? The truth is, the views of nature as presented in these discoveries have a grace and a grandeur, a beauty and a sublimi- ty far above all the visions of fancy that ever lay in the enchanting walks of speculation or poetry. Induction has in fact evolved higher standards of sublimity and beauty, than ima- gination ever bodied forth in its most raptur- ous visions of the ideal. How then, can the Baconian philosophy lead to a mean literature, when it familiarizes the mind to the most sub- lime and beautiful objects of contemplation ? It must have the opposite effect. It must give a loftier ideal to the orator and the poet 108 THE BACONIAN PHILOSOPHY. than the mere speculative philosophies ever furnished. And no writer has presented a more exalted estimate of poetry, and deline- ated its high behests with more accuracy than Bacon himself. "The use of poesy (says he in the Advancement of Learning) hath been to give some shadow of satisfaction to the mind of man in those points wherein the nature of things doth deny it ; the world being in proportion inferior to the soul; by reason whereof there is agreeable to the spirit of man a more ample greatness, a more exact goodness, and a more absolute variety than can be found in the nature of things. There- fore, because the acts or events of true histo- ry have not that magnitude which satisfieth the mind of man, poesy feigneth acts and events greater and more heroical : because true history propoundeth the successes and issues of actions not so agreeable to the merits of virtue and vice, therefore poesy feigns them more just in retribution, and more ac- cording to revealed providence : because true history representeth actions and events more ordinary and less interchanged, therefore Y'HR BACONIAN PHILOSOPHY. 109 poesy endueth them with more rareness and more unexpected and alternative variations : so as it appeareth that poesy serveth and conferreth to magnanimity, morality and delectation. And therefore it was ever- thought to have some participation of divine- ness, because it doth raise and erect the mind by submitting .the shows of things to the de- sires of the mind \ whereas reason doth buc- kle and bow the mind unto the nature of things." This admirable delineation of the objects and nature of poetry, sounds doubt- less, in the ears of those whose opinions we are examining, more like the language of Homer or Dante or Milton discanting on his divine art, than like the language of the father of the experimental philosophy. The truth is, the mighty and various and finely-fashioned mind of Bacon is as little understood by this class of thinkers as the spirit and scope of his philosophy. His mind was a mirror held up to nature, which reflected it, in all its vast- ness and all its minuteness, all its sublimity and all its beauty : revealing as much from the spir- itual world as from the material — from the 10 110 THE BACONIAN PHILOSOPHY dark abysses of the human heart, as from the hidden depths of matter. The chief ground, on which, the opinion that the Baconian philosophy leads to a mean literature, appears to rest, as far as any thing definite can be gathered from the loose and vague generality of the language in which it is usually expressed, is that this philosophy directs the mind so exclusively to considera- tions of utility, that it renders it incapable of appreciating the beautifuh This is a singu- larly erroneous view of the matter. For it is not immediate considerations of utility which prompt the Baconian philosopher to his in- quiries. But it is the love of truth — the de- light of viewing new truths evolved in ever varying forms of beauty from the multifarious facts which beset the path of investigation — the felt triumph of the march over the difficul- ties of science, as the enquirer steps from alti- tude to altitude on the before untrodden steeps of investigation, until he reaches a summit, from whence he can descry the goodly classi- fications and the harmonies of principle evolv- ing themselves from the chaos of facts which THE BACOx\IAN PHILOSOPHY. Ill lie spread out in such boundless profusion over the vast regions of the universe. These are the considerations which prompt the Ba- conian philosopher to his inquiries. And af- ter he has discovered some new principle, then it is, that in accordance with the spirit of his philosophy, he enters upon considera- tions of utility in its applications to the relief of human wants. The Baconian philosophy, though considerations of utility embrace so much of its aim, and constitute so much of its glory, does not reject the beautiful, but embraces both it and the useful in perfect harmony, within the universality of its doc- trines. And though the physical sciences to which this philosophy has directed so much attention, are emphatically the sciences of utility, still their study, as the opinion which we are examining presupposes, does not ne- cessarily lead the mind off from the study of the beautiful, or blunt its relish for objects of taste. The relation between the different branches of knowledge is much more inti- mate than this supposition assumes. Such is this intimacy, that the physical science, which 112 THE EACONIAN PHILOSOPHY. of all others, appears to the superficial obser- ver, to be the most remote from any affinity to the arts of beauty, has been applied to two of these arts with the most felicitous success. Sir Charles Bell has applied his discoveries in the nervous system to the arts of painting and sculpture. Having discovered that, be- sides the two great systems of nerves of sen- sation and motion, other nerves went to the muscles and moved them, and that these arose from a tract of the spine separate from either of the two columns originating the other nerves, and that they went chiefly to those muscles which subserve the purposes of respiration ; and that as the function of respi- ration in man was not designed for the sole purpose of vitalizing the blood in the lungs, but also, for communicating the thoughts and passions of his soul, he had the genius to per- ceive, that the nerves regulating respiration, must be the nerves of expression and emotion. He therefore under the impluse of a most ex- alted genius for the arts of beauty, developed this grand idea, and wrote his celebrated work, the " Philosophy of Expression, " and THE BACONIAN PHILOSOPHY. 113 in this way applied his discovery of the nerves of respiration to teaching the painter and the sculptor, a knowledge by which he may imitate and understand and correctly depict the evervarying play of human passion. And thus a man who spent his life in dissect- ing the bodies of his fellow men and of the in- ferior animals, could pass out of this butcherly employment, as those whose opinions we are examining would esteem it, and teach us how to breathe life and feeling into the canvass and the marble. And Bell himself was one of the finest painters of his day — was no less skilful with the pencil of the painter, than with the knife of the Surgeon. Though, af- ter the battle of Waterloo, he went to the scene of slaughter and spent days and nights amidst the dead and dying, sleeping only one hour and a half out of the twenty four, for the purpose of perfecting himself in military surg- ery, yet at a later period of his life, we find him making a pilgrimage to Rome, to view in that imperial city the noble remains of ancient art, to enable him to put the finishing touch upon his "Philosophy of Expression." See then! 10* 11-1 THE BACONIAN PHILOSOPHY. how extraordinary and mysterious, is the con- nection between utility and beauty, between the anatomy of the nervous system and the arts oi painting and sculpture. The same discoveries are applied to the arts of utility and to the arts of beauty, to medicine and to painting and sculpture. But let us illustrate this point a little fur- ther. Geometricians have discovered what is the curve of the greatest resistance or so- lidity, and have thus established a fact of the greatest utility in architecture. Michael An- gelo in forming the model of the dome of St. Peter's at Rome, gave it that oval or curve which appeared to his judgment as an artist, to be the most beautiful as drawn on the giv- en breadth and height. And such is the ex- quisite beauty of the dome that it fills every beholder with admiration. It is said, that the distinguished geometrician M. de la Hire being at Rome, was so struck by the elegance of this structure, that he determined to in- quire into the rationale of its impression on the mind ; and on examining the geometrical properties of the curve of its outline, he found THE BACONIAN PHILOSOPHY. 115 that it was that of the greatest resistance or solidity. And thus it is ascertained, that in this instance, what is the most solid or useful in art is also the most beautiful. And what an extraordinary proof does it furnish of the sublimity of the genius of Michael Angelo for the beautiful in art, that in his attempts to sketch the oval outline of the greatest beauty for the dome, he should by the mere exercise of his judgement as an artist, have hit upon the exact curve with mathematical precision. For the identity of the curve of the greatest beauty with that of the greatest utility could never have been ascertained, except by some sublime genius in the felicity of his judg- ment, ascertaining the first, as it were, by an inspired intuition, and then the geometrician, by the unerring calculus of his science, dis- covering that what the artist has thus con- ceived to be the most beautiful oval outline, is the exact mathematical curve of the great- est resistance. And this, upon the doctrine of probabilities, amounts almost to a demon- stration, that the curves of utility and beauty are the same. 3 16 THE BACONIAN PHILOSOPHY. But the fact, that utility and beauty are of a very kindred nature, or rather, that the first is often an important ingredient of the last, does not need further illustration. For so frequently are they found conjoined both in art and nature, that some philosophers, though very erroneously, have been led to insist, that utility is the essence of beauty — that beauty consists in the fitness of things or the adaptation of parts ; just as some philoso- phers have been led by a like partial view, to insist that utility is the essence of moral good, from the frequency of the union of the expedient and the right in the moral economy of the world. We can now, from the altitude to which our analysis has carried us take a wide sur- vey of the topic which we are discussing, and see by the light of science, how ignorant and grovelling is that view of the Baconian philosophy, which sees in its vast range noth- ing but a sordid utility, while, that utility which is consistent with all that is noble in morality and sublime and beautiful in art, is the doctrine which it teaches from the first THE DACOMAN PHILOSOPHY. 117 aphorism in the Novum Organon, to the end of its last lesson. But it is useless to dwell longer upon phil- osophical analysis, when we have historical proof that the Baconian philosophy is consist- ent with the arts of beauty, in the noble pro- ductions of English literature ; for the liter- ature of every nation partakes of the nature of its philosophy, as the very charge which we are considering assumes. Where then is there a nobler literature, than that which has been cultivated in the same soil and by the same people, with the Baconian philosophy ? Shakspeare, who was the cotemporary and friend of Bacon, and whose productions are so signally marked with the common rsense which, arising in the Baconian philosophy, pervades the whole of English civilization, stands at the head of the dramatic writers of the world. As though he had borrowed the magic wand of nature herself, he creates all beings with the same ease that she does, and .fixes them in their appropriate employments, and plans and executes their different offices, with an exactitude which shows that every 118 THE BACONIAN' PHILOSOPHY. act proceeds, from its natural motive, and every destiny from a plan of coincidents in exact conformity to the dispensations of Prov- idence. The most dreadful passions are managed with as easy a conformity to nature, as the most gentle. Murder, with its ferocity and its relenting, its determination and its hes- itancy, before it reddens its hands in blood, and its remorse, and its imaginative agony, after it has done the dark deed, is dramatized with as much perfection as if the poet had seen with his eye the naked heart of the mur- derer throbbing in guilt. And with equal ease, true love is presented in all its artless- ness, whispering its affection in words as soft and simple and sweet, as the attic bee ever distilled upon the lips of a Grecian shepherd- ess; or else, sitting silent, under the restrain- ing diffidence of a pure heart, " until conceal- ment, like a worm in the bud, feeds upon her damask cheek. 5 ' — And jealousy, that monster of suspicion, to whom, " trifles light as air, are confirmation strong as proofs of holy writ, " is presented in all his odiousness. And avarice standing by his bond, and humor THE BACONIAN PHILOSOPHY. 119 holding both his sides, and every human pas- sion are presented in ideal perfection. The dark, and awful, and mysterious abyss of the human heart is completely fathomed and the poet sees by the light of Christianity, how, fearfully and wonderfully it is made, and paints it, as with a pencil dipped in inspira- tion. And though Greece had her Homer, England has her Milton ; and never since the angels' harps, which hailed the morn of the creation, has a nobler been strung than his. The angels sang the joys of life, Milton the woes of death. And did a deeper melo- dy, and fuller of the dirgelike sounds of woe, ever flow from the versification of poetry ? Was the great epic of eternal death in all its horrors, ever before made a reality to the living ? Catching the sublime pathos of the old poets of Judea, and the fire and finish and copiousness of Greece, and transforming and subordinating all to the type of his own mighty genius, he has made a poem worthy of the great theme of the fall of man. The contrast between paradisaical innocence and happiness and infernal wickedness and mise- 120 THE BACO.V1AN PHILOSOPHY. ry is presented in terrific reality. Such is the grace and beauty and loveliness of the first woman as she appears to the creative fancy of the poet, that he represents Satan, though with a bosom filled with the malice of hell, and intent upon the destruction of man, merely because man was innocent and happy. as captivated for a moment by her charms as he beheld her alone, amidst the rich shrubbery of Eden, enchanting the scene of bliss she moved in. But this exquisite sympathy of the poet for true loveliness, does not, for one moment, lead his judgement astray, so as to make him soften the character of Satan. For the unconquerable malignity and insatiable hate of the arch fiend, is depicted in all its dreadful deformity ; and the horrors of hell are seen amidst the " darkness visible,' 7 in such horrifying import as to show that ei there. hope never comes, that comes to all." The poet is always master of himself; is never overpowered by the sublimity, nor enchained by the beauty of his conceptions : but with the self-possession of a great artist, he sets forth every thing in its proper position, and THE BACONIAN PHILOSOPHY. 121 in its proper character, and in language so ex- pressive and so suited to every topic, as to place him perhaps at the very head of the great masters of diction. And Butler, in his Hudibras, has given to the world, the great epic of ridicule. With a fancy alive to the ludicrous, he has caught its minutest shades in every action of life, and presented them in an epic poem ; and thereby the majestic epic be- comes ludicrous. The conceptions of the poem are ludicrous, the language is ludicrous, and even the very rhymes. The poet, it is true, shoots keen shafts at his fellow-men, but they are dipped in the unction of good-na- ture, and not in the venom of malice. Such a poem furnishes entertainment to one of the most important faculties of the human soul, the sense of the ludicrous — which ministers so much to the smiles of home, the gaieties of companionship, and by its goodly influ- ences so often sweetens the sourness of our feelings amidst the annoyances and the ills of life, and opens the heart to the frailties of hu- man kind, and makes us sympathize with the whole race, rich and poor, learned and ignor- 11 122 THE BACONIAN PHILOSOPHY. ant, as we see their extravagances through the amiable medium of a laughing heart — -'■ and is therefore worthy of a place amongst the great works of art. And Robert Burns, with his harp tuned, now to merry, and now to sorrowful music, is heard amidst the choir of English poetry, reviving by his natural strains, the youthful freshness of human feel- ing, and keeping in harmony, those delicately tuned chords of the heart, which in the trials of life are so apt to loose the sweetness of their primitive melody. But, we will not particu- larize further ; for the English muse has sung of every theme in original strains ; and has al- so proved the beauty, and strength, and co- piousness and flexibility of the English lan- guage by translating into it the master-pieces of antiquity, and showed that the streams are almost as pure in these channels, as in their Grecian and Roman fountains, The prose literature of England also, is rich in its abundance of matter and excellence of style and the wide range of its topics. Her historians are superior to any of modern times, and perhaps equal to those of ancient THE BACONIAN THILOSOPHY. 123 Her orators, as suited to the sphere of modern civilization, are equal to any, in any period of human history. In profound views of human nature, in far insight into the policy of legis- lation, and in all the knowledge of statesman- ship, English oratory is far before that of an- tiquity. And in the mere art, English orato- ry is not easily surpassed. In the choice of those topics, both local and general, which lead the intellect and the heart captive ; and in the easy and shining fluency of narrative, the sparkling ripples of wit, the bold, and headlong and dashing cataracts of declama- tion, and the full and swelling, and sweeping and overwhelming tide of argument, and the lightning's flash of suddenly provoked invec- tive which illuminates the whole flood of speech, and falls mercilessly upon its victim, it may well compare with that of any nation ancient or modern. In criticism also, wheth- er exegetical or purely rhetorical, English literature is highly distinguished. And as a specimen of historical criticism, there is noth- ing so ingenious, so original, so masterly, so triumphant and so to be marvelled at, as Pa- 124 THE BACONIAN PHILOSOPHY. ley's " Horae Paulinae, " It is a wonder of ingenuity — a miracle of logical acumen. Facts in the epistles of Paul, which separately send forth a mere glimmer of light, and which are apparently so unconnected as never to be at all associated in thought, by even careful readers, are selected and brought together in logical order, and the feeble lights of each are so concentrated upon the fact sought after, and the fact is so illuminated in every point, that you can no more doubt of its truth, than you can of the reality of day, when the sun ascends the meridian. In prose fiction too, what literature can compare with the English ? Where else, can so unique a group of such masterly productions of their kind be found, as the Pilgrim's Progress of Bunyan, the Robinson Crusoe of De Foe, the Gulliv- er's Travels of Swift, and the Tristram Shan- dy of Sterne ? And how many thousands of all cultivated nations, have been charmed by the magic writings of Walter Scott ! The young and the old, the learned and the ignor- ant, the wicked and the pious, have all been carried along on the enchanting tide of his THE BACONIAN PHILOSOPHY. 125 narrative as it flowed from its exhaustless fountain, through the ever-varying scenes of an epitomized world, and all have been equal- ly delighted with the wonderful exhibition. Such then, is the literature, laden with so many masculine beauties, which has been cul- tivated in the same soil and by the same peo- ple, with the Baconian philosophy. How erroneous then is the opinion, that the Bacon- ian philosophy has no ideal, but is confined to sense, and leads to a mean literature. While answering the charge just consider- ed, we have admitted that the literature of every nation or epoch partakes of the nature of the philosophy of that nation or epoch; because it is a well-established historical fact, and is in truth, nothing more than the exhi- bition, by a people, of the same bent of mind in literature and philosophy. The common sense of the Baconian philosophy is manifest- ed throughout every department of English literature. The characters in Shakspeare's plays are not mere personified qualities like the persons in an allegory : but are real men and women, such as we meet with in the 11* 126 THE BACONIAN PHILOSOPHY. world ; actuated by the same diversity of mo- tives and seeing the same objects. The particular passion sought to be delineated is individualized in some person, and the excel- lence of the delineation consists in the har- mony between the passion though exhibited in all its ideal exaltation, and the character in which it is set forth. For example, murder, and avarice, and jealousy and humor are not exhibited each in some metaphysical creature, which has no other passion than the one ex- emplified, but in real characters, which can sympathize with the circumstances of real life, and are at times under the influence of all the other passions of man, as different sit- uations call them forth. Murder is exhib- ited in Macbeth, avarice in Shylock, jealousy in Othello and humour in Falstaff, who are all men full of the common sympathies of humanity. This is the greatest triumph of the dramatic art, to invest the ideal with hu- manity. It is true that Shakspeare also cre- ated such characters as Calaban ; but this was merely a wayward freak of his genius. And the same characteristic is exhibited in the THE BACONIAN PHILOSOPHY. 127 writings of Milton. His fiends and angels are not metaphysical abstractions ; but are men exalted into superhuman greatness. Though Satan does not appear " less than archangel ruined," still he appears like a wicked man of superhuman powers. And the angels appear such as we may imagine good men may become in a world where all their powers are exalted. This likening of spirits to men, we are well aware has been censured by some critics as a great impro- priety, and the Mephistophiles of Goethe, which is a metaphysical incarnation of sin, has been reckoned a finer delineation of the spirit of wickedness than the Satan of Mil- ton. But this criticism, we apprehend, is founded in a misconception of the nature of the poetic art, whose province it is to seize upon practical criterions, and not upon spec- ulative — to deal with realities, and such things as can be made so much like realities, as to awaken the common sympathies of the human heart, and not with metaphysical ab^- stractions — to be like Shakspeare, and no,t like Goethe, like Robert Burns, and not like 128 THE BACONIAN PHILOSOPHY. Coleridge. But be this as it may, Milton has certainly taken a common sense view, and not a metaphysical one, of his great theme, and thereby showed the national trait of his mind. And Butler has taken a common sense view of human nature in his great poem. Hudibras, with all his ludicrous fa- naticism and solemn folly, is still a man ; and so of every other character. And as to the poetry of Burns, it expresses more of natu- ral feeling, such feeling as all men have, than that of any poet known to history. But it is useless to dwell upon this topic; for all the late writers upon the history of literature on the continent of Europe, have made special reference to the fact that English literature is pervaded by a vein of common sense. The English have even examined the evidences of Christianity according to the principles of the inductive method, or of common sense. Butler in his analogy, has drawn conclusions as to the truth of Christianity from the anal- ogy which exists between it and the course of Providence as exhibited in nature; which THE BACONIAN PHILOSOPHY. 129 •is as strictly an inductive process, as any used in the investigations of natural philosophy. But there is a still graver charge brought against the Baconian philosophy. It is said to lead to materialism and atheism. DeMa- istre, in his commentary on the philosophy of Bacon, says : " Every line of Bacon con- ducts to materialism : but in no part has he shown himself a more skilful sophist, a more refined, profound and dangerous hypocrite, than in what he has written on the soul." And Schlegel, in his history of literature, says : " The philosophy of sensation which was unconsciously bequeathed to the world by Bacon, and reduced to the shape of a regu- lar system by Locke, first displayed in France, the true immorality and destructiveness of which it is the parent, and assumed the ap- pearance of a perfect sect of atheism." In the second chapter of the second part of this discourse, it will be shown, that the Baconian philosophy recognises the testimony of con- sciousness, as fully as it does that of sensa- tion. If this be so, how can that philosophy lead to materialism ? Consciousness tells us 130 THE BACONIAN PKIL030PHY that the soul is not material ; for we are cer- tainly conscious that its attributes are not those of matter. Sensation informs us of the ma- terial world; consciousness of the spiritual world ; and we have no right; according to any, rule of evidence or logic ; to predicate in the way of philosophical affirmation; any idea derived from the material world; of the ob- jects of the spiritual world ; because the ideas of the qualities or attributes of spirit; we get from consciousness; and we cannot pre- dicate of spirit; any quality but what is ascer- tained by consciousness; and neither can we predicate of matter; any quality but what is ascertained by sensation. We have no evi- dence therefore; that the soul is material ; because the knowledge of its nature is de- rived from a source; from which not one idea appertaining to matter is derived. The Ba- conian philosophy; therefore; admits the same amount of evidence in favour of the immate- riality of the soul; that the a priori philosophy does; and therefore rests upon the same foundation in this particular. And so far from the Baconian philosophy T1TE EACONIAN PHILOSOPHY. 131 being atheistical, Bacon has defined the boun- daries, and pointed out the nature of the ev- idence upon which natural theology rests upon the principles of his philosophy, with admirable precision, as will be shown in the third part of this discourse. And no nation has cultivated natural theology with such as- siduity and success, as the English. The more the Baconian philosophy has been culti- vated, the more has natural theology advanc- ed. It is in fact the boast of this philos- ophy, that it has revived the study of natural theology, after it had been abandoned and scouted by the philosophers of the continent of Europe, as an unprofitable study. "It gave a particular pleasure to Sir Isaac New- ton," (says Maclaurin in his account of the writings of Newton,) "to see that his philo- sophy had contributed to promote an atten- tion to final causes, as I have heard him observe, after Des Cartes and others had en- deavoured to banish them." And where is the great work of Paley ? the two first chap- ters of which approach as near to the certain- ty of mathematical demonstration, as it is pos- 132 THE BACONIAN PHILOSOPHY. sible for moral reasonings to do. The eviden- ces of natural theology pass through the achro- matic mind of the author, without being dis- coloured by prejudice or passion, and paint upon his pages, their doctrines with all the life and precision of daguerreotype. And yet there never was a mind more thoroughly imbued by the philosophy of sensation, as Schlegel xalls it than Paley's. And the Bridgewater treatises have brought all the discoveries of the Baconian philosophy to prove and illustrate natural theology. And Bishop Butler even in his day, considered natural theology as so well established in English philosophy, that he assumed its truth as the foundation of his great work on the analogy between natural and revealed reli- gion. So we see that in English philosophy, revelation, natural theology and physical sci- ence, are united in perfect harmony, pro- claiming with one voice that there is a God. Such then is the character of the Baconian or English philosophy : it embraces every thing that is sublime in speculation, useful in practice, lofty in morality, beautiful in art, and; reverential in religion. THE BACONIAN PHILOSOPHY. 133 We now feel ourselves free to declare, that Bacon has done more to advance the progress of the human mind than any uninspired man known to history. There are no writings in the whole of literature, which take so pro- found a view of human nature, and point out so exalted a destiny for man, as his. With a philosophical forecast unparalleled in the world, he has given anticipations of some of the greatest discoveries of modern science. Even the law of gravity is conjectured, and its application to the explication of the tides of the ocean is distinctly stated. And his philosophy possesses within itself the princi- ple of perpetual progress ; for, it is not like the ancient philosophies, confined to specula- tive principles, from which an explanation of all things is to be deduced, and as these prin- ciples are in time found to be incapable of ex- plaining the phenomena of nature, the an- cient philosophies all sink into skepticism and become extinct, but it is commensurate with the phenomena of the universe, as it deals with phenomena, and deduces its principles from them, and not them from its principles, 12 134 THE BACONIAN PHILOSOPHY. It is therefore, not like the ancient philoso- phies, a means of culture and progress for one people or epoch only, exhausting itself upon that people or epoch, but it is the means of culture and progress for all the nations and periods of the world. The nations which have been most under its influence have risen superior to all the rest of the human family, and have advanced progressively, and their speed is daily accelerated, to a degree of in- tellectual developement,and moral superiority, and political power, which seem to indicate that it is destined to form the type of the civilization of a greater part, if not of all the human race. And that this progress is like- ly to be perpetual, is also indicated by the fact, that England, the nation which has most assiduously cultivated this philosophy stands at the head of modern civilization, and is not only the great progressive and regenerative nation of modern times, but is also eminently conservative, possessing in happy combination the element of both progress and stability. She never loses sight of ancient landmarks in her progressive movements. How often, for THE BACONIAN PHILOSOPHY. 135 example, has she thrown her conservative in- fluence over the troubled waters of European politics, even when the commotion received its first impulse from the influence of her own principles of government! Scarcely has a quarter of a century elapsed, since she exer- ted all her power to rescue Christendom from political and moral ruin, brought about by a revolution with which at first she sympa- thized strongly. And it seems, at this dis- tance of time from the event, that if it had not been for her, all Europe would have ret- rograded in civilization. During the aw- ful storm of the French revolution, when al- most every government of Europe lay a wreck upon the tremendous tossings of the political waters, a gleam of hope still broke across the scene, as the wise men of the earth turned towards England and saw, that freigh- ted with the best interests of humanity, se- cure in her strength, she was riding out the storm. We have, therefore, strong reason to hope that the Baconian philosophy sanctified by the spirit of Christianity, will pour its sanative 136 THE BACONIAN PHILOSOPHY. floods over all the earth, and bring back all nations from the delirious wanderings of the a priori philosophy, to walk in the plain and sober paths of common sense. PART THE SECOND, CHAPTER FIRST. THE BACONIAN METHOD OF INVESTIGATION. The object of this chapter is to exhibit the Method of Investigation taught by Bacon in the Novum Organon, As the best mode of doing this, we will first sketch an outline of the Logic taught by Aristotle in his Organon, and show its nature and its province, and then sketch an outline of the Method of Investiga- tion taught by Bacon in his Novum Organon, and show its nature and its province, and compare the two, and point out their differ- ences. Let us then commence with an anal- ysis of the reasoning process, as it is of this, that the Organon of Aristotle treats. We frequently observe in the best writers upon science, a vagueness and contradiction of expression in regard to the reasoning pro- cess, that evince the greatest looseness of 12* 138 THE BACONIAN PHILOSOPHY. opinion in regard to its nature. We frequent- ly meet with such expressions as " the in- ductive process of reasoning/' u the true method of reasoning, which Bacon taught/' "the erroneous method of syllogistic reasoning which Aristotle invented/' and many other such expressions, which clearly indicate that the writers suppose, that there is more than one mode of reasoning. Nothing can be more erroneous than such a supposition. No matter what be the subject upon which the mind is employed, whether in the spiritual or mate- rial world — whether in metaphysics, ethics, politics, mathematics, or in the different bran- ches of natural philosophy, the reasoning process is always the same. The process is always from the known, or that which is as- sumed as known, to the unknown ; and is al- ways reducible to a syllogism. The syllogism is in fact the process of reasoning ; for though every argument does not pass through the mind in the strict logical form of the syllo- gism, yet in every instance of reasoning, all the parts of a syllogism are contemplated by the mind. Some seem to entertain the notion, THE BACONIAN rillLOSOrHY. 139 that the syllogism is a peculiar kind of rea- soning — that it is not the natural process of the mind in reasoning, but is an artificial mode invented by Aristotle. Let us test this notion, by analyzing an argument presented in its common form. u The world exhibits marks of design, it therefore has an intelligent au- thor." Now the process which takes place in the mind, in forming this argument, is the syllogism ; as will be seen, if we attempt to refute the argument. Suppose we deny the truth of the argument, we must do it upon one of two grounds. Either upon the ground, that the world does not exhibit marks of de- sign, or upon the ground, that even if does, still it may not have an intelligent author. An objection upon either of these grounds is a full denial of the argument. What does this prove ? Why, that the argument rests upon two assumptions. First, upon the assumption, that whatever exhibits marks of design has an intelligent author, and, secondly, that the world exhibits marks of design. The two assumptions are evidently the premises from which the conclusion is deduced ; for if either 140 THE BACONIAN PHILOSOPHY. of them be false, the conclusion must be false, and if both of them be true, the conclusion must be true. As then both of these assump- tions are absolutely essential to the truth of the conclusion, the mind must have contem- plated them in coming to the conclusion ; for otherwise it would not be warranted in form- ing any such conclusion. Indeed, it is im- possible to form such a conclusion, without considering both of these assumptions ; for they are the evidence upon which it rests. Now let us look back over what we have been doing, and we shall see that, in devel- oping the argument, we have formed it into a complete syllogism. As developed, it is thus : " Whatever exhibits marks of design has an intelligent author. The world exhib- its marks of design. Therefore, it has an in- telligent author." This is a complete syl- logism. The first sentence is the major premiss; the second, the minor; and the third, is the conclusion. The minor premiss was expressed in the argument as we first stated it ; but the major was not. When we denied the truth of the argument, we found, THE BACONIAN PHILOSOPHY. 141 4:hat in order to sustain it, we must adduce other evidence than was expressed 3 and the other evidence is the major premiss of the syllogism. The mind then, must have con- templated this major premiss ; else, it came to the conclusion upon insufficient evidence. In fact, the major premiss is implied in the minor; as it must always be : and therefore, the mind must of necessity have contemplated it. The argument as we first stated it, is the form in which we generally speak or write our arguments ; for we never express all the evidence which passes before the mind in argumentation, but use expressions which imply the truth of what is considered evident. When, therefore, we wish to analyze and de- lineate the process which takes place in rea- soning, we must consider every step of the argument — take hold of the attenuated clew, and pass along all the most winding and intri- cate passages of the mental labyrinth, and find out what is not usually expressed. If we do this with any argument whatever, and add to it all that is understood, it will then be a syllogism, or series of syllogisms. The 142 THE BACONIAN PHILOSOPHY very argument by which we have endeavour- ed to establish the point under consideration, may be formed into a series of syllogisms, by merely supplying what is understood. As we have established the point, that every argument, when stated in full and in logical order, is a syllogism, or a series of syllogisms, we will next ascertain what are the acts of the mind, which take place m the syllogism, as we shall thus ascertain what are the acts of the mind which take place in rea- soning. The fundamental principles of the syllo- gism are ; first, if two terms agree with one and the same third term, they agree with each other; secondly, if one term agrees and another disagrees with one and the same third term, these two disagree with each other. On the former of these principles, rests the validity of affirmative conclusions:; on the latter, of negative. In the argument above, to prove that the world has an intelli- gent author, we found out a third term, with which both the subject and predicate of the proposition agree, which third term is, THE BACONIAN PHILOSOPHY. 143 i m . whatever exhibits marks of design." Be- cause if both the subject and the predicate of the proposition agree with this third term, they agree with each other. We see, then, that in every affirmative syllogism there are three agreements. The major and minor terms agree with the middle term, and they therefore agree with each other. And that in every negative syllogism, there are two disagreements. Either the major or minor term agrees with the middle term, and the other disagrees with it, and they therefore disagree with each other. Now, how are agreements and disagreements ascertained ? Why, by comparison. The acts of the mind, therefore, which take place in the syllogism^ are a comparison of two terms, with a third, and if they agree with it, then an inference that they agree with each other; and if either of them agrees, and the other disa- grees with the third term, then an inference that they disagree with each other. All reasoning, therefore, proceeds by compari- son. We have exhibited this point, because we frequently meet with expressions, in the 144 THE BACONIAN PHILOSOPHY. best writers upon logic and metaphysics, and : also in the writings of all classes of authors, which imply that all reasoning is not by com- parison : and also because we have seen some able writers running to the opposite extreme, and confounding the simple act of compari- son with the reasoning process, which as we have shown, consists of several acts of com- parison, and an inference from them. We will now for the purpose of enquiring more minutely into the nature of the reason- ing process, take a syllogism to pieces, and examine its I parts, so as to ascertain their nature and their mutual relations to each other. The syllogism is composed of three pro- positions, two of which are the premises, and the other is the conclusion. For example, in the syllogism which we have been using all along, the proposition, " Whatever has marks of design has an intelligent author/' is the major premiss; the proposition, "The world, exhibits marks of design," is the minor premiss ; and the proposition, " The world, therefore, has an intelligent author," is the THE BACONIAN PHILOSOPHY. 145 conclusion. It is upon the mutual relations existing between these propositions; and upon the mutual relations existing between their respective parts, that all the rules of Logic are founded. It is intuitively manifest, that both the minor premiss and the conclusion, are embraced in the major premiss, as parts of a whole. If the major and minor propositions be granted, the conclusion must necessarily follow, indeed the truth of the conclusion is assumed in them. When, therefore, we as- sert the truth of the major and minor prem- ises, we virtually assert the truth of the con- clusion also. We see, then, that in every argument, the conclusion is contained or as- sumed in the premises, and that the conclu- sion is not a different truth from the premises, but is one of the truths contained or assum- ed in the major premiss, which is nothing more than a general truth, of which the con- clusion is a particular instance. When, there- fore, we draw a conclusion, we do not, strictly speaking, ascertain a new truth, but merely develop in a particular instance, a general truth known to us before. The great general 13 145 THE BACONIAN PHILOSOPHY. principle which governs these mutual rela- tions existing between the premises and con- clusion, is the fundamental principle of Logic, and is called in scholastic language the Ci Dic- tum de omni et nullo" of Aristotle. It is this : " Whatever may be predicated (affirm- ed or denied) universally of any class, may be predicated (affirmed or denied) in like manner of any thing comprehended in that class." The application of this principle to the major premiss, as comprehending the minor and the conclusion, is obvious : for if it can be affirmed universally of the class of things exhibiting marks of design, that they have an intelligent author, it can necessarily be affirmed so of the world, if it be one of the things comprehended in that class. This maxim may be called the formula of demon- stration, a general argument, of which every other is a particular instance. And the man who violates it in argumentation, is to the eye of enlightened reason guilty of as gross an absurdity as he who attempts to raise himself aver a fence by the straps of his boots. We have now given an outline of the Logic THE BACONIAN 1 PHILOSOPHY. 147 taught by Aristotle in his Organon : and will next introduce to our readers the Method of Investigation taught by Bacon in his Novum Organon. From the expressions quoted at the begin- ning of our analysis of the reasoning process, and from many such that are found in the best writers of every class, one might suppose that Lord Bacon had taught a new mode of reasoning : and that his Novum Organon was designed to supersede altogether the Organ- on of Aristotle. This is an entire misconcep- tion of the whole subject. The design of the Novum Organon was not to teach a new mode of reasoning ; but to teach a new method of investigation. The Novum Organon has, therefore a very different province from that of the Organon of Aristotle. The ^province of the latter is to analyze the process of the mind which takes place in reasoning ; and to furnish a model to which sound reasoning may be reduced and by which the correct- ness of every argument may be tested, in its conformity to the model; and to furnish rules relative to the whole matter, as we may have shown. 148 THE BACONIAN PHILOSOPHY But the Logic of Aristotle was supposed by its author and the other Greek philoso- phers to be an instrument of much more im- portance in the investigation of truth, than it really is, and was therefore applied to the in- vestigation of the sciences, and is called the a priori Method of Investigation, and it is as a method of investigation, that the Novum Organon is designed to supersede the Organ- on of Aristotle, as we will now proceed to show. The Greeks were an astute and exceedingly disputatious people, inordinately fond of dia- lectical disquisitions ; and it was in this spirit, that the Greek philosophers conceived that the reasoning process was the chief process in the investigation of the sciences, or in other words that, the a priori, was the true method of investigation. And it was at a period in the history of Greece when her philosophers were wholly given up to abstract studies, that Aristotle's Organon had its origin ; and it may be considered as a systematical developement of the method of investigation pursued by the Greek philosophers, who carried the a THE BACONIAN PHILOSOPHY. 149 priori Method of Investigation which had proved so successful in mathematical inquiries to which it is adapted; into physical and meta- physical inquiries, supposing that as in the mathematics, so in physics and metaphysics, every thing can be reasoned out from a few simple notions or principles. And in accord- ance with this opinion the Greek philoso- phers were always endeavouring to find out these simple principles in nature, which they supposed would be productive of such rich results in science. In psychology, we find some maintaining the doctrine of innate gene- ral ideas or principles from which not only all metaphysical but all physical truths also were to be reasoned out ; and in physics, we find one making water, another, the infinitude of things, a third, air, and at last Aristotle, making form and privation combined with matter, the principles of all things: and though Aristotle did not maintain that these simple notions or principles were an innate knowledge of the mind, yet he seemed to think that they might be recognised affirmatively at the first glace of contemplation of an instance furnish- 13* 150 THE BACONIAN PHILOSOPHY. ed through sensation, and that therefore, the chief process in the acquisition of truth, is in deducing conclusions from principles, and not in ascertaining principles. And these miser- able abstractions were the clews by which the labyrinths of nature's secret places were to be passed through, and the truths of physics and metaphysics ascertained by reasoning from them. This misapplication of Logic as a method of investigation could not but lead to error. For Logic does not guaranty the truth of the premises of an argument, unless they are conclusions from previous arguments, but always proceeds upon the hypothetical truth of the premises. It merely guarantys the truth of the conclusion, as an inference from the premises ; its province as we have shown, being to deduce conclusions from ad- mitted premises. Its tendency, therefore, is to make us overlook the truth of the premises; as it furnishes no rule in regard to their truth, but merely in regard to the truth of the con- clusion as an inference from them. And this is the very evil which it produced. This misapplication of Logic as a method THE BACONIAN PHI LOSO-FI'.Y, 151 of investigation, led inevitably to the most absurd theories in physical science imagina- ble. As an example, we will cite Aristotle's argument in proof of the immutability and incorruptibility of the heavens, as it is. exhib- ited by Galileo. " 1st. Mutation is either generation or corruption." " 2d. Generation and corruption only hap- pen between contraries." " 3d. The motion of contraries is contra- ry." " 4th. The celestial motions are circular.'* u 5th. Circular motions have no contra- ries." u A. Because there can be but three sim- ple motions." a 1st. To a centre." " 2d. Round a centre." "3d. From a centre." " B. Of three things, only one can be contrary to one." " G. But a motion to a centre is manifestly the contrary to a motion from a centre." "D. Therefore, a motion round a centre 152 THE BACONIAN PHILOSOPHY. (i. e. circular motion,) remains without a contrary." " 6th. Therefore, celestial motions have no contraries ; therefore, among celes- tial things there are no contraries ; there- fore, the heavens are eternal, immutable, incorruptible, and so forth." Such is a striking example of both the method and the results of the ancient mode of philosophizing. In it are exhibited a total disregard of facts and phenomena and a pom- pous and conceited affectation of system, which admirably illustrates the intellectual pride and vanity of the Greek philosophers, who paid no regard to their premises, as facts founded in nature ; but vainly hoped to rear up a system of natural philosophy correspond- ing with the indications of nature, merely by deducing conclusions from assumed premises not ascertained by observing nature, but pure- ly the fictions of their own imaginations. And to just as gross absurdities were the Greek philosophers led in mental philosophy, by their disregard of facts and phenomena, as they were in physical. We will cite as an THE BACONIAN PHILOSOPHY. 153 example, the doctrine of sensation, or the mode in which the mind perceives objects as taught in the Peripatetic school. A kind of images, or sensible species as they were call- ed, were supposed to come off from all ob- jects and to pass to our different organs of sense, and were by them admitted to the nerves, and through them conveyed to the brain, where they were impressed as the en- graving of a seal on wax, and were then re- fined into intellectual species, after the mind fully apprehended them. We might cite many other examples of like absurdity : but our object is merely to illustrate the point un- der consideration. The Logic and philosophy of Aristotle ob- tained the greatest favor at Rome under the Caesars. At an early period however, in the Christain world, Plato had displaced Aristotle, and his continued the most generally receiv- ed philosophy until the close of the fifth cen- tury, when the influence of Aristotle began to prevail again, and though it declined a lit- tle during the sixth century, at the close of the seventh, it was every where triumphant 154 THE BACONIAxN PHILOSOPHY. throughout the civilized portions of Europe, Asia and Africa. Christians, Jews and Ma- hometans bowed before his authority. Com- mentaries, paraphrases, summaries and disser- tations on his works were composed without number in both Arabic and Latin. His works were appealed to in all disputes as infallible au- thority : and none dared dissent from the a Great Master, " During this period, the study of nature was still more neglected than it had been by the Greeks. Mere .abstrac- tions, figments of the mind, usurped the place of even the few facts contained in the Greek philosophy. Men's minds were in a continual ferment about occult qualities and essences— about proportion, degree, infinity, formality, and innumerable other abstractions ; and such was the height to which controver- sy ran about these chimeras of the mind, that it often resulted in bloodshed, and well-nigh convulsed kingdoms. Every one seemed to think that, " the chief end of man, is to con- tradict his neighbour, and to wrangle with him forever. " The different parties had their rival chiefs decked out in all the titles of phi- TtJE BACONIAN PHILOSOPHY. 155 losophical heraldry, such as " the invincible, " " the most profound," u the angelical," " the irrefragible doctor, " to lead them on to the wordy war. And now the most absurd no- tions were worked up into systems of phi- losophy. As the great master Aristotle had taught, as we have shown, that a uniform circular motion was the only motion consis- tent with the perfection of the heavenly me- chanism, this notion was worked up into a most unwieldy and complicated theory of as- tronomy^ exhibiting the sun, moon and plan- ets revolving in circles, whose centres were carried round in other circles, and these again in others, and so on without end— " cycle upon epicycle, orb on orb," throughout the in- finitude of space. But a still more absurd astronomical theory was gravely presented to the world in the sixth century by Cosmas Indopleustes, who maintained, says Maclau- rin in his account of Sir Isaac Newton's phi- losophical discoveries, that " the earth was not globular but an immense plane of a great- er length that breadth,environed by an unpass- able ocean. He placed a huge mountain to- 158 THE BACONIAN PHILOSOPHY. wards the north, around which the sun and stars performed their diurnal revolutions ; and from the conical shape which he ascribed to it, with the oblique motion of the sun, he ac- counted for the inequality of the days and the variation of the seasons. The vault of Heav- en leaned upon the earth extended beyond the ocean, being likewise supported by two vast columns: beneath the arch, angels con- ducted the stars in their various motions. Above it were the celestial waters, and above all he placed the supreme heavens." Such then was the state of knowledge produced by implicitly obeying authority, and following the ancient method of philosophizing, of endeav- ouring to deduce systems of philosophy from a few imaginary principles — of misapplying Logic as a method of investigation. It was during this state of knowledge, though light had begun to break in upon the darkness, that Lord Bacon was born. While yet a student at Trinity College, Cambridge, he discerned the vagueness and inutility of the existing state of knowledge ; and as he advanced in age, he saw the more clearly THE BACONIAN PHILOSOPHY. 15? the utter worthlessness of all the reigning speculations of the day ; for, there being no connection whatever between them and the arts, they did not minister at all to the com^ forts of man, or arm him with any power o- ver nature. As this great genius meditated upon the immense growth of pernicious error which had sprung up in every province of knowledge, he plainly saw, that it was in a great measure the product of the extensive influence which Aristotle possessed in the schools, diverting the minds of men from the study of nature to the study of his doctrines ; and that the authority of Aristotle must be overthrown, before man could be brought back into the true paths of science. For although the discoveries of Copernicus, Kep- ler and Galileo had in some degree broken the magic spell of the enchanter of Sta- gira, it remained for a genius of a loftier tone to show its delusion and folly by pointing out its nature ; and to rouse up the minds of men from slavish obedience to authority, by pour- ing into them the quickening influences of his own free spirit. All this Bacon designed to. L58 THE BACONIAN PHILOSOPHY. accomplish by his Installation of the Scien- ces ; and to lead men back into the true paths of science, from which they had so long wan- dered. The Installation of the Sciences, was de- signed by Bacon to consist of six parts : but as he wrote but little of the third, fourth, fifth and sixth parts, we will say nothing of them. The first part is the Advancement of Learn- ing in which he sketches out all the depart ments of knowledge and defines their limits ; and shows the degree of cultivation in each. In concluding this part of his great work, he says, u thus have I made, as it were, a small globe of the intellectual world as truly and faithfully as I could discover, with a note and description of those parts, which seem to me not constantly occupate or well converted by the labour of man. " The second part of the Instauration of the Sciences, is the Novum Organon, which it is our object now to illustrate. As, in the Ad- vancement of Learnings Bacon sketched a map of the sciences, in the Novum Organon, he de- velops the method by which they are to be THE EACONIAN PHILOSOPHY- 159 investigated. He here proclaims the great truth, and develops it, that the knowledge of the philosopher does not differ in kind but only in degree, from that of the peasant — that the whole of philosophy is founded on obser- vation, and is nothing more than a classifica- tion of facts and phenomena presented in na- ture, rising first, from particulars, to classifi- cations of the lowest degree of comprehension, and then from these, to those of a higher de- gree, and so on, until we arrive at classifi- cations of the 'highest degree comprehend- ing all the subordinate classifications. And that these classifications are the only true general conceptions ; as they are the only ones which have any thing corresponding to them in nature ; and that the ideas or forms of Plato, and the empirical general conceptions of Aristotle have nocounterparts in nature, but are the mere fictions of their own imaginations, and therefore are not a proper foundation of science. In a word, he declared that all philosophy is written in the book of nature, the material and spiritual worlds. He set forth this great truth in the 160 THE BACONIAN PHILOSOPHY, very first proposition of the Novum Organon: "Manas the servant and interpreter of nature, does and understands as much as his obser- vations on the order of nature, either with re- gard to things or the mind, permit him, and neither knows, nor is capable of more." The spirit of this philosophy is humility. It teach- es that in order to become philosophers truly so called, men must cast off that intellectual pride which vainly strives to find out the se- crets of nature by mere reasoning, and be- come as children, reading in humility the simplest lessons in the book oi nature. " The access to the kingdom of man which is found- ed on the sciences, ?5 says Bacon, ".resembles that to the kingdom of Heaven, where no admission is conceded except to children. " Noble and sagacious comparison ! With what philosophic forecast does it portray the spirit of true philosophy ! For as those who recognise the doctrine of humility in divine truth, have planted, upon the strongest for- tresses of paganism, the white banner of Chris- tianity, with the lonely star of Bethlehem shedding its mild teams from its ample folds THE BACONIAN PHILOSOPHY. 161 as it waves over the worshippers of the true God, so those who recognise it in human truth, have pushed their conquests into every province of nature, and even scaled the very Heavens, and planted the standard of the Ba- conian philosophy upon the remotest star, de- monstrating by their success that the hum- bling precept, "become as little children," is as true in philosophy as in religion. It is obedience to this precept which confers on man all his power over nature — gives him access to the kingdom founded on the scien- ces. The method of investigation, according to this view of philosophy, proposed by Bacon in his Novum Organon, he calls Induction, which means iC a bringing in ;" because it proposes to bring into philosophical investi- gations facts diligently sought out in nature, and after carefully examining them in all pos- sible lights, to educe some general principle from them which they clearly indicate. The developement of this method, by showing its nature and efficiency, and exposing the sour- ces of error in philosophical investigations and 14* 162 THE BACONIAN PHILOSOPHY laying down precepts for conducting them right, so as to enable the humble and sincere inquirer to guard against error, constitute the Novum Organon. Such then is the remedy which Bacon proposed for rectifying the evils of the ancient philosophy ; and for enabling man to establish a true practical philosophy that would extend his empire over all the do- minions of nature. He sketched a chart to guide the humble voyager on the vast ocean of knowledge ; and erected beacons to warn him where his barque might be stranded. It is evident from this view of the subject that the Novum Organon, was not designed to teach a new mode of reasoning; and thus to supersede the Organon of Aristotle in its legitimate province of analyzing the process of reasoning, and exhibiting rules for conducting it aright : but merely to supersede it as an in- strument of investigation in the sciences, to which it had been misapplied both by its au- thor and his followers, especially those of mod*- ern times. The Novum Organon is not in fact a treatise on lo^ic at all : but rather a treatise on evidence ; for it treats more partic- THE BACONIAN PHILOSCFHY, 163 ularly of premises, than of conclusions ; and the premises are the evidence, which prove the conclusion of an argument ; for when we set out with a conclusion which is then called a proposition, the evidence which we adduce to prove it w T ould constitute the premises, if we set out with the premises, in order to de- duce the conclusion from them. Lord Bacon, after surveying the whole of ancient philoso- phy, saw that it was not sustained by legiti- mate evidence-— that the premises (so to speak) of the arguments were either plainly false, or mere assumptions not proved ; and he proposed in his Novum Organon, that men should examine facts and phenomena (the only legitimate evidence,) before they form theories^ — interpret nature and have leg- itimate premises, before they deduce conclu- sions. He did not design to show that their conclusions w r ere not logically deduced from their premises, or that the syllogistic rules laid down by Aristotle for conducting this process were eroneous. But if Bacon did design to teach a new mode of reasoning, he has signally failed of 164 THE BACONIAN PHILOSOPHY. his purpose ; for we have shown that the syllogism is the process which must take place in all correct reasoning; and we will now proceed to show that Induction is a very different process, and not a process of reason- ing at all. What is Induction ? It may be defined, a process of investigation and of collecting facts and phenomena, either with or without a view, to establish some general principle already suggested to the mind. It is manifest that the mere investigation and collection of facts and phenomena without a view to establish some general principle al- ready suggested to the mind, is not a reason- ing process. It therefore, only remains to examine the other, the investigation and col- lection of facts and phenomena with a view to establish some general principle already suggested to the mind. In this last case, the investigation and collection of facts and phe- nomena, is conducted on the supposition or presumption of the existence of a general principle or law ; and is directed with a view to establish it, by the examination of a suffi- cient number of facts and phenomena. For THE BACONIAN PHILOSOPHY. 165 example : — A naturalist, after seeing for the first time, a duck or any other water-fowl, might be led to infer that all water-fowl have web-feet; and might therefore proceed to search for other water-fowl, until he found the goose, the pelican, the swan, &,c. ; and would then be convinced of the truth of the gene- ral principle, that all water-fowl have web- feet. Now, this is certainly not a process of reasoning; for it/is conducted upon the sup- position or presumption merely, of the exis- tence of the law or general principle, and not upon the absolute certainty of its existence ; rfor it would then not .be investigation, but demonstration or reasoning from known pre- mises, to something taken for granted in those premises, as we have shown reasoning always to be. The inductive process is not governed by .principles of logic, but by principles of evidence. For instance : — In the example above, the naturalist supposed from the fact, that one water-fowl, the duck, has web-feet, that all water-fowl have web-feet. Now, this is evidently a mere supposition from tes- timony not sufficient to convince the natura- 166 THE BACONIAN PHILOSOPHY. list; he therefore searches for other water- fowl (other testimony) and finds the goose, the pelican, the swan, &,., and is convinced by this accumulated testimony of the general principle that all water-fowl have web-feet. The mental determination is effected by tes- timony, and not by rules of logic. The con- clusion is not implied in the very conception of the premises, as is always the case in rea- soning ; but it is warranted by the probabili- ties founded in the analogies of nature and in the constitution of the human mind. The inference is founded upon material relations, and not upon logical. The conclusion is probable ; but not necessarily certain, as is always the case in logic ; for logic never proves with any but the highest degree of certainty, the inference being never deduced from probabilities, but necessitated by the very laws of thought. The relation between the premises of an argument and the conclu- sion, is that of reason and consequent ; and the material relations of the objects express- ed by the terms have nothing to do with the inference of the one from the others ; for in THE BACONIAN PHILOSOPHY. 167 reasoning^ the inference is effected; vi termini et rationisy and not vi materiae. And reason- ing always proceeds from a class to a parti- cular; or from a class of greater comprehen- sion; to one of less ; and every class is estab- lished by induction : to make a class then; a prerequisite of induction; as we must do, if we make induction; reasoning; would be ab- surd ; for every induction would then be the result of some previous induction; in infinit- um ; and it would make our highest abstrac- tions or generalisations; the first in order of time in the acquisition of knowledge; which is a psychological doctrine that is repudiated by the whole Baconian philosophy ; as will be seen in the next chapter. It is manifest, we think, from this analysis, that induction is the reverse of the syllogism. Induction proceeds from particulars to a class of low degree; and from several classes of a low degree to those of a higher; until we ar- rive at those of the highest degree. On the contrary; syllogism proceeds from classes of the highest degree to those of a lower, and from those of the lowest degree to particulars. 168 THE BACONIAN PHILOSOPHY. The two together constitute one complete system of precesses by which knowlehge is acquired and perfected. For very often we cannot be satisfied that we have arrived at a correct inductive conclusion or statement of a law of nature, until we make such conclu- sion or law a ground of argument, and show by strict reasoning that the phenomena ob- served are consequences of it. For exam- ple : in reasoning from the law of gravity, we discover, by the application of the gene- ral laws of dynamics, that all the planets must attract each other, and therefore draw each other out of the orbits in which they would have moved, if acted upon by the sun only ; and thus circumstances are discovered by which our general conclusion is strengthened, and which could not have been discovered otherwise, as it required some such conclu- sion which could only be obtained by strict reasoning, to direct attention to such minute inquiries ; and a correct theory is thus ob- tained. This use of reasoning in inductive inquiries will be more particularly explained THE BACONIAN THILOSOPHY. 169 in the sequel, when we speak of the appli- cation of mathematics to physical inquiries. In further illustration of the nature of in- duction, we will now inquire into the nature of the methods of Analysis and Synthesis. We frequently see Analysis called the induc- tive process, and Synthesis called the hypo- thetical process, the process of the ancients. This is very erroneous. Synthesis is just as much of an inductive process as analysis ; and is, in fact, more extensively used by the Ba- conian philosophers than analysis. Analysis and synthesis are terms derived from the an- cient Greek geometricians ; and are of quite a different nature in the mathematics from what they are in the other sciences. In mathemat- ics synthesis is just the reverse of analysis ; but it is not so in. the sciences of contingent truth. In these, analysis is the process of in- vestigation by observation and experiment; and synthesis is the process of explaining other phenomena^ by means of the general fact or law ascertained by analysis. Synthe- sis is just as much of a process of investiga- tion as analysis; and is more frequently used 170 THE BACONIAN PHILOSOPHY- as such. For we are frequently led to an in- ference analytically, without our induction of facts being sufficiently extensive to satisfy us ; we therefore bring to our aid synthetically facts which we had not before examined. At the time we are explaining facts syntheti- cally we are establishing the inference which we derived analytically; because if the infe- rence will explain the facts; the facts will, .of course,, support the inference. Analysis and synthesis are, therefore, both processes of in- duction ; for by both of them we enlarge the number of our facts. Indeed, most of the dis- coveries in the inductive philosophy have been made chiefly by synthesis. The phe- nomenon of the rainbow was explained by it. Sir Isaac Newton, by experiment with the prysmatic spectrum, discovered that light is composed of seven rays, of different colours, and of different degrees of refrangibility. By this fact, thus analytically established, he ex- plained the phenomenon of the rainbow syn- thetically ; and the phenomenon thus explain- ed, establishes the fact that light is composed of seven rays of different colours and differ- THE BACONIAN PHILOSOPHY. 171 ent degrees of refrangibility. The phenom- enon of the rainbow could never have been explained analytically. We might have look- ed at it forever, and would still be unable to explain its cause from mere observation, no matter how minute. The science of astrono- my has been reared chiefly by synthesis. Newton, from an examination of the phenom- ena of motion on the earth, inferred the prin- ciple of gravity, and by the principle of gravity thus analytically ascertained, he ex- plained synthetically the phenomena of the whole solar system. It .would have been impossible ever to have explained these phe- nomena by analysis. In the preface to his Principia, Newton says : "All the difficulty of philosophy seems to consist in this : from the phenomena of motions, to investigate the forces of nature, and then from these forces to demonstrate the other phenomena-; and to this end the general propositions hope, fear, anger, and all the other emotions; and upon the relations of the phenomena of both of these classes are founded certain prac- tical rules or arts. On the first, are founded logic and the method of investigation; and on the latter, are founded, aesthetics and the fine arts. It is with the first class, those 'Note. — We are well aware that the phenomena of the will constitute a distinet class, but the division which we have made is sufficiently accural* for our purpose. 208 THE BACONIAN PHILOSOPHY. which relate to the intelligence, that we have to deal in the investigation which we are pur- suing ; as it is amidst them that the connex- ion between psychology and logic, and be- tween psychology and the method of inves- tigation is to be discovered. Psychology by , analyzing the phenomena of reasoning, ex- hibits the fundamental laws of thought, which govern the mental acts in every demonstra- tion : and logic exhibits the illative rules by which the conclusion is evolved out of the premises. This then is the point of contact between psychology and logic, the boundary where the one ends, and the other begins. Psychology also exhibits, by analyzing the phenomena of induction, the fundamental law • of thought which governs the mental deter- mination in every act of belief that the future will be like the past, or that like causes will produce like effects: and the method of in- vestigation exhibits the inductive rules or re- gulative principles by which the general con- clusion is inferred from the particular instan- ces. And this is the point of contact between psychology and the method of investigation. THE EACOxNIAN PHILOSOPHY. 209 It is at these points of contact, that psycholo- gy supplies the deficiencies of logic and of the method of investigation — gives light where they give none ; for logic and the method of investigation pre-suppose psychology, and de- pend upon it for their whole strength. But psychology penetrates still further into the mysteries of human thought, and as rea- soning and induction assume the truth of the facts attested by sensation, consciousness and memory, it also analyzes their phenome- na, and evolves the fundamental laws of be- lief which govern all our knowledge derived from these sources respectively, and thus as- certains the very elements of human knowl- edge, which admit of no explanation, which borrow no light from any thing antecedent, but are self-luminous; and in this way sup- plies every thing which is assumed as true in logic and the method of investigation. With these preliminary remarks, indicating in a general way the connexion between psychol- ogy and logic, and between psychology and the method of investigation, we will now pro- ceed to exhibit the two great opposite sys- 210 THE BACONIAN PHILOSOPHY- terns of psychology and the correlative meth- ods of investigation. The great problem which lies at the thresh- old of every inquiry into the phenomena of the human mind, and gives to every system of psychology its distinctive feature, in the point of view in which we are considering the sub- ject (its connexion with logic and the meth- od of investigation,) is, what is the origin of our ideas, "those simple notions into which our thoughts may be analyzed, and which may be considered as the principles or elements of human knowledge ?" There never have been, and never can be, more than two theories in regard to the solution of this problem. One is the theory of innate ideas, or primitive cognitions which are not the product of the mind's own activity, but are its original fur- niture ; the other, the theory, that all our ideas are founded ultimately in experience, and are acquired through sensation and conscious- ness. These two opposite psychological the- ories are the correlatives of the two opposite methods of investigation, the a priori method, ( which we have shown in the last chapter, to the Baconian ruiLosorur. 211 be nothing more than an application of the Aristotelian logic out of its proper sphere,) which makes all absolute verity to depend upon certain innate principles, or elements of knowledge, from which the mind starts and reasons out all science as legitimate deductions from them, in which the series of logical de- ductions will correspond with the series of facts subsisting in nature; and the inductive or Baconian method, which bases all knowl- edge upon experience, and considers princi- ples as mere generalized facts obtained by the observation of particular phenomena. We will first treat ot the theory of innate ideas and then show that it is the psychological correlative of the a priori method of investi- gation. The theory of innate ideas has gppeared under different phases ; and more distinctly in the writings of Plato amongst the ancients, and Des Cartes amongst the moderns, than the writings of any other philosophers. Pla- to representing one phasis of this theory, and Des Cartes, the other. Plato held that there are in the soul certain innate ideas which 212 THE BACONIAN PHILOSOPHY form the basis of our conceptions and consti- tute the principles of our knowledge ; and that these innate ideas were in the soul in a prior state of existence^ and are now suggested to the mind ; by individual objects presented to the senses. That the process of acquiring knowledge is mere suggested reminiscence; and the reminiscence is in proportion as the mind becomes acquainted with individual ob- jects. For example : in the dialogue entitled "Phaedon/ 5 he asks, "Is it upon seeing equal trees equal stones and several other things of that kind ; that we form the idea of equality ; which is neither the trees nor the stones, but something abstracted from all these objects ?" And he answers the question thus : " Before we begin to see, feel, or use any of our senses, we must have had the knowledge of this in- tellectual equality ; else we could not be ca- pable of comparing it with the sensible ob- jects, and perceive that they have all a ten- dency towards it, but fall short of its perfec- tion." " That is a necessary consequence from the premises." THE BACONIAN PHILOSOPHY. 213 " But is it not certain that immediately after our birth, we saw, we heard and made use of other senses?" " Very true." a Then it follows that before that time, we had the knowledge of that equality ?" u Without doubt." " And of course, we were possessed of it before we were born V) " I think so." ci If we possessed it before we were born, then we knew things before we were born, and immediately after birth ; knew not only what is great, what is small, what is equal, but all other things of that nature." " For what we now advance of equality, is equally applicable to goodness, justice, sanc- tity, and in a word to all other things that have a real existence ; so that we must of necessi- ty have known all these things before we came into this world." It is manifest from this extract ; that Plato maintained that all our abstract notions are in the mind when we come into this world and are of course, first in the order of acquisition ; 214 THE BACONIAN PHILOSOPHY". and that it is by the light of these notions, or ideas as he called them, that we comprehend what we observe in this world — that it is by the abstract innate idea of equality, that we judge of the instances of equality exhibited in experience ; by the abstract innate idea of goodness, that we judge of the instances of goodness, and so of every other innate idea. Thus maintaining that man has in his mind, an innate standard of truth, with which he can compare every thing, and test its ver- ity. We will now exhibit the other phasis of this theory, as taught by Des Cartes. He held that the idea of the infinite, and all other ideas which are particularizations of it, are not acquired ideas, but are innate in the mind, having been communicated to it, or interwo- ven into its very being by the Creator, to be the foundation of all its acquired knowledge, and the guide of its future reasonings. Though he did not maintain that these ideas were always present in the mind : " When I say" (says he) " that an idea is born in us, or that it is naturally imprinted on our souls, I do THE BACONIAN PHILOSOPHY. 215 not mean that it is always present in thought, for this would be contrary to fact ; but only that we have in ourselves the faculty of pro- ducing it." It is evident that these doctrines of Plato and Des Cartes are substantially the same, and exhibit only different phases of the the- ory of innate ideas. We will now show that the theory of innate ideas is the psychological correlative of the a priori method of investigation, and is the psychology assumed in that method ; and that both Plato and Des Cartes actually adopted and used that method. Thus prov- ing the proposition, both by philosophical analysis and historical fact. The least reflection will discover that the a priori method of investigation is the psy- chological correlative of the theory of innate ideas. For if all the principles or elements of our knowledge are an original furniture of the mind, and the most comprehensive princi- ples stand first in the order of time in the mind, are those first developed to the intelligence, (as the theory of innate ideas teaches) — 216 THE BACONIAN rHILSDSOPHY. then the only method by which the mind can extend the sphere of its knowledge and build up this knowledge into science, is to combine these principles and deduce from them con- clusions corresponding to the real particulars subsisting in nature; and the chronological and logical order of our knowledge is the same. And it is also clear that the a priori method of investigation assumes the theory of innate ideas or principles ; because if there are no innate principles, or if, in other words, a reason could be given for every truth, no process of deduction (and the a priori method of investigation is the process of deduction or reasoning, as we have shown in the last chapter) could ever have a beginning; for to make reasoning the process of discovering first principles, would be to go on to infinity ; because, in every argument or process of rea- soning, something must be assumed as true, from which our reasonings set out, and on which they ultimately depend. Where then, is the first starting-point to be had, if it be not innate ? It must be innate, or else it is furnished by induction : and if it is furnished THE BACONIAN PHILOSOPHY. 217 by induction, the a priori method of investi- gation can have no existence : but is in reali- ty, what it was in the hands of Aristotle, (who did not believe in innate principles, but, that they are ascertained by induction,*) nothing more than reasoning from principles formed from a hasty or imperfect induction. It is evident then that the a priori method of investigation assumes the theory of innate ideas or principles — requires them for its starting-points; and thus is developed the point of affiliation and doctrinal identity be- tween them. It is thus manifest from philosophical ana- *\ote. — It may perhaps be enquired, why it is, that Aristotle, who main- tained the theory of mind enunciated in the principle nihil intellectu. quod non prius in sensu, yet maintained the a priori method of investigation. It is clear, that Aristotle, is either inconsistent with himself, or that he meant by this doc- trine, merely that sensation must precede all knowledge. But there are doctrines setforth in his writings upon the point under consideration, which it is diffi- cult to reconcile, and which show that his opinions were not very definite. It is certain however, that he did not, like Plato, maintain that there are cer- tain innate ideas in the mind, independent of the mind's activity, but seems to have maintained the doctrine ascribed to him on the 149 — 50 pages of this dis- course, which to a great extent is an a priori theory much like that of Kant, and consequently, so far as it is an a priori theory, is consistent with his method of investigation. But let it be borne in mind, that our object in this part of our discourse, is not to show, that all who maintain the a priori method of in- vestigation, also maintain the doctrine of innate ideas, but to show, that, that method necessarily assumes this false doctrine for its basis, and is therefore fal- lacious itself. 19 218 THE BACONIAN PHILOSOPHY. lysis of the theory of innate ideas, and of the a priori method of investigation, that they are psychological correlatives. We will next show, that they are correlatives in the history of philosophy also — that they are historically, as well as philosophically related — that Plato and Des Cartes adopted and used the a priori method of investigation, as well as maintain- ed the doctrine of innate ideas. In the Phaedon, the same treatise from which we extracted the remarks relative to in- nate ideas, and the one in which Plato gives, though in an incidental way, his peculiar psy- chology, we have also a delineation of Plato's method of investigation ; though this is given in an incidental way too ; for in investigating the subject of the treatise, the immortality of the soul, he had to use both his psychologi- cal theory and his method of investigation. " Have seeing and hearing, " says Plato, "any thing of truth in them, and is their tes- timony faithful ? Or are the poets in the right in saying that we neither see nor hear things truly ? For if these two senses of seeing and hearing are not trustworthy, the THE BACONIAN PHILOSOPHY. . 219 others which are much weaker, will be far less such. Is it not by reasoning that the soul embraces truth ? And does it not reason better than before, when it is not encumber- ed by seeing and hearing, pain or pleasure ? When, shut up within itself, it bids adieu to the body, and entertains as little correspon- dence with it as possible ; and pursues the knowledge of things without touching them. Now the simplest and purest way of examin- ing things, is to pursue every particular thought alone, without offering to support our meditations by seeing or hearing, or backing our reason by any other corporeal sense ; by employing the naked thougfit with- out any mixture, and so endeavouring to trace the pure and general essence of things with- out the ministry of the eyes or ears : the soul being, if I may so speak, entirely disen- gaged from the whole mass of the body, which only encumbers the soul, and cramps it in the quest of wisdom and truth, as often as it is admitted to the least correspondence with it. If the essence of things be ever known, must it not be known in the manner 220 THE BACONIAN PHILOSOPHY. above mentioned ?" Plato exhibits his meth- od of investigation still more clearly in the following remarks extracted from the same treatise : — u After I had wearied myself in examining all things, I thought it my duty to be cautious of avoiding w T hat happens to those who contemplate an eclipse of the sun ; for they lose the sight by it, unless they be care- ful to view its reflections in water or some other medium. A thought much like to that came into my head, and I feared I should lose the eyes of my' mind, if I viewed objects with the eyes of my body, or employed any of my senses in endeavoring to know them. I thought I should have recourse to reason, and contemplate the truth of all things as re- flected from it. It is possible the simile I use in explaining myself is not very just : for I cannot affirm that he who beholds things in the glass of reason, sees them more by reflec- tion and similitude than he who beholds them in their operations. However, the way I fol- lowed, was this ; from that time forward I grounded all upon the reason that seemed the best, and took all for truth, that I found THE BACONIAN PHILOSOPHY. 221 conformable to it, whether in effects or causes ; and what was not conformable I rejected, as being false. " In these extracts we see that Plato held that u it is by reasoning that the soul em- braces truth, " and that the mind has the light of all truth within itself, and all the material within itself, upon which to exert the reasoning process ; and that it does not stand in need of the ministry of the senses to gain any information — in a word, that all philosophy is built up by reasoning from or upon innate ideas; for that all the phenomena in nature are but copies of these innate ideas, and are known to the mind, only by compar- ing them with these innate ideas and observ- ing their resemblance to them as their types and models. That the a priori method of investigation was c that used by Des Cartes also, is clearly manifested in his writings. He founded all knowledge upon a logical basis — upon de- monstration ; and considered that the object of philosophy is to deduce by reasoning from first causes, rules for the conduct of life and 19* 222 THE BACONIAN PHILOSOPHY for the various arts. " It is clear/ 5 says he, " that we shall follow the best method in phi- losophy if from our knowledge of the deity himself, we endeavour to deduce an explica- tion of all his works ; that so we may ac- quire' the most perfect kind of science, which is that of effects from their causes." In ac- cordance with this view of the method of in- vestigation to be used in physical science, is his theory of the mind; for he maintains that the idea of God, which he makes the start- ing-point in natural philosophy, is innate in the mind. - Thus basing natural philosophy in psychology, and making it necessary to es- tablish the foundation of psychological truths before certainty can be attained in physical truth. In order then to establish the founda- tion of 'psychological truth, he makes doubt the foundation of certainty and the starting- point in, human knowledge. "It is not to- day," says he, " for the first time that I have perceived in myself that, from my earliest years, 1 have received a great many false opinions as true, and that what I have built upon principles so badly ascertained, can be THE BACONIAN PHILOSOPHY. 223 only very doubtful and uncertain. And ac- cordingly, I have decidedly judged that I must sincerely undertake some time in my life to rid myself of all the opinions I had be- fore taken upon trust, and begin altogether anew from the foundation, if I would estab- lish any thing firm and constant in science. 55 Rejecting then, the knowledge of every thing, and plunging into absolute skepticism, he sets about to prove his own existence, as the first problem in knowledge ; and does it by this argument: — "I think, therefore I exist. 55 Satisfied, that by this argument and the application of the principle contained in it, he had proved the reality of every thing revealed in consciousness — the reality of his own existence, his own thoughts, passions, &c, his next difficulty was to pass out of the sphere of consciousness, and prove the reality of things external to himself. In ofder to do this, he must find some fact revealed in con- sciousness, (whose phenomena he .had proved to be worthy of credit) as the starting-point of the argument. This fact is the idea of a supremely perfect being, which he finds in 224 THE BACONIAN PHILOSOPHY. his mind. He concluded, that as the mind of man is finite, it could not have produc- ed by its own activity, this idea of the infi- nite i but that this idea must have some real object corresponding to it — which object is God — or in other words, that the idea of the absolute and infinite must have, from their very nature, a real object subsisting in time, corresponding to it. " If we carefully exam- ine/' says he, " whether existence belongs to a being supremely powerful, and what sort of existence, we shall find ourselves able clearly and distinctly to know, first, at least, possible existence agrees with him, as well as with all other things of which we have in ourselves any distinct idea, even those which are com- posed of fictions of our own mind : and next, because, we cannot think existence is possi- ble, without knowing at the same time — keeping in mind his infinite power — that he can exist by his own force, we conclude that he really exists, and that he has been from all eternity ; for it is very evident from the light of nature, that that which exists by its own force, exists always ; and thus we shall know THE BACONIAN P1IIL0S0PIIV. 225 that necessary existence is contained in the idea of a supremely powerful being, not by a fiction of the understanding, but because it belongs to the true and immutable nature of such a being to exist ; and it will be easy for us to know that it is impossible for this su- premely powerful being not to have in him- self all other perfections that are contained in the idea of God, in such sort, that, of their own proper nature and without any fiction of the understanding, they are always joined together and exist in God." By this ar- gument Des Cartes satisfied himself, that the existence of a God is proved from the exis- tence of the idea of such a being in the mind, and that thus the existence of an external re- ality is proved — that the boundary of con- sciousness is passed, and two orders of ideas are established : viz : himself, and the extern- al reality ; the proof of himself, resting upon his methodical doubt, "I think, therefore I ex- ist," and the proof of the existence of the ex- ternal reality, resting upon an idea corres- ponding to it in his mind. Returning again into consciousness, he finds there, the idea of 226 THE BACONIAN PHILOSOPHY. thought, and the idea of extension, under one or the other of which, he maintained, are embraced all other ideas ; and as these ideas are radically distinct, he concluded that the substances of which they are respectively the attributes are distinct also. The world, then, is composed of two classes of beings, spirit and matter, they being the substances of which thought and extension are the essen- tial attributes. But the question occurs to him, how does he know the reality of matter ? And he solved it thus : Because he has a natural impulse to believe in the objects of his sensations, and God, whose existence he has proved, being perfect in his nature, has guarantied the truth ot their testimony. Here then, is the starting-point in natural philosophy — God and matter. And as mat- ter and motion are, to his apprehension, the only phenomena in the physical world, in ac- cordance with his doctrine just now proved, that the most perfect kind of science is that of effects deduced from their causes, he says, " give me matter and motion and I will ex- plain the universe :" and he accordingly ex- THE BACONIAN PHILOSOPHY. 227 plains all material phenomena by the applica- tion of mechanics based upon geometry, ma- king God the prime mover of the universe, and the cause of all material phenomena. In this analysis of the Cartesian philoso- phy, in which we have endeavored to present the fundamental conceptions of that philoso- phy in their true relations and logical order, without any reference to the order in which they stand in the writings of Des Cartes, it is evident that the method is a priori — that it begins with an argument at all its salient points — that psychology is made the founda- tion of every truth, and that the very first truth in this is established by an argument. And what a miserable tissue of sophistry is the whole pretended argument; resting, as it and every other a priori argument must, upon mere assumptions mistaken for innate ideas or principles. The theory of innate ideas and the a priori method of investiga- tion are correlative systems of error. Each is necessary to support the other. And they have been the great fountains from which have flowed copious streams of error into 228 THE BACONIAN PHILOSOPHY. every department of human knowledge. For psychology is the foundation of all human knowledge — is the centre around which every science revolves — is the light in which all other sciences are seen ; and in proportion as this light is true or false, is the correctness of all our opinions upon the great subjects of human thought. Having now established the point, both by philosophical analysis and historical fact, that the theory of innate ideas and the a priori method of investigation have a logical affinity and a doctrinal identity, and are consequent- ly psychological correlatives, we will next treat of the psychological theory, that all our ideas are founded in experience and are ac- quired through sensation and consciousness, and show 7 that it is the psychological correla- tive of the Baconian method of investigation; and in doing this, we shall trace that method to the first impressions made upon the senses, and evolve the principles which govern every step of the process. The most profound and comprehensive re- mark ever uttered by man in the whole his- THE BACONIAN PHILOSOPHY. 229 tory of philosophy, is the first aphorism of the Novum Organon — " Man as the servant and interpreter of nature, does and under- stands as much as his observations on the or- der of nature, either with regard to things or the mind, permit him, and neither knows nor is capable of more. ?? This proposition throws more light over the mysteries of na- ture than every thing that had been written before. It proclaims the true system of both mental and natural philosophy, and defines the limits and the modes of both the knowl- edge and the power of man. All the rest of the Novum Organon does nothing more than develop the great truth contained in this pro- position. In order to exhibit its full import, we will divide it into the two propositions asserting two kindred but distinct truths, of which it is composed. It speaks of man as the interpreter of nature, and also as the ser- vant of nature. Let us keep these two truths separate ; and consider the proposition, first leaving out what is said of man, as the servant of nature ; and then leaving out what is said of him, as the interpreter of nature. Man, as 20 230 THE BACOXIA.N PHILOSOPHY. the interpreter of nature, understands as much as his observations on the order of nature, ei- ther with regard to things or the mind, per- mit him, and does not know more. . Here, it is declared, that the philosopher is a mere interpreter of nature, and that his knowledge is acquired by the observation of the order of nature, of both things and the mind, and that he does not know more. This proposition then, while it proclaims that both natural and mental philosophy are confined to the obser- vation of the order of nature, the antece- dence and sequence of its phenomena, just as distinctly proclaims the theory of mind, that all our knowledge is founded on experi- ence — that we understand as much as our ob- servations on the order of nature, either with regard to things or the mind, permit, but do not know more. But this exposition does not exhaust the fullness of the proposition ; for it speaks of man as the servant as well as the interpreter of nature, and thus points out the mode and the limit of his power as well as the mode and limit of his knowledge. The mode of his power consists in acting as the THE BACONIAN PHILOSOPHY- 231 servant and not as the master of nature, and the mode of his knowledge consists in his interpreting and not anticipating nature. And here is at once shown the connexion between science and art, and the nature of both of them. Science consists in finding out the laws of nature ; and art, or the pow- er of man, consists in obeying these laws — in serving nature. Here then is evolved, out of the first sentence of the Novum Or- ganon, the psychology or theory of mind as- sumed in the Baconian method of investiga- tion, and which the whole scope and drift of that method make manifest ; that all our knowledge is founded in experience. And thus is at once exhibited the point of affiliation and doctrinal identity between the Baconian method of investigation and its correlative system of psychology. But we are not left to infer the psychology ol Bscon merely from what he has tacitly as- sumed; for though the chief object of his writ- ings was to give directions in physical inquir- ies, and to divert the minds of men from me- taphysical speculations about the essence, the 232 THE BACONIAN PHILOSOPHY. eternal reasons and primary causes of things^ and thus, to prevent them from admitting ob- jections against plain experience, founded upon metaphysical notions — as Aristotle and the ancient philosophers had done, according to whose opinions physical science is the ap- plication of metaphysical notions to the ex- planation of the general phenomena of the universe — yet in his Advancement of Learn- ing, he has given a clear view of his theory of mind, and shows that he had a distinct ap- prehension of the great outline of the psychol- ogy which has since been developed by Locke and Reid- "The knowledge of man," says he, "is as the waters, some descending from above, and some springing from beneath ; the one informed by the light of nature, the other inspired by divine revelation. The light of nature consisteth in the notions of the mind, and the reports of the senses. So then according to these two differing illu- minations or originals, knowledge is first of all divided into divinity and philosophy." Ba- con is here speaking of the origin of all hu- man knowledge. He says one kind is deriv- THE BACONIAN PHILOSOPHY. 233 ed from revelation, and the other from the light of nature ; and that the "light of nature consists of the notions of the mind* and the reports of the senses." By the notions of the mind, the whole scope of his writings, their very drift and aim, shows that he means those notions or ideas which are developed in consciousness, and not innate ideas ; and it is plain, that by the reports of the senses, he means the ideas acquired through sensa- tion : though we do not assert that Bacon had apprehended with scientific accuracy these two different sources of knowledge, but merely that he had a general knowledge of them. It is manifest then, that though Bacon laid great stress upon the knowledge derived through the senses, he did not think that sen- sation is the only source of knowledge,as some of the philosophers of the continent of Eu- rope have ignorantly alleged, but that like Locke and Reid he admitted consciousness to be a distinct and equally important source of knowledge. We will now proceed to show that the system of psychology, maintained by Bacon, 234 THE BACONIAN PHILOSOPHY is identical with that of Locke and Reid, indi- cating as we proceed the points of affiliation and doctrinal identity between their system and the Baconian method of investigation, and thus demonstrate that their system is as- sumed in that method. In developing the doctrines of Locke and Reid, we shall not so much follow in their tracks, as pursue the train of our own thoughts : neither shall we stop short at the limits to which they have developed their doctrines, but will give to them more scien- tific completeness than they possess as devel- oped by themselves, by filling up, with logical concatenations, the chasms which lie between the doctrines and their correlative method of investigation, and by modifying any doctrine which they have expressed with too much latitude or expressed imperfectly, so as to make them harmonize in a system. It was the signal glory of Locke to estab- lish the true theory of the origin of our ideas ; and thus to solve the problem which lies at the very threshold of psychology. The the- ory of innate ideas which we have already ex- the baconja:* philosophy, 235 hibited, had prevailed generally throughout the whole history of philosophy. This theo- ry Locke overthrew, just as Bacon had done its correlative method of investigation, and showed how all our ideas originate.* In com- mencing his strictures upon the theory of in- nate ideas he says : a It is an established o- pinion amongst some men, that there are in the understanding certain innate principles, some primary notions, momu ew^, characters, as it were stamped upon the mind of man, which the soul receives in its very first being, and brings into the world w T ith it. ;? He then se- *Note. — We do not mean that Locke has shown correctly in every instance, how our notions have originated ; but that he has shown, that they are all acquir- ed through experience and are not an original furniture of the mind. Can any one doubt, for example, how the notions of colours and sounds are acquired, when they consider that persons who have not the senses of sight and hearing cannot by any means whatever acquire these notions ? They must see at once that these notions are acquired through the senses of sight and hearing. Locke has shown that all other notions of the external world are acquired in a similar way ; though his explanation of some instances may be erroneous. Neither does it detract from the truth of Locke's indication of the sources of these notions, that he has not chosen the most appropriate terms to express them, viz : sensation and reflection. The last is the term which has been mostly con- sidered erroneous. Consciousness has been, and we concur in the opinion, considered as indicating more exactly the source of one class of our ideas. But this precision, though important in scientific accuracy, does not detract from the truth of the solution which Locke has given of the problem of the origin of our ideas. It is a pitiful criticism upon a" great philosophical discovery, to dwell upon a mere inaccuracy in definition ; though certainly, the inaccu- racy ought to be pointed out. 236 THE BACONIAN' PHILOSOPHY. ilects the following propositions as "having the most allowed title to innate " principles, namely :— " Whatsoever is, is; and It is impos- sible for the same thing to be, and not to be. " He then argues that these principles are not so much as known to the greater part of man- kind, and are therefore not innate. " For, first, it is evident, that all children and idiots have not the least apprehension or thought of them ; and the want of that is enough to destroy that universal assent, which must needs be the necessary concomitant of all in- nate truths : it seeming to me near a contra- diction to say, that there are truths imprinted on the soul which it perceives or under- stands not ; imprinting, if it signify anything, being nothing else, but the making certain truths to be perceived. For to imprint any- thing on the mind, without the mind's per- ceiving it, seems to me hardly intelligible. If, therefore, children and idiots have souls, have minds,with those impressions upon them, they must unavoidably perceive them, and necessarily know and assent to these truths ; which, since they do not, it is evident that THE BACONIAN PHILOSOPHY. 237 there are no such impressions. No proposi- tion can be said to be in the mind, which it never yet knew, which it was never yet con- scious of. " To the argument which had been frequently used by the advocates of the doctrine of innate ideas, that men know these innate principles, as soon as they come to the use of reason, he replies : "But how can those men think the use of reason necessary, to discover principles that are supposed in- nate, when reason, (if we may believe them,) is nothing else but the faculty of deducing unknown truths from principles or proposi- tions that are already known ! We may as well think the use of reason necessary to make our eyes discover visible objeets, as that there should be need of reason, or the exer- cise thereof, to make the understanding see what is originally engraven on it, and cannot be in the understanding before it is perceived by it. " After showing that the fact that those propositions are assented to, as soon as proposed and understood, does not prove them innate, and after deducing a variety of other arguments against the doctrine of in- 238 THE BACONIAN PHILOSOPHY. nate ideas or principles, he says : " I say next that these two general propositions are not the truths that first possess the minds of child- ren ; nor are antecedent to all acquired and adventitious notions ; which if they were in- nate, they must needs be. The child certain- ly knows, that the nurse that feeds it, is nei- ther the cat it plays with, nor the blackamoor it is afraid of; that the wormseed or mustard it refuses, is not the apple or sugar it cries for ; this it is certainly and undoubtedly assur- ed of : but will any one say, it is by virtue of this principle, that it is impossible for the same thing to be, and not to be, that it so firmly assents to these and other parts of its knowledge ? Or that the child has any no- tion or apprehension of that proposition, at an age, wherein yet it is plain, it knows a great many other truths?" By this train of reasoning, Locke has" utterly overthrown the theory of innate ideas. This he does in the first book of his work on the human under- standing. And in the second book, he shows the true theory of the origin of ideas or of human knowledge. THE BACONIAN PHILOSOPHY. 239 "Let us," says he, "then suppose the mind to be as we say white paper, void of all char- acters, without any ideas ; how comes it to be furnished ? Whence comes it by that vast store which the busy and boundless fancy of man has painted on it with almost endless va- riety ? Whence has it all the materials of reason and knowledge ? To this I answer, in one word, from experience; in that all our knowledge is founded, and from that it ultima- tely derives itself. Our observation employed either about external sensible objects, or about the internal operations of our minds, perceiv- ed and reflected on by ourselves, is that which supplies our understandings with all the mate- rials of thinking. These two are the fountains of knowledge, from whence all the ideas we have or can naturally have, do spring." Such is Locke's theory of the origin of human knowledge — it is all founded on experience. It has often been urged as an objection to this theory of Locke, that there are certain fundamental ideas which are necessarily as- sumed in the very conception of other ideas, which if derived from experience, could not 240 THE BACOXIAN PHILOSOPHY. have come into the mind, before the ideas in the very conception of which they are assum- ed ; and that consequently, these fundamen- tal ideas, are a priori conceptions of the rea- son. Nothing can be more erroneous than this objection. It is founded upon an entire misconception of the whole process, by which knowledge is acquired. It assumes, that the mind acquires one idea at a time ; whereas this is impossible. When an object is pre- sented to the senses, for example, we not only get an idea of the object, but we also get an idea of existence and unity and other ideas. e * Existence and unity (says Locke,) are two ideas, that are suggested to the un- derstanding, by every object without and every idea within." Now, according to the reasoning of the objection which we are con- sidering ; the ideas of existence and unity, are a priori conceptions. But if it be asked, whe- ther the mind has the ideas of existence and unity before it has the idea of the object which suggests them, and which cannot be appre- hended without assuming them, it surely can- not be answered in the affirmative. If then, it THE BACONIAN PHILOSOPHY. 241 cannot be answered in the affirmative these ideas are not innate, and it is sheer trifling, to call them a priori conceptions, by way of distinguishing them from ideas acquir- ed by experience. Because these ideas are after experience, and are ideas accompanying the idea of the object which has suggested them in experience. The ideas are tied to- gether. They are related to each other, and cannot be conceived except under their rela- tions. And moreover, the ideas are not all brought out in equal distinctness in the first spontaneous action of the mind : but are af- terwards evolved by reflection. The mind does not acquire one idea at a time, any- more than the eyes see one object at a time. Nothing is ever perceived by itself, but must be perceived in its relations to its concomi- tant ideas. It is only by abstraction, after ideas are acquired, that we can isolate them in conception. But in acquiring them, they are always acquired under relations — are al- ways conceived in connection with others. And when, we analyze the idea of an object, it is found that the idea is not formed at once. 21 242 THE BACONIAN PHILOSOPHY. Impressions corresponding with every part of the object^ are made upon the mind, and the whole are combined into an idea of the object. What is called perception,, is a com- pound process — a sort of analytico-synthet- ical process; and the result is multiplicity in unity. Aristotle seems to have had some apprehension of this truth ; for as well as we recollect^, he somewhere calls perception an obscure synthesis. And let any one reflect for a moment on the operation of his mind, and he will at once see, that in the process of perceiving an object, the ideas of existence and unity do not come first into the mind : and yet in analyzing the idea of the object, we see that these ideas are necessarily as- sumed in it. The reasoning relative to these ideas, will hold good against all those which are called a priori conceptions, because the a priori character is ascribed to all of them on account of the fact that they are necessarily assumed in other ideas, before which they could not have come into the mind, if they be acquired by experience. We will there- fore, proceed to show the real origin of the chief of those which are so called. THE BACONIAN PHILOSOPHY. 243 The ideas of time, space and cause are the chief of those which have been said to have an a priori origin. Now, we think it is clear that the first and the last are acquired through the impressions made in consciousness from the mind's own states and acts, and that the other is acquired by external perception. By contemplating the operation of our own fac- ulties, and noting the succession of thoughts, the idea of time is suggested by the lapse in- tervening between the thoughts, as well as between our mental states at the beginning and the end of the process. The interval seen between objects certainly gives us the idea of space. And that things exist in space, is a matter of direct perception ; and space is perceived to be as much of a reality, as the things which exist in it. To deny that space is a reality, and to say, that " It is a thing which being nothing in itself, exists only that other things may exist in it, ?; is nonsense. So, by contemplating the operation of the at- tention and the will in controuling our men- tal operations, we acquire the idea of men- tal power. By considering the effort by 244 THE BACONIAN PHILOSOPHY which we put our limbs in motion we acquire the idea of mechanical force ; and by reflect- ing on the changes which are produced by both the mental power in the current of thought, and by mechanical force in matter, the abstract conception of cause is suggested to us. By the idea ol cause thus acquired from the surest source of experience, our own consciousness, we invariably assign a cause for the changes which take place in the material world. And by the experience of our own intentions as capable of being carri- ed into execution, by mechanical contrivan- ces, we come at the conception of final cause or design as manifested in the machinery of every part of creation. Such then appears to be the origin of these fundamental ideas. They are all founded in experience. Another objection to Locke's theory is that necessary and universal truths cannot be foun- ded in experience. The most prominent of these truths, on account of its great import- ance in our philosophical reasonings, is the proposition : — " Every thing which begins to exist, must have a cause." Now, this truth THE BACONIAN PHILOSOPHY. 245 is certainly not innate knowledge. For all the ideas, Ct existence/ 5 " beginning/ 5 iC cause/' &,c, embraced in it, are derived from expe- rience ; and the proposition merely express- es a relation between them and affirms it to be a necessary one. To say then, that we have knowledge of the relations between things of which we have no ideas at all, as we must do, if we say that we have innate knowledge of the proposition in question, and yet that the ideas embraced in it are ac- quired by experience, is nonsense. The fact that the relation is a necessary one, does not prove that it is not derived from experience. The idea of necessity as well as the idea of contingency belongs to the province of expe- rience. The relations between physical things are contingent — there is no necessary relation between any particular cause and effect, any two physical facts, as far as we know ; and therefore experience does not justify us in saying that there is any such necessary rela- tion : and the philosophy of experience does not teach any such doctrine. Physical phi- losophy does not inquire into causation, but 21* 246 THE BACONIAN PHILOSOPHY. into constant succession — not into efficient causes, but into the laws which regulate the succession of phenomena. Here then every thing is contingent. But the proposition, which we are examining,belongs to a different department of thought. It belongs to meta- physics and not to physics. It is not, let it be observed, a general proposition embracing by way of generalization, all the particular in- stances of relation between physical causes and effects ; and affirming that each particu- lar effect is necessarily produced by the par- ticular fact which precedes it. It is higher up in the inquiry into the constitution of na- ture. It is at a point, where physics cease to answer our interrogatories. It is at a step, where other ideas besides those furnished by matter, must intervene to resolve the * prob- lems. Ideas furnished from the psychologi- cal world, the idea of cause evolved in con- sciousness, must come to our aid in the inqui- ry ; for physical nature cannot be explained without the intervention of these ideas. And thus we are lifted up above physics, but still we are on the basis of experience within the THE BACOMAN philosophy. 247 province of metaphysics. We have gotten from experience in the physical world, the idea that things begin to exist, and from ex- perience in the psychological world, the idea of cause; and we merely affirm the relation which experience tells us must exist between them. The necessity of the relation is forced upon us, by the contradictions, absurdities and impossibilities to which the contrary doc- trine would lead. The relation is not neces- sary in the same manner, that the three angles of a triangle are equal to two right angles. This conclusion is necessitated by the very laws of thought, upon the percep- tion of the relations involved in the proposi- tion, the two sides of the equation being identical truths expressed in different forms, the same quantity being stated in the form of a triangle and also in the form of two right angles. We do not therefore, let it be observed, in sustaining our doctrine, fall into the error of Condillac that,
