ELLIS, PRINTER, 141 FRANKLIN STREET, BOSTON. eRe AGEs THE two courses of lectures included in this volume are those repeatedly given by their author while he held the position of Lecturer on Theology and Ethics in the Meadville Theological School. The lectures on the “Postulates of Revelation” were last delivered in the spring of 1891; and their delivery was, as it happened, the last work of his life. Of this course, the last two lectures were also included among those given at the Lowell Institute in Boston, in 1870, on the “ Natural Sources of Religious Knowledge.” Though they repeat some points of the earlier lectures, they are inserted in this place, partly because they were sometimes used in connection with the others, but mainly because they treat one or two topics more fully, and give a certain complete- ness to the expression of the author’s thought. Espe- cially characteristic and valuable are some portions of the chapter on “ Authority and Influence.” | It should be remembered, however, that these two lect- ures do not appear to have been lately revised by Dr. Hill, and that there may therefore occur in them some iV PREFACE views, or forms of expression, which, after twenty years, he would have wished to modify. The manuscripts of the other lectures show that he made frequent additions and erasures,— changes which, however, usually serve rather to illustrate or apply his thought than to affect its substance. Ten chapters of the ‘ Postulates of Reve- lation” were published in the Unitarian Review during the years 1885-87; and they form the only portion of the book which has had the advantage of the author’s revision. These chapters retain here the form in which they were originally printed, except that the style of direct address has been restored, as well as, in a few in- stances, an apposite figure or illustration. The titles of chapters have also, in a few instances, been modified or restored. The remaining lectures have been changed as little as possible. I have believed that the friends of Dr. Hill, and certainly those who listened to these lectures, would prefer to have this book — which may be regarded as in some sense a memorial volume — retain as much as might be of the flavor of his personality. To this end, inci- dental explanations, personal opinions, the frequent happy use of current discussions, the special shaping of his theme to the character of his auditory,—more than all, the many bits of intellectual autobiography which gave added clearness and zest in the hearing,— may, perhaps, be welcomed also by the readers of these lectures. Their PREFACE Vv interest would be much increased doubtless, too, if it were possible to recall more of the wealth of literary or scientific anecdote, and the frequent statement of per- sonal observation and experience, which the _ lecturer poured forth freely from apparently inexhaustible stores, and which often formed a delightful running commentary upon the severer discussions of the text. For the same reason, I have seldom changed the passages in which he sought, from year to year, to utilize current aspects of ethical or religious discussion, or to meet the mental posture and needs of those before him. While such para- graphs may sometimes break the continuity of the argu- ment, or give undue emphasis to some passing phase of thought, they yet have a biographical interest which has seemed to warrant their retention. So, too, the repeti- tion incident to spoken discourse, and to the discussion in successive courses of allied and in part coincident themes, and the summaries found at the beginning of most chapters, and sometimes at the end, however super- fluous to the scholar, will probably be found helpful to the average student and the general reader. These lectures contain in completer form the leading views of the author on the topics discussed in a series of articles in the Bzbliotheca Sacra — reprinted in “ The Nat- ural Sources of Religious Knowledge’ —and in the little work called “‘Geometry and Faith.” That they form a valuable contribution to the study of the grounds of relig- vi PREFACE ion and ethics is the judgment of many who have heard or read them. Few have brought to this discussion so large and varied knowledge, such comprehensive grasp of the principles of science and the laws of the human mind, an insight so keen, a judgment so well trained and saga- cious, and a spirit at once so receptive, so impartial, and so reverent. To the large intelligence of the great ob- server and the fearless thinker, Dr. Hill joined the enthu- siasm of the unceasing seeker for truth, and the higher wisdom of the pure in heart. To many of those who knew him, the opinion will not seem extravagant that for intellectual strength, wealth and variety of acquirements, and the vigor and justness of his thought, Dr. Hill had very few equals and fewer superiors among the men of his time. He would hardly have failed to achieve dis- tinction as a mathematician, a naturalist, a psychologist or metaphysician, even beyond that which he attained as an educator and theologian. Had his literary faculty equalled his mental power and the wide ranges of his knowledge, I know not what American writer would have excelled him in exposition of his chosen themes, It is probable that this breadth and fulness of knowl- edge have removed his writings somewhat from popular sympathies, and prevented his thought from being valued at its inherent worth. His treatment even of familiar themes often presupposed scientific and mathematical knowledge that is far from being universal. Few, even PREFACE Vii of those who regarded themselves disciples of the scien- tific method, were prepared to appreciate the familiar handling and far following of the facts and theories of science, in whose pursuit and companionship he took such delight. His hearers, even among theological students, did not always find it easy to realize the world of mathe- matical forms, whose harmonies he so clearly perceived, and in which he moved with such ease and secure footing. Possibly, even, some readers of these lectures will be ready to accord with Matthew Arnold’s suggestion, that for the average man a little mathematics goes a great way. A. more serious lack of sympathy between Dr. Hill and the scientific and religious fellowships to which he belonged grew, doubtless, from his lack of conviction as to the prevailing current theories of evolution. A warm friend and disciple of Agassiz, he shared that eminent naturalist’s objections to the Darwinian doctrine of the genetic development of species; and was utterly sceptical concerning natural selection as a main causal agency in the unfolding of the cosmic order and the mounting forms of life. To him the universe was manifestly the sphere of purposive thought; and he counted it unscientific to substitute unconscious process for intelligent directive Power. Darwinism was to him as unphilosophical as unproved. But his opposition was mainly to the agnostic inferences drawn from it by many of its advocates, who Vill PREFACE disowned all teleological causation, and to whom, at first, as one of them has lately said, “it seemed to begin and end only in materialism.’”’ It will be seen by the readers of these lectures that the methods Dr. Hill employed to refute this conclusion are largely those approved, in recent discussions, by eminent evolutionists themselves; and it is clear that his results as to the religious implications of science are much more consonant with the tendencies and spirit of contemporary scientific thought than they were when first advanced a generation ago. On the other hand, he soon came to the conviction, expressed in these pages, that theories of evolution are questions of purely scientific interest, by the acceptance or rejection of which the basis of religion will remain essentially un- affected. While these lectures aim to establish a basis for Chris- tian theology and ethics, they include a survey of the whole field of natural religion, and deal broadly with the grounds and implications of theism, as found in the uni- verse and in human nature. Dr. Hill was a convinced and devout Christian disciple; and he held this posture in fearless loyalty to the uttermost results of science and the profoundest investigations of right reason. The title of his volume of sermons, ‘“‘ Jesus, the Interpreter of Nature,” indicates his assured conviction of the essential harmony of Christianity with natural and universal relig- ion. Readers of these lectures will find in them nothing PREFACE iX of the belittling, and even contempt, of reason which must seriously qualify our admiration of certain recent brilliant defences of religion, and limit their service in re-establishing confidence in the grounds of faith. Dr, Hill’s central reliance on the moral and religious nature of man, as the rational and final witness to spiritual reality, lifted him above all anxieties as to the survival of ethical convictions and devout sentiments, and disengaged his interest from special forms of theological argument and Christian dogma. For instance, his treatment of final causes shows that the defence of teleology is not necessarily connected, and so far as he is concerned never has been connected, with the crude anthropomorphic form it bears in the caricatures of its assailants. It is interesting, also, to observe that, like several other leading defenders of spiritual ethics,—like Dr. William B. Carpenter and James Martineau,— Dr. Hill began as an advocate of necessity and utilitarianism, and like them early abandoned this position. That this has happened so frequently among minds of the first order, in the face of the wide-spread trend of evolutionary ethics in the opposite direction for the last generation, is, perhaps, as remarkable a testimony to the inextinguishable conviction of moral freedom, as the more religious interpretation of nature and science that is happily coming to prevail, and especially the recent notable instances of return from scepticism to faith, are persuasive evidences of the failure X PREFACE of concurrent agnostic theories, and heralds of a brighter day of rational conviction and religious trust. The dawning of that better day the former associates and pupils of Dr. Hill have believed that the publication of these lectures might contribute to advance. It has been a grateful service to superintend their publication, since increasing familiarity with them has but constantly deepened the lifelong sense of obligation and reverence for the author’s thought and character.

The feeling may be a mere impulse, selfish or unselfish. It may be a sense of obli- gation, of the constraint of duty, or the constraint of necessity. It may lie between these extremes. But the general truth embraces all these cases. The general proposition is that every action and every course of action is prompted by a more or less permanent state of feeling or desire, in the shape of taste, inclination, aversion, senti- ment of honor, friendship, ambition, sense of obligation or duty,— whatever be the motive toa voluntary action, it acts through feeling. The preacher who would mould character and lead men to right courses of action must therefore awaken in men some sort of feeling, some sentiment or emotion which will prompt to the desired course of action. None of the good works of the Christian Church are accom- plished by men who have no motives or feelings, good or bad, which lead them to engage in them. So far, therefore, those are undoubtedly right who say that a re- ligious character and religious life consist in a virtuous course of action, a life of usefulness to men, undertaken from good motives, prompted by right feelings; and that right feelings, holy and kind affections, being the springs 4 POSTULATES OF REVELATION of all right endeavors, are to receive the earnest attention of the Christian Church and of the Christian preacher, as essential foundations of the superstructure of benevolent action. Every voluntary action, every true volition, is prompted by something which has the nature of a feeling; that is, a desire, an aversion, a cherished conviction. The Church had for many centuries exalted right opin- ions so highly that many Christians were led to consider orthodoxy of incomparably more value than morality. Now, for fifty years, we have had moral character exalted so highly that many Christians appear to be forgetting that character is influenced and modified by belief. Character is of vastly more consequence than creed. Nevertheless, character is greatly influenced by creed. There are forms of intellectual belief which directly discourage and under- value all attempts to perfect holiness. There are other forms which are a direct stimulus and help to right endeavor. The will is prompted by feeling: feeling depends upon our view of the situation. Those who undervalue Christian doctrine, and say that it is no matter what a man believes, if his heart is only right, fall into the error of supposing that no form of belief can have any injurious effect on the heart. But we may go further. Every feeling, whatever may be its form, is accompanied by, and rests upon, a belief. The most foolish passion, the most purely instinctive aversion, not only blinds the judgment and misleads be- lief; it was accompanied by an error of belief from the beginning of its manifestation ; and the only way in which an adult ever learns to overcome foolish fondness and foolish aversions (which, if not innate, are sometimes con- nate) is by first disabusing himself of the foolish fancies THE UNSEEN ‘REAL 5 connected with his feeling. And, if this be so in regard to these extreme cases, much more is it so with regard to actions in general. It is idle for men to say that the Christian preacher should confine himself to the domain of feeling and action. As action implies feeling,— and, in general, feeling must be aroused in order to produce action,— so feeling implies belief; and, in general, a cer- tain belief must be produced before the feeling can be aroused. In other words, men will not generally feel right about a matter until they take the right view of the matter. The Christian preacher will not induce his peo- ple to do that which he desires, unless he makes them also desirous of doing the same thing. And, although this awakening of the right desire is largely to be accom- plished by the contagion of sympathy, by the contact of living soul with living soul, yet it cannot be accomplished even so, unless it be preceded or accompanied by a per- suasion to look at the desirable things in the right light, to see and understand the truth concerning them. Christian preaching must therefore deal with truth, with doctrine. It cannot effect anything in the world if it ignores truth, if it follows the advice so frequently thrust upon it during the last few decades, and confines itself to religious aspiration and feeling, to the sense of honor and the hope of usefulness. All these sentiments imply foundations of truth, imply belief or doctrine. Men may, it is true, professedly deny the underlying truth, and still retain the feeling. But this is simply be- cause in their professed metaphysic they are doing un- conscious wrong to their own convictions, precisely as every believer in philosophical necessity admits that he practically believes in freedom as much as the man 6 POSTULATES OF REVELATION professedly believing in free will. Men may thus build secretly on foundations of whose existence they are not aware. They do not look below the surface, perhaps think their edifice stands independent of the rock be- neath. But, if the earthquake shakes the rock, their build- ing totters; and, if the rock falls into a subterraneous cave, their edifice follows. In other words, a man may hold verbally very foolish theories concerning the great sub- strata of morality and religion, and yet live a good life. But, if you really take out of his heart the deep convictions on which right actions justify themselves to reason, then you can no longer trust him when it comes to a real trial of his integrity. Strip Christianity of everything that can by the utmost rationalist be considered an accretion or a superfluity, and you still find that Jesus came “to bear testimony to the truth’”; and that, “whatever be’ the date “of ‘thes Pp aupen Gospel, that Gospel does not misrepresent the spirit of the great Teacher when it reports him as saying, “If ye con- tinue in my word, ye will be truly my disciples; and ye will know the truth, and the truth will make you free.” That truth is to be found not only in an acknowledgment of Christ’s truthfulness, but in the acknowledgment that he gave true teaching concerning God and duty and im- mortality. But, as he was teaching Jews, who had for centuries been a nation of believers in God, he takes for granted that his hearers accept this truth, that there is one God, the Father of all, and that our duty toward him is the highest duty. If, on the other hand, instead of reducing Christianity to its lowest terms, we enrich it with all the precious doc- trines concerning Jesus, his offices and functions, which THE UNSEEN REAL fé the cooler understanding will permit us to accept from among the stores of Christian thought in past ages, we shall all the more need to admit the truths which he im- plied in his teaching, and took for granted that the Jews would admit. I have been for many years accustomed to call these truths the postulates of revelation. Deny them,—that is, really and in the heart deny them,—and you deny the possibility of a revelation in any ordinary sense of the word. The morality of Jesus, which, confessedly, even on the lowest possible view of his authority, is the purest and best moral teaching extant, is built on religious founda- tions. It is the sublimated essence of all the Jewish morality, freed from the errors and narrowness of that earlier religion. It demands love and good will toward all men, because all are children of the same Father. It asks us to show mercy, that we may obtain METCy. ELCetS reproduced admirably in Paul’s exhortation, “Be ye imi- tators of God, as dear children.”’ But, take away from a man all faith in the being of God, lead him to the thoroughly agnostic position of deny- ing that there are any evidences whatever of wisdom or love ruling the operations of Nature, and you render it impossible for him to be a Christian believer, even in the sense of accepting Christ’s teaching,— more impossible, if I may be allowed the expression, to believe that Jesus is the Christ, that he was sent, that he testified of what he knew. Even if, therefore, it would be to no profit for Christian believers in general to discuss these postulates of revela- tion,—and in ordinary preaching to men as they come, it may even be far better to avoid such themes, and to take 8 POSTULATES OF REVELATION for granted that all the congregation believe in one God, the Father Almighty, Maker of heaven and earth, All- wise, All-holy, All-good,— yet it is well also for the Chris- tian preacher to be ready on occasion to fortify those whose faith is assailed by agnostic speculations, those who feel the chilling atmosphere which breathes from so much of our modern literature, aiming to be _half- scientific,— to fortify them by showing that he, too, has heard of the theories which deny the great postulates of revelation, and has examined those theories sufficiently to say with certainty that, whenever they conflict with these postulates, it is because the theory is either false or partly false, and needs correction; and that the postulates of revelation will stand as immovable as the axioms of geometry. Let us, therefore, endeavor to discover the real origin of these conceptions in the human mind, and to estimate their basis and validity as a foundation for a religious faith. Of course, we cannot expect to arrive at a perfect unanimity of opinion. Native differences of mental con- stitution and differences of early education will infallibly lead us to take different views on every subject. Even an algebraical equation or an axiom of geometry presents different phases to different minds. But there is always hope, if we are candid and truth-seeking, that we can come to a substantial agreement. The body of mathematical truth is agreed upon by all; and the unity of belief upon morality and religion will, after full and earnest discus- sion, become equally general. Let us begin, then, by inquiring what are the primal truths of consciousness, It has always seemed to me that the first intellectual act is the recognition of physical THE UNSEEN REAL 9 motion; which is virtually a recognition of the existence of space and time. The first distinctly intellectual con- ception in the child is probably composed of three simul- taneous elements not separated in the act, but then inex- tricably fused. These are the consciousness of self, the consciousness of the motion of its own limbs and of the resistance to motion. But, as motion involves space and time, it may be said that this first probable intellectual act of the human being involves the perception of the existence of self, of matter, of space, and of time. In this first act of the intellect the grand problem of ontology is presented to it,—the high mystery of space, time, and spirit. The moment that the child is born we know by obser- vation that its intellectual activity concerning geometrical figure and concerning motion very far exceeds all its other intellectual activities. In a few weeks it learns to distinguish human beings at sight, in a few months it recognizes individuals. Before five years have passed it recognizes every kind of material object in engravings and photographs, and of course can do it only by the slight similarity of figure in the picture to the natural object. I admit that the child five years old has learned ten thousand other things. Jouffroy speaks well when he says that a man learns far more in the first five years of life than in any subsequent five. But I maintain that, in this vast amount of knowledge and of intellectual skill acquired in the first five years of life, by far the greater part is included in the knowledge of geometrical forms and of modes of motion. And modern science in its patient search after the unity of law has arrived at the grand result that probably IO POSTULATES OF REVELATION all physical phenomena are merely modes of motion. The five senses by which we take cognizance of the exist- ence and attributes of matter are capable of nothing further than the perception of motion or the resistance to motion. Touch, if we include in it the sense of muscular contraction, recognizes the motion of masses of a finite size, and the resistance to it. It also recognizes tempera- ture, which Bacon from a false induction, Huyghens and Rumford from correct reasoning, showed to be merely a mode of molecular motion. Touch further distinguishes between rigidity, plasticity, fluidity, and the gaseous con- dition ; and these have been reduced by modern science to difference in the movements of the atomic constituency of matter. Hearing is but the recognition of a certain tremor or vibration produced in the nerves of the ear by motions of the air, or of solid bodies in contact with the solid frame- work of the head. Sight is in the same way the recognition of certain tremors or vibrations in the optic nerve, referred to the vibrations of an ether by the almost unanimous judgment of modern men of science. Taste and smell are not so readily shown to be the cog- nition of motion. They apparently lay hold of chemical differences and identities. But what are chemical differ- ences and identities? They are referable in all instances to other standards than those of taste and smell. They are always capable, by proper manipulation, of being made manifest to sight and touch. Even the chemical forces can be weighed against the weight of the materials, and thus shown to be merely new manifestations of mechan- ical force; z.2., of the force that produces motion. Thus THE UNSEEN REAL II it is, in the view of science, highly probable that the elec- tric, magnetic, and chemical phenomena, since they are the result of forces which can be weighed against gravity and measured by motion (so many pounds, so many feet in a second), are themselves simply modes of motion. But what is physical motion? It is the passage of matter through space in time. It occupies time and _ space. And what is matter? It is that which is capable of mani- festing motion. We cannot get behind that. Push and drive your analysis as you may, you come to sensible properties which are shown by modern scientific experi- ment to be merely modes of motion in the molecules, or in the atoms. And what is an atom? All we know of it is that at a certain point in space there is a series of mani- festations of power repelling or attracting other points in certain directions. Make it a vortex ring in a homo- geneous, frictionless fluid, and you only drive the mystery further back. You create a finer kind of matter, to be defined in a similar way. What the thing itself is eludes our grasp. We only get its action, which is the manifes- tation of the force that produces or resists motion. All the universe of matter is thus reduced for us to a display of motion. This motion is communicated to our nervous system; and, when the. nervous system receives this motion and transmits it to the brain, we perceive it. We do not, however, recognize it as motion unless it pro- duce a finite motion in our nerves, passing sensibly from one part of the retina to another, changing in intensity within a finite time, etc. If it be infinite to us,—z.e,, moving all parts of our systems uniformly,— it is not rec- ognized at all. On the other hand, if the motion be in- finitesimal to us, we do not recognize it as motion, but call it sound, warmth, color, smell, and the like. 12 POSTULATES, OF REVELATION How does the motion of the nervous system produce these changes in our consciousness? We do not know, nor can we conceive any mode while we are living in the body by which we can know. We are shut up simply to these conclusions: that we know the external universe, including our own bodies, primarily and directly, only through sensations; and that sensations are produced only through peculiar motions of the nervous system, communicated from motions of the outward world. But this movement of the outward world is, for us and as far as our knowledge can at present extend, a phenomenon of time and space only, producing changes of conscious- ness in us. The conscious self, and something not our- selves, as inscrutable as our self, illustrating for us by mo- tion the laws and relations of space and time,—this is all that is given to us in the simple act of sense-perception. To go higher, the conscious self must, since the content of that consciousness is simply self, and something not self, be aroused to new and higher action than simple sense-perception. It is aroused, first of all, to perceive that the phe- nomenon of motion involves space and time. The eternal and necessary existence of space is the thing which is usually first seen above and beyond sense-perception. We attempt to run out beyond the limits of vision; and we see that space must extend ever beyond. We try to imagine the removal of matter from a certain space, and see that the space itself cannot be removed. The neces- sary and eternal flow of time is usually the next of super- sensible things which is immediately perceived by the mind, The two ideas of space and time are fundamentally distinct, yet one cannot be conceived without the other. THE UNSEEN REAL 13 Space must endure throughout all time; and we can imagine endurance in time only as being throughout all space. Motion takes place in both at once, and they are logically necessary antecedent conditions of motion. But, thirdly, when we study motion in any form, finite or infinitesimal, we perceive that it implies the existence of cause, efficiency, or power. This is a direct vision of that which escapes the senses. Motion is conceivable to us only as the passage of a something which is capable of motion, under pressure of a force capable of producing motion. Yet, as we have already said, when the physicist pursues his conception of an atom and hunts it down to its last analysis, he cannot distinguish it from a mere point in space whence certain forces flow. Even molar motions may therefore be said to be merely the transfer of the centres emanating force from point to point in space. Matter is known to us only as portions of space in which certain forces are manifested. And all forces are supposed by modern scientific men to be one and the same force, producing various modes of motion, as deter- mined by the action of the surrounding points. The two modes of motion, or force- manifestation, which are most widely diffused are elasticity and gravity. I strike a telegraph wire, and the jar courses along it by the elasticity of the iron at the rate of some three miles a second. I fire a cannon, and the sound flies only one- fifth of a mile in a second. But the light of the flash flies nearly a million times as fast. We thus learn that the elasticity of the wire is more than two hundred times as great in proportion to the weight of its molecules as that of air, and that the elasticity of the fluid or gas through which the wave of light is communicated is nearly a trill- I4 POSTULATES OF REVELATION ion (2.é., million million) times as great as that of the air. The immense tension of this elastic force goes beyond the reach of our imagination. The impulse given to it by the flash of the powder flies out at the rate of 186,000 miles a second. And this force, this compression, is omni- present. The most distant star visible to the most power- ful telescope announces to us, by the very fact of its visibility, that the source and the effects of this mighty grasp extend beyond the reach of the telescope. But the force of gravity, if it be communicated through undulations, must move ten million times as fast as light. At least, this is the calculation of Laplace. “If gravity require time for transmission,” he said, “its speed is at least ten million times that of light.’”’ But this would re- quire the universal presence of a fluid at least a hun- dred trillion times as elastic as that in which light moves; that is, a hundred trillion trillion times as elastic as air. We stagger under the conception of the luminiferous ether, a million million times as elastic as air; but, when we are presented with another substance a hundred million million times as elastic as ether, we throw off the burden, it cannot be borne. And we prefer to conceive of gravity as a force acting immediately at a finite distance from a finite mass. The phenomena of elasticity also force us by logical necessity to admit that the atoms (whether we conceive of them in Newton’s fashion as perfectly hard little masses, or in Boscovich’s fashion as mere centres of force, or in the modern fashion as vortex rings) exert force without direct contact. This conclusion will not be affected by any view taken of Leibnitz’s monadology and principle of continuity, being forced upon us by the ex- perimental facts of elasticity. THE UNSEEN REAL 15 The cosmical phenomena also force us to the conclu- sion that the weight of a body is the result of a force exerted upon it by the mass of the earth, without the intervention of any material agency. This power of the cosmical bodies is omnipresent and constant. What Leibnitz meant by saying that the amount of force in the universe is constant I do not know. I have not had the opportunity to examine; but I cannot believe that he meant it in the sense in which it has often been asserted in our own days. There are, however, several senses in which I do not question its truth. First, the elasticity of the ether and its compression are the same in all parts of the universe, and probably the same throughout countless ages,—although of this latter point we have no direct proof. Secondly, when a disturbance is produced in this ether, say, by the passage of an electric spark, the wave spreads in every direction, and, if there be no opaque obstacle, forms the surface of a constantly enlarging sphere. The surface of the sphere constantly enlarging, the amount of motion originally communicated is spread out thinner and thinner. But the total amount remains the same, pro- vided the elasticity is perfect. If not perfect, a part of the motion is retained within the sphere in some other fermen. ‘EFhus, as the elasticity of the air is not perfect, a wave of sound not only spreads out thinner and fainter as it goes, but part of it is lost and left behind in the form of infinitesimal warmth and electrical excitement. What I referred to as a doctrine of conservation which I cannot believe is the assertion that the wave of light or heat which passes out beyond the boundaries of telescopic vision is returned again to us. Of that we have no 16 POSTULATES OF REVELATION proof; and it is even said by some geometers to be mathematically incredible. But, thirdly, the sum of the gravitating power of the cos- mic bodies remains constant. Meteors and comets fall into the sun or upon the earth, and slightly increase their gravitative force. But the increased force is simply the sum of the old forces. And the gravitating power of the earth is the same at all distances. The moon is sixty times as far from the earth’s centre as we are; and it is usually said that gravity there is only z¢50 part as great as it is here. It is true in the sense in which it is meant. When a wave of light has travelled sixty miles, it is spread over 3,600 times as much surface as when it has gone one mile, and only appears z¢o5 part as bright. Yet the total amount of light remains the same. As with this actual force of light undulation, so with the potential force of gravity. The earth actually holds only one moon in her orbit, but is potentially able to attract with the same power any other body coming to the same distance as the moon; and at the moon’s dis- tance there is 3,600 times as much space for bodies to be arrayed. The sum of the power to attract there is there- fore 3,600 times sey; that is, it is the same as at the earth’s surface. Nor, according to the accepted theory of gravitation, could this potential power ever be exhausted by increasing its actual exercise. Let moon upon moon or planet after planet be bowled gently by the side of our earth until she were lost among them, like a gnat in the midst of an innumerable swarm of gnats, and still she would hold her present moon with precisely as firm a hold as at present. 7% We find, then, an omnipresent force of elasticity and an THE UNSEEN REAL 7 omnipresent force of gravity; and all the phenomena of external nature, which at first seemed to be the solid real- ities of the universe, fade, under the searching glance of reason guided by science, into that which religious philos- ophy had long since declared it,— the inscrutable clothing of inscrutable power. That which moves matter without the intervention of matter or material agency is consid- ered magical or spiritual; yet the force of gravity moves matter without the agency of matter. What is it, then, but an omnipresent spiritual power, manifesting itself ? And matter itself is, by the phenomenon of elasticity, and by the nature of nerve-sensation, shown to be a con- geries of points without dimensions, acting on each other without contact, manifesting, by the actual forces dis- played, the presence of almost illimitable powers, poten- tial forces slumbering in those mysterious centres. We turn back to our first consciousness, aroused in sense-perception. We have shown that it gives us, when interrogated sharply, the existence of space, time, and force,— 2.¢., power-producing motion,— but that we fail to get any distinct view of the thing moved. It seems to elude analysis, and vanish into the self-contradiction of a moving point, or the equally difficult conception of forces acting from a centre which has no assignable dimensions, but which is driven from point to point in space, and drives other centres. We now turn to the self side. What is it which thus is conscious of sense-perception? Am I, the me which per- ceives, also a mere mode of motion? No: I do not rec- ognize in myself any direct relation to motion, force, space, and time. I see them without, outside of myself. I trace the external motion into my body, into my ner- 18 POSTULATES OF REVELATION vous system, up to my brain; but I do it by the use of sight, touch, and hearing, and not by self-consciousness. When I turn my mind upon the act of sense-perception, and, attempting to analyze it, come at length to the con- templation of the conscious me, then I become self-con- scious. I feel at once that I have stepped across a wide gulf, the sides of which are separated, to use Hamilton’s expression, by the whole diameter of being. I see myself related to or connected with my body, which is in space and time subject to force, receiving modes of motion, and thereby leading to sensation. But the sensation itself is not a mode of motion nor apprehended by sensation as motion is: it is apprehended by a direct intuition, just as space, time, and force are apprehended. In sense-percep- tion we think that we see matter moving, or hear sounds, or smell odors; and, undoubtedly, the senses do give us trustworthy testimony of the existence of something real, which to our senses is continuously extended. Sharper analysis shows, however, that matter itself is invisible. The eye recognizes modes of motion, the ear other modes, and so on, But no science can destroy the testimony of the internal self, the immediate vision of space, time, force, and sense, or show the possibility that either of these can be a mode of motion. Space is indestructible even in imagination ; so, also, is time ; the existence of force as a cause of external motion can no more be denied than our own existence. Think for a moment of the means by which our great cities are now illuminated. Here is a mass of common cast and wrought iron wrapped with copper wires ; and within it a sphere of similar materials, turning upon a delicately poised axis, so arranged that the friction is practically THE UNSEEN REAL 19 nothing: the smallest child could turn the sphere, which is separated by a blank space of a finger’s breadth on every side from the cast-iron cups in which it turns. Yet a powerful steam-engine is set to rotating this sphere. At first but little steam is requisite to overcome the trifling friction of the axis; but, as the velocity increases, more and more power must be applied, so that at the end of two or three minutes the whole force of the powerful engine is required to turn this little sphere, which at first the smallest child could spin. What, then, becomes of the force of the engine, which goes on laboring hour after hour, putting forth all its strength to accomplish what at first seemed so trifling a task? The answer is that the power of that engine leaps across the space between the sphere and the iron cups, and, being magically converted from the mechanical force of the engine into magnetism and into an electric current, is led from one end of the axis through a long circuit of wire, returning to the other end of the axis. In the course of this long circuit, how- ever, around the streets of the city, it is interrupted at various points, and dispersed in the form of powerful rays of light. Nine-tenths of the power of the steam-engine are thus in the best forms of the dynamo converted into electricity, and the greater part of that electricity con- verted into light. But the agent in transforming this mechanical force of the engine into the continuous cur- rent of electricity through the wire is a finger’s breadth of space, which would act just as well were it as perfect a vacuum as art can make. The connection is through the ether, which is cognizable by not one of the five senses, but shows itself to reason as a fluid without recognizable friction and under tremendous universal pressure. 20 POSTULATES OF REVELATION Still more striking evidences of the reality of the un- seen are furnished by the consideration of organic life, but it would carry us too far from the simplicity of our main line of thought to pursue them. As a single illus- tration of the facts to which we refer, take the heredity which plays so important a part in the theories and specu- lations of modern naturalists. All the plants and animals of the world are produced from seeds and eggs, and these seeds and eggs sprout and hatch into a likeness of both parents. Even those naturalists who suppose that the difference of species has been produced by gradual varia- tion — from a few original types or from one — admit that the variation is usually very slow. For many generations, even for thousands upon thousands, like produces like. What is it in the ovum or ovule which makes it develop into the likeness of the parent? Is it a peculiar arrange- ment of the atoms of which the little globule consists, or is it something inscrutable? Clerk Maxwell argues that the little ova or ovules cannot contain a sufficient number of atoms to admit of all the variety of arrangements requisite to produce the prodigious number of fossil and living species of plants and animals. His argument, from the limits assigned to the size of atoms, becomes doubly strong when we apply it, not to the ovule or ovum, but to that exceedingly minute portion of fluid, filtered through at least two apparently impervious walls, which, in the case of hybrids, is seen to convey to the offspring numer- ous peculiarities of the male parent. All that is really given by the act of sense-perception, apparently revealing to us a world of solid material and complex variety, is the existence of a conscious self, float- ing in boundless space and boundless time, surrounded THE UNSEEN REAL ZI and sustained by boundless power. But these it does give; and the conscious self refuses to be identified with either of the other three, or with any combination of them. The object of stating so fully these first truths of con- sciousness will, I hope, become manifest in the succeed- ing lectures. 1EE THE REALITY OF KNOWLEDGE. In our first lecture we attempted a rough analysis of the contents of consciousness in the first act of simple sense-perception. We found that it contained or implied the existence of the subject self perceiving something external to self, and, at first, of something moving. Next we found that all sense-perception has been proved by modern science to be, in fact, the perception of motion, because all sensible phenomena have been resolved, with great probability, into various modes of motion. On a sharper analysis of the thing moving, it is resolved into manifestations of force in space and time,—three entities which entirely elude the outward senses, and whose being is avouched to us, precisely as our own being is, by an inward perception, or intuition. As we know that we ourselves exist, so and by the same sort of evidence we know the existence of space, time, and force,— immaterial entities seen by the inward eye more clearly, and under- stood more perfectly, than anything seen by the outward eye can be. Outward sense shows the action of forces ; and reason follows up, and shows us that this is all that outward sense can show, Let us now turn to the first of the entities perceived by the inward eye: itis our own conscious self. The conscious self is in philosophy called the subject. It is so difficult \ THE REALITY OF KNOWLEDGE 23 to examine, that the school of Positive Philosophy declare it impossible. As well, says Comte, may a man attempt to look at his own eye as to attempt to look at his own mind. On the other hand, the schools of philosophy wor- thy of the name unite in declaring that the whole field of philosophy lies embosomed in consciousness, and that it is only by an examination of the processes going on within us that we can arrive at any truth worth knowing. There is, however, a great difficulty in analyzing the action of the mind. It is well illustrated by the familiar fact that uncultivated persons are wholly unable to give the real reasons for their daily judgments, even when the judg- ments are sound. This inability, it is true, sometimes proceeds merely from the lack of words in which to for- mulate their knowledge; but it still more frequently arises from a want of skill in cross-examining the wit- nesses of memory, testifying concerning the process by which the judgment was reached. Now, in looking at the conscious self, we depend very largely upon the memory. Comte is right so far as this: that, while the mind is wholly absorbed in some other proc- ess, it cannot also be giving its whole strength to the analysis of that process. We must, in general, remember the process, and, while the memory is still vivid, hold off the subjective process as an object of thought. It re- quires long practice to attain skill in this dissection of a past process; but it requires still greater practice and rarer power to be able to observe the action of the mind while the process is actually going on. The consequence is that very few persons know them- selves, in any emphatic sense of the words. Their fancied knowledge of themselves is only the knowledge of their 24 POSTULATES OF REVELATION own portrait, frequently of a portrait unskilfuily taken. Oliver Wendell Holmes pleasantly describes one of the results of this self-ignorance}; namely, that in every dialogue there are at least six speakers. When, for ex- ample, the Secretary of State has a private interview with the President, there are at least twelve persons present, modifying all that is said: first, the two men themselves in their real character; second, the two officials in their official characters, which will probably differ more or less from the real private character. Here are four. The other eight consist of the estimates or pictures of these four formed by each of the two men; and eight more could easily be described. Passing, however, from these pictures of character, pict- ures of the subject, to the reality, what is the subject, the conscious self? Can it be resolved into either of the four elements which we have already found? Space? Time? Force? Or the guartum quid, which eludes analysis, and makes certain points of space manifest force at certain moments of time? Space and time are at once excluded. The ego, me, or self stands in relation to space and time only through its ability to see them by an inward perception, and to meas- ure them by real or imagined motion. The life or mani- festations of the ego are for the present in time, and even connected with the imagination of space; but the ego itself is conscious of no dependence on either. Neither are its manifestations modes of motion. That they may all be connected, for the present, with modes of motion in the nervous system of the body is very proba- ble, if not fully proved. But this by no means makes them consist of modes of motion. Modes of motion are THE REALITY OF KNOWLEDGE 25 recognizable only through sense-perception : they are out- side the sphere of consciousness. The perception of mo- tion is the immediate perception of the not-me. Modes of consciousness are, on the other hand, recognizable only through consciousness. They are thus absolutely discrete and heterogeneous from motion. Yet there is a large school at the present day of men who follow the lead of Comte and of Herbert Spencer in a fallacious course of reasoning by which they would show that consciousness is only a manifestation of me- chanical force. This argument is stated by Comte some- what in this form :— “Man dies if either deprived of food or if overfed, if either frozen or overheated, if either drowned or over- dried, if deprived of air or over-supplied with oxygen ; and, finally, if a metaphysician were made to stand on his head five minutes, all his eternal realities would become non-existent. Therefore, man is a part of the material universe, and the result of its physical forces.” It is strange that intelligent men should be deceived by such an evidently fallacious argument which confounds the concomitant conditions with the causes of a phenome- non. The fallacy is most readily exposed by a carefully copied parody of the argument which I have given else- where. Here is a mantel clock which, its owner affirms, goes by a spring within. No, says a positivist, that is not so. It will stop if not oiled and it will stop if over- oiled ; it will stop if frozen, it will stop if overheated ; it will stop if plunged under water, it will stop if it be ex- posed to a dry and dusty air; and it will stop in an instant if you turn it upside down. The spring is a con- ceit of your imagination. The clock goes by gravity, 26 POSTULATES OF REVELATION just temperature, proper hygrometric conditions, and a proper feeding with oil. But the owner of the clock knows it has a spring in it; and I know that I have a soul in me. The infinite gulf between the motion of a nerve and the consciousness of a sensation can be bridged by no such loose and careless engineering. The conscious me is no more a part of the body and a result of external agencies than the mainspring of the mantel clock is a part of the train which it drives or a result of the oscillation of the pendulum. What, then, is the conscious me, the subjective sub- ject? It is a guzntum qutd, recognizable only in con- sciousness, just as the guartum quid of matter is recogniz- able only through force producing motion. When matter ceases to exert any force, it ceases to produce even the infinitesimal motions of heat and light, it offers no re- sistance to other matter: it ceases to exist to us; we can- not follow it even in imagination; it has reverted to the abyss of potentiality. So with the conscious subject, if it ceases utterly from consciousness; as, for example, it is supposed, not only by unbelievers in immortality, but by numerous Christians, believers in the sleep of the soul, to cease from consciousness at death, and to lie dormant for centuries after the body has returned to dust. Then, I say, the conscious me ceases to exist to us, and to our thought. We cannot follow it even in imagination. It has reverted to the abyss of potentiality: its resurrection to life cannot be construed to our imagination as other than a new creation, more wonderful than the first, be- cause in that re-creation the soul would come forth with crowded memories of the past. THE REALITY OF KNOWLEDGE 2/7 Consciousness is the distinguishing characteristic of the subject, as motion is of matter, extension of space, duration of time. The ego, or subject, has no finite me- chanical force. Its manifestations and actions cannot be measured in foot pounds. The consumption of phos- phorus may indicate, if you please, the amount of move- ment in the brain; and thus the brain movement be weighed in foot pounds against other motions. But that brain movement is not a measure of consciousness, not even of its amount, and much less of its character and value. A blockhead or a villain may consume as much phosphorus every twenty-four hours as a genius or a saint. Consciousness is measured more nearly by quality than by quantity of brain-work. The finer quality of work may require finer tools; and thus it may be true, as Dr. J. C. Warren thought it, that a man of genius has a brain of finer and more delicate organization. But consciousness is not mere motion, nor is mental action measurable by physical force: it is not the result of the exertion of force, except as we use a description of external nature as a typical expression of the facts of internal consciousness. (And this appears, by the way, to spiritual philosophy to be one of the main uses of external nature; namely, to furnish types whereby to express spiritual things.) P What, then, are the faculties of the ego, as revealed in consciousness? Psychologists of every school have for a century past included them in three,— sight, feeling, thls es By sight we mean the power of perceiving or knowing. This seems the first and fundamental thing in con- sciousness. What is consciousness but knowing, or co- 28 POSTULATES OF REVELATION ordinating knowledge? We have been in the first and in the present lecture asking, What do we see in every conscious moment? taking it for granted that we see. We perceive external sensations, and perceive that they are external. We perceive space and time and motion. We perceive the existence of force. We perceive the existence of cause, a genus of which force is a species. We perceive that we perceive. All these are forms of direct sight, which I give, not as exhausting, but simply as illustrating, the power of direct or immediate percep- tion which I call sight. But we also perceive that we feel. Even sensations are pleasant or unpleasant. It is impossible for us to imagine ourselves in a state of consciousness absolutely devoid of feeling; that is, in which we should neither be pleased nor displeased, contented nor discontented, soothed nor annoyed, interested nor disgusted. Some slight degree of feeling of some kind must accompany every state of consciousness imaginable by us, because some degree has accompanied every state experienced by us. So far as our experience goes, every state of consciousness includes a state of feeling; and a state of absolute indifference is like a state of unstable equi- librium in mechanics, only capable of being maintained for an inappreciable instant. The feelings culminate in desires which are but intensi- fied feelings, and the desires prompt to volition. Will is the highest action of the ego, and the most difficult of analysis. But at every conscious moment we not only are percipient in the intellect and recipient in the heart, but accipient or excipient in the will; that is, we are act- ing or refraining from action. THE REALITY OF KNOWLEDGE 29 The simplest action of the ego is the mere act of atten- tion or refusing attention. In the momentary sphere of consciousness a thousand things present themselves, to the external sense, to bodily sensation, to memory, to imagination, to reason ; and the ego, the proper self within, chooses to which it shall give its principal attention. This power of the mind to concentrate its forces on one part of the sphere of consciousness, and remand the other parts to the abyss of potentiality, differs greatly in differ- ent men; but it is to some extent always present, and is one of the main differences between sanity and insanity. Of course, it is finite in a finite being. If a fly flew into the room, it would of course be in the power of any one of us to withhold attention from it. But if, on the other hand, a hand-grenade with a smoking fuse came in at the window, or a meteoric stone descended through the roof, it would be impossible for any one to refuse attention to it. Limited, however, as the power is, it is nevertheless a real power, and is the grandest faculty of our nature. In that power of directing and concentrating attention lies the first element of success, and of greatness, in what- ever department of thought or action. The second action of the conscious self through will power is the command of the body. Through involun- tary muscular movements the attention of the infant is early called to its being in a body capable of motion. As I said in the first lecture, this is probably the earliest state of consciousness, the consciousness of bodily motion. As the conscious self comes to higher activity, it wills that some of these involuntary motions shall be repeated ; and they are repeated. How, by what agency, the child does not know. Nor does the most thorough student of the 30 POSTULATES ‘OF REVELATION physiological action of the brain and nervous system even to-day know, any better than the infant, how the immeas- urable gulf between consciousness and the material body is spanned. I pronounce the word “speech,” or I write it upon this sheet of paper. The chemist and the mechanic may explain the nature of ink and of my stylographic pen. The anatomist may describe with minute accuracy the movement of every muscle, and show through what nerves the commands come to those muscles. The physiologist may fancy that he can tell from what particular set of nerve-cells the command originated. But not one of them can tell, or will probably ever be able, in this world, to tell how the decision of my will started those nerve-cells to their peculiar action. The will, the conscious self in the act of volition, has no measurable force, no power to be developed into motion. But it has a power to develop the dormant power of the nerve-cells into a motion which, in its turn, shall develop or arouse the dormant power of the muscular fibre. Still more wonderful, this decision of the conscious will decides the direction and amount of force which shall be brought into play by each muscle. How this thing is done we know not. The lower ani- mals perform the same thing, although not in such com- plicated modes. Agassiz opened a snapping tortoise’s egg some weeks before it was ready to hatch; and the young tortoise, although but three-fourths ready for its entrance upon outer life, snapped at the lead-pencil which was brought near it. The Darwinist says that this simply proves that the young tortoise had been practising snap- ping at pencil-points for a million of years, so that the habit was inveterate,— practising, of course, in the person of its fathers. But this spreading of the marvel over a million THE REALITY OF KNOWLEDGE al of years does nothing to diminish its marvellous charac- ter. A good draughtsman sees a figure which is new and striking, or sees a child at play take a new and particu- larly pleasing attitude ; and in a moment he sketches with his pencil a correct outline. The draughtsman knows nothing about the action of his nerve-cells and muscles. He wills that his pencil shall reproduce a new outline, and it does it. The Fuegian Indian, wholly untutored, hears a foreign word, containing, perhaps, sounds which do not occur in his native language, yet he pronounces it accurately at the first effort. All this control of the mind over the body is magic. It cannot be reduced to the nexus of physical causes and effects. It is not a manifestation of force, but is simply a guidance of force. The will does not come under the categories of external nature: itis not a cause, in the physical sense of the word. It lies in the realm of consciousness; and we do not know and cannot imagine the mode in which it reaches over the gulf of separation, and guides the forces of the external world. The materialistic philosophy attempts to make the will simply a part of the nexus of physical causes and effects, and thus to get rid Of the necessity of confessing magic. But the attempt is unsuccessful, because it is impossible to construe to consciousness the proposition that con- sciousness, or any of its modes, is a mode of manifesta- tion of material motion. The two things are separated “by the whole diameter of being”; and the materialistic philosopher is simply beclouding himself with words to which he cannot attach an intelligible sense, when he at- tempts to make them one. | To return to the first faculty,— that of sight,— let us consider for a few moments the question whether we can 32 POSTULATES OF REVELATION depend upon sight. This is the first and most impor- tant point to be settled in philosophy, whether we can trust our own faculties. But it is a question that settles itself, when properly stated. In all departments of human knowledge and of intellectual investigation the solution of a problem is never really possible until the problem is clearly and correctly stated; and the clear, correct state- ment is usually a great step toward the solution. Can we believe what we believe? can we see what we see? can we hear what we hear? The questions answer themselves in the affirmative. To answer in the negative is to deny our own existence, and to deny one’s own ca- pability of denying. Sober philosophy proceeding to that step becomes mad reverie and senseless jargon. We see what we see: the real question is, What do we see? Take as an illustration the act of literal sight with the bodily eye. The new-born child turns his eye toward the window, and sees, let us say, a green tree waving in the wind just outside. He actually sees a something green in motion, and knows that it is not himself. And that is all that he actually sees when in mature life he looks out at the same object, although he may then think he sees that it is a tree of a definite species, size, distance from the house, etc. But these details are inferences, judgments ; and the actual direct sense-perception is simply some- thing of mottled green in motion, not himself, not his own body, but outside his body. This last point, the distin- guishing of sight from vision, is more difficult, but in a sane mind always possible. In fact, the organ of vision, the expansion of the optic nerve, has three functions in connection with the mind (and, mutatis mutandis, what I am about to say of this nerve may be said of every part of THE REALITY OF KNOWLEDGE 33 the nervous system, brain andall). It receives impressions normally from without, which cause sensations ; it receives normally a gentler impression from within, from the men- tal action, and this gives vividness to memory and imagi- nation of sensible things; thirdly, it is capable of abnor- mal excitement through accident or disease, giving rise to pseudo-sensations, to which memory and imagination sometimes lend form, thus producing visions and subjec- tive impressions, as of hearing music, tasting flavors, etc. But these visions are distinguishable by a sound mind from the real normal impressions from without. The sound mind knows that it perceives something green ex- ternal to itself, external even to its own body. What that something is, it judges by inference; but that there is some- thing there is the direct testimony of consciousness, and cannot be denied without opening the door to insanity and turning reason adrift. But it is said that this something may not be at all like our sensation. Of course, it is not: the sensation is a fact of consciousness, the something external is a fact in the external world. Between them there may be a corre- spondence, but there cannot be a similarity. What of it? That does not invalidate the testimony of consciousness that there is something there which produces the sensation which we call the perception of a green color. It is a mere quibble upon words to say the grass is not green. It is precisely like denying that this tuning-fork is E-flat. The fork is not the vibration of the air, much less is the fork the particular musical sensation which vibrations of that particular frequency give to a musical ear. But the fork, if set in vibration, will give vibrations which will pro- duce in a musical ear the sensation called E-flat. There- 34 POSTULATES OF REVELATION fore, the fork is called E-flat. In like manner the leaf of the tree responds in the light of the sun to particular vibra- tions which give to a healthy eye the perception of a color which is called green; and that is all that is meant by saying the leaf is green. The eye does not deceive you. It says that here is something which will produce in every healthy human mind, turning toward it in common day- light, a healthy normal eye, a peculiar sensation known to us as the perception of a green color. And this is true. The green tree does look green to ninety-six or ninety- eight persons out of every hundred; nay, to even a greater percentage of women. To say what looks green is not green, is a quibble, an attempt to make a new mean- ing to the word. All that we know or can know of the material world through the senses, without reason, is that it produces sensations in us; but that we do know, and know with certainty. So far from the eye not giving a true report in giving color, it gives a report which modern science shows to be richer in content than was formerly dreamed. The chemist thrusts a fragment of an unknown substance into his Bunsen flame, and instantly tells from the play of colors in the blaze the chemical nature of the substance. The green leaf is shown by its greenness to have its particles so arranged as to make light reflected from it vibrate at a certain frequency. All other forms of sense-perception are in like manner truthful. We may carelessly misinterpret the report of sight, and, in Charles Darwin’s expressive phrase, “fill the gaps of knowledge with loose and unfounded speculation.” But, if we attentively, carefully consider what it is that we see, we may be certain that we see something, and some- thing real. And all processes of the intellect are simply THE REALITY OF KNOWLEDGE 35 processes of direct sight, internal or external. Reasoning, as an intellectual process, is the direct perception of the interrelation of truths ; and, as an art, it is the arrange- ment of truths in such a mental order as to make their interrelation visible. He who argues to show the inabil- ity of the human mind to attain or perceive truth is, with gross inconsistency, himself depending upon the veracity of his own internal sight to see the validity of each step of his fallacious argument. But it is said that we can, after all, only see things as they appear to us. Again I enter the demurrer. What of it? Of course, we can see things only as we see them. That is plain enough. And our vision is very limited. That is plain enough. But, as far as we see, we see. Is not that also self-evident? A child sees in a circle not a thousandth part of the wonderful truths which the mathematical genius of ages has evolved out of the simple figures ; but the child certainly sees the circle, the equidistance of its centre from all parts of the boundary, the equal curvature of all parts of the boundary, and the equality of ail its diameters, and this is seeing something real and something valuable. The highest geometer does not see in the circle all its relations. From century to century new truths are evolved from that simplest of curved figures ; but all that the geometer Has seen he has SEEN. How what he has seen appears to the Intellect which sees all things, of course, the geometer cannot know. But of this the geometer is certain: that all human mathematics must be included in the knowledge of an Infinite Intellect. Absolutely perfect knowledge of a circle can never make the equality of its diameters appear a falsehood, or reduce the ratio of its circumference and diameter to any exact numerical equivalent. 36 POSTULATES OF REVELATION So with all other human knowledge in all departments. It is the knowledge of relations; but, when carefully analyzed and corrected, it is a real knowledge of actual relations. It is the knowledge of the relations as they appear to us; but that is a real knowledge as far as it goes. It is knowledge of the relation of the relations to a finite perception. To deny that the human mind can come to any real knowledge of the universe is, then, only to justify Cicero’s remark,—that there is no opinion so absurd that is not held by some philosopher as truth. In this case the absurdity is self-evident ; and yet it has frequently been maintained that we know that we know nothing,— that is, we do not even know that we know nothing, and that we must doubt all things, even doubt whether we doubt all things. To this we are reduced by the doctrine drawn from Kant and Swedenborg,—I think by misinterpretation of their language,— the doctrine that space and time are sim- ply regulative forms of human thought; a doctrine ren- dered popular among English-speaking people by Carlyle’s weird prose poem, “Sartor Resartus’’; a doctrine erring on the side of idealism as greatly as the doctrine of the identification of space with bodily extensiveness on the side of materialism. Space and time, instead of being as Teufelsdréckh puts it, the clothing of the material world, are the limitless atmosphere in which the material world is immersed. The material world exists, so far as we can see, only for the sake of its symbolism. It is a language whereby we can express to each other our thoughts and feelings about space, time, and spirit; and we can thus use it, only because it is a language wherein we are addressed by the THE REALITY OF KNOWLEDGE a7 Infinite Spirit whose thoughts it embodies, whose power and love it manifests, To the reality of these things seen by the inner eye — space, time, motion, force, spirit, or self—and to the reality of our knowledge concerning them, all the experi- ence of life bears an ever-accumulating testimony. Her- bert Spencer resents with indignation the insinuation that he supposed there could be any vice in the constitution of things. Other writers, of even more pronounced mate- rialism, have affirmed that they rest with implicit con- fidence on the everlasting harmony of the movements of nature. We cannot live without that faith: even the earthquake does not destroy the faith of the survivor in the stability of the earth on which they re-erect the fallen city. Peirce analyzed this confidence in the uniformity of nature into a moral confidence in the truthfulness of God. A student asked him one day in my hearing, How do we know that the sun will rise to-morrow? And he instantly replied, Exactly as we know everything else that we do know; on the veracity of God. To sup- pose that the course of nature will be interrupted without a sufficient reason is to suppose the Source of the uni- verse unreasonable and false. To suppose that the faculties of man inevitably and continually deceive him, so that no carefulness of analysis and of scrutiny can ever make him justly certain that he knows anything, is not only, as I have already shown, an intellectual self-contradiction, an inconceivable intellect- ual absurdity, but it is also a denial of our highest moral ideals, a making of ourselves more truthful and noble than the Infinite Source of the universe in which we are but a part. 38 POSTULATES OF REVELATION Oh, never deem This world a dream Of things which are not what they seem; For He who hurled Through space this world, And the starry skies above unfurled, Can never lie, And earth and sky Are what He wrote for the human eye. The fool, indeed, Or child, may read Only the letters with careless heed, And fail to see What mystery Contained in the sacred whole may be; But he whose sight Is open to light Finds the page with heavenly glories bright. Though the clearest ray Of the infinite day, Through this elder Scripture beaming alway, Gives the steadfast hope That there yet shall ope On our stronger vision a wider scope ; — When through Christ’s grace We, face to face, Shall see what passeth all time and space; When the brightest dream Of the present shall seem But darkness beside that immortal beam. Yet bright also Is the present glow Of the glories of heaven that round us flow; And on Nature’s face We still may trace The tokens of Godhead in every place. THE REALITY OF KNOWLEDGE In every line God’s power divine, His love and wisdom, steadily shine. In His hand we lie, And with raptured eye Read His glorious truth on earth and sky. 39 Tie THE INFINITE KNOWABLE. We endeavored in our second lecture to show that the first fundamental faculty of the human being, of the real self within us, is the faculty of sight; that is, of perceiving truth. This faculty corresponds to external vision; it is the internal vision by which external vision is analyzed and understood; it is the internal vision by which we see the entities without us, of space, time, and mechanical force producing motion, and of a fourth some- thing which moves, and gives us thereby our notions of motion, figure, color, hardness, etc. It is the internal vision by which we see also the entities of the microcosm, the powers of intellect and feeling and will, and of an internal fifth something, the self, the ego, the me, the soul, the subject which thus sees what is without and what is within itself. We endeavored further to show that what we thus clearly see is something to be seen. The external world is not a delusion, but a reality: we can know of it only its sensible properties and its time and space relations ; but there is nothing more that we need to know. When I see a piece of red granite, I see only a something that looks red to me; but I see in the peculiar tone and variety of its color that it is a something which is very hard, will stand firm under great pressure, is composed THE INFINITE KNOWABLE 41 of three kinds of crystals, each with such and such sensi- ble properties, that under fire it would behave so and so, that it is capable of a high polish, that it is a portion of the oldest rock on the globe found in substantially similar form in such and such chains of hills, that its crystals on ‘decomposition would yield such and such gases, such and such metals, and so on, and so on. What more do we want? We see something which has such and_ such physical properties; that is, which could, under the right conditions, manifest to us such and such sensible prop- erties. The idealist must grant this, and the materialist has no right to ask the realist to grant more. But the realist has the right to ask the materialist to grant that the other faculties are as trustworthy as those of sense- perception. I see the immaterial entities of space, time, spirit, and force. I see them by the inward sense even more clearly than I can perceive the sensations which reveal the existence of matter. No other man’s blindness can prevent my seeing these immaterial and spiritual entities. The materialist’s denial of the trustworthiness of my sight can no more make it untrustworthy than the color-blind man’s denial of the perception of red could destroy the reality of my vision of those lower rays of the spectrum. The reality of the soul’s power of perceiving, of com- ing into immediate contact with and vision of realities, having been vindicated, the next question is whether it can lay hold of the Infinite, the Absolute, and the Uncon- ditioned. This question is one of those most earnestly debated by metaphysicians. One class have zealously taken the negative, the other the affirmative, in regard | to all three divisions of the question. Our faculties, say \ 42 POSTULATES OF REVELATION one class, are, of course, finite and limited: they cannot possibly lay hold of the infinite, the boundless. Our faculties are tentative; they attain only approximations ; they can never comprehend the absolute, the perfect. Our faculties act only under narrow conditions: they cannot seize upon the unconditioned. Yet the very fact that we can discuss such a question is a fact of sublime significance. A child of less than four years, wholly unaware that I was overhearing her soliloquy, said one morning in a pensive reverie, “‘ How much easier it is to think than it is to do! Now, witha dog it is just the other way.” The human faculties excel those of the brutes most notably in this,— that the brutes so seldom and so feebly manifest any power of transcend- ing, in their imagination, their faculties of action. The saving efficacy of Christian faith lies in its giving us a vivid sense of the presence of an all-loving but a just and holy Father, who can forgive the penitent, but who will inflexibly bring punishment upon those who choose evil. The debate of the highest importance in all ages of human society is, therefore, on the evidences of Chris- tianity, not in the narrow sense in which the phrase is sometimes used, but in the broad sense, including a dis- cussion of those things which Christianity assumes or takes for granted to be true, the more important of which are the being of God, the reality of his moral law, and the existence of a life after death,— an immortal life in which the sanctity of that law shall be more fully avouched. It is by some denied that man has any faculties by which he can attain any knowledge on such questions. — ——— a THE INFINITE KNOWABLE 43 And yet man not only transcends, in his imagination, all his faculties of action and all his imagination of the possibilities of action, but he transcends in his reason all his imagination of the possibilities of imagination. Who can imagine points in space which are neither in, above, nor below the plane of the horizon? Who can imagine epochs in time which neither were before nor will be after the present instant? Yet the mathematician can locate any number of such points, determine any num- ber of such epochs, and by rigid demonstration show the distance of the centre of the earth from each point at each epoch. What his imagination pronounces to be ab- solutely impossible, his reason thus surveys and measures as though really existent. In like manner, in philosophy, the reason asserts with emphasis the existence and properties of that which the imagination is powerless to construct. Yet even reason cannot penetrate into the ultimate re- lationship of space and time to spirit. Our own sense of the ineffable supremacy of the finite spirit over finite time and space disposes us to consider the possibility that the Infinite Spirit, by his omnipresence, constitutes space ; by his eternity, time. But herein we rise as far above the stretch of reason as reason rises above the flight of imagi- nation. And this power of dimly peering into regions transcending the infinite as much as the infinite tran- scends the imaginable, what a sublime power it is! How emphatically it affirms the reality of our apprehension of the infinite, the absolute, and the unconditioned! The men who deny our knowledge of religious verities, in their very denial of the possibility of our laying hold upon these high objects, show that they do lay hold of them. 44 POSTULATES OF REVELATION If they did not, if the incapacity of the human mind was what men of that school of thought declare, they could not argue upon it: they would be forced to content them- selves with a blank denial that they understood anything about the question. Their comprehension of the terms of the question demonstrates that they have an apprehen- sion of the meaning of the terms. There is, then, in the human intellect, finite as it is, a power of seeing that the Infinite at least exists. In the ego, the self-determining subject, lies something akin to the Unconditioned and the Infinite,— something which, in the midst of its conditioned thought, appre- hends the existence and attributes of the unconditioned. We are, however, told by writers of the Hamiltonian school that we can attribute no attributes to the infinite, or to the absolute, or to the unconditioned. The same remark was made by the first great Christian philosopher, Scotus Erigena, in the ninth century. We can affirm nothing of the infinite, says Scotus, because every affirm- ation is of the nature of an equation between the subject and the predicate; and nothing can be set in equation against the infinite. Yet Scotus goes on to predicate excess. An affirmation may be of inequality as well as of equality. God is not great, he says, because he is more than all greatness; nor good, because he is more than all goodness; nor wise, because he is more than all wisdom. In like manner, Herbert Spencer asks whether there may not be a mode of existence transcend- ing consciousness as much as that transcends uncon- sciousness, The word “infinite” is used in three different but cognate significations: first, in the Hamiltonian sense, /~ LL THE INFINITE KNOWABLE 45 the mere etymological sense, as if from a past participle, —not finite, not bounded, indefinitely large; secondly, in a stricter metaphysical sense, not only indefinitely large and unbounded, but, in the direction under con- sideration, incapable of being bounded,— not only infinite, but, to coin a word, infiniendum; thirdly, in its highest sense, the Infinite, that which is incapable of definition or boundary in any direction. To this third meaning of Infinite apply more nearly than to the others the denials of the Agnostic school. But the reason does not clearly demand the existence of an entity having infinitude in every attribute. The reason does not demand therefore the existence of the Infinite as thus described. For aught that reason can see, the infinite spirit, the infinite space, and the infinite time may be heterogeneous co- existences, of which neither has any of the attributes of the other. But with regard to infinite space we can certainly make affirmations. It is in all its parts space; it has every- where its three dimensions; it everywhere offers a fields for coextension. So with infinite time we certainly can make similar affirmations. Let us, however, observe that many modern writers (led partly by the Kantian doctrine of the forms of thought, and partly, perhaps, influenced by a curiously literal translation of a sentence in the Apoc- alypse into our modern tongues) make a distinction be- tween boundless, infinite time and eternity, using the word “eternity” to indicate an independence of time, just as we use the words “ideal” or “imaginary” to indicate independence of both space and time. Let us now observe that, if we take infinity in the sec- ond sense,— that is, real infinity in given directions and 46 POSTULATES OF REVELATION on given attributes,— there is a great practical difference in the ease and certainty with which we may argue. Not to confuse ourselves with logical terms, we may roughly state the difference in this way,—that we can argue to in- finity much more safely and certainly than we can argue from it. This remark holds true in whatever department of thought we may be moving, whether in simple geom- etry or in the highest and most intricate theological prob- lems. Let us take as an example the hyperbolic spiral. A pair of shears stands open, one blade horizontal, the other in a vertical plane above it, making an angle of 64°. Let us suppose the blades of such a length that, if the upper were closed down upon the under one, its point would describe an arc five inches long. Now, suppose that, as this upper blade comes down, both blades lengthen in precise proportion to their approach. That is, when they make an angle of 32°, they are twice as long as at first; when an angle of 16°, they are four times as long; when at 8°, eight times as long; when at 4°, sixteen times as long; when 2°, thirty-two times as long; when at 1°, sixty-four times as long; and so on forever. When at any angle, say 1°, if the increase of length in the blades were to stop, the points would be separated by an arc of one-sixty-fourth the curvature, but of 64 times the radius of the arc at first. It would therefore be an arc of the same length, five inches; and there would be an arc of that length always separating the points of the blades. But, as the angle grew smaller, the arc would erow straighter, and the points of the blades grow farther apart. At the distance of a few hundred feet the distance would be practically five inches, and from that point out through infinite space remain five inches. The end of THE INFINITE KNOWABLE Ay the lower blade would run out on a straight line, the end of the upper blade on a hyperbolic spiral; and it has been easy for you to perceive with certainty that this hyperbolic spiral runs out into a form which, in the infinite distance, becomes a parallel straight line five inches above the first. But, go now in imagination out to an infinite, or even to a moderately great, distance, and see. Here are two parallel straight lines five inches apart: one is really straight, and the other, you are told, is a curve which runs back in this apparently straight form for miles and miles and miles, and then becomes a curve. What of it ? Can you by any imagination, or effort of reasoning, tell what kind of acurve it is? Where is its finite origin? What the law of its formation? Not at all, there is infin- ity in the premises given you; and from infinite premises it is seldom possible to draw finite conclusions. Numerous examples might easily be given illustrating in a similar manner the fact that in the science of analyti- cal geometry, and of the differential and integral calculus as applied to space, it is comparatively easy to pass (by the most rigid and certain deductions) from the relations of finites to the relations of mathematical infinites,— not simply of mathematical indefinitely large quantities, but mathematical infinites of an infinite order,—but very much more difficult to pass from the relation of infinites to that of finites. I have elsewhere shown that the same thing holds in theology, and that a majority of the theo- logical errors and fantasies of outgrown sects in Christen- dom have actually grown from or been supported by arguments drawn from the infinity of God.* And, even at the present hour, the most fascinating of modern specula- * The Natural Sources of Theology, page 13. 48 POSTULATES OF REVELATION tions in science, philosophy, and religion, are insecurely built upon deductions from premises involving infinity. The sciences of space and time —that is, mathematical cal- culus — show and illustrate the fact that, in order to argue from premises involving infinity, very peculiar precautions against error are necessary. With these precautions, we may perhaps argue safely, and come to indisputable con- clusions; but without them the liability to error is a thousand-fold greater when arguing from infinity than when arguing to it. The philosophers who most earnestly deny the reality of our knowledge of the Infinite, and forbid us to make any affirmations concerning it, are continually making affirmations themselves and arguing from them. I have mentioned Scotus Erigena’s saying,—that the Deity can be called neither wise nor good, because he is more than wisdom and more than goodness. In this earnest denial of the possibility of making an affirmation Scotus was affirming more than all affirmations. The modern thinker, opposing theology in his earnest advocacy of his doctrine of the unknowable, simply repro- duces the doctrine of Augustine, of Erigena, and other Christian philosophers concerning the inscrutability of God. Indeed, in the Pentateuch, a writing of antiquity, but certainly of earnest theism, the same doctrine is sub- limely stated. Thou canst see my presence, the Lord is represented as saying: no manner of similitude is shown thee; but thou recognizest my presence by the operations and results of my word. Herbert Spencer is indignant at theologians who attrib- ute consciousness to God. May there not be a mode of being, he cries, as much transcending consciousness THE INFINITE KNOWABLE 49 as consciousness transcends unconsciousness? Of course there may ; and, if Mr. Spencer had known anything of the Christian theology which he speaks of so contemptuously, he would have known that all Christian theologians of any elevation of thought have acknowledged it. It is the con- stantly reiterated statement of the Hebrew Scripture that God’s thoughts are not as our thoughts, that his ways are as much higher than ours as the heavens are higher than the earth. In Agassiz’s contemplations of God in the cosmos, that great naturalist, whose childlike relig- ious trust in the paternal character of God made him undervalued by modern thinkers tinctured with material- istic and atheistic philosophy, declares emphatically that we can form no image or picture to ourselves of the divine consciousness, because the intellection of God is not conditioned in time or space. Agassiz drew by in- duction from the cosmos what philosophy draws from the microcosm; and the prophets declare by inspiration that in the divine mind. there is no tentative, progressive ad- vance of knowledge, but that in that intellect the end is known from the beginning, and every detail is simulta- neously conceived. This mode of being, of course, is as much above our human consciousness, or any picture of consciousness which human imagination can draw, as con- sciousness is above unconsciousness. Nevertheless, this mode of the Divine Being includes rather than excludes consciousness. Conscious spirit, possessing knowledge, wisdom, power, and love, is the highest thing that we can imagine. It thus becomes, as Aristotle has shown, our fittest expression and symbol of the highest being which reason can apprehend. Of course, we are not to attribute to the Infinite Being 50 POSTULATES OF REVELATION the limitations of our personality. We are not to suppose his thoughts are, like ours, necessarily consecutive ; nor his love, like ours, necessarily partial. But, in imitation of the processes of reasoning in lower things, we may take the attributes of personality, and imagine them indefinitely extended, and judge from their behavior under this indef- inite extension whether they can bear extension to infin- ity. If not, they are not attributes of the Infinite. But, if yes, then they are attributes of the Infinite and Absolute. The indefinite expansion of the field of intellectual con- sciousness may be conceived without necessitating the slightest breach of the laws of intellectual perception. And, when the expansion is infinite, we arrive without any violence to reason or imagination at a point above im- agination, but real to reason, —the existence of an Infi- nite Being to whom is known all that may be known, all that is and all that is not, all that is possible and all that is impossible, to whom the knowable and the unknowable are alike lost in the known. . But the greatest difficulty is usually felt in reconciling the conception of love with the existence of the Infinite, That God is wisdom seems to many persons easier to be- lieve than that God is love. Yet, when we consider the matter fully, there is no real wisdom without love, the de- sire to confer happiness on sentient beings. Imagine this growing and increasing in the mind and heart of one who is growing in wisdom and power. With the increase of wisdom, such a mind would see a gradation in kinds of happiness ; and the desire would constantly be for giving purer kinds of happiness. It is easy to see that this increasing beneficence, accompanying increasing wisdom and increasing power, involves no self-destructive or self- THE INFINITE KNOWABLE Si contradictory elements as it passes on to indefinite expan- sion, It may therefore be reasonably predicated of the Infinite. We have, therefore, no philosophical hindrances, but, on the contrary, strong philosophical helps on the path to accepting the teachings of the Jewish and the Chris- tian Scriptures concerning God. Neither the finiteness of man nor the infinity of God presents any real difficulty to the partial knowledge of God by man. On the other hand, we have, before entering on any detailed examina- tion either of the world without or of the world within, the strongest presumption from this preliminary survey of the general field that the theism of the Hebrews is philosophically true. The very nature of the soul is to see, to feel, to will. Among the truths which it sees is the truth of its own superiority to the external world, and its own inferiority to the great First Cause of the universe. It sees that the Cause of the universe is infinite, and can- not be comprehended in any finite mind; but in the very act of seeing this it sees the existence and the infinitude of this cause. It sees that infinite as the Supreme Cause is, that cause is perfect, absolute, self-existent, self-determined, existing in a mode unconditioned and uncontrolled,—a mode in- conceivable to our imagination, but seen by our reason to be the mode in which God exists. The mind cannot see that it is limited except by tran- scending its limits. Absolutely unthinkable is void, is ab- solutely dark: we cannot peer into it, we cannot know it or talk about it, except as we may of yellow sounds. The absolutely unimaginable may be brought under the do- main of reason, but the absolutely unthinkable can be 52 POSTULATES OF REVELATION brought under no faculty of the mind. The First Cause is not absolutely unthinkable. On the contrary, it is thrust upon our attention at every moment of our higher life. No man can speculate at all without running back in his speculation to the First Cause, absolutely unimaginable, . but always an object of thought, thinkable, and by that thought separated from the conditioned and exalted to the unconditioned. We think him to be, although we cannot think what or how he is, except that he is infinite in the attributes of real being, absolute in all perfections, and un- conditioned in his existence and action. IV. EEN ALG Ge aUisy ha: THE strict force of our argument in the preceding lect- ure was to show that we could by reasoning, if carefully conducted, arrive at sound conclusions concerning the In- finite, the Absolute, and Unconditioned, and that there was no objection arising from the infinity of God or the rela- tivity of human knowledge insuperably in the way of our ascribing to him the spiritual faculties of wisdom, love, and will. But we also showed that it is logically safer to argue from the finite to the infinite than from the infinite to the finite. By what induction, therefore, from the finite shall we show the infinite wisdom of the Deity? Is there any induction that is valid? Two lines of induction have been followed by theologians in all ages. Socrates, in the Memorabilia of Xenophon, gives us admirable examples of the first. He shows that the human frame, and par- ticularly the human eye, is built with such an admirable adaptation to its purposes as to indicate a wise Creator. This is known as the teleological argument. It was pecul- larly suited to the Greek mind: their very language indicated in the recognized meanings of the word Zéos, that they identified cause and effect in the adaptation of a means to an end. If we attempt to formulate this argument from design into a canon of induction, it might 54 POSTULATES OF REVELATION run something like this: When an organ is found ef- fecting a result, the presumption is that it was created to effect that result; and the presumption is strengthened in the compound ratio of the complication of the organ, the efficacy of its action, the value of the result, and our inability to see other uses for the organ or better means of effecting the result, the presumption thus being readily raised to moral certainty. The other line is the morphological. It was not fully developed by early writers, although finely stated by Cicero as a Stoic argument, but has been made of more importance by men of our own day. A magnificent ex- ample of it is found in the Introduction to Agassiz’s “Essay on Classification,” prefixed to his “ Contributions to the Natural History of the United States”’; also in the lectures of Professor Benjamin Peirce. It is a stronger line of induction than the teleological, but not so readily apprehended by uncultivated minds. The peculiar argu- ment is that, when a material body conforms in its time or space relations to a thought, to a mental law, so that, for example, a proposition concerning one point of its surface or one instant of its duration shall be true for all the points, and for every instant, the presumption is that it was created in obedience to that law; and this pre- sumption increases with the simplicity and beauty of the law, and the complication of the details coming under it. So that the presumption rapidly strengthens into moral certainty. But, in order to feel its full force, we must revert for a moment to the nature of time, space, and force. By force, I mean the activity of that power which imparts or resists motion. It lies dormant in certain points of space which EL ee a re FINAL CAUSES 55 we call the centres of atoms. What the atoms are we cannot tell, otherwise than that they are points in space from which, locally, the manifestations of force proceed, as I have once before said. The idealist must admit so much as this, and the materialist cannot justly claim to know more. But we see by the inward eye space so clearly, so per- fectly, and, as it were, on every side, that we know the power which is manifested in force does not inhere in or flow from the point as its efficient cause. The cause may be in the place, but the place is not the cause. In like manner we see time so clearly and distinctly that we know that the instant of time is not itself the efficient cause of the force revealed at its arrival. The force in an atom—that is, in a centre of action—re- veals itself in the phenomena of motion and of the resist- ance to motion. These phenomena arrange themselves readily under two groups. The one group betrays polar- ity of a more or less pronounced and of a more or less complicated character. That is to say, it shows that the forces in the atomic centre act with varying strength in various directions, making fixed angles with each other. Such are the phenomena of chemical quantivalence and of electric and magnetic disturbance, and the phenomena of crystallization. To this group also we may annex those properties of matter which show a constancy and individ- uality in the strength of the forces in a given atom; for example, the laws of definite proportions, in all the various forms in which such laws pervade chemistry. The other group consists of those manifestations of force which seem to act equally in all directions from the centre, like the forces of electrical repulsion and attrac- 56 POSTULATES OF REVELATION tion, or like the force of gravity. Whatever is purely physical and reducible to the effects of mechanical force can be explained by referring it to one or both of these modes of the manifestation of force. The first law of motion as determined by physical ex- periment is that a body in motion continues in motion with uniform velocity in a straight line forever, unless subjected to accelerating forces. These accelerating forces act, as we have just shown, in one of two modes, either by polarity on definitely arranged axes or in de- flection around a centre. By the latter mode we obtain the revolution and rotation of planets, the oscillations of the pendulum, and similar phenomena; while by the first mode we obtain chemical changes, the aggregation of crystals, and so on. By either mode the result tends either toward a dynamic equilibrium, as in the planetary motion, or a statical equilibrium, as in crystals. In the passage toward a form of permanent equilibrium, atoms and masses are frequently passing into positions of unstable equilibrium, where, like the ass between two bundles of hay, they are equally drawn in various direc- tions. For example, take a body of simple linear polarity, like a dipping needle, and place it with its poles exactly reversed. It has, so to speak, the choice of innumerable directions in which it can turn to reverse its poles again to their normal position ; and, without figurative language, if the poles are exactly reversed, it requires only an infin- itesimal force to decide the path in which it shall rotate back to its right direction. But what decides the direc- tion of this infinitesimal impulse, which sets in motion what may prove to be a chain of interlinked reactions of great magnitude? If we say that sometimes one thing, FINAL CAUSES 57 sometimes another, produces the initial impulses, then we obtain results as disconnected as the causes of the infin- itesimal movements. But, if we admit that the causes of the beginnings of the motion are interconnected, then the results will be interconnected ; and the nature of the con- nection of the effects will show the nature of the inter- connection of the causes. When the effect is manifested in a resultant material form or in a resultant measurable motion, the crystalline or the amorphous form, or the rhythmic movement, may show that the guidance was simply the atomic forces themselves in their combined action. When a force is manifested in motion or in pressure, the direction of the motion can be guided only by force. But, when the atom is passing through a posi- tion of unstable equilibrium, it can be guided, as I have just shown, by an infinitesimal force; and, if the position is absolutely unstable, the guiding force may be absolutely infinitesimal,—that is, may be zero. There is, then, in the very constitution of an atom-built world, an opportunity for the exercise of a spiritual guidance of force. This spiritual guidance is of various kinds; but, if we keep ourselves near the philosophical foundation of con- sciousness as possible, we shall look first at voluntary motion. To return to one of the illustrations, I deter- mine to write the word “will.’ Immediately upon my vo- lition the point of my pen traces the word “will” upon the paper. Here is a voluntary guidance of my fingers and of the pen held in them, to the effecting of this result by mechanical motion. My will has certainly no finite or appreciable physical force in itself. Its action upon my fingers and the pen is wholly inexplicable by either spirit- ual or materialistic philosopher. It is, as I have already 58 POSTULATES OF REVELATION shown in the second lecture, magic. No explanation of it can be given. The physiologist shows us the nerves re- porting the sensation from the fingers’ ends to the brain, and the nerves carrying the command back from the brain to the muscles, in obedience to which they alter- nately contract and relax in such a manner as to make the pencil write “will.” But the physiologist can show no connection between the cells of nervous matter in the brain and the form of the sensation reported or the form of the command given. All that we know is that the nervous matter, the muscular tissue, and the blood glob- ules are bodies in a state of unstable chemical equilib- rium, so that they tumble down at an infinitesimal touch into the lower forms of urea, carbonic dioxide, etc., and that the conscious will directs, by magic, the paths in which they turn in their fall, and thus determines the re- sultant motion of the pen. I say by magic, for the con- scious self is not conscious or cognizant of any of these intermediate steps and agencies which he between its vo- lition and the final result. Here, then, is a vera causa, not in the physical nexus; for there there is no cause needed, the absolutely infini- tesimal being zero, and it only requiring an absolutely infi- nitesimal force to direct the stream at its beginning. But here is a vera causa as a logical cause for the guidance of forces. And it is the only vera causa known to us which does guide and direct the action of forces. The forces of nature are thus partially under our control. The ego, being absolutely dissevered by the widest conceivable or rather inconceivable gulf from matter, from the force which produces motion, is enabled, by this magic of con- trol over the unstable equilibriums in the body, to guide ee ———— FINAL CAUSES 59 not only the forces of cerebral and nervous and muscular contraction in our own body, but thus the external terres- trial forces of sun and wind and wave and electric current and chemical reaction to our own purposes. But there is also guidance where we are not conscious of guiding, Take this very instance of simple muscular movement. The child wills to grasp his rattle and shake it, and very soon learns to do what he desires. His will guides his muscular force to the seizing and shaking of the toy. But the will and the final result is all that enter his conscious thought. His will is the real cause which determines the result of shaking the rattle. But where lies the cause of the guidance of the intermediate series of relaxations and contractions? This was not guided consciously by his will. I guide by my volition the movement of my finger ends by which I write the word, but I do not guide by con- scious volition the nervous and muscular movements of the arm. Iam not even conscious of their existence. Yet there was guidance there, otherwise the arm would have moved aimlessly as an infant’s. And that guidance was put ultimately under control of my conscious volition, else the words written would not be what I desired. The only vera causa known to us in the guidance of the force is, as I have just shown, a conscious will, a guiding intel- lect. Surely, the law of parsimony would lead me to attribute the whole guidance to intellect, and thus regard my body as a machine made with wonderful skill and put under my partial control. : When we step back of the conscious will, we observe that the will is prompted by desire and guided by reason. In other words, we are reasonable beings, not acting capriciously and without motive. There is a basis in 60 POSTULATES OF REVELATION our own nature for the division of the inductive argu- ment for the wisdom of God into the teleological and the morphological lines. In Paley’s well-known treatise, and in the major part of the eighth Bridgewater treatise the arguments are from the apparent design of fitting a means to an end or making a tool for a purpose. Thus Socrates argues that the protection of the eye from sweat by the brow and from dust by the lid, and the perfect adaptation of the position of the eye in the head, and its internal organization to the purpose of seeing, proves that it was made skilfully as an instrument for sight. It is the modern fashion to despise this argument, and there were in the days of Socrates those who despised it. One popular writer of our day calls it the carpenter theory of creation, and another speaks of it as a miserable watch- tick business. It is by others supposed that the doctrine of evolution would, if established, thoroughly dispose of it. All these objections and criticisms are founded upon a misconception of the real nature of the argument. When Goethe asks contemptuously, — “Was war’ ein Gott, der nur von aussen stiesse, Im Kreis das All am Finger laufen liesse!”’ he is building a man of straw to fight with. No Chris- tian theist supposes God to be outside his world, man- ipulating it from without. No Christian philosopher ever supposed that God “manufactured ” the world, or “ built” it, or “made” it, or “shaped” it in any such exterior sense. The theology of both the Jewish and Christian theologians has always been consonant with that of Saint Paul, who says of the Divine Being that zz Him FINAL CAUSES 61 we live and move and have our being, and who quotes with approval from Cleanthes and Aratus the words, Tod yap kal yévos éopev, “ For we also are his offspring.” In other words, Christian theology, and Jewish also, have been as pantheistic as reverent reason and devout common sense would permit them to be; and those who ridicule the argument from design on the ground that it makes the Deity a carpenter, a manufacturer standing outside his work, either fail utterly to apprehend the argument or else they carry their pantheism beyond the limits of reverent reason and devout common sense. The objection drawn from the doctrine of evolution is equally futile. Organic development is simply a mode of carrying out a plan: it does not alter the nature of the plan. If it were possible to prove (what I deem the extravagantly improbable, if not impossible, theory) that the human eye was gradually developed by a process occupying a million ages, from the diffused sensitiveness to light found in the zodphytes, it would not affect the strength of Socrates’s argument from the eye, unless you could also prove that this gradual development was a necessary result of mechanical force acting upon for- tuitously scattered atoms of matter. The organic growth of the eye in the individual from the embryonic cell to a perfect manhood is just. as inconsistent, and just as consistent, with the argument for design from the struct- ure of the eye as would be an organic growth from spe- cies to species in an ascending series through the eons. We may therefore dismiss the question of the evolution theory from the consideration of the arguments. And I think we may also dismiss the objection impled in the contemptuous epithets of watch-tick and carpenter theory. 62 POSTULATES OF REVELATION The argument from design does not imply a God who stands outside the world. What it does imply is that the Divine Agency is not an unconscious necessity, aris- ing from mechanical force operating within the Divine Being to bring out the forms of the universe without His knowledge or approval; but it is the action of in- finite power, under the guidance of unerring wisdom, freely doing what is best because it is best. The canon of induction from teleological considerations simply declares that the eye is effective as an organ of vision; that the complication of parts of the organization conducing to this is very great; that the value of the result is im- measurable ; that we see no other use for the organ than vision, and that we can imagine no improvement or better means of effecting the result; and that, therefore, the presumption that the eye was made for seeing amounts to a moral certainty. There is no presumption here, and no implication, that the eye was made in any other mode than by organic growth. The evolutionist has no more reason to apply the contemptuous epithet, “carpenter theory” than one not believing in evolution would have for retorting, “Topsy theory.” But there are other and equally strong arguments by which to show the presence of thought in the guidance of force. As the human will acts not only in devising means to ends, but also freely uses material forms as symbols or as expressions of its own state of thought and feeling, it learns to see in the forms of the exterior world a symbolic meaning or a direct expression. A work of art is not a means to an end, but it is the expression of a thought or a feeling. Thought may be expressed in material forms without symbolism, and without any other feeling than (ee — ee a =—~*ou FINAL CAUSES 63 the desire to express the thought. Thus the diagrams of the geometer are the direct expression of his mathemat- ical ideas, in which he may take no other interest than an intellectual interest in their truth. The designs of orna- mental architecture, on the other hand, express not only the thought of the architect, but his taste, which is a slight degree of artistic feeling. Very little more can be said of the simplest forms of sculpture and of drawing. But, when we pass to the higher forms of either of these arts, or add coloring from the painter’s pencil, we have the expression of feeling, or sentiment, predominating over the expression of thought. The universe is far more than a mere series of adapta- tions‘of means to ends, unless we exalt the word “ends” to include the expression of thought and feeling. The universe is a work of art. It is a combination of philo- sophical ideas expressed in their clearest forms; it is the manifestation of an all-embracing divine love; it is a poem, the utterance of all truth and beauty and goodness. And those who object that this language, like the teleological, makes the creation something outside of and separate from the Creator, put into it a meaning which is not necessarily there, and which is certainly not intended by those who use these figures. When I see a geometrical diagram upon a blackboard, I know that the particles of the crayon and the surface of the board have had no power to guide the movement of the crayon to the formation of the figure. I know also that the figure does not exactly and rigorously fulfil geo- metrical law. The chalk line has an appreciable width. It is not a mathematical line without breadth. And the centre of this chalk line does not rigorously fulfil the con- 64 POSTULATES OF REVELATION ditions of any geometrical locus. Nevertheless, the ap- proximate fulfilment of those conditions by the white mark upon the board gives me an absolute certainty — that is, if the figure be moderately complicated —that the geometrical conditions were known, explicitly or implic- itly, to the mind which directed the drawing of the dia- gram. This conclusion would not be affected by any speculations or any discoveries concerning the actual mode in which the diagram was drawn. A circle may be drawn in a great variety of ways, each based upon a dif- ferent mode of looking at its geometrical nature. The mechanical draughtsman may draw it with a pair of com- passes, basing his method upon the intellectual concep- tion of the equality of the radii. A blacksmith makes it by passing his tire between three rollers, basing his ac- tion upon the intellectual perception of the uniformity of its curvature. The artist drawing with free hand may not distinctly have either of these ideas in his mind; but his feeling of the perfect symmetry of the figure bases itself upon some sort of intellectual conception. In whatever manner, therefore, a diagram be drawn, let us say of the hyperbola and its asymptotes, we find in it invincible proof of the presence of an intellect guiding in some manner, through a longer or shorter series of instrumen- talities, the movements of the crayon. Now there is no valid reason why the same induction should not be made from the forms of nature. The whole creation is a wonderful collection of geometrical diagrams, from which the geometer and the physicist have de- veloped all the mathematical sciences. The thoughts of Newton’s “Principia” and Laplace’s “ Mécanique Cé- leste,” and Peirce’s ‘Analytical Mechanics,” and Hamil- FINAL CAUSES 65 ton’s “‘ Quaternions,” were all suggested by the forms of nature in which the elements of them were found em- bodied. In this assertion it is of course not intended to say that the creative Mind takes the same view of space and time relations as is taken by the mathematician, nor that the Infinite Spirit which created the universe is obliged to go through the same processes of induction and deduction by which we arrive at an idea and at its mode of expression. To charge Christian theism with imposing such limita- tions upon the divine thought is to attribute to it a con- fusion which is not in it, but in the mind of its critic. What the Christian theist does say is that the atoms of matter are in millions of examples so arranged as to ex- press with the closest degree of approximation our own a priort conceptions of space and time. In numerous in- stances the forms of nature have suggested to the mathe- matician laws of space and of time, extending far beyond the examples which suggested them. A development of these laws by a@ priovt reasoning, entirely independent of the generalizations of experience, has led to the predic- tion and the discovery of new phenomena in nature; and these predictions have been, sometimes after the lapse of centuries, fulfilled by observation, as in the familiar instance of the ellipse, studied by geometers as an a priorz form four centuries before Christ, and never discovered as actually occurring in nature until the sixteenth century after Christ. Another striking instance is less familiar. Division in extreme and mean ratio was invented asa purely a priori process in the third century before Christ, and was not known to play any part in the economy of the external universe until 1849, the middle of the nine- 66 POSTULATES OF REVELATION teenth century of our era. These are pure examples of the morphological argument. An idea is attained by a process of internal vision, and examination of the process suggested always by the hints given first by the external world, but the idea not involved explicitly, or even im- plicitly,in the hints. An idea is thus attained which may be thus justly called a przorz, since it is not taken from external observation; and the forms of the outward world have not suggested it, but only suggested the path by which we attain the spiritual intellectual idea. This idea is developed frequently with great fulness and minuteness of detail, and is a commonplace possession of all cultivated minds for years and even for ages before it is discovered that the idea is nevertheless embodied perfectly in external nature. I say perfectly, but of course this is hyperboli- cal language. It is not possible apparently for material objects, whether natural or fashioned by human art, to conform perfectly to a geometrical or algebraical ideal. Even our methods of measurement detect variations from perfect geometric figures and from perfect alge- braical rhythm; and our methods of measurement fall far short of being able to detect infinitesimal error or to es- tablish perfection. But, in judging of that which is made by human art, we arrive at absolute certainty concerning the idea of the artist or artisan without requiring more than a rude approximation to a fulfilment of the ideal. Why, then, should we not have the same certainty in re- gard to the works of nature, in regard to the diagrams of creation? It is not necessary to suppose —and I think no intelligent theist supposes — that the conception of an ellipse, or that the conception of extreme and mean ratio, or that any one of the innumerable mathematical concep- FINAL CAUSES 67 tions of which the world offers us natural illustrations, lies in the divine mind in the form in which it lies in the human mind. We do not pretend to pattern God’s thoughts; but we do affirm that the simplest explanation of the presence in all parts of nature of these expres- sive and approximately exact illustrations of our human thought is to say that the origin of the universe is in a Universal Reason, an Intelligence whose thoughts compre- hend and include all our thoughts. Ii the heavens declare, as Comte says, the glory of Hipparchus and Kepler and Newton and Laplace, then a fortiort they declare, as the Hebrew Psalmist has said, the glory of God. If Hipparchus and his noble successors win immortal honors by deciphering and unveiling the hidden laws of planetary motion, what adoring wonder is due to the Intelligence and Power which guides the planets on their courses! If Maraldi and McLaurin made them- selves a name by showing that the bee’s cell is built on the highest mathematical laws, is there no honor to be as- cribed to the Creator and Inspirer of the bee? Agassiz, and Cuvier, and Linné deserve the high honor they have received for unfolding partially the plan of the organic kingdoms; and is there no profound wisdom and skill in the formation of those kingdoms upon such a plan? The sculptor tells in marble a thrilling tale which stirs the heart ; but the highest praise of his work is that it is true to nature. Is not nature’s work as expressive as sculptor’s, and the Creator of the human frame the highest sculptor ? Was there no meaning, Emerson asks, in the live repose of the valley behind the mill, and which Homer or Shak- spere could not re-form for me in words? The painter re- forms that meaning in a landscape, and expresses his own 68 POSTULATES OF REVELATION feeling thereby. The meaning is a breathing of peace from the beautiful repose: it is a benediction, it is an out- flow of divine love. The musical composer lifts us up or casts us down. He expresses every emotion of the heart, and carries us by the contagion of sympathy into the region of his own feel- ing. What higher evidence of genius and of spiritual power can be given than by a composer, for example, like Bach, the Shakspere of musicians, who chases away care, and fills the heart with quiet cheerfulness by a merry gavotte or jig; casts it down with sorrow, and wrings it with remorse, by a portrayal of the sufferings in Geth- semane; and again rouses you to heroic endeavor and religious enthusiasm bya grand toccata summoning the hosts of the Church militant to the last grand battle of Armageddon ! But what could Bach do for us, were not the human ear built in wonderful accord with the tones of nature, and trained from infancy to recognize the expressiveness of natural sounds, the mother’s lullaby, or words of endear- ment and words of reproof, the laughter and the sobbing of playmates, the song of birds, and the cries of animals in distress, the wailing of the winds, and the bass of the awful thunder ? The moment that the unprejudiced mind recognizes in the forms of outward nature the evidences of intellect, it rushes not unreasonably, but by sure and safe roads, to the conclusion that the Intellect which framed the universe is unerring in wisdom, and that its wisdom is prompted to action by inexhaustible goodness. Of course, this language is inadequate ; for all finite sym- bols must be inadequate to set forth infinite realities. FINAL CAUSES 69 The Infinite Intellect does not, like the finite, require time for inter-election, but separates truth from falsehood, good from evil, by an eternal action of which we can form no image. Nevertheless, it thus separates, inter-elects, knows. The Infinite Being is not prompted to action by impulses, as we are: there is no pro-motion, or pushing him forward. Nevertheless, his acts are all reasonable in the highest moral and religious as well as intellectual sense. They are consonant, in the largest view of human nature and human destiny, with our highest conceptions of holiness and love. They can be criticised by John Stuart Mill, or by others, only on the previous assumption that the highest truths of consciousness are falsehood, and that man is like the beasts that perish, his highest end being the happiness of this earthly life. The rapid induction by which the unprejudiced mind arrives at the being of one God, infinite in all his perfec- tions, is not illusory ; and we are endeavoring in this course of lectures to illustrate and vindicate some of the postu- lates on which that induction proceeds. The induction is so strong and drawn from such numerous sources that it would be impossible in so brief a course to examine all its parts in detail. V. THE UNIVERSE A WORK OF ART. We have spoken, in a previous lecture, of the two dis- tinct lines into which the argument from design may be divided. The teleological takes instances in which a means is adapted to an end, and argues that the end was the object for which the means was created. This argu- ment has been reproached with making the Creator stand outside the universe, to plan, deliberate, and contrive how to evade or surmount difficulties. But this is a complete misunderstanding: there is nothing in the argument in- consistent with the view that he saw from eternity the whole plan and development of the universe, down to its minutest details. The morphological argument, on the other hand, takes forms or rhythms in the external world, which do not appear to be acting as means to an end, but which conform to laws of thought. In these cases the position of innumerable points, at innumerable instants, can all be expressed by one proposition, declaring the position of one point at one instant. Inasmuch as space and time are impotent, utterly destitute of power or force ; inasmuch as conscious will is the only thing actually known to us as guiding force through positions of un- stable equilibrium,—it is reasonable to infer that this arrangement of points into symmetrical form or rhythmi- cal movement is the work of a guiding intellect. THE UNIVERSE A WORK OF ART 71 The objection that this would make the thoughts of the Infinite Being like our thoughts is not sound. We do not find that different artists have the same ideas of the same form, and it is readily shown that the conception of an indefinitely increasing knowledge does not imply that the lower amount of knowledge is false. The dullest school-boy, in his perception of the human eure hasea correct conception of it, so far as it goes. He expresses the idea of a human body as unmistakably by stiff chalk lines as Raphael by his marvellous multitude and va- riety of living, graceful attitudes. Raphael’s facility shows that his conception of the living body was incom- parably more complete and accurate than the school- boy’s; but his conception, nevertheless, includes the school-boy’s notion of a head, a trunk, and four limbs. Even infinite knowledge of geometrical form would not render false our human knowledge, but would include it. As the school-boy’s rude sketch indicates that in his mind there is some faint likeness to that of Raphael, so our human conceptions of geometrical law, being found expressed in nature, indicate that in our finite minds lies some faint likeness to the Eternal Mind. Of course, we must concede that this likeness does not extend to the method of embodying the conception; nor does any intel- ligent theist suppose that it does. Let us now take a rapid glance at the immensity of the field which is covered by these two branches of inductive proof. Every one is aware how much additional strength is given to an inductive conclusion by a multiplication of instances from which it is drawn, and how much greater the additional strength given by the consilience of differ- ent lines of induction toward one conclusion, An induc- 72 POSTULATES OF REVELATION tion is thus frequently made just as practically certain as a deduction, or even as an intuition. For example, the existence of fellow-men, similar in their principal physical and psychical endowments to ourselves, is only an induc- tion; yet it is a conclusion of which every sane mind is absolutely certain,—as certain as it can be of its own existence. Herbert Spencer says that there is the same certainty of the existence of an ultimate cause of the uni- verse. The existence of such a cause is, he tells us, forced upon our attention and upon our belief by every experience in every day’s life. It is this consilience of innumerable lines of induction which leads us to leap to certainty. We may go further. Spencer used to stop short with the existence of such a cause; he declared it to be absolutely unknown and unknowable; he forbade us to make any affirmation concerning it or to ascribe any attribute to it. But he could justify himself in issuing this prohibition only by a fallacious argument from the infinite nature of the ultimate source of all things. Argu- ments from the infinite are almost always fallacious. Every cause may be known from its effects. The uni- verse is intelligible, fulfilling plans of the highest wisdom and highest beneficence: its courses fight against the wrong-doer and for the upright; and the Cause of the universe is thus avouched to us as possessing the high- est knowledge, wisdom, goodness, holiness. To these conclusions the inductions, also, from every hour's expe- rience conspire in leading; and this consilience gives to these conclusions a certainty as great as that which we have of the existence of our fellow-men. The mode in which the results of induction become THE UNIVERSE A WORK OF ART 73 certainty may be illustrated by the doctrine of mathemati- cal probability. Let us suppose that one of a pair of dice has been carefully measured and found to be a perfect cube; that it is then thrown repeatedly upon a table, and a record kept of the sides which come up. Let us further Suppose that the ace constantly appears at every fourth or fifth throw instead of at every sixth. At first, we may Suppose that this was an accidental variation; but, if it continue constantly to appear too frequently, we shall begin to suspect that the opposite side of the die is the heavier. Let us now suppose that an examination shows that opposite side to be discolored. From this, we should not directly infer that that opposite side is the heavier, although we might infer that it was of a different specific gravity. Let us now try a third line, by throwing the die repeatedly into water. If now the ace comes up every third or fourth throw, it will be scarcely possible for us to resist the conclusion that the side of the six pips is too heavy. Yet, strictly speaking, all the evidence has been only an evidence of probability. The chance that the ace turns up at any throw is one in six, and the chance that it turns up one-sixth of the time becomes greater and greater as the number of throws is increased. Yet in order to have it certain, even with a perfect die, that the ace shall appear one-sixth of the time, we must have an infinite number of throws. A divergence from this sufficiently great would, however, very soon give moral certainty, even if not confirmed by the discoloration on the opposite side, and by throwing the die into the denser medium of water, thus allowing more time for the heavy side to act. Since the tendency toward a greater ratio than one-sixth does not show a change in any one direction, as the num- 74 POSTULATES OF REVELATION ber of throws is indefinitely increased, we infer that the ratio would remain more than one-sixth, even were the throws multiplied to infinity. We are, therefore, justly certain that there is some one cause, constantly acting, to bring up the ace. When two arguments from induction conspire to give probability to one conclusion, that probability increases at least as fast as the product of the separate probabilities. We say, at least as fast, because, while the doctrine of chances gives it that ratio, the moral probability of the conclusion is usually increased by vague and undefined presumptions, not to be measured numerically, and yet to be allowed their just influence in a moral judgment, pre- cisely as the discoloration of the die has justly an influence in the argument, although that influence is incapable of any exact numerical measurement. These presumptions may, in some cases, amount to a great deal, leading the mind irresistibly to exalt the probability to certainty ; while, in other cases, they may amount to very little. But it is always in the power of a sufficient number of in- ductions to make the mind rush to the conclusion that the number might be indefinitely increased, and thus give cer- tainty to the probability. This is the manner in which the laws of physics have been established ; and the con- sent and consilience of induction is the foundation rock upon which the magnificent temple of modern science stands. There is not a single one of her laws, unless we except some elementary laws of mechanics, which rests upon any other basis than inductions of probability. Yet there are numerous laws of physics of which we are just as certain as we are of the simplest axioms of geometry. In arriving at the laws of natural science, the students THE UNIVERSE A WORK OF ART 75 have always been accustomed to leap fearlessly from the indefinitely great to the infinite. Those who oppose the conclusions of theism concede that the great majority of intelligent men agree with Soc- rates and with the Stoics, in seeing the marks of intelli- gence and wisdom legibly inscribed upon the creation. They admit that every form of Atheism, Agnosticism, and Pantheism, whether materialistic or spiritual, has to contend against what the great mass of men consider their common sense. The common sense of mankind asks with Napoleon, ‘Who made these things?” Nor is the common sense of mankind satisfied with the answer,— that they were not made at all, but grew. That reply, whether from the ancient philosophy or from the new, appears to common sense to be a mere quibble upon the word ‘‘made,” as though the word ‘‘make” implied the mode of making. No such quibble can blot out of sight the evident fact that the parts of the universe are exquisitely adapted to each other, in innumerable rela- tions of means to ends, precisely as if by infinite wisdom. It cannot hide the evident fact that the whole universe moves by law, precisely as if in the fulfilment of a Divine ideal. It cannot satisfy the longings of the heart for an infinite love whereon to rest. Nor can it still the voice of conscience; reproving our sins, and giving us dread intimations of the universality of the moral law and of its eternal sanctions. Theism is the natural conclusion, not only of the intellect of man, but of his heart also. Au- guste Comte, the great founder of the school of Positive Philosophy, gives us a singular testimony to this fact in that broad generalization with which he opens his pon- derous “Cours de Philosophie Positif.” He says that the 76 POSTULATES OF REVELATION human race and the individual man always pass, first of all, through a theological stage, in which we attribute the existence and order of the world to a Divine creation. A true, unprejudiced, reasonable examination of this first conclusion of the human mind upon beholding the regularity, intelligibility, and beauty of external nature, will confirm and strengthen it: it will not, as Comte im- agines, dissipate it. In Cooke’s admirable volume, “ Relig- ion and Chemistry,” he shows that the ultimate constitu- tion of matter, so far as modern physics have succeeded in unveiling it, bears abundant testimony that an All-Wise Intellect presided at its creation. Critics of various schools quibble upon the word “creation,” as they do upon the word “make”; but their pleasantries are di- rected against their own caricatures of theistic thought, and not against the thought itself. No intelligent Chris- tian supposes that any finite or human language can be adequate to express infinite realities. By saying that in- tellect presided at the creation of matter, he means that “Out of Thought’s interior sphere These wonders rose to upper air.” ‘“‘ Ever fresh the broad creation, A divine improvisation, From the heart of God proceeds, A single will, a million deeds.” Thought preceded, logically, if not chronologically, the formation of the elements. It is objected that creation never could have taken place in time, because that would imply a time before creation, when God dwelt alone; and creation would thus become an accident, a change in the THE UNIVERSE A WORK OF ART Tih Divine life; but the infinite and eternal cannot suffer change. And the reply of Christian theism is obvious: first, that we cannot argue safely from the infinite; and, secondly, that in this objection the infinite is not made absolutely infinite. Of course, the potentiality of all being lay in him; and nothing could come into existence which was not already in the abyss of potentiality with him, any more than lava could flow from a volcano were it not already in the caverns beneath. But this objection to creation, that it would make a change in the Divine life, forgets that changes are actually and incessantly occur- ring in the world. The eruption of volcanoes, for exam- ple, certainly takes place in time and in space. But the eruption of a universe out of potentiality into existence is, in respect to the infinite, no greater than an eruption of Vesuvius out of quiescence into action. In the very elements of matter; in the law of definite proportions by weight ; in the law of multiple volumes; in the peculiar quiescence of some of the most abundant materials ; in the alternation of perfect quietude and in- controllable fury, displayed by oxygen; in the value of both moods to human life; in the instability of nitrogen, and its consequent adaptation to form organisms, of un- stable equilibrium, as a residence for our incarnate spirits ; in the prevalence of polarities, producing definite crystal- line forms, marvellously exact in their conformity to geo- metrical law,— in these, and in various other peculiarities of inorganic matter, Professor Cooke shows that numerous lines of induction run together, and confirm beyond rea- sonable cavil the conclusion that, in the very constitution of matter itself, we have abundantly demonstrative evi- dence that it is the work of a far-seeing, wide-reaching 78 POSTULATES OF REVELATION Intelligence, immeasurably exceeding and yet including our wisest conceptions of geometric and physical fit- ness. Let us pause for a moment to consider a single one of these numerous evidences, the offices of water. At the average temperature of the surface of the globe, water is the most abundant of liquids. It enters largely into the composition of the rocks, and is held mechanically in the soil. It is more nearly a universal solvent than any other known liquid. The substances soluble, for example, in al- cohol or ether or in carbonic bisulphide, and not in water, are rare and infrequent in comparison with those which water will dissolve. It is through this solubility alone that sufficient mobility is given to the components of plants and animals to allow their psyches to guide the forces of the sunbeam in building up organic forms. Water itself also largely enters into those forms as a component. It is an almost universal law that bodies contract with cold, expand with heat. In some instances there is an apparent exception, just at the moment of passing from a liquid to a solid form. But there are two notable cases in which the liquid begins to expand by cooling while yet above the temperature at which it solidifies. One of these instances is found in bismuth, a comparatively rare metal, in which the exception to the law has not led to many results of interest. But, in the case of water, the excep- tion is well marked. It is found that water, when cooling, begins to expand while yet nearly eight degrees Fahren- heit above the freezing point. This exception has as yet been accounted for by no physical theory of the constitu- tion of matter in general or of water in particular. It stands out as an unmistakable and important exception to THEC UNIVERSE AX WORK OF2ART 79 what would otherwise have been regarded as an invariable law of nature; and this exception naturally leads to ex- ceedingly interesting teleological inferences. Water covers more than half the surface of the globe, and permeates in sensible quantity a large proportion of the surface which it does not cover. Besides its great function as a solvent of other bodies, thus allowing mobil- ity of parts and evolution of organic forms, water is the great governor, regulator, or moderator of changes of tem- perature. The organic life of the world requires a very nice adjustment of the temperature of the surface within narrow limits of variation. Two miles below the surface the heat is everywhere greater than plant or animal could bear. Four miles above the surface the cold is always too intense for life to be maintained. Between these exceed- ingly narrow limits of space the narrow limits of climate are to be maintained, else the earth becomes uninhabit- able. This balance of climates or temperatures is main- tained through the agency of water. A blast from the north sweeps down upon us, and the vapor in the air is condensed into rain or snow, giving out its heat into the borean air and bringing its temperature up nearer to the average. A breeze from the south comes laden with suf- focating heat, the snow or moist earth, or the summer foliage filled with water, takes away the heat, and pours out vapor in return. When a portion of the water in a lake has given out its heat to the northern blast, it is con- densed by cooling, and sinks to the bottom, sending up / warmer water to supply its place and to temper a new a portion of northern air. This process continues until the lake is chilled through to its depths, and brought down to about thirty-nine degrees Fahrenheit, where the proc- 80 POSTULATES OF REVELATION ess stops. The surface water cooled below that point ex- pands, and by this exceptional behavior remains on the surface, and shields the water below. Presently it freezes, makes a solid coating of ice over the whole; and a most intense and protracted winter can make that ice only a few feet thick. Beneath it lies the great body of the lake, still held at about forty degrees, except as the warmer bed of earth below may raise the lower portion, and send it slowly up to be cooled by contact with the colder strata near the ice. Now let us consider for a moment what would take place did water not thus form an exception to the general rule. The whole lake or river would then be chilled to the freezing point, and readily be frozen solid. The river would thus perpetually gorge and choke itself by bottom ice, and all winter be spreading new fields of ice over its adjacent intervales. No summer sun would have power to thaw out the bottom of the lakes nor of the largest rivers. Not only would all organic life within the waters become impossible, but the whole earth would be perpet- ually glaciated, and even the torrid zone be narrowed into a belt of alternate frost and vapor bath, so that terrestrial as well as aquatic life would disappear from the earth, Common sense can scarcely refuse to see, in this strik- ing peculiarity of water, in this one great exception to the universal law of shrinking by cold, in this standing — or, rather, perpetually flowing and reappearing — miracle, a strong evidence of fore-knowledge. The constitution of water was preadapted to the races of plants and animals which were to be placed upon the terraqueous globe. No objection, subtly drawn from the nature of infinity and from the impossibility of attributing to the Infinite Being THE UNIVERSE A WORK OF ART SI so personal an attribute as intelligent forethought, can prevent common sense from seeing, in this behavior of water, a testimony to the wisdom of God. This is, how- ever, but a single one of numerous instances brought for- ward by Professor Cooke and by others, to show that the original constitution of matter is planned in conformity with the design of bringing man upon the world. Each of these instances forms a strong argument. The com- bination of the whole is invincible. As Professor Cooke argues from the molecular and even from the atomic constitution of matter, so astronomers, geologists, and geographers show us that in the cosmical arrangements there is similar evidence of a wise adapta- tion of part to part. If the present condition of things came without forethought or plan, it certainly is such a condition as wise forethought would have produced. There is evidence, in the formation of the continents and in the direction of mountain chains, that the present obliquity of the ecliptic has remained substantially the same since before the earliest azoic era. Yet that obliq- uity is so exactly suited to the present condition of things that any considerable diminution of it would make the torrid regions uninhabitable from heat and the temperate regions uninhabitable from cold. On the other hand, any considerable increase of it would carry frost to the equator, and make the summers of the temperate zones unendur- ably hot. Similar circumstances, as has been shown by Guyot and others, would follow any considerable change in the form and position of the continents. The size and distance of the moon, and her effect upon the tides, and many other things of this nature increase still further the lines of induction leading to the same great conclusion. 82 POSTULATES OF REVELATION Most numerous, however, are the lines of induction which may be followed in the examination of organic forms. The etymology of all languages shows that the earliest observers and thinkers were impressed with the fact that an animal, and even a plant, may be considered as having organs; that is, instruments designed and adapted for effecting ends. That impression is still made upon every observer. Evolutionists of to-day, holding the most agnostic or even atheistic philosophy, express the facts of organic nature by using teleological language. They speak just as freely as any other writers of the object of the various modifications of vegetable and animal forms ; that is to say, they use the words, “object, ences and “purpose,” as the easiest way of expressing their per- ception of the uses and advantages of the modifications, The innumerable instances of the adaptation of means and ends in nature are most easily thus described. Now, we may, if we see sufficient evidence to lead us so to do, suppose that all these modifications were produced by the mutual relation and reaction and limiting effect of hered- ity, of variability, and survival of the fittest. But, if we do so, then it seems to me that the facts of nature should also lead us to maintain (with Professor Asa Gray and some other modern writers, and with Erasmus Darwin, the grandfather of Charles Darwin,—a man of great genius and learning, whose name is strangely overlooked and ignored by those who, through the grandson, have received some of his doctrines) that the variation and survival are, nevertheless, through pre-established lines, since the total result bears the marks of infinite wisdom and power,—the evidence of having resulted from the ordination of Eternal Wisdom. THE UNIVERSE A WORK OF, ART 83 Certainly, the whole series of organic forms and func- tions, whether taken individually, taken in their smaller groups, or taken in their total connection, is precisely of the same character as if it were the fulfilment of a plan,— a plan of all-comprehensive, unerring wisdom, using the resources of infinite skill and power. Spherical astron- omy treats, properly, only of the apparent motions of the heavenly bodies on the apparent interior surface of an ap- parent hemisphere or sky; but, in a certain treatise, the writer, after describing various apparent diurnal motions, sums them up by adding “precisely as if the earth were turning on its axis from west to east.” And this is the reason why the Copernican system is believed to be true, because it is thus in perfect accord with the appearances in the sky. When any hypothesis explains the facts which it was framed to explain, and is discovered also to explain other facts not known or not considered when framing it, the hypothesis rapidly becomes a theory; and that theory is, by the increase of the facts which it ex- plains, more and more firmly established as science. Now, the morphological and teleological arguments of theology make the hypothesis that the universe is framed and fashioned after an intellectual ideal of perfect wisdom, so that the parts are adapted to each other with infinite skill, to accomplish the fulfilment of the ideal. It is ad- mitted that we cannot grasp that ideal in its entirety. It is admitted that we can only partially judge of the adapta- tion of means to ends. It is admitted that we can see only a part of the ends, and that we may, therefore, some- times err in our perception of the uses of parts. But we certainly find, in the universe, abundant evidence of the presence of thought. The direct road from the high @ 84 POSTULATES OF REVELATION prior’ assumptions, which the teleological and morpholog- ical arguments make, leads back to many truths of obser- vation, not included in those from which the assumptions were made. For example, we have been led to assume that a God of infinite wisdom and power will not waste any force. Whatever he does will be done with the least possible expenditure of power. Now, it is a historical fact that, out of this purely theological statement, out of this reverent theological assumption of Maupertius, mathemat- ical writers have drawn as freely as from a horn of plenty. From it, as a premise, the mathematician deduces many laws of mechanics, which the physicist learns by observa- tion. The reader will doubtless recall the familiar in- stance of the optical laws, Light, in passing from point to point, through a medium of uniform resistance, would spend a minimum of force by going in the shortest path,— that is, in a straight line. Observation shows that light does move in straight lines. If we ask that the light, in passing through the uniform medium from one point to another, shall, upon its way, be reflected from the surface of a mirror, then the point of reflection must be so sit- uated as to make the total path of the incident and re- flected rays as short as possible. Calculation proves that the angles of incidence and of reflection must therefore be equal. Observation shows that they are equal. If the light goes through two media of different densities, then the path in the more difficult medium must be shortened, that in the easier lengthened, in such manner that the total force expended shall be the least possible. Calcula- tion proves that the sines of the angles of incidence and refraction must therefore be proportioned to the ease of motion in the media. Observation proves that they are sO proportioned. THE UNIVERSE A WORK OF ART 85 Again, look at the arrangement of leaves upon the stems of plants. Our theological conceptions would make us say that the wisdom, we might almost say the justice, of God would make him impress upon the plant a law by which the leaves should be evenly scattered around the stem, so that every leaf should have the fairest chance at light and air. The mathematician shows that this re- quires the successive leaves to divide the horizontal circle in extreme and mean ratio: the botanists show us this is the very law by which the leaves are arranged. This division in extreme and mean ratio was invented before the Christian era for purely abstract geometrical uses. Until the year 1849, no one was aware that it had been used in nature; but then it was shown to be embodied, not only in the plants, but in the arrangements of the solar system. Although the two instances are in such different regions of nature,—the one in the leaves of terrestrial plants, the other in the revolution of the ce- lestial bodies,— and even in such different regions of thought, the leaves dividing space in this ratio and the planets simply dividing time, yet the algebraical concep- tion is the same in both. The use also is similar in both cases. The planets are kept scattered like the leaves; and a heliacal conjunction of more than two is a rare oc- currence, frightening the astrologically timid only at rare epochs of time. The physical philosopher may justly object to the inju- dicious use of a grzorvt methods, such as brought contempt upon many of the ancient physical speculations, such as will probably, hereafter, bring contempt upon some con- temporaneous speculations. But he cannot justly object to a legitimate use of the method, as has just been shown 86 POSTULATES OF REVELATION by examples of what it can do, when judiciously handled. Those examples are striking, but they are not excep- tional. The mathematical method has been more easily applied, heretofore, to mechanical and cosmical problems ; but the same method is gradually extending itself into modern chemistry and physiology. All that is purely physical even in the human brain may be finally resolved into modes of motion, and must therefore, in the prog- ress of human knowledge, become more and more amen- able to mathematical treatment. In other words, that which is purely physical must become more and more purely ideal. With every step of that progress, hereto- fore, the teleological and morphological arguments have become firmer and more multiplied. The enormous num- ber of these consenting and consilient lines of ever- strengthening induction may be inferred, when we recol- lect how many treatises have been written in the mere attempt to enumerate them. The fulness of particular lines may be illustrated by a reference to the Duke of Argyll’s volume upon the wings of birds, or to Agassiz’s one hundred and thirty-seven inferences from the classifi- cation of the animal kingdom. There is no evading the overwhelming number and conclusive forms of these argu- ments, no avoidance of the conclusion that “there is one God,” and that “science is the knowledge of him.” There is no resisting the evidence of his infinite wisdom, his ab- solute foreknowledge from the earliest epoch of all that has since transpired, There is no resisting this joy-in- spiring, uplifting conclusion, except by methods which deny the validity of all reasoning, and destroy the possi- bility of ever resting in any conclusion or belief whatever. Taken as a purely intellectual proposition, the evidence of THE UNIVERSE A WORK OF ART 87 the being of an all-wise and almighty Creator of the uni- verse is as conclusive as the evidence of the being of our fellow-men, The world is not a machine, running independent of its Creator’s sustaining power; neither is it an organism of which He is the unconscious psyche: it is a perpetual, increasingly intelligible revelation of his divine wisdom, his unfathomable goodness, his eternal power. Men may err in their attempts to interpret it; but Bacon’s compari- son of final causes to vestal virgins, and Huxley’s coarser allusion to /etazrae, are as false to the history of science as they are disagreeable to modern taste. VI. POWER AND POSSIBILITY. THOSE who have ridiculed the arguments of natural theology have usually assumed that the teleological and morphological arguments were intended as a demonstra- tion of the wisdom of God. But, certainly, no theological writer of sound discretion has ever so misunderstood his own lines of thought. We could not demonstratively prove, from an examination of the external world, that the Creator is infinitely wise, absolutely unerring. We could not do this unless we were ourselves unerring in wisdom, unlimited in power, and examined the whole of a bound- less universe in every part. As it is, however, we obtain indefinitely great confirmations of our faith in the wisdom of God. Various lines of induction lead us toward the grand conclusions of faith in him; and reason shows that, in rising upwards toward a consideration of the source and origin of all things, we can find no rest for the in- quiring spirit except by faith in an infinite source,—a God infinitely and unerringly wise. It is a moral neces- sity in our own nature, which leads us thus to push through and beyond the indefinitely great,— thus to leap to and cling to the infinite. The same conclusion arises from a consideration of the Divine Power. The universe, in its actual manifestations of force, is indefinitely great. These forces imply still greater potentialities. And the POWER AND POSSIBILITY 89 mind will not be satisfied without the conviction that in the Being in which these powers abide there is a poten- tial abyss of infinite depth and capacity. We have already alluded to the rich fruits which math- ematical and physical science has gathered from fields covered by the principle of the least action—the dogma of theism that an infinitely wise God will waste no force. As it was from theology that mathematics and physics re- ceived this valuable, instructive, fruitful dogma, so it is to theology that they are still to look for limiting guides that may prevent their wresting it to their own destruc- tion, In the present day, when the domain of physical force has been so widely extended by brilliant experi- ments, and the induction that all manifestations of force, in space and time, are merely modes of motion, has been so firmly established, carrying with it the consequence that all forces are really correlated forms of one force, it is sometimes hastily assumed that the doctrine of the conservation of the ws vzva has been equally established as a universal truth. It is sometimes said that as the sum total of matter in the universe is constant, nothing being created and nothing being annihilated, so in like manner the sum total of force in the universe is constant, none being added, none being destroyed. It is said that all the forces in the universe are either being manifested as energy, or becoming potential as power; and that the universe, therefore, has been in motion from eternity, and will be in motion to eternity. | Yet for this form of the doctrine there is no distinct evidence; and it has been stated, by very high authority, that it can be shown to be mathematically impossible. Wherever we see matter in motion, not under the guid- QO POSTULATES OF REVELATION ance of organic life, it is moving toward a position of stable equilibrium, either statical or dynamical. By this phrase, ‘‘dynamical stable equilibrium,” we refer to such movements as those of the planets of the solar system. But a grave suspicion has been entertained that the lu- miniferous ether, or, perhaps, some grosser interplanetary matter, is slowly retarding the motions of the planets, so that these examples of apparently stable dynamic equi- librium would fail to give us assurance of an absolute per- petuity to the cosmos. The tendency everywhere is to move toward a final state of stable statical equilibrium,— a state indistinguishable by our imagination from a state of annihilation ; for a final, universal, statical equilibrium implies an absolute quiescence of all motion, a return of all force to the abyss of potentiality, a disappearance of every conceivable phenomenon. And this state is threat- ened by the universal phenomenon of cooling. The sun, for example, radiates his floods of light and heat. They may last millions of years, but they are not inexhaustible; they may be supplied by showers of meteors and comets falling into it, but that supply cannot be infinite: for all that physical science can see, the sun must finally be as cold and dead as the moon, Even should two dead suns fall into each other, the concussion would produce only a temporary, partial return of the heat; for all the energy that could be converted into new heat would be the force which is in the translation of the two cold suns. Whereas, at present, the suns have all that energy, and their present heat beside. The energy of that heat is radiated outward, from the universe as known to us, with a constant flow; and science knows no way whatever by which it can be restored. If, therefore, physical science POWER AND. POSSIBILITY OI believes in an eternal, physical universe, she must, in order to find any basis for her belief, leave the domain of physics and come into that of theology. Science her- self can Jead backward only to a wonderful fire-mist, fill- ing universal space; forward only to absolute zero, four hundred and sixty degrees below zero, Fahrenheit,— pitch dark at that. For any origin of that inconceivable en- ergy of pristine force, for any recovery from that total stagnation of utterly unimaginable cold and darkness wherein no physical forces will be manifest, she can turn only to the theological conception of God. Whether theology demands of us faith in the existence of a physical universe from eternity to eternity is, how- ever, a difficult problem, upon which there may not be an agreement among the deepest thinkers. Certainly, the Hebrew and Christian Scriptures seem to imply an absolute creation at a definite era of time, and an absolute destruction, at some future era, of the present existing universe. We have just said that purely physical science seems to point to the same conclusion. Yet, in those same Scriptures, the realities of the spiritual world are always represented in figures drawn from the natural world. Philosophy, speculating upon the same question, fails to perceive the possibility of any communication be- tween mind and mind, except through the medium of something perfectly analogous to matter. The authors of an ingenious little book, ‘The Unseen Universe,” en- deavor to show that there may be ethereal bodies bearing the same relation to our present material bodies that the luminiferous ether bears to the grosser fluids of the atmosphere and the ocean. The fundamental fault in their treatise is the apparent assumption that man can- Q2 POSTULATES) OF .REVELATION not exist without a body; and their argument for immor- tality only goes to the extent of saying that it is possible that we have an ethereal body which may outlast the material body by thousands, or perhaps hundreds of thou- sands, of years. This does not, however, satisfy the demand of pure reason, which shows that the soul of man, which reads and partially understands the lessons of external nature, is directly akin to the Eternal and Infinite Spirit which writes these lessons. Seventy thousand years is no nearer to the true immortality of the human soul than seventy. That soul does not de- mand a body in order to exist, but simply demands control over some form of motion in time and space, by which it may express itself to other minds. How nearly analogous that control of motion in the spiritual world may be to our control of motions in the material world is a question which probably can never be answered until we have passed beyond the veil. All researches into the constitution of the natural world. show that there is an intellectual connection of all the parts; that there is a unity of thought, even in places where we discover no unity of cause, unless we seek that unity of cause in the ideal connection existing in the thought which nature embodies. Thus there is an intel- lectual connection between the force of gravity, the ve- locity of light, and the velocity with which the wave on the vibrating strings of a harp runs up and down the wire. There have been writers in our own day who have admitted this manifestation of wisdom and skill in the co-ordinated movements of the universe, but who have found them- selves unable to admit that any mind, even that of the Ruler of the visible universe, could have the control of POWER AND POSSIBILITY 93 unlimited physical energy. Mill thought that, if we yielded to the arguments for the being of a wise and beneficent God, we must at the same time admit that his power was limited. His opinions on theology are curious evidences of the impossibility of utterly expelling the spiritual nature from a man, even by such an educa- tion as that under which his growth was cramped and distorted. The evidences, which he thought he detected, of limitation to the power of the Almighty, appear to us to have no weight. But, on the other hand, reason will show that there are limitations to the Almighty Power, which unreasonable men frequently overlook. Physical necessity, which to the common mind appears to be an absolute necessity, is, in fact, the weakest form of neces- sity. Logical necessity overrides it; and the highest necessity, moral necessity, reaches far above either of the other two. We rise by reason to the higher concep- tion of infinite power, which can manifest itself in any form of existence, in the creation of a soul or of a world. To such an Almighty Power there are, of course, no limits in the quantitative sense, else the power would not be almighty. But there are qualitative limits, which we are not to disregard in our speculations concerning God’s actions. For example, we cannot conceive that power has any control over the relations of space. It space be dependent on the infinite, absolute Being for its existence, it would seem to be simply this, that the divine omnipresence constitutes space. Space, therefore, could not be withdrawn into potentiality, even by infinite power. Again, neither reason nor imagination can conceive that even infinite power could make two straight lines enclose a space, or make commensurate the diagonal with the 94. POSTULATES OF REVELATION side of a square, or the diameter with the circumference of a circle. In like manner reason presents the existence and relations of time, as being independent of power. If time be dependent at all upon God, it seems to reason that it is dependent on his being, and not upon his will. In other words, it may be constituted by his eternity, but not by his fiat. Nor can we, in the most reverent frame of mind, admit that he could create a real period of time, either before or after the present in- stant. To such conclusions we are compelled by a necessity stronger than that of power; namely, logical necessity. Now, since space and time are thus independent of power, it follows that there must be things in the physical universe, also, which are out of the control of power. Force and energy are potentially unlimited in the will of God, and in actuality may be increased or diminished by him. But, inasmuch as physical forces are manifested by motion, and motion is manifested through space and time relations, physical forces must conform in their manifesta- tions to the laws of geometry and algebra, which are inde- pendent of power. Thus, of logical necessity, there arise physical impossibilities. There must be absolutely con- tradictory qualities in matter, as a function of space and time, which could not possibly be manifested in the same substance at the same time. When we enter the realm of spirit, the reason, even in its most reverent moods, recognizes the fact that there are also contradictories in spiritual things, absolute contra- dictories, so that it would not lie within the sphere of power to reconcile them. It is true that our sight in this realm is not so clear as it is in space and time. It requires POWER AND POSSIBILITY 95 sharper insight and more patient thought to see the high realities of the spiritual’ world. We may not, therefore, be able to point out spiritual instances of the limitations of almighty power so unmistakable as the incommensura- bility of surds in mathematics. Yet we may certainly say that a being cannot be properly conscious and unconscious of the same thing at the same moment; that it cannot hate and love the same thing at the same instant; that it cannot be morally free, and yet controlled in choice by physical necessity. In our theological speculations, there- fore, concerning the attributes of the Infinite Being, we are not hastily to assume that, because the Infinite One is almighty, he can do what is impossible. ‘With God all things are possible,” is a truth which has its own limi- tations. It is not possible for him to err, to be ignorant, or to be unjust. It is not possible for his power to effect what lies out of the sphere of power. And He alone knows, in all cases, what is within the sphere of power. He alone knows, also, what things within the range of power are best to be done. The in- ductions which show his wisdom confirm the decision of the higher reason, which runs beyond the conclusions of induction, and declares that the knowledge and wisdom of the uncreated First Cause must be infinite.
