This small volume contains the substance of a first course of Lectures, delivered in October and November 1872, in partial fulfilment of the honourable trust a few months earlier confided to me, after the lamented death of Professor Maurice. The subjects formally assigned to the Knightbridge Professor are Moral Philosophy, Casuistry, and Moral Theology. The first and third of these scarcely need any exposition of their meaning. The second was viewed by Dr Whewell as an historical term, now superseded by the more general and comprehensive phrase, Moral Philosophy. On the other hand Professor Maurice, while he looks on the solution of cases of conscience as impossible, applies the name of Casuistry to that subjective side of Moral Science, which enforces the claims of the personal "I," the individual conscience. This subject, though highly important in itself, does not seem to me, whether in history or by etymology, to answer to the name. But I think it may be transferred, by a moderate license, from doubtful VI PREFACE. and disputed questions in the details of Moral Duty, to Controversial Ethics, or the attempt to gain clear and firm convictions on those great questions, which give birth to rival schools of ethical teaching, and have perplexed and divided the judgments of moralists for thousands of years. The present work treats of three topics, all preliminary to the direct exposition of the first of these three main subjects, Moral Philosophy. These are the Certainty and Dignity of Moral Science, its Spiritual Geography, or relation to other main subjects of human thought, and its Formative Principles, or some elementary truths on which its whole development must depend. In the coming year I propose to myself to enter on the second subject, or Controversial Ethics ; by a review, first, of Modern Utilitarianism, as expounded by Paley and Bentham, and recast by Mr Mill into a different form ; and next, of mo- dern Cambridge Ethics, represented by the Discourse of Professor Sedgwick, and the writings of my three eminent predecessors. In Mr Mill's review of Professor Sedgwick these two schools came first into direct collision, almost forty years ago; and now in the present year, within a few months, these distinguished writers have both passed away. The harsher sounds of controversy should be stilled, and only its grave and gentle utterances be heard, over the recent graves of the dead. I have ventured to append to these Lectures a college essay or declamation, delivered in Trinity College Chapel PREFACE. vii in December 1833, or just forty years ago. I believe that the thoughts it contains, however youthful the style, are seasonable and important at the present hour. They secured at the time a favourable notice from Dr Chalmers and some other distinguished men. But I reproduce them here for a double reason. They are a pledge that the views held in the present volume, and others which may follow, are no hasty product of recent study, but convictions early formed, and deepened by all the study and reflection of so many years. Its date is just one year after Professor Sedgwick's Discourse, and a few months after its publication. It may thus be taken as one further sign of a reaction against the selfish and utilitarian school of ethical teaching, which had then set in, alike among older and younger members of the uni- versity, and which has continued to the present day, I commit this work, as a small sheaf of first-fruits, to the candid and forbearing perusal of learned readers; but still more to the blessing of Him, without whom nothing is strong, nothing is holy, the only Fountain of moral insight and true wisdom, the uncreated and eternal Goodness, in whom all truth dwells in its perfect fulness, from whom its streams proceed, and to whom they return, after watering the wide universe of moral being through which they flow. Trinity Parsonage, Camrridge, September, 1873. OF THE 'u'hiversitt; 4«: or ggy LECTUKE I. THE TRUE PLACE OF MORAL SCIENCE. In entering on the duties of the Knightbridge Pro- fessorship, I have endeavoured, in my Inaugural Lecture, to point out the great importance of the systematic study of Moral Science in the days in which we live. It is natural to begin this first course of Lectures with some remarks on the main outlines of the subject, and the order of treatment I hope to pursue. This seems doubly needful, when I succeed to writers so eminent as Dr Whe- well and Professor Maurice. They have left behind them, besides four volumes of published Lectures, a full and detailed History of Moral Philosophy, ancient and modern, and a systematic treatise on the Elements of Morality. And still they vary considerably from each other in their construction of the titles by which this Professorship is defined, and in their methods of ethical exposition. The original subject, by the deed of the founder, Dr Knightbridge, is "Moral Theology, or Casuistical Divinity." But when Dr Whewell, on his election in June 1838, revived the office from a loug and deep slumber, he introduced in his first Lecture the name B. L. 1 2 THE TRUE PLACE OF MORAL SCIENCE. " Moral Philosophy ", as well adapted, in his view, to express " the substitution of a newer form of science, full of life, hope, interest, and solid truth, for older and more imperfect speculations." " I shall reckon," he says, " on the implied sanction of the University, in considering myself as Professor of Moral Philosophy, a branch of study of which a Professorship exists, I believe, in every Univer- sity but our own." The sanction implied at first, was afterwards expressly and publicly given, when the Univer- sity made a later addition to the original endowment. Dr Whewell began with a course of Lectures on the English Moralists from Hobbes to Paley, Gisborne, and Price, at the close of last century. To these, when pub- lished, six others were added on Bentham's works ; and in a second edition, in 1862, fourteen others, which began with Plato and ended with Coleridge. His second and main work, published in 1846, was the "Elements of Morality," a full and systematic treatise on Moral Science. It was followed, the same year, by eight "Lectures on Systematic Morality," and appeared anew in 1864, shortly before his death, in an enlarged and revised edition. The Third Book of the Elements includes a full treat- ment of Ethics in their religious aspect, or Moral Theology. But Casuistry, in Dr Whe well's view, holds quite a secondary place in Christian Morals. It refers, he says, to "questions of human conduct, in which conflicting duties, or obscurity in the application of moral rales, perplex and distort the faculty which judges of right and wrong." It is thus "neither the main part" of the general subject, "nor that from which it can with propriety derive its name." Prof. Maurice, on the other hand, in his opening Lecture, seems to regard Casuistry, Moral Philosophy, and THE TRUE PLACE OF MORAL SCIENCE. 3 Moral Theology, as three distinct and successive stages of Moral Science, which fitly express its personal, social, and religious elements. He appears further to assume that these titles of the office are a guiding light, which the University itself has supplied, to fix the limitations of the main subject, and the due and proper order of its exposi- tion. He had published, twenty years before his election, an instructive treatise on the history of Mental and Moral Philosophy, and it has since appeared, in a revised and enlarged form, as his latest work. It was natural for him, then, to abstain in his Lectures from this branch of the main subject, and to confine himself to a more direct treatment of moral questions. His first course, accord- ingly, was on the Conscience, under the title of " Lectures on Casuistry," and his second on Social Morality. Had his life been spared, we may assume that a third would have followed on Moral Theology. But he remarks that he had found it impracticable fc> maintain entire distinctness, and that Moral Theology had really intruded into both. "It must be so," he observes, "for any one w T ho discovers, beneath the conscience which testifies of our personal existence, and beneath all the order of human society, a Divine foundation." Dr Whewell, then, has unfolded Ethical Science mainly on its objective side, as a connected and very extensive scheme of thought, under the heads of Springs of Action, Morality, Religion, Eights and Obligations, Polity and International Law. But in such an outline, however ably filled, there may be some danger of the conscience finding itself oppressed, like David in Saul's armour, by a panoply of solid and laborious thought, too heavy for its weakness to sustain. A treatment less com- plete and exhaustive, but appealing more directly to the 1—2 4 THE TRUE PLACE OF MORAL SCIENCE. spontaneous emotions of the heart, like arrows from the bow, or stones from the sling, must therefore have been desirable at least as a supplement for common minds. Prof. Maurice, accordingly, took up in his first course the subjective side of Ethics. He sought earnestly to bring out into full relief the "I ought " of conscience, to protest against theories which would resolve it into the mere dread of human punishment, and to summon it, by a direct appeal to the consciousness of its own supremacy, to the pursuit of high and noble aims. An awakened conscience, fully alive to the claims of duty, which looks up with reverence to a law it cannot alter and is bound to obey, is the first essential of true morality, the only genuine passport to the temple of ethical science. Where this is absent, learned speculations on moral theories, and on schools of ancient and modern thought, become im- moral trifling, bewildering to the reason, and deadening to the heart. m But while the subject of these Lectures is, I conceive, a most suitable and needful supplement to Dr Whewell's more systematic work, I do not think that they are "Lectures on Casuistry," either in the sense of the founder, or in the well-known and historical meaning of the name. The earnest inculcation of thorough conscientiousness in all cases, and under all sacrifices, is indeed of vital and almost supreme importance to the moral student. It is the starting-point of genuine progress, the living sap in the tree of Ethical Science. But Casuistry in its proper sense, or the provision of rules for the guidance of such a con- science in doubtful and obscure cases, is widely different. One is like the root of the fruitful olive-tree, the other is the gleaning berries on its outmost branches, when the harvest has already been gathered in. THE TRUE PLACE OF MORAL SCIENCE. 5 The threefold title of the Professorship may be adopted, I think, with less violence to the real distinctions of the subject, in another way, without disturbing their order, or using Casuistry in a sense wholly diverse from its historical meaning. Moral Theology, instead of being included, as in Dr Whewell's work, midway in the course, should be reserved, as the highest division, for the crown and climax of the whole. Philosophy deals with the conclusions of human reason, aided and enlightened by Revelation, but acting still within the limits of that Divine appeal — "Yea, and why even of yourselves judge ye not that which is right?" Theology deals with the character and works of God, as made known to us more clearly and fully by Divine revelation. And thus Moral Theology is the meet- ing-place and border province of these two kingdoms of thought. It deals with the religious aspect of Moral Philosophy, and the ethical aspect of Revealed Religion. It binds these together in a higher synthesis, where reason is ennobled and purified by faith in a Divine message ; while faith itself, cleansed from mere superstition, offers to God a reasonable service, and sees light in the light of heaven. Moral Philosophy, thus defined, must include the sub- jective and objective side of Ethics, the enforcement of the claims and supremacy of conscience, and the whole range of social morality; or, in one word, all the direct and positive teaching of Moral Science. What place, then, is left for Casuistry ? In the strict and proper sense, Dr Whewell justly regards it as a very subordinate branch of the general subject. The difficulties, also, to which it relates are more likely to seek and find their solution from the pastor or the friend than from academical lectures. And Professor Maurice, even while he retains the term, 6 THE TRUE PLACE OF MORAL SCIENCE. seems wholly to abolish the science or art itself, since he holds that attempts to lay down rules for cases of con- science " only leave those cases more unsettled than ever." But if doubts and questionings, in the present day, are mainly transferred from curious and involved cases, where the path of duty is obscure, to the very foundations of morality, we may come near to the true design of the founder by retaining the title in a somewhat varied sense. Casuistry will thus refer to the polemical aspect of moral questions, and deal with those controversies and disputes which tend to cloud and perplex the minds of students, and are constant attendants on every imperfect stage of a progressive science. I propose, then, to arrange the general subject under these three main divisions : 1st, Direct Ethics, or Moral Science in its relation to other sciences, its fundamental principles, and the wide range of personal and social obligations, in- cluding some first lessons of religious faith and duty ; 2ndly, Controversial Ethics, answering nearly to Casuistry, or the inquiry into the debateable ground of Morals, and the dis- cussion of rival and conflicting systems; and, 3rdly, Moral Theology, a wide and interesting, as well as difficult, field of thought. For here an awakened conscience and intelli- gent Christian faith act and react on each other. The con- science tests pretended revelations by laws of its own, while it submits reverently to the authority of a Divine message. It can thus learn new facts and lessons of God's moral government, grow more fully instructed as to its own nature and the duties and hopes of man, as responsi- ble to his Maker, and- walk in the light of a teaching higher and even purer than its own. Here, also, an intelli- gent, but sober and reverent, faith brings its unsolved and perplexing problems, in messages that claim a Divine THE TRUE PLACE OF MORAL SCIENCE. J origin, to be examined in the light of a purified reason, and to be solved even here, when the answer is possible, for our present comfort, and the due strengthening of its own powers. But when such a solution is too hard for present attainment, it is the further office of Moral Theology to remind us of the limitations of our moral insight, while we see "as in a mirror, darkly"; and to encourage us to wait hopefully, and not impatiently, for clearer light ; whether the blessing may be given in the world's eventide, or only in that brighter morning, when the day shall break on the immortal spirit, and the shadows of the night shall flee away. These few remarks on the conflicting definitions of Casuistry by the two most eminent of my predecessors, and their differing arrangements of the whole subject, seemed needful to explain and justify the order I propose to follow. My purpose, in the present course, is to treat of some first principles of Direct Ethics, or Moral Philosophy in its narrower sense, under these two heads : its relation, as in a moral geography, to other branches of human knowledge, and its fundamental principles, or the courses of solid masonry on which it rests below. And my first subject will be the True Place and real dignity of Moral Science. There is a school of thought, in our own days, which, under the boasted name of Scientific Progress, would wholly abolish all Theology, and reduce Morals to a dependent and precarious existence, in which it becomes the vassal and slave of Physics or Human Anatomy. And its strength, in popular esteem, has been derived, in no small measure, from its attempted classification of every de- partment of human science. The instinctive craving after unity, never wholly asleep, has been wakened into new 8 THE TRUE PLACE OF MORAL SCIENCE. and more intense activity by the discoveries of the last hundred years. Many run to and fro. The bonds of commercial intercourse are interlaced and strengthened. Nations learn thus to look beyond themselves, and re- cognize dimly a wider and larger brotherhood of all man- kind. The same influence extends to the mutual relations of the sciences themselves. The various branches of in- tellectual speculation and thought borrow from each other, and melt into each other, more and more. Thus Astronomy borrows from Mechanics, Optics, Electricity and Mag- netism, and even of late from Chemistry, the means for its further and wider progress. Geographical re- search becomes more exhaustive, and geological inquiry deeper, more profound, and more various than before. Both of these alike borrow largely from Zoology and Botany, and lend to these sciences rich and copious materials in return. Heat is identified with motion, and becomes a subtler branch of Mechanics. The magnet- ism of the earth has its changes linked with solar phe- nomena. Deep ocean soundings, made by new refine- ments of instrumental skill, modify geological theories. The same craving for comprehensiveness and unity reveals itself in antiquarian pursuits, and modern researches into the history of language and of race. It seems as if the limbs of Science, torn asunder by ignorance, and violently scattered, were striving to come together, and clothe themselves with sinews and flesh once more, and thus to form one living, united, and harmonious system. In such a period of thought, any school which pro- fesses to exhibit all the sciences in their orderly succession, and to ground on that arrangement special theories and deductions of its own, wields an engine of aggression on a.11 rival systems of no common power. The combat is THE TRUE PLACE OF MORAL SCIENCE. 9 like that between a regular army with its well-disciplined battalions, and guerillas or volunteers without discipline or concert, spread out in loose array. Such a theory has arisen, it is well known, in French Positivism, and, variously modified, has many disciples or admirers among the cultivated classes of our own land. But such a doctrinal system, which destroys and proscribes all religious faith, and degrades morality into a cerebral secretion, a blind necessity, or a pleasure- seeking prudence, can only be met and overthrown by one better and nobler ; by a system which retains what- ever is true and sound in the lower fields of thought, but includes in its larger geography those sacred heights and mountain-tops of human science, which deal with moral and spiritual objects, and pierce into the skies above, while they command the widest and most com- prehensive views of the peaceful valleys below. Let us begin, then, by endeavouring to fix clearly the true place of Ethics in the wide range of human science. And here the scheme of Lord Bacon, in his De Augmentis, supplies a basis, capable indeed of no slight improvement, but from which the remarks of Locke, and the fuller sys- tem of Comte, are really a retrogression and decline, rather than an advance to clearer insight, and a more perfect and comprehensive arrangement. The first division of human knowledge, Bacon has well observed, must be drawn from the threefold powers of the rational soul, which is the seat of knowledge. History belongs to the memory, Poetry to the fancy or imagi- nation, and Philosophy to the reason. But here two further remarks naturally arise. First, this division is common alike to every branch of human thought, just as breadth, in Geometry, coexists with the other dimensions IO THE TRUE PLACE OF MORAL SCIENCE. of space. It seems thus more natural and convenient, instead of separating History and Poetry altogether from the kindred branches of Philosophy, as Bacon has done, to make this distinction subordinate to the main objective divisions of Human Science. And next, in the case of Natural Philosophy, the registration of natural pheno- mena, which answers to history, and the invention of hypotheses and development of their consequences, which correspond to poetry, are properly quite subordinate to the branch of science to which those phenomena and hypo- theses belong. They form its materials, and supply the means for its further progress. Tables of observations, records of observed facts, registered stellar phenomena, and the successive theories of Ptolemy and Copernicus, of Kepler and Herschel, are thus the inseparable adjuncts of astronomical science. Science or Philosophy, as Bacon has well observed, receives its primary and fundamental division from its threefold object, " Deus, natura, homo." "It is convenient," he adds, " that Philosophy be divided into three sciences, concerning God, nature, and man." But when he has laid this clear and simple foundation, he proceeds at once, rather strangely, to deviate from the only true and natural arrangement. He distinguishes inspired Theology wholly from Philosophy, and reserves it for the last place at the close of his treatise, as "the haven and sabbath of all human contemplation." And yet he places Natural The- ology, as a separate branch, first in the three main divisions of Human Philosophy. Such a scheme has plainly a double fault. It severs Natural and Revealed Theology as widely as possible, making them form the two extremes of the whole system. But they are plainly mere subdivisions of the same grand THE TRUE PLACE OF MORAL SCIENCE. II subject. The contrast implied in the names does not extend to the truths themselves, but refers wholly to the different means by which our knowledge of them is sup- posed to be attained. And next, his plan involves a dis- turbed order of the three divisions themselves, which are not allowed to form either an ascending or a descending scale. The truer plan of arrangement, in this respect, which M. Comte has justly followed, is that of an ascending series. Natural Theology, in Lord Bacon's outline of sciences, should plainly be reserved for the third place, near the close ; so as to prepare the way, by a gradual ascent, for the fuller and higher teaching of Divine Revelation. Nor should this be excluded from Philosophy. It ought rather to be included in it as its highest and noblest portion. For the genuine pursuit of wisdom, which is the meaning of philosophy, can never rest short of the vision of the Only Wise, or that " knowledge of the Holy" (Prov. xxx. 3), which alone is true understanding and "life eternal." . Again, that "prima philosophia," which Lord Bacon places as the common stem of the three main divisions, seems to have no real claim to this high position. So far as it is real, and not a mere play on words, or on the analogies and ambiguities of human language, it be- longs to some aspect or other of Natural Theology, and the relations between the First Cause, the Creator, and the whole universe of created things. The first and main division, then, of Philosophy or Science is threefold. Its first and lowest portion is Na- tural Philosophy ; its second, Humanity ; its last and highest, Theology, both Natural and Eevealed. This, too, is the very order implied in the system of our ancient universities. It is far more full, harmonious, and complete, 12 THE TRUE PLACE OF MORAL SCIENCE. than the maimed and imperfect substitutes which have been proposed or invented in modern times. Natural Philosophy is divided by Lord Bacon into Speculative and Operative, and the Speculative into Physical and Metaphysical. The former of these is said to deal with the efficient cause and matter,] the other with the final cause and form. Again, the Physical is divided into three subjects, the Principles of things, the World, and the Variety of things. It is further divided into a doctrine of Concretes and Abstracts, the first having the same divisions as Natural History. The Meta- physical is divided into the doctrine of Forms and of Final Causes. Operative Physics, again, are parted into Mechanics, and Magic in a revised sense of the term. This, in Bacon's view of it, seems nearly to agree with the modern science of Imponderables, since he defines it to be "a practical knowledge of the more secret powers and subtle influences of the natural world." Last of all, Mathematics, both pure and mixed, are made a separate appendix of the whole. • Such an arrangement of Natural Science, it can hardly be denied, leaves on the mind a vague and confused im- pression. From the objective principle, clearly laid down at first, we are thrown back on subjective divisions of a wholly different kind, which are made to depend, in part, on the abstractions of Greek philosophy. What is called Operative Natural Philosophy really consists in the application of natural knowledge to the wants of mankind, and thus properly forms a part of the higher subject of Humanity. Lord Bacon seems to have known little of Mathematics, and, like Sir W. Hamilton, held them in light esteem. Instead of being made an accidental THE TRUE PLACE OF MORAL SCIENCE. 13 appendix of Physics, they ought rather to come first, as the intellectual starting-point and basis of the whole scheme. They are lowest, indeed, in dignity, though first in order of ascent, but still claim a very high importance, because their truths underlie every branch of Material Physics, and may thus be justly held to be the foundation of the whole. Mathematics, or the Science of Number, Space, Motion and Force, will thus hold the first place in the natural arrangement of the Physical Sciences. Next will come Uranology, or the knowledge of the heavens, and all the worlds they contain, whether suns, stars, planets, satellites, or meteors, star-dust, and nebulous matter, spread through the depths of space. Third in order will be Ecumeno- logy, or the knowledge of the habitable world, a subject in outward extent far more limited than the last, but also far more accessible, and thus capable, practically, of a fuller development, and of more various subdivision. It includes three main classes of objects — lifeless matter, plants, and animals or living things. The first may be called Hylology, and is either analytic or synthetic. Phy- sics, or Analytical Hylology, will include Solid Mechanics, Hydrodynamics, Pneumatics, the doctrine of the Impon- derables — Heat, Light, Electricity, and Magnetism — and analytical Chemistry, or the determination of the laws which distinguish the main classes of lifeless things. Geo- gnosy, or Synthetic Hylology, will include Physical Geo- graphy, Hydrography, Meteorology, and Geology; with two appendices of Palaeontology, or the determination of past changes, and the probable state of the Earth in every former age ; and a corresponding science, still nameless, and beyond the range of present human foresight, which would include the prediction of all future changes in distant ages still to come. 14 THE TRUE PLACE OF MORAL SCIENCE, Passing over the two higher divisions of Natural Philosophy, Botany and Zoology, we come to a higher subject, which holds the middle place in the ascending series, and to which the words of Pope will apply — The proper study of mankind is Man. The leading division in the Be Augmentis of Lord Bacon has here been reproduced by M. Comte under different names. The Philosophy of Humanity and Civil Science, in the former, answer very closely to Biology and Soci- ology. The first is parted by Bacon into a science of the Body and of the Soul. A third division is added, on the State of Man, or his Personality, and the union of body and soul. This, again, is made to include two parts, a doctrine of the Miseries, and one of the Prerogatives of Man. The Science of the Body is parted into four divisions, relating to health, beauty, exercise and pleasure, or a science of Medicine, Cosmetics, Athletics, and He- donics. The Science of the Soul is parted into one of the Substance and Faculties, and another on the use and objects of those faculties. This latter is divided into Logic and Ethics. Ethical Science is parted into a doctrine on the Standard of Good, and another on the Culture and Guidance of the Mind; and this last into three portions, on Character, on the Affections, and on Moral Remedies. Civil Science, again, is ranked under three main divisions. The first is the Science of Conversatiop, or Social Intercourse; the second, of Business or Occupation; and the third, on the Republic or Empire. To this brief outline are added two supplements, on the fountain of social right, and on enlargement of the bounds of empire. A simpler arrangement, I conceive, may be based on the ascending scale of human faculties or powers, and will THE TRUE PLACE OF MORAL SCIENCE. 15 thus be in closer harmony with the main objective di- vision of all science into Natural Philosophy, Humanity, and Theologjr. Humanity, or the Science of Man, in its widest sense will include the knowledge of Human Action, Speech, and Thought. Human Action will admit a fourfold distinction, with reference to the individual, the outer world, the family, and the state. These might perhaps be conve- niently styled Autonomics, or the discipline and culture of man's own person and bodily frame; Geonomics, including agriculture, horticulture, zoonomy, or the culture of animals, and navigation; Economics, or the science of domestic and family life; and External Politics, or the science of human action, when men are gathered in civil societies of various kinds. The Science of Speech will include Grammar, Lexicography, Oral and Written Lan- guage, Semeiology, or various modifications, used as signs of thought, such as Hieroglyphics, Stenography, Secret "Writing and Telegraphy; and the higher branches of Logic, Rhetoric, Dialectics, Education, Jurisprudence, Literature, and Public Worship. The Science of Thought will include Mental Philosophy in all its various aspects, and is either Analytic or Synthetic. The first refers to the different faculties and powers in each individual, and includes a doctrine of Perception and Sensation, or the relations of the mind to outward nature; of Reflection or Self-knowledge, of Sympathy and human fellowship, and of Religious Faith, aspiring to things unseen and eternal. The Synthetic Science of Human Thought is that which deals with the various characters and classes of mankind, and all the diversities of sex, age, race, intelligence, culture, and the countless varieties of human life and feeling, of social and religious thought. 1 6 THE TRUE PLACE OF MORAL SCIENCE. But a Science of Humanity, when pursued within these limits, does not satisfy the conditions of scientific completeness. For it deals wholly with the actual, and not the ideal. It contemplates Man as he has been or now is, and not as he might be or ought to be. But Man is conscious of powers of choice, on the use or abuse of which his happiness very mainly depends. He is not a mere tool or engine, set in motion by external powers, over which he has no control. He has a knowledge of good and evil, of evil which he seeks to avoid, and of good which he dimly seeks after, and longs to attain. He feels himself capable of progress and improvement, or of de- generacy and decline. Herein he feels himself to differ widely from lifeless matter, with its laws which it must obey, and even from all the lower animals, though these are gifted with wonderful instincts and powers of sponta- neous motion. And thus there remains a higher field, beyond and above all those branches of Human Science which have now been briefly indicated, and coextensive with their whole range. Man's nature is twofold. It includes the consciousness of actual powers and capacities, and the dim perception of a high and noble ideal, attain- able, but not yet attained. This is well expressed in the often- quoted lines — Except above himself lie can Erect himself, how mean a thing is Man! Humanity, then, since it refers to a being far higher in its powers than lifeless matter, or mere animal instinct, and still far below Divine perfection, resolves itself necessarily into two main divisions. The first is Actual Humanity, or the knowledge of Man such as experience proves him to be, in his various relations to nature, to his fellow-men, and to the Unseen Power on whom his being depends. THE TRUE PLACE OF MORAL SCIENCE. \J The second is Ethics or Ideal Humanity, the knowledge of that high standard of perfect action, speech and thought, below which men may fall continually, and too often with a deplorable and melancholy contrast, but towards which they are bound ever to aspire; and, aspiring towards it with earnest desire and effort, may hope for its fuller and fuller attainment. Ethics, then, in one word is the Science of Ideal Humanity. It sets before us Man, not as he is, but as he ought to be. It implies a standard of right and wrong, which does not depend on the actual state and conduct of mankind, and is not fixed by past experience, but which shines out amidst the storm-clouds of human passions and vices like a rainbow of hope and promise, pointing onward to something bright, excellent and glorious, not yet at- tained. This science of Ideal Humanity is the true main- spring of all human progress, which really deserves the name. And it forms also the natural transition to the best and highest field of human thought, Divine Theology. The connection is no mere result of fancy, or philosophical reasoning. It is inwoven into the very texture of Christian faith. For this is the grand " mystery of godliness," on which the whole fabric of the Christian revelation depends, that the ideal Man is no other than the Incarnate Son of God. A clear view of the main outlines of human know- ledge, and of their mutual relation, will thus enable us not only to ascertain the true place, but to maintain the dignity, of Moral Science. The arrangement of Lord Bacon is in this respect very faulty and imperfect. It would lead us to suppose that Ethics are a mere sub- division of one subdivided branch of the doctrine of Humanity ; that they come nearly midway in its course, B. L, 2 1 8 THE TRUE PLACE OF MORAL SCIENCE. and form hardly one-tenth of the whole. But this is wholly different from the real truth. They constitute a vast and wide field of thought, conterminous with the whole range of actual human knowledge. Throughout all the wide expanse of human interests they prescribe a standard of perfection to the actions, words, and thoughts of men, towards which they are bound unceasingly to aspire. Ethical Science is no mere product and corollary of man's past experience. It is rather its needful antidote. Its motto is evermore " Excelsior." It never permits this standard to be torn from the staff, and trailed in the mire of human corruption. It calls unceasingly on the corrupt and the impure to awake and arise. Amidst the strife of parties, the speculations of false philosophy, and the seductions of sensual vice, its clear and solemn voices are heard continually in such utterances as these : " Thou shalt not follow a multitude to do evil." " Speak to the children of Israel that they go forward." " What- soever things are lovely, whatsoever things are of good report, if there be any virtue, and if there be any praise, think on these things." This view of the true place and correct definition of Ethics as the Science of Ideal Humanity agrees closely with some striking remarks in Professor Grote's Exami- nation, a posthumous work, full of careful and suggestive thought. "There is no moral logic which will teach us to con- clude what should be, in the great features of it, from what has been, and what is. If we do so conclude, it is in a manner which destroys all our moral being. Man has improved as he has, because certain portions of his race have had in them the ideal element, have been unsatis- fied with what to them at the time has been the positive, THE TRUE PLACE OF MORAL SCIENCE. 19 the matter of fact, the immediately utilitarian ; have risen above the cares of self and of the day, have been imagi- native in thought, enterprising in action, deep and earnest in feeling.... If what Mans experience teaches him is to give up the imaginative, the deep and unsatisfied thought- fulness, the desire to penetrate to the reason of things, the hopefulness of becoming a worthier and higher crea- ture; if it teaches him to be content with the idea of knowledge as the registering of facts, and as what, rightlv used, may benefit his material condition — he will, I think, cease to improve. If he had acted on this principle from the first, he would never even have begun to improve." Two distinct charges may be brought against Ethical Science, as thus defined. The first, that it must be un- practical, dreamy, and Utopian. The second, that it is barren and inoperative, confined to a few popular truths, and incapable of real progress. Professor Maurice has remarked, in the opening of his first lecture, — " If the moral teacher adopts the distinction which is sanctioned by one of the ablest and most accom- plished of his class — that his business is with what ought to be, that of other students with what is, can there be a clearer or fuller confession that he means to leave the actual world for some other world which he has imagined?" And again, in the third lecture, after naming Sir J. Mackintosh as the source of the quotation, he resumes, " The distinction was plausible in itself, even without con- sidering the authority from which it proceeded. Yet if we accepted it, Ethics seemed transferred from the real world in which we dwell to some other imaginary world. In this case I am sure we should get no serious attention for them in this busy, practical age. Dismiss- ing, therefore, this opinion, without examining what might 2—2 20 THE TRUE PLACE OF MORAL SCIENCE. be the arguments for it, we asked whether there was no other difference between this study and those with which we are engaged elsewhere.... The Moralist cannot be less immediately occupied with that which is, with existing facts, than any physical student. His business cannot be carried on in some distant Atlantis, nor can he be en- grossed in the search for one." In passages of this kind it is not always easy to know whether my predecessor merely describes the probable feelings and impressions of others, or adopts them for his own. But it seems a cause for regret that there should be no formal censure of an inference, which, if actually drawn, would be one of the most inexcusable follies into which this busy, practical age could possibly fall. Ethical Science may be safely neglected, and in such an age is sure to be neglected, if it deals, not with what is, but with what ought to be ! Now the true sense of the definition is plain. Neither Sir J. Mackintosh nor any other moralist of common sense could ever be sup- posed to mean that the business of Moral Science is to quarrel with God's constitution of the universe, or to copy the traditional blasphemy of Alphonso of Castile, who said that he could have taught the Creator how to frame a much better and more perfect world. Moral Science, it simply affirms, teaches us how men ought to act, not how they have acted in time past, are acting now, or may, with more or less likelihood, be expected to act in time to come. It deals, of course, with the actual conditions and circumstances of human life. But still its proper work is to teach what human actions ought to be, not what they have been or are, in all the countless relations they fulfil to each other, and to the great Author of their being. Such is plainly the meaning of Sir J. Mackintosh, in the THE TRUE PLAGE OF MORAL SCIENCE. 21 words of his brief definition. They involve no confession, whether clear or obscure, of a purpose to forsake realities, and to speculate principally on some distant and imagi- nary world. Should a busy, practical age turn away from them, and justify its conduct by such a plea, our first duty, as moralists, is to expose the misconception, and point out the mischievous folly of the practical result to which it leads. It is just in proportion as any age is really practical, that the maxim has the highest claim on their notice and their reverence. For it reminds these busy, practical men, that the world in which their lot is cast is not as it ought to be, because they themselves, the moral agents by whom it is peopled, are not doing as they ought to do. There is a certain sense, it is true, in which the maxim does labour to transport men from the actual to an imaginary world. Only that other world is no fabled Atlantis, no unknown planet, governed by laws which human fancy has devised, and forming a part of some unknown system. It is our own world, changed and trans- figured by a moral renovation, when a pure and noble ideal of thought, speech, and action, shall once have been deeply and abidingly implanted in the hearts of men. Its nature has been well and clearly expounded by our Christian poet, — for a world, in principle as chaste As this is gross and selfish! one in which Custom and prejudice shall bear no sway ; That govern all things here, shouldering aside The pure and modest Truth, and forcing her To seek a refuge from the tongues of strife In nooks obscure, far from the ways of men! Morality is thus an intensely practical science, and 2 2 THE TRUE PLACE OF MORAL SCIENCE. claims the most eager and earnest attention in a practical age of busy men, for this very reason, that it exhibits before their eyes a lofty ideal of right conduct in all the relations of life, which it is our bounden duty, every day and every hour, to strive more nearly to attain. It admits, in accomplished facts, or in the voice of numbers and the clamours of a multitude, no excuse whatever for selfishness, vice, and crime, but reminds men solemnly what they ought to be, and the high standard they ought to keep ever full in view. But ethical study, if it escapes the charge of being dreamy, unreal, and Utopian, is exposed to a kindred reproach, that it is barren in all results, stationary and unprogressive. Thus we read as follows in a work of some reputation : "Though moral excellence is to most persons more attractive than intellectual, it is far less active, less pro- ductive of real good. The efforts of the most active philanthropy, the most disinterested kindness, are short- lived, and rarely survive the generation which witnessed their commencement.... There is nothing to be found in the world which has undergone so little change as the great dogmas of which moral systems are composed. To do good to others, to love your neighbours as yourself, to forgive your enemies, to restrain your passions, to honour your parents, to respect those who are set over you — these, and a few others, are the sole essentials of morals. But they have been known for thousands of years, and not one jot or tittle has been added to them by all the sermons, homilies, and text-books, which moralists and theologians have been able to produce." Moral Science, if these strictures are just, consists of little more than half a dozen sentences, known for thou- THE TRUE PLACE OF MORAL SCIENCE. 23 sands of years, and containing maxims which very few- have cared to practise. These maxims are incapable of any real addition, and have also exercised a very slight influence on the welfare and happiness of mankind. Physical Science, it is affirmed on the other hand, consists of an immense body of truth. It is cumulative and pro- gressive in its nature, and has grown constantly from age to age. And thus we may reasonably hope that it will conduct mankind by a surer path than mere moral teach- ing, and with a more effectual guidance, to some distant goal of social happiness and well-being. Now if it be meant simply to affirm that the first principles of Moral Truth have been known long ago, the same is clearly true of arithmetic, mechanics, and geo- metry. Yet their progress has been as real, and almost as conspicuous, as that of the Physical Sciences which depend upon them. On the other hand, if it be affirmed that simplicity and permanence, in general laws, forbid any development of the various results to which they lead, the facts of modern astronomy offer the paradox a decisive refutation. The moral law, which enjoins the love of our neighbour, is hardly more brief, and certainly not much more simple, than the law of gravitation. Yet the ablest analysts and geometers, for two hundred years, have tasked their powers to the utmost in tracing out the results of Newton's great discovery. And still they are very far from having exhausted the mine of its intellectual treasures. In binary stars, in asteroids and planets once unknown, in comets and meteorolites, in lunar disturbances, and tidal retardation, new discoveries reward their efforts from age to age. And after all their labour, the problem of three bodies, one of the simplest that can be proposed, defies their attempts at 24 THE TRUE PLACE OF MORAL SCIENCE. a perfect answer, and can be solved only under favour- able conditions, and by gradual and successive approxi- mation. Why, then, should Moral Axioms be less fertile than the Laws of Physics in the results to which they lead? The field is higher and nobler, and the capability of large development, on every ground of reason, is just the same. If mankind at large were half as zealous in the pursuit of moral excellence, as astronomers have been, since the days of Newton, in their calculation of attractive forces, and their practical study of the heavens, a thousand years would not suffice to exhaust the various develop- ment of the great laws of social duty, or bring to a close their progress in moral insight, and their successful labours of thought, and practical endeavours in this higher field. Once let us see clearly the true place of Morals in the grand series of the sciences, and these censures aimed against them by authors who may be clever in their own pursuits, but are sorely wanting in moral discernment and true wisdom, will drop away like withered leaves, and disappear. A science, of which the very aim and purpose is to discover and enforce the true ideal of right feeling and right action for every moral agent, and for each in- dividual of mankind, cannot possibly be barren aud worth- less, or devoid of practical power. It must be, from its very nature, of high and inestimable worth. Spurious counterfeits, indeed, may be not only unprofitable, but most mischievous. But surely a lofty and pure ideal of thought and action can never be set before the eyes of men, even in the most corrupt age, and the most de- graded state of society, wholly in vain. If such truths, plainly taught, and such high aims, held up before their THE TRUE PLACE OF MORAL SCIENCE. 25 eyes, were to be barren of all results, then assuredly, in the words of Milton, — The pillared firmament is rottenness, And earth's base built on stubble! It is quite conceivable, however, that the mode of operation of such truths, and the amount of influence they exercise, may wholly elude the notice of keen-eyed worldly men, or even of clever essayists and philosophers, intent on physical research, or buried in the strife of parties in the political world. There are tens of thou- T» sands who feel the steep ascent of a hill-side, or even the "^weight of some slight burden they carry in their hand. But who has felt, or feels at this hour, that mighty force of solar attraction, which has been unceasingly at work, on the largest scale of dynamical energy, through succes- sive ages ? Yet this alone has kept our earth stedfast in its orbit, and hindered it from losing itself long ago, with all its inhabitants, in outer darkness. When the stern and grand old prophet stood on Horeb, on the mount of the law, it was not in the earthquake and the fire, the wind and the storm, that he recognized the special signs of the Divine presence. It might have been known and felt there also, but it was found and felt chiefly in the still small voice alone. In nature those in- fluences are the most penetrating and powerful which escape the gaze of the superficial observer. There can be no doubt, either to calm students of human history, or to firm believers in Christianity, that the practical influence of great moral truths, in all past ages, has been grievously hindered, and often neutralized, by the moral dulness, or the vicious and sinful perverseness, of the greater part of mankind. They have been too often like dews alighting 26 THE TRUE PLACE OF MORAL SCIENCE. on the rock, or seeds that are sown on a barren and un- grateful soil. But it would be a fatal and immense error, on this account, to imagine that their publication, their ceaseless iteration, and earnest enforcement, whether by moralists or divines, have been wholly in vain. When- ever the thoughts are turned to them, the dullest con- science is in some degree stirred and aroused. The coldest heart is either touched with a secret pang of remorse, or kindled into dim and secret longing after a higher life. The weak and irresolute are awakened from the sleep of useless indolence, and nerved for conflict with temptation. The trance and stupor of sensuality is disturbed or broken. A voice — What meanest thou, sleeper ? awake and arise ! startles the truant conscience in its guilty wanderings. A breath of heavenly life seems to visit and breathe on the moral being, like the change which comes on all the face of nature in the first days of spring. Such emotions, indeed, when left to themselves, may quickly expire, and the coldness become greater, the dark- ness deeper than before. Some higher power is needed to sustain the awakened spirit, to keep it from relapsing into double apathy, and to guide its steps along the steep hill-side of heavenly truth. When the brightness and beauty of a high moral standard has dawned on the feeble and tempted spirit, the first impulses of awakened thought need to be sustained by prayer for Divine help, and the hand to be stretched out eagerly, to meet the proffered succour of heavenly grace. The parting words of Milton in Comus will then be found to be no mere utterance of a sportive fancy, but the veiled expression of the deepest philosophy, and of the highest lesson of Christian faith — a faith and a philosophy far more profound than modern theories for manufacturing some miserable sem- THE TRUE PLACE OF MORAL SCIENCE. 2 J blance of a conscience out of the transmuted instincts of the ape or baboon : — Mortals, who would follow me, Love Virtue, she alone is free : She will teach you how to climb Higher than the sphery clime : Or, if Virtue feeble were, Heaven itself would stoop to her ! LECTURE II. THE CERTAINTY OF MORAL TRUTH. Ethics is the Science of Ideal Humanity. It is no mere subdivision of one secondary and limited province in the wide domain of human thought. It is rather like that blue firmament, which is above us and around us wherever we go, and encompasses the lofty mountain summits and the lowly valleys of earth on every side. Its aim is to teach men, in every various field of thought and action, what they ought to be, how they ought to live, and what they ought to do. It claims to preside over all their converse with the world of nature, and the conduct of their inner life, their relations to their fellow- creatures, and their duties of prayer, praise, trust and worship, towards the Supreme Creator. In width of range it must thus be coextensive with all the various and countless fields of human thought, speech, and action. In dignity it rises above them, and surmounts them all. They set before us man as he is ; Ethics, man as he ought to be. They unfold his actual powers, habits, tendencies and dispositions. The science of Ethics sets before him a pure and lofty ideal, of good which he ought to seek, of moral beauty and perfection which he should ever strive to attain. Its lessons, when fully learned, show him how far he has come short of this high standard, which his own conscience, when thoroughly awakened, is compelled to approve. And thus it leads THE CERTAINTY OF MORAL TRUTH. 29 him by the hand to that footstool of revealed mercy, where heaven stoops to the feebleness of human virtue, or even to the degradation of human vice and folly, and with sovereign power raises up the lost and guilty to holy blessedness without measure and without end. But here, at the entrance of our inquiry, a great stumblingblock lies in our way, and needs to be removed. Have Ethics any just claim to be a genuine science ? Is certainty, on moral questions, possible or attainable ? Do we not rather enter here on a dark path, a thorny jungle of barren strifes of words, and tedious disputations " never ending, still beginning," and renewed with a wearisome and fruitless pertinacity from age to age ? The past history of mankind at large, and the known course and cycles of moral speculation, tend to strengthen these doubts, either of the reality, or else of the attain- ableness and practical worth, of ethical science. The fact is undeniable, which Locke has made so prominent in his reasoning against innate ideas (Bk. I. ch. 3, § 9), that a low and corrupt, sometimes a most repulsive rule of con- duct and practice, has often prevailed in whole tribes and families of mankind. Again, warm and earnest de- bates on the foundations of morality, and its primary laws, were transmitted from the clearest and keenest in- tellects of Greece to those of Rome. They remained still under ceaseless discussion for five centuries, until Chris- tianity replaced them by other questions of a still deeper kind. At the revival of learning after the middle ages, the flames of these ethical controversies, which had smouldered so long, broke out anew. And now, for more than three centuries, moralists and divines have rivalled the ancients in the zeal with which they have espoused conflicting 30 THE CERTAINTY OF MORAL TRUTH. theories. The strife, almost as keen and eager as in the days of Zeno and Epicurus, has lasted even to the pre- sent hour. How is it, again, that when Physics have advanced with such giant strides, the students of morals, by the confession of some of its ablest writers, should hardly change their ground? Are they not still renewing the same questions, which occupied youthful disputes in the days of Socrates and Plato, more than two thousand years ago ? " There is no study," says Professor Grote, " more uni- versal than Moral Philosophy. And yet, as a science, it cannot be said to have a high reputation at present in our own country. Nobody expects to learn much from what professes to be Moral Philosophy, or seems to think that much can come of it. This carelessness arises from a sort of notion that it is very likely to be mere words, or else a sort of quackery, very likely not to take hold of human nature, but to rest in useless generalities . . . Others are jealous of it, on account of its supposed tendency to level, regulate, and square human character, destroying its nativeness and variety; while those who are disposed to levelling and regulation are not in general interested in human philosophy of any kind." These prejudices against the study, from the moral diseases and confusions of the world, the endless disputes of moralists, and the seeming absence of real progress, gain double strength from causes peculiar to these times. The wide spread of a school of thought, which denounces Theology as an impossible science, casts its dark shadow over Ethics also. It tends to degrade it into a secondary branch of physiology, dependent for its very being on the growth and progress of anatomical science. The advance THE CERTAINTY OF MORAL TRUTH. 31 of Physics in all its branches, and the many inventions with which it has enriched and adorned human life, bring out into greater prominence the seeming absence of similar progress in what claims to be a higher and nobler field of thought. The restless activity of a bustling age spreads around men a close and stifling atmosphere, like the fog and smoke which settle down on our crowded cities. High and lofty truths from the upper regions of thought seem often to strive, almost in vain, to penetrate this thick gloom. There can be no wonder that, in such an age, ethical science should often be exposed to silent neglect or open scorn. In a Christian church and nation it might naturally be supposed that the clearer light of moral truth, found in the pages of a Divine message, would more than compensate for other causes of neglect and decay; and would secure for morals their due place in the intellectual culture of the age. And this is doubtless true within certain limits. The Decalogue and the Sermon on the Mount, with their popular expositions, have kept before the eyes of our people a standard which heathen nations never attained, and have secured a very wide acceptance for the simplest and plainest elements of Christian mo- rality. But even this great gain, through human infirmity, has not been free from some attendant loss. The higher doctrines or deeper messages of Christian faith have not seldom been so abused as to deaden the general interest in the great lessons of Christian and revealed morality. Nay, even the fact that great moral precepts have been plainly revealed, and have been received in name by every Christian, may turn to a hindrance of all activity of moral thought. It may quench, instead of quickening, the thirst for a fuller knowledge of the grounds on which those 32 THE CERTAINTY OF MORAL TRUTH. precepts are based, of their various harmonies, their count- less developments, and innumerable applications. There is still another way in which the evidence of moral truth may have been clouded and obscured by its connection with the cause of Christian orthodoxy. Some of our ablest Divines, in maintaining revealed religion against assailants, have insisted strongly on the duty, in matters obscure and uncertain, of resting satisfied to act on probabilities alone. Thus Butler begins his Analogy with a laboured argument, to show that even a slight excess of evidence, in questions highly uncertain, may determine practically what course it is right to pursue. But however true in the abstract it may be, such a line of defence must needs exercise a depressing influence on minds really athirst for truth. It is very apt to give them the impression, that the being of God, the person and work of Christ, the atonement, the resurrection, and the life to come, are looked upon as having only a slight excess of evidence, if any, over opposite falsehoods. They may thus be tempted to infer that the scales of faith and no-faith tremble in an almost even balance, so that confi- dent faith is only just one degree less foolish than confi- dent unbelief. Such an opinion must act like a palsy on all the nobler instincts of the Christian heart. It must surely have been a firm, deep, and hearty conviction, far unlike this timorous, hesitating, moonlight faith, by which the Apostles turned the world upside down, and overcame the might of the heathen empire, and martyrs poured out their very life-blood in defence of the truth. This cautious, defensive line of thought, which Butler and other writers have employed in their advocacy of revealed religion, has naturally affected the kindred THE CERTAINTY OF MORAL TRUTH. 33 subject of morals. They insist strongly on the practical obligation of being guided by the slightest excess of seem- ing probability. The want of fuller evidence is said to afford scope and opportunity for a virtuous exercise of the understanding, and to dispose the mind to rest satisfied with any evidence that is real. In such remarks there is a dangerous tendency to canonize doubt and uncertainty, and consecrate dimness of moral vision, as if they formed a useful moral discipline for Christian men. To seek and long for clear light in moral inquiries has sometimes been even discountenanced and condemned, as the mark of a sceptical spirit. But this is a dangerous inversion of the real truth. Such a desire, there can be no doubt, needs to be tempered with modesty and patience. There ought to be a willingness to be guided by moonlight, or even by starlight, until a clearer day-break shall arise. But still "light is sweet, and a pleasant thing it is for the eyes to behold the sun." The desire in itself is the healthy, inseparable instinct of an earnest mind and a Christian heart. It must be owls and bats of the moral world, and not the sons of light, who find it easy and natural, in the high matters of faith and conscience, to rest content with the dim twi- light alone. Let us now inquire whether these four difficulties, which seem to beset the approaches of Moral Science, will not disappear on a closer view. First of all, the objection from the low standards of moral feeling and practice in savage tribes, from the re- volting usages which have sometimes prevailed, and the great amount of vice and immorality even in Christian lands, can have little or no real weight with thoughtful men. No sensible person, certainly no Christian be- B.L. 3 34 THE CERTAINTY OF MORAL TRUTH. liever, can suppose for a moment that a perfect science of morals can issue forth, like Minerva from the head of Jupiter, complete, full-grown, and fully armed, from the mind and heart of the ignorant, the sensual, and the profane. Every science, however sure in its principles, or fertile in its results, needs first of all to be learned. To learn requires not only some natural capacity, but attention, seriousness, and diligence. Ethics are a law of duty. How can it be learned by those who are reckless of duty, and care chiefly or only for animal pleasure ? They are a light shining from above. How can it be seen by those whose eyes, like those of Mammon, are " always down- ward bent" upon the pavement below? In the field of moral inquiry more is required of the willing learner than in the walks of physical research. Moral, as well as intellectual conditions, need here to be fulfilled. There must be a serious desire to learn and know the truth, however humbling to our pride, and how- ever unwelcome to our indolence its lessons may be. Yet even in Physics, and in an age mentally so active as our own, how small is the number of those who obtain real scientific insight, compared with those who receive with implicit confidence the conclusions in vogue, from time to time, among scientific men. Let some feud arise amongst the known students and leaders in any science, and nearly all the seeming knowledge of these multitudes, being nothing more than opinions taken on trust from others, would quickly disappear. Moral Truth, to be received and held firmly, needs an upward eye, and an open heart. Such is the voice even of natural reason alone. But Christianity lays a double stress on these necessary and indispensable con- THE CERTAINTY OF MORAL TRUTH. 35 ditions of all moral insight. "If any one be willing to do His will, he shall know of the doctrine, whether it be of God." "If thine eye be single, thy whole body," i.e. thy whole intellectual being, "shall be full of light." Once let us read the history of the moral aberrations in the world by the light of these true sayings of Scripture, and neither the parricide, infanticide, and cannibalism, of heathen tribes, nor the licentious vices, the drunken intemperance, which defile and dishonour Christian nations, will lead us to question the certain attainableness of moral truth. The proverb of Solomon will supply a brief and full answer to such causeles,s doubts: "Evil men understand not judg- ment, but they that seek the Lord understand all things." Humility, joined with earnestness and diligence, is the portress which alone can unlock the gates, and open our way to the temple of Moral Science. The disputes and controversies among moralists them- selves are a far more specious objection to the claim of Ethics to be deemed a genuine science. How can certain truth be attainable, where there seems to be neither harvest-field nor vineyard of ingathering, but only a battle-field of ceaseless debate ? The triangular duel of the Academician, the Stoic, and the Epicurean, has lasted for twenty-two centuries. Slightly varied in form, it continues to the present hour. The morality of sentiment stands opposed to the moralities of reason. A morality, apart from consequences, the cate- gorical imperative of pure reason, fights with a morality reasoned out from consequences and results alone. How shall the disciples attain certain truth, when the leaders of thought, from age to age, seem to be in hopeless discord? It is the saying of Professor Grote, that "when we come to morals and ethics, the dust and smoke " common to other 3—2 36 THE CERTAINTY OF MORAL TRUTH. parts of philosophy " become tenfold worse." How should we look for peaceful certainties amidst the confused war- cries of a battle-field ? Silent inter arma leges. The reproaches of unbelief against the various sects and divi- sions of Christianity seem applicable, with equal force, to impeach and annul the claim of Ethics to be a real science. The answer to this objection, with a little patient thought, is not hard to discover. In every science there are some first principles, which are the starting-point or the foundation of all its other truths. These later truths form the pathway to which it leads, the building reared on that foundation. Now in every case these first principles, because they are the first, border on mystery, and lose themselves in the unknown. " On what does the earth rest ? On the back of a huge elephant. On what does the elephant rest ? On the back of a huge tortoise. On what does the tortoise rest ? Ah ! that, said the Indian, I cannot tell." This Eastern tale or parable may be applied to the foundations of every science. A well-known and able writer has laboured to show, in the opening of one of his chief works, that the Ultimate Keligious Ideas and the Ultimate Scientific Ideas are alike "unthinkable." By what strange leger- demain of thought the conclusion is reached, that Religion alone is mystery and nescience, and Physical Science a field of knowledge and progress, it is hard to understand. The difficulty is plainly common to both subjects, the natural on one side, the moral and religious on the other. The solution, so far as a solution is possible here, must be exactly the same for both. The striking words of Hooker apply here in all their force and beauty. M The goodliness of houses, the stateliness of trees, when we THE CERTAINTY OF MORAL TRUTH. 3 J behold them, delighteth the eye. But that founda- tion, which beareth up the one, — that root, which minis- tereth life and nourishment to the other, is in the bosom of the earth concealed. And if at any time it be needful to search them out, yet is the search more pro- fitable than pleasant, both to them that undertake it, and also to the lookers on." Geometry has its half-solved or unsolved and perplex- ing problems, no less than Ethical Science or Religious Faith. It deals with the relations and properties of space. But what is space ? Is it a substance, an accident, or a relation ? Is it fixed and absolute, or relative only ? Is it finite or infinite? Is Infinite Space a real something, or a mere expression for the " imbecility of human thought" ? Can there be empty space, or must there be a plenum? Is it infinitely divisible ? Can there be a surface without depth, a line without breadth, a point without length, breadth, or thickness? Velocity is the speed or rate of motion, or space divided by time. How can this vary from moment to moment, when both the space and the time, for any one rate of motion, wholly vanish and disappear ? These questions, and a host of the same kind, furnish large materials for controversy and metaphysical debate. Had geometers forborne their la- bours till a perfect and clear solution of all these 4 had been found, the science would be still unborn. Pythagoras would never have slain a hecatomb for his immortal dis- covery, the Elements of Euclid never have been written ; the tomb of Archimedes, re-discovered by Cicero with natural triumph, would never have borne the trophies of his skill, the cone, the cylinder, and the sphere. The later triumphs of modern analysis would have been still more impossible. But they laboured on, and built still on the 38 THE CERTAINTY OF MORAL TRUTH. old foundations. They did not pause to grope beneath them in that region of mystery, on which all first prin- ciples must repose. For there our finite reason strives in vain to search out the unsearchable, or to attain that full insight and perfect knowledge, which the Omniscient God, the Only Wise, seems to reserve for Himself alone. The course pursued in moral inquiries has not been altogether the same. There have been repeated attempts, it is true, and never wholly fruitless, to develop the con- sequences of the first principles of Ethics, and unfold them in systematic harmony. Dr Wheweli's Elements are one example of this kind, well worthy of high praise and patient study. But, in general, more pains have been taken in re-examining the grounds of Ethics, or in exploring its debated border lands, than in tilling the soil, and reaping peaceful harvests. Or else systems have been reared on a doubtful basis, maintained by some, and by others stoutly denied. Thus an air of instability has often been given to the whole structure. Systematic Moralists are thus joined at various points in their progress, like troops in full march by stragglers, by many who dispute or deny some of their premises ; and who, in the words of Jeremy Taylor, are " sure of the thing, even when they are by no means sure of the argument." But conclusions, however true and sound, when reached independently of the pre- mises, or even in spite of their rejection, are wanting in all the main features of exact, well denned scientific truth. But a third objection to the claim of Ethics, even more serious and vital than the discords and disputes of moralists, has been drawn from their supposed barren- ness, and entire want of real progress. The contrast between the stationary aspect of moral, and the pro- THE CERTAINTY OF MORAL TRUTH. 39 gressive aspect of intellectual truths, is said to be startling. " All the great moral systems which have exer- cised much influence have been fundamentally the same. All the great intellectual systems have been fundamentally different." These statements of Mr Buckle, on the face of them, are excessive and untrue. The teaching of the Stoics differed widely from that of the Epicureans in ancient times, and both of them diverge widely from the ethics of the gospel. The contrast between Hobbes and Mandeville on the one side, and Cudworth and Clarke on the other, is not less in modern days. On the other hand, close resemblances may be found between some of the latest novelties of modern scepticism, with its pantheism, fatal- ism, and nescience, and the oldest forms of Eastern specu- lation. Still, when all abatements are made, there is a contrast not to be denied, between the rapid progress of Physics in these two last centuries, and the seeming want of growth in the field of ethical inquiry. What answer can be given to this reproach, while claiming for Ethics to be the highest and noblest part of all purely human science ? Now scientific progress may be of four different kinds. These may be styled briefly, ascensive, expansive, de- scensive, and diffusive. A science may climb higher to- wards those simple laws which rule over all its complex phenomena. It may range over a wider landscape, by unfolding these laws into a rich and large variety of secondary axioms. It may stoop down, to apply its dis- coveries more frequently and largely to the uses of daily life. It may gather around it a wider and wider circle of disciples, and may thus spread its light further and further in successive generations. 40 THE CERTAINTY OF MORAL TRUTH. To begin with the last. The diffusion of Ethical Truth has been greater, not less, than that of modern Physics. Its first maxims, indeed, are so simple as to be easily mistaken for truisms, and excite the contempt of those who cultivate the intellect and neglect the heart. They may thus be decried as too commonplace to form the basis of any science worthy of the name. So to eyes accustomed only to gaslights and chandeliers, a fixed star at midnight may seem a worthless thing. It has always been there in the sky for ages, and its light is very small and feeble. And yet this simplicity of moral maxims favours their wide diffusion, and helps to secure their spread throughout the family of mankind. " There is no speech nor language, where their voices are not heard." The great law of truth, the voice which condemns treach- ery and falsehood, appeals to millions who never heard of, much less received, the Copernican and Newtonian theories. The law of kindness and goodwill has vibrated through myriad hearts, which never dreamed of the undulations of light, and to whom spectrum-analysis and polarization are mysteries unheard of and unknown. The law of self- sacrifice for the good of others, whether presented in word only, or embodied in the life and death of martyrs, or enshrined in the deepest mystery of our faith, has touched and stirred the deepest waves of thought in countless hearts, to whom nearly all the terms of modern science are sounds without a meaning. The moral science of the past may perhaps be ele- mentary in the extreme. But even in its weakness, and amidst its ceaseless struggle with prevailing vice and passion, it has exerted a far deeper power over millions of hearts and lives, than Physics have attained in the hour of their noblest triumphs, or can ever hope to attain. THE CERTAINTY OF MORAL TRUTH. 41 Let us next compare Physics with Ethics in their descensive progress, or their practical application to the uses of human life. Natural Philosophy, since the days of Newton, has doubtless enriched society with a great mul- titude of new inventions. It has supplied comforts to the artisan and cottager, as well as multiplied luxuries and triumphs of art for the homes of wealth and the palaces of kings. But this kind of progress is no less real, no less extensive, in Christian Morals than in Physical Science. The virtuous man, the sincere and upright Christian, finds occasion every day and every hour to practise anew, and unfold in some fresh application, the great and simple precepts of Christian morality. The liberal man will continually be devising liberal things. The virtuous woman "opens her lips with wisdom, and in her tongue is the law of kindness." A pure fountain will hourly be sending forth pleasant streams. The quiet, ceaseless ac- tivity of great moral truths, once received into the under- standing and heart of Christian men, may easily be over- looked by busy workers on the ant-hill of science, or else may be forgotten in the glare of some brilliant invention or new discovery. But it is not on that account the less real and important. In the words of Cowper, Stillest streams Oft water fairest meadows, and the bird That flutters least is longest on the wing. I come now to that double progress of science, in as- cent and in expansion, where Physics may seem at first sight to have a real superiority. Even here, I think, the claim will appear groundless on a closer view. "There is nothing in the world," Mr Buckle says, "which has undergone so little change as the great 42 THE CERTAINTY OF MORAL TRUTH. dogmas of which moral systems are composed." On the other hand, those highest laws, which embody the clearest results of modern physical discovery, the law of attraction, the undulations of light, the correlation of force in various forms, have been reached by a slow and painful ascent in the course of ages. When once attained, they work a mighty revolution in our knowledge of the material world, and in our power to control its manifold changes. Is this a proof that Ethics are lower than Physics in the scale of science, and moral truths more uncertain and inferior in practical value ? Far from it. What is cheap and procured without labour is apt indeed to be despised. But even in the natural world, the air, the sunshine and light of heaven, the rains and dews that fertilize the earth, are gifts freely bestowed on men, and require no human labour. If the Divine wisdom has secured to all men, whether by the voice of conscience, or by supernatural revelation, direct access to the vital elements of moral truth, and has left the answering laws or principles of the outward world to reward the study of the philosopher, and to be explored by human toil, ought the free gift, on this account, to be despised, or consigned with contempt to the list of useless and barren truisms ? The law of gravitation is a noble triumph of human sagacity and persevering labour. After long ages of pre- paration, by Ptolemy, Copernicus, and Kepler, the pro- found study of Newton deciphered the handwriting of that Divine law, and expounded it clearly for the admira- tion of mankind. But the great law of duty — " Thou shalt love thy neighbour as thyself," however early or clearly revealed, is higher and nobler still. We may apply to it the verses of Sophocles, not in disparagement, but in praise ; — THE CERTAINTY OF MORAL TRUTH. 43 Ov yap tl vvv re KcLxOes, dXV etet irore Zfi ravra, Kovdels older e£ 6'rou 'r). What, then, is the main feature of that progress of astronomy, during the two last centuries, which is the chief boast of Physical Philosophy, and holds an undis- puted primacy among its many signs of vitality and growing power ? It is the unchanged recognition cf one great law, and increasing faith in its perfect truth, amidst the immense complexity, the mathematical difficulties, and the ever-enlarging variety, of its results and applica- tions. It forms thus a sublime example of permanence amidst ceaseless progress. Other branches of Physics have not reached this goal, and their ultimate laws still elude research. There is change and uncertainty in the first principles themselves. The hypothesis of emission, even though sustained by Newton's authority, retires and gives place to a theory of undulations. This theory, again, in its first form of direct, is replaced by another of transverse vibrations. Caloric, the fictitious fluid of heat, disappears, and atomic motion comes in its stead. The old elements, as ele- ments, pass away. Phlogiston is born, and has an early death. Forty or fifty new elements occupy the fore- ground. But they hold their place by a precarious tenure, till chemistry takes a further stride. The simplest ele- ments, oxygen and hydrogen, now represent in their names the ghost of a departed theory. Magnetic and electric fluids come like shadows, and like shadows they depart. Here science is still only on the steep and slippery moun- tain side. Though it may wield its ice-axe with steady skill, it mounts slowly and with labour. And not seldom it slips backward, when some hasty, seductive hypotheses, like a crevasse thinly covered with new-fallen snow, 44 THE CERTAINTY OF MORAL TRUTH. betrays its insecure foothold. But astronomy, since the days of Newton, seems to stand firm on the mountain-top, and gazes calmly on an ever-widening range of peaceful scientific victories. Now whence arises this manifest superiority over other branches of physical study? The reason is plain. Astronomy has attained a comprehensive simplicity in its primary law, and fountain truth, such as Ethics, with the aid of a Divine message, had attained long ages ago. For what is the second great commandment ? It is a higher law than that of universal gravitation, binding together the whole universe of moral agents. And it has been revealed, more dimly by natural conscience, but in plain and express terms by the great and divine Author of man's moral being. The simplicity and terseness, then, of the first prin- ciples of Morals, is not, as the modern historian falsely con- ceives, their shame and weakness. It forms rather, as the great tragedian of Athens more truly saw, their strength and their glory. The roads and pathways of earth change continually with the revolutions of human society. Mule-tracks are replaced by turnpikes or Roman causeys, and these, in course of time, by iron railroads. But in the blue sky there are no such fashions of the age. The courses of the stars are silent and unchangeable. Moral truths are the stars of the intellectual world. They differ from those lights, useful and yet earthly, which men dig up from the mine, distil in their retorts, conduct through pipes, and transmit to burners, all of them the laborious products of human skill. They shine by their own native light. They look down upon us calmly from above, unless when fogs and mists of earth intercept their brilliance. They are waymarks for the benighted, THE CERTAINTY OF MORAL TRUTH. 45 and also dim heralds of the coming day-break. " Men may- come, and men may go/' — their mines may be exhausted, their pipes burst, their candles flicker and waste away, — but these stars are immortal, and shine on for ever. But has not experience at least proved an immense contrast between moral maxims and the laws of Physics in their power of expansion and development? The first are stationary and barren. Nothing has been added to them, it is said, by the sermons, homilies, and text-books of a thousand moralists and divines. The others are fertile, active, and progressive, and receive from year to year a more full and large development. The contrast, though greatly exaggerated in the remarks to which I refer, has doubtless a partial truth. The development of the great truths of Ethics, in modern times, has been far less apparent to common observers than the growth and progress of Physical Science. A fuller knowledge of the best moralists and divines than physical students, and especially positive philosophers, usually care to attain, will mitigate the sharpness of the alleged contrast, but cannot wholly remove it. When, how- ever, we look below the surface, the seeming defect will be found to have its source, partly in the moral evil which in- terferes with and clogs all ethical study, but partly in the superiority and higher dignity of Moral Science. In Physics the development of theory, and its applica- tion to the practical uses of life, are to a great extent independent of each other. The theory of magnetism might still advance to new discoveries, though timorous navigators were to abandon the use of the compass, and to creep, as in early times, timidly along the shore. Art may grow by happy accidents, and the increase of prac- tical cleverness, while the answering science remains 46 THE CERTAINTY OF MORAL TRUTH. stationary. Science may take immense strides in advance, before its discoveries begin to be applied in new inven- tions, and yield fruit in the service of daily life. In Morals the case is wholly different. Its true aim, as Aristotle observes, is "not that we may know what virtue is, but that we may become good men; for else it would be useless." It is thus essentially a practical science. It teaches men what they ought to be, what they ought to do. Its theory, when wholly divorced from practice, is not only useless, but even mischievous. It aggravates and redoubles guilt. "To him that knoweth to do good, and doeth it not, to him it is sin." Thus in Moral Science theory and practice are not capable, as they are in lower sciences, of a wholly separate development. Corrupt, selfish, vicious practice, must cloud the eye of the soul, and impair or destroy the faculty of moral discernment. Knowledge of the truth cannot grow, unless the truth already known be received into the heart, and applied in the life. In Physics speculation is like an engine with no train attached, which can thus move more freely, and advance at a swifter pace. In Moral Science it is so closely linked with the whole moral being, that the mind, heart, and life, the conscience, intel- lect, and affections, must advance or recede, must rise or fall together. In a world, then, where moral evil plainly abounds, it is no wonder that Ethics, even as a science, should make only a slow, intermittent, and faltering pro- gress. Its standard, raised higher here and there for a moment, must fall again whenever luxury and selfishness abound. Progress made by the calm and patient medita- tions, or the heroic virtues of a few, may be lost, to all out- ward appearance, by the empty folly or fierce and angry passions of the many. The fires of some scorching judg- THE CERTAINTY OF MORAL TRUTH. 47 ment may be needed from time to time, before conscience can burst the chains of reigning sensuality, shake itself from the dust, escape from its cave of shadows, stand erect in the freedom of a new life, and gaze with clear vision and open eye on the grand realities of the spiritual world. There is no reason, then, from the limited progress of Ethical Science in time past, to depreciate its worth, or to doubt its capacity for vast and large expansion in days more favourable to its development. In the sacred words of its Lord and Master, " its hour is not yet come." It has now to struggle onward and upward under the burden of a host of sluggish or perverse disciples, ready to turn aside into seductive by-paths, or to sink lower and lower in vice and folly. These load with a heavy weight, and weaken with a stifling atmosphere of moral impurity, even those willing learners who lend themselves to nobler impulses, and strive to rise. The allegory in Comus well describes, side by side with its real worth and divine effects, the contempt with which it has thus come too often to be regarded by some physical students : The leaf was darkish, and had prickles on it, But in another country, as he said, Bore a bright, golden flower, but not in this soil : Unknown, and like esteemed, and the dull swain Treads on it daily with his clouted shoon; And yet more medicinal is it than that moly Which Hermes once to wise Ulysses gave. In a happier age, assured to us by Divine promise, that bright, golden flower will appear. Or rather, in the sacred words of Scripture, it will become " a tree of life, yielding its fruit every month," and its leaves will be for the heal- ing of the nations. I must reserve for another Lecture the fourth and last hindrance to the claims of Moral Science in the doctrine 48 THE CERTAINTY OF MORAL TRUTH. of probability, and some direct enforcement of the cer- tainty of moral truths. But before I close I must add a few words on the vast importance of a full confidence in their authority, reality, and unchangeableness, to meet and overcome the special dangers of the time in which we live. Amidst the busy activity of commerce, the excitement of political strife and change, the progress of physical inquiry, and all the feverish, impatient movements of modern thought, careful observers must observe one symptom full of danger. Multitudes, in every Christian land, seem to be more and more uncertain on every sub- ject that rises above man's animal wants and desires, and which touches on the unseen and eternal. The Christian Church, the domain of Theology, is vexed with endless controversy and division. Rival bodies of Christians seem often more jealous of each other than zealous for common truth. Political life is in danger of sinking into a mere strife of parties, ranged under doubtful banners, ill de- ciphered and guessed at by their own followers, — a battle without generals and without discipline. One tide-wave of popular impulse follows another in swift succession. All old landmarks are ready to disappear beneath the shifting flood. But where shall certainty be found ? Where can the toil-worn spirit of man find solid footing, and attain a sabbath of rest ? He can never be content to find it in the properties of numbers, in squares, triangles, and poly- gons alone. A secret instinct whispers to him, even when most debased by folly, that his true portion must be sought, and can only be found, in a higher and nobler field. Tell him that morals and religious faith are a Hyperborean region, buried in fog and mist and perpetual darkness, where endless uncertainty reigns, and doubt, THE CERTAINTY OF MORAL TRUTH. 49 sometimes honest, but more frequently dishonest, is the highest attainment, and some slight excess of the chances in its favour the only reason for a virtuous life, and what results will follow ? Such a view will palsy the arm of the Christian, when uplifted for noble action, and strike an icy coldness to his heart. Can we, who inherit the transmitted wealth of thought of so many ages, not from heathen philosophers alone, but from prophets and apostles, and the great lights of the Church of Christ in all past ages, have fallen back, in these last times, into disgraceful contentment with more than heathen darkness ? Are we ready to accept, as the teaching of advanced philosophy, a creed of pure nihilism, that Theology is a dream, religion pare nescience, covered thinly with a crust of decaying dogmas and idle fancies, — conscience a strange function of nervous tissues, or at best the acquired instinct of slaves, who crouch sullenly under the lash of masters stronger or more numerous than themselves ? Then indeed our boasted light can only be paralleled by the state of Elymas the stricken sorcerer, when there fell upon him "mist and darkness," and he groped about for some one to lead him by the hand. Such a view of Moral Science, as a field of mere un- certainties, is gloomy in itself, and disheartening and melancholy in the results to which it must lead. Our duty as Christians, and even as students in this great university, doubly adorned by the greatest lights in Phy- sics and Theology, is to hold firmly a more hopeful and far nobler view. Ethics is the Science of Ideal Humanity. It deals with that lofty standard of the good, the right, the true, the noble, towards which all of us, from the least to the greatest, are bound continually to aspire. And this can B. L. 4 50 THE CERTAINTY OF MORAL TRUTH. be no land of mist and shadow. Even in times of heathen darkness it had a starlight of its own. The Gentiles, who had no direct revelation, were a law unto them- selves. And now, in the times of the Gospel, it has a light as of the daybreak, which shines more and more, in honest and loving hearts, unto the perfect day. Its lowest regions, indeed, must partake largely of the uncertainties and complexities of that human life with which it has to deal, with its manifold conditions of bodily faculties, mental powers, diverse tastes, and different social relations. But above and beyond these there is a higher region, where it rises above the complex and ever varying ap- plications of its own laws, and deals with the inward motives, affections, and desires alone. And here it breathes a purer air, it eats angels' food, and walks in the light of heaven. The firmness of its deep foundations below is only rivalled by the pureness and clearness of the light that shines upon its higher summits from above. To such an Ethical Science, so firmly rooted in essential truth, and rising to such a lofty elevation above the mists and clouds of sceptical uncertainty, which vex and obscure the minds of busy multitudes in this present age, we may apply the description of one who is supposed to have practised its high lessons, and to have taught them to his simple flock, the pastor of the Deserted Village: As some tall cliff that lifts its awful form, Swells from the vale, and midway meets the storm ; Though round its hreast the rolling clouds are spread, Eternal sunshine settles on its head! LECTUEE III. THE CERTAINTY OF MORAL TRUTH. Experience and Reason* The doctrine that in all moral subjects probability is the highest attainment, is a part of the wider theory of the ancient Academy, and has been held by many moral- ists in later times. Aristotle remarks that "it is the duty of one well instructed to seek for accuracy in every kind of subject, only so far as its nature allows;" and that "it is much the same error to be content with mere per- suasion from a mathematician, and to require demonstra- tions from the rhetorician." "Every discourse," he adds further, "about things to be done must be in outline, and not exact." He seems here to contrast geometry with ethics, and to impute inexactness and uncertainty to the latter, but to practical or applied ethics alone. The later Academy held the principle more widely, that in all things probability was the utmost limit of the human mind, from the fallibility of the senses, and the difficulties and seeming contradictions in every field of thought. Bp. Butler, again, is led to insist often on the responsi- bility which results, in moral and religious subjects, from even probable evidence and imperfect half-knowledge. 4—2 52 THE CERTAINTY OF MORAL TRUTH. But this line of thought is often carried so far, as at least to verge on a dangerous extreme. The doubtfulness of the evidence, in such cases, is sometimes assigned to Divine appointment, in order to vary and enlarge the field of moral discipline and probation. The strict discharge of duty, he says, with less sensible evidence, does imply a better character than the same diligence in the discharge of it on more sensible evidence. "And men are bound," he observes, "to act on what appears to them, to the best of their judgment, to be for their happiness, as really as on what they certainly know to be so." It is plain, however, that mere guesses and probabilities, even when they involve a practical duty to act upon the more likely of two alternatives, can never form the materials of a genuine science. "Physical and Moral Studies have a common ground ; science, and not probability, is the aim of both." Such is one of the latest words of Professor Maurice in his Lectures on Social Morality. The principle thus affirmed is one of high importance. It might almost claim to be the foundation of Morals as a Science. I do not think that it is to be viewed as the consequence and result of worship. It is rather the indispensable condition that worship may be a reasonable service, and not sink into a blind superstition. It is a conviction by no means limited to those writers who lean to a mystic or transcendental school of thought. The judgment of Locke in its favour has double force; since it might have seemed natural for him, from the general tone of his famous treatise, to rest content with a lower view. He writes as follows ; — " The ideas of quantity are not those which alone are capable of demonstration and knowledge. Other, and perhaps more useful parts of contemplation would afford THE CERTAINTY OF MORAL TRUTH. 53 us certainty, if vices, passions, and domineering interests did not oppose or menace the endeavour." "The idea of a Supreme Being, infinite in power, wisdom, and goodness, whose workmanship we are, and on whom we depend ; and the idea of ourselves, as under- standing, rational beings, being such as are clear in us, would, if duly considered, afford such foundations of our duty, and rules of action, as might place Morality among the sciences capable of demonstration. I doubt not but, from self-evident propositions, by necessary consequences, .as incontestable as those of Mathematics, the measures of right and wrong might be made out, to any one that will apply himself with the same attention and indifferency to the one, as he does to the other, of these sciences." u Two things," he continues, " have made moral ideas thought incapable of demonstration, their complexness, and their want of sensible representation."
