they are necessarily worthless because unstable in their premises. "If," say the objectors, "this 'moral sense,' to which all these writers directly or indirectly appeal, possesses no fixity, gives no uniform response, says one thing in Europe, and another in Asia-originates different notions of duty in each age, each race, each individual, how can it afford a safe foundation for a systematic morality? What can be more absurd than to seek a definite rule of right, in the answers of so uncertain an authority?" Even granting that there is no escape from this difficulty-even supposing no method to exist, by which from this source, a moral philosophy can be drawn free from so fatal an imperfection, there still results merely that same dilemma, in which every other proposed scheme is involved. If such a guide is unfit, because its dictates are variable, then must Expediency also be rejected for the same reason. If Bentham is right in condemning Moral Sense, as an "anarchical and capricious principle, founded solely upon internal and peculiar feelings," then is his own maxim doubly fallacious. Is not the idea, "greatest happiness," a capricious one? Is not that also "founded solely upon internal and peculiar feelings?" (See page 13.) And even were the idea "greatest happiness" alike in all, would not his principle be still " anarchical," in virtue of the infinite disagreement as to the means of realizing this "greatest happiness?" All utilitarian philosophies are in fact liable to this charge of indefiniteness, for there ever recurs the same unsettled question-what is utility? -a question which, as every newspaper shows us, gives rise to endless disputes, both as to the goodness of each desired end, and the efficiency of every proposed means. At the worst, therefore, in so far as want of scientific precision is concerned, a philosophy founded on Moral Sense, simply stands in the same category with all other known systems. FUNCTION OF THE MORAL SENSE. 41 § 7. But happily there is an alternative. The force of the objection above set forth may be fully admitted, without in any degree invalidating the theory. Notwithstanding appearances to the contrary, it is still possible to construct upon this basis, a purely synthetic morality proof against all such criticism. The error pointed out is not one of doctrine, but of application. Those who committed it did not start from a wrong principle, but rather missed the right way from that principle to the sought-for conclusions. It was not in the oracle to which they appealed, but in their method of interpretation, that the writers of the Shaftesbury school erred. Confounding the functions of feeling and reason, they required a sentiment to do that, which should have been left to the intellect. They were right in believing that there exists some governing instinct generating in us an approval of certain actions we call good, and a repugnance to certain others we call bad. But they were not right in assuming such instinct to be capable of in. tuitively solving every ethical problem submitted to it. To suppose this, was to suppose that moral sense could supply the place of logic. For the better explanation of this point, let us take an analogy from mathematics, or rather some branch of it, as geometry. The human mind possesses a faculty that takes cognizance of measurable quantity, which faculty, to carry out the analogy, let us term a geometric sense. By the help of this we estimate the linear dimensions, surfaces, and bulks of surrounding objects, and form ideas of their relationship to each other. But in the endeavour to reduce the knowledge thus obtained to a scientific form, we find that no reliance can be placed on the unaided decisnons of this geometric sense, in consequence of the conflicting judgments it makes in different persons. On comparing notes, however, we discover that there are certain simple propositions upon which we all think alike, such as "Things which are equal to the same thing are equa to one another; ""The whole is greater than its part; and agreeing upon these axioms as we call them-these fundamental truths recognized by our geometric sense, we find it becomes possible by successive deductions to settle all disputed points, and to solve with certainty, problems of the most complicated nature.* Now if, instead of adopting this method, geometricians had persisted in determining all questions concerning lines, angles, squares, circles, and the like, by the geometric sense-if they had tried to discover whether the three angles of a triangle were, or were not, equal to two right angles, and whether the areas of similar polygons were, or were not, in the duplicate ratio of their homologous sides, by an effort of simple perception, they would have made just the same mistake that moralists make, who try to solve all the problems of morality by the moral sense. The reader will at once perceive the conclusion toward which this analogy points; namely, that the perception of the primary laws of quantity bears the same relationship to mathematics, that this instinct of right bears to a moral system; and that as it is the office of the geometric sense to originate a geometric axiom, from which reason may deduce a scientific geometry, so it is the office of the moral sense to originate a moral axiom, from which reason may develop a systematic morality. And, varying the illustration, it may be further remarked, that just as erroneous notions in mechanicsfor instance, that large bodies fall faster than small * Whether we adopt the views of Locke or of Kant as to the ultimate nature of what is here, for analogy's sake, called geometric sense, does not affect the question. However originated, the fundamental perceptions attaching to it form the undecomposable basis of exact science. And this is all that is now assumed. GROUNDS OF A SCIENTIFIC MORALITY. 43 ones; * that water rises in a pump by suction; that perpetual motion is possible, together with the many other mistaken opinions, formed by unaided mechanical sense-are set aside by the conclusions synthetically deduced from those primary laws of matter which the mechanical sense recognizes; so may we expect the multitudes of conflicting beliefs about human duty dictated by unaided moral sense, to disappear before the deductions scientifically drawn from some primary law of man which the moral sense recognizes. § 8. On reviewing the claims of the Moral Sense doctrine, it appears that there is à priori reason for expecting the first principle of social morality to originate in some feeling, power, or faculty of the individual. Quite in harmony with this belief, is the inference that as desire is found to be the incentive to action where motives are readily analyzable, it is probably the universal incentive; and that the conduct we call moral is determined by it as well as other conduct. Moreover we find that even the great maxim of the expediency-philosophy presupposes some tendency in man toward right relationship with his fellow, and some correlative perception of what that right relationship consists in. There are sundry phenomena of social life, both past and present, that well illustrate the influence of this supposed moral sense, and which are not readily explicable upon any other hypothesis. Assuming the existence of such a faculty, there appears reason to think that its monitions afford a proper basis for a systematic morality; and to the demurrer that their variability unfits them for this purpose, it is replied that, to say the least, the foundations of all other systems are equally open to the same objection. Finally, however, we discover that this difficulty is apparent only, and not real: for that whilst the decisions of this moral sense upon the complex cases referred to it are inaccurate and often contradictory, it may still be capable of generating a true fundamental intuition, which can be logically unfolded into a scientific morality. * A doctrine held by Aristotle and his followers. LEMMA I. § 1. It seems at first sight a very rational way of testing any proposed rule of conduct to ask, How will it work? Taking men as we know them, and institutions as they are, what will result from carrying such a theory into practice? This very common-sense style of inquiry is that by which most opinions on morals and politics are formed. People consider of any system, whether it seems feasible, whether it will square with this or the other social arrangement, whether it fits what they see of human nature. They have got certain notions of what man is, and what society must be; and their verdict on any ethical doctrine depends upon its accordance or discordance with these. Such a mode of settling moral questions, is clearly open to all the criticisms so fatal to the expediency-philosophy. Incapacity for guiding ourselves in detail by making estimates of consequences, implies incapacity for judging of first principles by that method. But passing over this, there is yet another reason for rejecting an inquiry so pursued as worthless; namely, that it assumes the character of mankind to be constant. If moral systems are adopted or condemned, because of their consistency or inconsistency, with what we know of men and things, then it is taken for granted that men and things will ever be as they are. It would be absurd to measure with a variable |
