And here I may observe that the term inductive, like most others that are employed in moral philosophy, may give rise to serious misconception. It is properly applied to those moralists who, disbelieving the existence of any moral sense or faculty revealing to us what is right and wrong, maintain that the origin of those ideas is simply our experience of the tendency of different lines of conduct to promote or impair true happiness. It appears, however, to be sometimes imagined that inductive moralists alone think that it is by induction or experience that we ought to ascertain what is the origin of our moral ideas. But this I conceive to be a complete mistake. The basis of morals is a distinct question from the basis of theories of morals. Those who maintain the existence of a moral faculty do not, as is sometimes said, assume this proposition as a first principle of their arguments, but they arrive at it by a process of induction quite as severe as any that can be employed by their opponents.99 They examine, analyse, and classify their existing moral feelings, ascertain in what respects those feelings agree with or differ from others, trace them through their various phases, and only assign them to a special faculty when they think they have shown them to be incapable of resolution, and generically different from all others.100
This separation is all that is meant by a moral faculty. We are apt to regard the term as implying a distinct and well defined organ, bearing to the mind the same kind of relation as a limb to the body. But of the existence of such organs, and of the propriety of such material imagery, we know nothing. Perceiving in ourselves a will, and a crowd of intellectual and emotional phenomena that seem wholly different from the properties of matter, we infer the existence of an immaterial substance which wills, thinks, and feels, and can classify its own operations with considerable precision. The term faculty is simply an expression of classification. If we say that the moral faculty differs from the æsthetic faculty, we can only mean that the mind forms certain judgments of moral excellence, and also certain judgments of beauty, and that these two mental processes are clearly distinct. To ask to what part of our nature moral perceptions should be attributed, is only to ask to what train of mental phenomena they bear the closest resemblance.
If this simple, but often neglected, consideration be borne in mind, the apparent discordance of intuitive moralists will appear less profound than might at first sight be supposed, for each section merely elucidates some one characteristic of moral judgments. Thus Butler insists upon the sense of obligation that is involved in them, contends that this separates them from all other sentiments, and assigns them in consequence to a special faculty of supreme authority called conscience. Adam Smith and many other writers were especially struck by their sympathetic character. We are naturally attracted by humanity, and repelled by cruelty, and this instinctive, unreasoning sentiment constitutes, according to these moralists, the difference between right and wrong. Cudworth, however, the English precursor of Kant, had already anticipated, and later metaphysicians have more fully exhibited, the inadequacy of such an analysis. Justice, humanity, veracity, and kindred virtues not merely have the power of attracting us, we have also an intellectual perception that they are essentially and immutably good, that their nature does not depend upon, and is not relative to, our constitutions; that it is impossible and inconceivable they should ever be vices, and their opposites, virtues. They are, therefore, it is said, intuitions of the reason. Clarke, developing the same rational school, and following in the steps of those moralists who regard our nature as a hierarchy of powers or faculties, with different degrees of dignity, and an appropriate order of supremacy and subordination, maintained that virtue consisted in harmony with the nature of things. Wollaston endeavoured to reduce it to truth, and Hutcheson to benevolence, which he maintained is recognised and approved by what his respect for the philosophy of Locke induced him to call “a moral sense,” but what Shaftesbury had regarded as a moral “taste.” The pleasure attending the gratification of this taste, according to Shaftesbury and Henry More, is the motive to virtue. The doctrine of a moral sense or faculty was the basis of the ethics of Reid. Hume maintained that the peculiar quality of virtue is its utility, but that our affections are purely disinterested, and that we arrive at our knowledge of what is virtuous by a moral sense implanted in our nature, which leads us instinctively to approve of all acts that are beneficial to others. Expanding a pregnant hint which had been thrown out by Butler, he laid the foundation for a union of the schools of Clarke and Shaftesbury, by urging that our moral decisions are not simple, but complex, containing both a judgment of the reason, and an emotion of the heart. This fact has been elucidated still further by later writers, who have observed that these two elements apply in varying degrees to different kinds of virtue. According to Lord Kames, our intellectual perception of right and wrong applies most strictly to virtues like justice or veracity, which are of what is called “perfect obligation,” or, in other words, are of such a nature, that their violation is a distinct crime, while the emotion of attraction or affection is shown most strongly towards virtues of imperfect obligation, like benevolence or charity. Like Hutcheson and Shaftesbury, Lord Kames notices the analogies between our moral and æsthetical judgments.
These last analogies open out a region of thought widely different from that we have been traversing. The close connection between the good and the beautiful has been always felt, so much so, that both were in Greek expressed by the same word, and in the philosophy of Plato, moral beauty was regarded as the archetype of which all visible beauty is only the shadow or the image. We all feel that there is a strict propriety in the term moral beauty. We feel that there are different forms of beauty which have a natural correspondence to different moral qualities, and much of the charm of poetry and eloquence rests upon this harmony. We feel that we have a direct, immediate, intuitive perception that some objects, such as the sky above us, are beautiful, that this perception of beauty is totally different, and could not possibly be derived, from a perception of their utility, and that it bears a very striking resemblance to the instantaneous and unreasoning admiration elicited by a generous or heroic action. We perceive too, if we examine with care the operations of our own mind, that an æsthetical judgment includes an intuition or intellectual perception, and an emotion of attraction or admiration, very similar to those which compose a moral judgment. The very idea of beauty again implies that it should be admired, as the idea of happiness implies that it should be desired, and the idea of duty that it should be performed. There is also a striking correspondence between the degree and kind of uniformity we can in each case discover. That there is a difference between right and wrong, and between beauty and ugliness, are both propositions which are universally felt. That right is better than wrong, and beauty than ugliness, are equally unquestioned. When we go further, and attempt to define the nature of these qualities, we are met indeed by great diversities of detail, but by a far larger amount of substantial unity. Poems like the Iliad or the Psalms, springing in the most dissimilar quarters, have commanded the admiration of men, through all the changes of some 3,000 years. The charm of music, the harmony of the female countenance, the majesty of the starry sky, of the ocean or of the mountain, the gentler beauties of the murmuring stream or of the twilight shades, were felt, as they are felt now, when the imagination of the infant world first embodied itself in written words. And in the same way types of heroism, and of virtue, descending from the remotest ages, command the admiration of mankind. We can sympathise
