2. The connection between Ethics and Aesthetics is closer. Aesthetics is the science of the laws of beauty, while Ethics is the science of the laws of the good. But in so far as Aesthetics deals with the emotions rather than the reason it comes into contact with Ethics in the psychological field. In its narrower sense Aesthetics deals with beauty merely in an impersonal way; and its immediate object is not what is morally beautiful, but rather that which is beautiful in itself irrespective of moral considerations. Ethics, on the other hand, is concerned with personal worth as expressed in perfection of will and action. Conduct may be beautiful and character may afford Aesthetic satisfaction, but Ethics, in so far as it is concerned with judgments of virtue, is independent of all thought of the mere beauty or utility of conduct. Aesthetic consideration may indeed aid practical morality, but it is not identical with it. It is conceivable that what is right may not be immediately beautiful, and may indeed in its pursuit or realisation involve action which contradicts our ideas of beauty. But though both sciences have different aims they are occupied largely with the same emotions, and are connected by a common idealising purpose. In the deepest sense, what is good is beautiful and what is beautiful is good; and {16} ultimately, in the moral and spiritual life, goodness and beauty coincide. Indeed, so close is the connection between the two conceptions that the Greeks used the same word, to kalon, to express beauty of form and nobility of character. And even in modern times the expression 'a beautiful soul,' indicates the intimate relation between inner excellence of life and outward attractiveness. Both Aesthetics and Ethics have regard to that symmetry or proportion of life which fulfils our ideas at once of goodness and of beauty. In this sense Schiller sought to remove the sharpness of Kant's moral theory by claiming a place in the moral life for beauty. Our actions are, indeed, good when we do our duty because we ought, but they are beautiful when we do it because we cannot do otherwise, because they have become our second nature. The purpose of all culture, says Schiller, is to harmonise reason and sense, and thus to fulfil the idea of a perfect manhood.[5]
'When I dared question: "It is beautiful,
But is it true?" Thy answer was, "In truth lives beauty."'[6]
3. Politics is still more closely related to Ethics, and indeed Ethics may be said to comprehend Politics. Both deal with human action and institution, and cover largely the same field. For man is not merely an individual, but is a part of a social organism. We cannot consider the virtues of the individual life without also considering the society to which he is related, and the interaction of the whole and its part. Politics is usually defined as the science of government, which of course, involves all the institutions and laws affecting men's relations to each other. But while Politics is strictly concerned only with the outward condition of the state's well-being and the external order of {17} the community, Ethics seeks the internal good or virtue of mankind, and is occupied with an ideal society in which each individual shall be able to realise the true aim and meaning of life. But after all, as Aristotle said, Politics is really a branch of Ethics, and both are inseparable from, and complementary of each other. On the one hand, Ethics cannot ignore the material conditions of human welfare nor minimise the economic forces which shape society and make possible the moral aims of man. On the other hand, Economics must recognise the service of ethical study, and keep in view the moral purposes of life, otherwise it is apt to limit its consideration to merely selfish and material ends.
V. While Ethics is thus closely connected with the sciences just named, there are two departments of knowledge, pre-supposed indeed in all mental studies, which in a very intimate way affect the science of Ethics. These are Metaphysics on the one hand and Psychology on the other.
1. Metaphysics is pre-supposed by all the sciences; and indeed, all our views of life, even our simplest experiences, involve metaphysical assumptions. It has been well said that the attempt to construct an ethical theory without a metaphysical basis issues not in a moral science without assumptions, but in an Ethics which becomes confused in philosophical doubts. Leslie Stephen proposes to ignore Metaphysics, and remarks that he is content 'to build upon the solid earth.' But, as has been pertinently asked, 'How does he know that the earth is solid on which he builds?' This is a question of Metaphysics.[7] The claim is frequently made by a certain class of writers, that we withdraw ourselves from all metaphysical sophistries, and betake ourselves to the guidance of commonsense. But what is this commonsense of which the ordinary man vaunts himself? It is in reality a number of vague assumptions borrowed unconsciously from old exploded theories—assertions, opinions, beliefs, accumulated, no one knows how, {18} and accepted as settled judgments.[8] We do not escape philosophy by refusing to think. Some kind of theory of life is implied in such words, 'soul,' 'duty,' 'freedom,' 'power,' 'God,' which the unreflecting mind is daily using. It is useless to say we can dispense with philosophy, for that is simply to content ourselves with bad philosophy. 'To ignore the progress and development in the history of Philosophy,' says T. H. Green,[9] 'is not to return to the simplicity of a pre-philosophic age, but to condemn ourselves to grope in the maze of cultivated opinion, itself the confused result of these past systems of thought which we will not trouble ourselves to think out.' The aim of all philosophy, as Plato said, is just to correct the assumptions of the ordinary mind, and to grasp in their unity and cohesion the ultimate principles which the mind feels must be at the root of all reality. We have an ethical interest in determining whether there be any moral reality beneath the appearances of the world. Ethical questions, therefore, run back into Metaphysics. If we take Metaphysics in its widest sense as involving the idea of some ultimate end, to the realisation of which the whole process of the world as known to us is somehow a means, we may easily see that metaphysical inquiry, though distinct from ethical, is its necessary pre-supposition. The Being or Purpose of God, the great first cause, the world as fashioned, ordered and interpenetrated by Him, and man as conditioned by and dependent upon the Deity—are postulates of the moral life and must be accepted as a basis of all ethical study. The distinction between Ethics and Philosophy did not arise at once. In early Greek speculation, almost to the time of Aristotle, Metaphysics and Morals were not separated. And even in later times, Spinoza and to some extent Green, though they professedly treat of Ethics, hardly dissociate metaphysical from ethical considerations. Nor is that to be wondered at when men are dealing with the first principles of all being and life. Our view of God and of the {19} world, our fundamental Welt-Anschauung cannot but determine our view of man and his moral life. In every philosophical system from Plato to Hegel, in which the universe is regarded as having a rational meaning and ultimate end, the good of human beings is conceived as identical with, or at least as included in the universal good.
2. But if a sound metaphysical basis be a necessary requisite for the adequate consideration of Ethics, Psychology as the science of the human soul is so vitally connected with Ethics, that the two studies may almost be treated as branches of one subject. An Ethic which takes no account of psychological assumptions would be impossible. Consciously or unconsciously every treatment of moral subjects is permeated by the view of the soul or personality of man which the writer has adopted, and his meaning of conduct will be largely determined by the theory of human freedom and responsibility with which he starts. Questions as to character and duty invariably lead to inquiries as to certain states of the agent's mind, as to the functions and possibilities of his natural capacities and powers. We cannot pronounce an action morally good or bad until we have determined the extent and limits of his faculties and have investigated the questions of disposition and purpose, of intention and motive, which lie at the root of all conduct, and without which actions are neither moral nor immoral. It is surely a mistake to say, as some do, that as logic deals with the correctness of reasoning, so Ethics deals only with the correctness of conduct, and is not directly concerned with the processes by which we come to act correctly.[10] On the contrary, merely correct action may be ethically worthless, and conduct obtains its moral value from the motives or intentions which actuate and determine it. Ethics cannot, therefore, ignore the psychological processes of feeling, desiring and willing of the acting subject. It is indeed true that in ordinary life men are frequently judged to be good or bad, according to the outward effect of their actions, and material results are often regarded as the sole {20} measure of good. But while it may be a point of difficulty in theoretic morality to determine the comparative worth and mutual relation of good affections and good actions, all surely will allow that a certain quality of disposition or motive in the agent is required to constitute an action morally good, and that it is not enough to measure virtue by its utility or its beneficial effect alone. Hence all moralists are agreed that the main object of their investigation must belong to the psychical side of human life—whether they hold that man's ultimate end is to be found in the sphere of pleasure or maintain that his well-being lies in the realisation of virtue for its own sake. The problems as to the origin and adequacy of conscience, as to the meaning and validity of voluntary action; the questions concerning motives and desires, as to the historical evolution of moral customs, and man's relation at each stage of his history to the social, political and religious institutions amid which he lives—are subjects which, though falling within the scope of Ethics, have their roots in the science of the soul. The very existence of a science of Ethics depends upon the answers which Psychology gives to such questions. If, for example, it be decided that there is in man no such faculty or organ as conscience, and that what men so designate is but a natural manifestation gradually evolved in and through the physical and social development of man: or if we deny the self-determining power of human beings and assume that what we call the freedom of the will is a delusion (or at least, in the last resort, a negligible element) and that man is but one of the many phenomena or facts of a physical universe—then we may continue, indeed, as some evolutionary and naturalistic thinkers do, to speak of a science of Ethics, but such a science will not be a study of the moral life as we understand it and have defined it.
Ethics, therefore, while dependent upon the philosophical sciences, has its own distinct content and scope. The end of life, that for which a man should live, with all its implications, forms the subject of moral inquiry. It is {21} concerned not merely with what a man is or actually does, but more specifically with what he should be and should do. Hence, as we have seen, the word 'ought' is the most distinctive term of Ethics involving a consideration of values and a relation of the actual and the ideal. The 'ought' of life constitutes at once the purpose, law, and reason of conduct. It proposes the three great questions involved in all ethical inquiry—whither? how? and why? and determines the three great words which are constantly recurring in every ethical system—end, norm, motive. Moral good is the moral end considered as realised. The moral norm or rule impelling the will to the realisation of this end is called Duty. The moral motive considered as an acquired power of the acting will is called Virtue.[11]
