There are three questions in ethics which must be kept apart. Let them be called respectively the psychological question, the metaphysical question, and the casuistic question. The psychological question asks after the historical origin of our moral ideas and judgments; the metaphysical question asks what the very meaning of the words 'good,' 'ill,' and 'obligation' are; the casuistic question asks what is the measure of the various goods and ills which men recognize, so that the philosopher may settle the true order of human obligations.
I.
The psychological question is for most disputants the only question. When your ordinary doctor of divinity has proved to his own satisfaction that an altogether unique faculty called 'conscience' must be postulated to tell us what is right and what is wrong; or when your popular-science enthusiast has proclaimed that 'apriorism' is an exploded superstition, and that our moral judgments have gradually resulted from the teaching of the environment, each of these persons thinks that ethics is settled and nothing more is to be said. The familiar pair of names, Intuitionist and Evolutionist, so commonly used now to connote all possible differences in ethical opinion, really refer to the psychological question alone. The discussion of this question hinges so much upon particular details that it is impossible to enter upon it at all within the limits of this paper. I will therefore only express dogmatically my own belief, which is this,—that the Benthams, the Mills, and the Barns have done a lasting service in taking so many of our human ideals and showing how they must have arisen from the association with acts of simple bodily pleasures and reliefs from pain. Association with many remote pleasures will unquestionably make a thing significant of goodness in our minds; and the more vaguely the goodness is conceived of, the more mysterious will its source appear to be. But it is surely impossible to explain all our sentiments and preferences in this simple way. The more minutely psychology studies human nature, the more clearly it finds there traces of secondary affections, relating the impressions of the environment with one another and with our impulses in quite different ways from those mere associations of coexistence and succession which are practically all that pure empiricism can admit. Take the love of drunkenness; take bashfulness, the terror of high places, the tendency to sea-sickness, to faint at the sight of blood, the susceptibility to musical sounds; take the emotion of the comical, the passion for poetry, for mathematics, or for metaphysics,—no one of these things can be wholly explained by either association or utility. They go with other things that can be so explained, no doubt; and some of them are prophetic of future utilities, since there is nothing in us for which some use may not be found. But their origin is in incidental complications to our cerebral structure, a structure whose original features arose with no reference to the perception of such discords and harmonies as these.
Well, a vast number of our moral perceptions also are certainly of this secondary and brain-born kind. They deal with directly felt fitnesses between things, and often fly in the teeth of all the prepossessions of habit and presumptions of utility. The moment you get beyond the coarser and more commonplace moral maxims, the Decalogues and Poor Richard's Almanacs, you fall into schemes and positions which to the eye of common-sense are fantastic and overstrained. The sense for abstract justice which some persons have is as excentric a variation, from the natural-history point of view, as is the passion for music or for the higher philosophical consistencies which consumes the soul of others. The feeling of the inward dignity of certain spiritual attitudes, as peace, serenity, simplicity, veracity; and of the essential vulgarity of others, as querulousness, anxiety, egoistic fussiness, etc.,—are quite inexplicable except by an innate preference of the more ideal attitude for its own pure sake. The nobler thing tastes better, and that is all that we can say. 'Experience' of consequences may truly teach us what things are wicked, but what have consequences to do with what is mean and vulgar? If a man has shot his wife's paramour, by reason of what subtile repugnancy in things is it that we are so disgusted when we hear that the wife and the husband have made it up and are living comfortably together again? Or if the hypothesis were offered us of a world in which Messrs. Fourier's and Bellamy's and Morris's Utopias should all be outdone, and millions kept permanently happy on the one simple condition that a certain lost soul on the far-off edge of things should lead a life of lonely torture, what except a specifical and independent sort of emotion can it be which would make us immediately feel, even though an impulse arose within us to clutch at the happiness so offered, how hideous a thing would be its enjoyment when deliberately accepted as the fruit of such a bargain? To what, once more, but subtile brain-born feelings of discord can be due all these recent protests against the entire race-tradition of retributive justice?—I refer to Tolstoi with his ideas of non-resistance, to Mr. Bellamy with his substitution of oblivion for repentance (in his novel of Dr. Heidenhain's Process), to M. Guyau with his radical condemnation of the punitive ideal. All these subtileties of the moral sensibility go as much beyond what can be ciphered out from the 'laws of association' as the delicacies of sentiment possible between a pair of young lovers go beyond such precepts of the 'etiquette to be observed during engagement' as are printed in manuals of social form.
No! Purely inward forces are certainly at work here. All the higher, more penetrating ideals are revolutionary. They present themselves far less in the guise of effects of past experience than in that of probable causes of future experience, factors to which the environment and the lessons it has so far taught as must learn to bend.
This is all I can say of the psychological question now. In the last chapter of a recent work[[2]] I have sought to prove in a general way the existence, in our thought, of relations which do not merely repeat the couplings of experience. Our ideals have certainly many sources. They are not all explicable as signifying corporeal pleasures to be gained, and pains to be escaped. And for having so constantly perceived this psychological fact, we must applaud the intuitionist school. Whether or not such applause must be extended to that school's other characteristics will appear as we take up the following questions.
The next one in order is the metaphysical question, of what we mean by the words 'obligation,' 'good,' and 'ill.'
II.
First of all, it appears that such words can have no application or relevancy in a world in which no sentient life exists. Imagine an absolutely material world, containing only physical and chemical facts, and existing from eternity without a God, without even an interested spectator: would there be any sense in saying of that world that one of its states is better than another? Or if there were two such worlds possible, would there be any rhyme or reason in calling one good and the other bad,—good or bad positively, I mean, and apart from the fact that one might relate itself better than the other to the philosopher's private interests? But we must leave these private interests out of the account, for the philosopher is a mental fact, and we are asking whether goods and evils and obligations exist in physical facts per se. Surely there is no status for good and evil to exist in, in a purely insentient world. How can one physical fact, considered simply as a physical fact, be 'better' than another? Betterness is not a physical relation. In its mere material capacity, a thing can no more be good or bad than it can be pleasant or painful. Good for what? Good for the production of another physical fact, do you say? But what in a purely physical universe demands the production of that other fact? Physical facts simply are or are not; and neither when present or absent, can they be supposed to make demands. If they do, they can only do so by having desires; and then they have ceased to be purely physical facts, and have become facts of conscious sensibility. Goodness, badness, and obligation must be realised somewhere in order really to exist; and the first step in ethical philosophy is to see that no merely inorganic 'nature of things' can realize them. Neither moral relations nor the moral law can swing in vacuo. Their only habitat can be a mind which feels them; and no world composed of merely physical facts can possibly be a world to which ethical propositions apply.
The moment one sentient being, however, is made a part of the universe, there is a chance for goods and evils really to exist. Moral relations now have their status, in that being's consciousness. So far as he feels anything to be good, he makes it good. It is good, for him; and being good for him, is absolutely good, for he is the sole creator of values in that universe, and outside of his opinion things have no moral character at all.
