The psychological question is for most disputants the only question. When your ordinary doctor of {186} 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 {187} 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.
