the assertion that such and such a thing is a duty, or has intrinsic value, ever _a dictate of reason?_ But so far as I can gather, the question really at issue, and expressed in these obscure ways, is the one which I have tried to state. It is the question whether when we judge (whether truly or falsely) that an action is a duty or a state of things good, _all_ that we are thinking about the action or the state of things in question, is simply and solely that we ourselves or others have or tend to have a certain feeling towards it when we contemplate or think of it. And the question seems to me to be of great interest, because, if this is all, then it is evident that all the ideas with which Moral Philosophy is concerned are merely psychological ideas; and all moral rules, and statements as to what is intrinsically valuable, merely true or false psychological statements; so that the whole of Moral Philosophy and Ethics will be merely departments of Psychology. Whereas, if the contrary is the case, then these two ideas of moral obligation and intrinsic value, will be no more purely psychological ideas than are the ideas of shape or size or number; and Moral Philosophy will be concerned with characteristics of actions and feelings and states of affairs, which these actions and feelings and states of affairs would or might have possessed, even if human psychology had been quite different from what it is. Which, then, of these two views is the true one? Are these two ideas merely psychological ideas in the sense which I have tried to explain, or are they not?
