 So when one senses an obligation one senses a character of oneself, a claim on oneself to act in a certain way. And to sense an obligation all that is needed is to put oneself into the relevant situation and consider the various ways of acting that are available, and the various relevant relations in which one stands to others and to oneself. If this does not lead to a sense of obligation, there is nothing much else that can do it. Moral philosophy, certainly, offers no such resources, and the Mistake on which Moral Philosophy rests, to revert to the title of Prichard’s famous article, is to suppose otherwise.
