Innocence and Experience
It is not surprising that exasperated laymen should wonder about the point of moral philosophy; the self-confident often can’t see why intellectuals should struggle to reach conclusions that any decent citizen learned in childhood, while the unconfident may not care for the corrosive effects of all inquiry. It’s rather more surprising that philosophers themselves have often doubted whether moral philosophy was a branch of philosophy at all. Whatever Hume meant when he observed that “reason is and always must be the slave of the passions,” it certainly sounded deflationary, a reminder that moral judgment was less well-founded than our views about mathematics or natural science.

Its impact was an emotional one, and derived from Moore’s scrupulous description of his unargued intuitions of what was, as a matter of fact, good—friendship and beauty. None of this is reassuring. If philosophy is supposed to provide us with good reasons for our beliefs, it is disappointing to learn that in this most important area, it has so little to tell us.

Bernard Williams’s Ethics and the Limits of Philosophy denies that relativism makes any sense when applied to scientific reasoning. Nonetheless, Williams also doubts that a particular set of moral principles could be shown to be literally the “dictates of reason.” Instead of calling on his readers to subscribe to Thomism with Alasdair MacIntyre, or to settle for the virtues of liberal capitalism with Richard Rorty, Williams calls for a …
