Abstract

Many of us have a prereflective sense--or at least, a hope--that there are reasons to be moral which apply to an agent regardless of what his or her existing motivations may be. The view that there are no such reasons may, then, be regarded as a form of moral scepticism. The philosophical position which seems most fit to refute this form of moral scepticism, and hence to support our prereflective sense, is a Kantian view of morality, according to which we are required to be moral solely in virtue of being rational. I examine a number of recent arguments for this position; I conclude that all of them fail, and for similar reasons. Nor, I argue, is there any non-Kantian view which could succeed at the same task. It is thus very tempting to infer that this form of moral scepticism is immune to any simple refutation. However, perhaps the best way to combat scepticism is not to argue for its negation--as do the positions examined so far--but to show that there is something problematic in the sceptic's whole approach to the issue. At this point I turn for enlightenment to an analogy with epistemological scepticism. Here, too, if we try to argue for the negation of scepticism, we seem bound to fail; but here the more subtle strategy of attacking the sceptic's whole approach has actually been attempted. I sketch a number of versions of this more subtle strategy; I then sketch some analogous responses to moral scepticism, and consider whether any of them are successful. I argue that the attempt fails--that even if epistemological scepticism is indeed amenable to this kind of treatment , moral scepticism is not. This conclusion is only strengthened when I argue that another, related strategy, which employs an analogy between morality and mathematics, also falls short at the same point. Moral scepticism therefore survives intact. The appropriate reaction, I suggest, is neither complete despair nor complete equanimity
