Abstract

Although it goes against a widespread significant misunderstanding of his view, Michael Smith is one of the very few moral philosophers who explicitly wants to allow for the commonsense claim that, while morally required action is always favored by some reason, selfish and immoral action can also be rationally permissible. One point of this paper is to make it clear that this is indeed Smith's view. It is a further point to show that his way of accommodating this claim is inconsistent with his wellknown "practicality requirement" on moral judgments: the thesis that any rational person will always have at least some motivation to do what she judges to be right. The general conclusion is that no view that, like Smith's, associates the normative strength of a reason with the motivational strength of an ideal desire will allow for the wide range of rational permissibility that Smith wants to capture.
