Ralph Wedgwood’s The Nature of Normativity significantly advances our understanding of metaethical realism. After briefly reviewing the overall structure of Wedgwood’s argument for a Platonist realism about normativity, this critical notice focuses on three of the central metaphysical and epistemological claims that he defends. I first explain and raise difficulties for Wedgwood’s core claim that the intentional is normative. I then argue that his innovative attempt to finesse the supervenience problem that faces metaethical Platonists fails. Finally, I critically examine his (...) attempt to explain how his Platonism is compatible with an acceptable epistemology of the normative. (shrink)

It is a truism that we ought to be rational. Despite this, it has become popular to think that it is not the case that we ought to be rational. In this paper I argue for a view about rationality—the view that what one is rationally required to do is determined by the normative reasons one possesses—by showing that it can vindicate that one ought to be rational. I do this by showing that it is independently very plausible that what (...) one ought to do is determined by the normative reasons one possesses. Thus, the paper also makes a contribution tos the debate about the nature of our obligations. (shrink)

Many philosophers accept that ought implies can (OIC), but it is not obvious that we have a good argument for that principle. I consider one sort of argument for it, which seems to be a development of an Aristotelian idea about practical deliberation and which is endorsed by, amongst others, R. M. Hare and James Griffin. After briefly rehearsing some well-known objections to that sort of argument (which is based on the supposed pointlessness of impossible obligations), I present a further (...) objection, based on a maximally charitable reading of the argument, and conclude that nobody ought to think that it gives them a reason to accept OIC.
