Prudential Normativity, Moral Scepticisms, and Metaethics

In earlier chapters it was argued that prudential value gives agents normative, prudential reasons and that prudential judgements are normative judgements on a par with moral judgements. This chapter spells out some ramifications of these theses by examining four different areas of inquiry about morality and moral discourse, showing how the theses hitherto defended in this book affect them. It begins with the form of moral scepticism found within the ‘why be moral?’ debate. It then examines hermeneutic moral error theory and proposes a companions-in-guilt argument based on the normativity of prudential discourse. Third, it examines arguments given within the literature on revisionary metaethical views, pointing out and questioning their commitment to prudential justifications. Finally, it is shown how the normativity of prudential properties applies to a central debate about thick concepts, that between reductionists and non-reductionists about such concepts.

Moral Error Theory Without Epistemic Error Theory: Scepticism About Second-Personal Reasons

Proponents of the epistemic companions in guilt argument argue that we should reject the moral error theory because it entails that there are no epistemic reasons. In this paper, I investigate whether a plausible version of the moral error theory can be constructed that does not entail an error theory about epistemic reasons. I argue that there are no irreducibly normative second-personal reasons even if there are irreducibly normative reasons. And epistemic reasons are not second-personal reasons. In this case, a plausible version of the moral error theory can be constructed that does not entail an error theory about epistemic reasons if facts and claims about morality entail facts and claims about irreducibly normative second-personal reasons. And, as I explain, there is a good case that facts and claims about morality do entail facts and claims about irreducibly normative second-personal reasons.
