In How Should Ethics Relate to (the rest of) Philosophy?, Stephen Darwall challenges both the claims of independence and priority. He argues that although metaethics and normative ethics are properly ...focused on different issues, they need to be brought into a dynamic relation with one another in order to produce a systematic and defensible philosophical ethics. Their mutual dependence, claims Darwall, is owing to the fact that issues of normativity are at the centre of the concerns of both metaethics and normative ethics. In making his case, Darwall examines Moore's doctrine that an irreducible notion of intrinsic value is fundamental in ethics, and argues that although Moore was correct in thinking that ethical notions are irreducible, he was incorrect in thinking that this is because they have a notion of intrinsic value at their core. Rather, according to Darwall, the notion of a normative reason is ethically fundamental, and a proper philosophical ethics that fully accommodates the normativity involved in ethical thought and discourse will require that metaethical issues and normative issues bearing on normativity be ‘pursued interdependently as complementary aspects of a comprehensive philosophical ethics’. He illustrates this claim by explaining how certain debates within normative ethics over consequentialism and over virtue depend upon metaethical issues about the nature of normativity.
Ludwig Wittgenstein’s On Certainty was finished just before his death in 1951 and is a running commentary on three of G.E. Moore’s greatest epistemological papers. In the early 1930s, Moore had ...written a lengthy commentary on Wittgenstein, anticipating some of the issues Wittgenstein would discuss in On Certainty. The philosophical relationship between these two great philosophers and their overlapping, but nevertheless differing, views is the subject of this book. Both defended the existence of certainty and thus opposed any form of scepticism. However, their defences and conceptions of certainty differed widely, as did their understanding of the nature of scepticism and how best to combat it. Stroll’s book contains a careful and critical analysis of their differing approaches to a set of fundamental epistemological problems.
