Abstract

This book is a systematic defense of a nonnaturalist, intuitionist moral realism. It supplies an account of moral facts according to which moral value is supervenient, undefinable, and nonreducible. The author also argues that "we must accept without proof some claim to the effect that a given thing is intrinsically good or bad if we are to prove that anything at all is so". The project is explicitly in the tradition of philosophers such as Brentano, Moore, and Ross. The author focuses on developing his views rather than engaging in current debates by explicit reference to other work in value theory. The account is responsive to what one might take to be the most significant objections to it, but there are few references to specific arguments of recent and contemporary philosophers. On the one hand, this helps maintain the tightly interwoven systematic character of the account; but on the other, those not already disposed to accept some of its main claims may not find the articulation and defense of them compelling.
