Four Faces of Moral Realism

This article explains for a general philosophical audience the central issues and strategies in the contemporary moral realism debate. It critically surveys the contribution of some recent scholarship, representing expressivist and pragmatist nondescriptivism (Mark Timmons, Hilary Putnam), subjectivist and nonsubjectivist naturalism (Michael Smith, Paul Bloomfield, Philippa Foot), nonnaturalism (Russ Shafer-Landau, T. M. Scanlon) and error theory (Richard Joyce). Four different faces of 'moral realism' are distinguished: semantic, ontological, metaphysical and normative. The debate is presented as taking shape under dialectical pressure from the demands of (i) capturing the moral appearances; and (ii) reconciling morality with our understanding of the mind and world.
