Abstract

This chapter explores the attractions, problems, and prospects of moral realism. Special attention is given to Moore’s Open Question Argument, internalism, noncognitivism, and error theories. The final section sketches a research program for moral realism that takes on and pursues Hume’s aim of explaining the ability to think in moral, and more broadly, normative, terms in a way that shows that the successful exercise of this ability is neither metaphysically nor epistemically mysterious.
