This Handbook surveys the contemporary state of the burgeoning field of metaethics. Forty-four chapters, all written exclusively for this volume, provide expert introductions to:

the central research programs that frame metaethical discussions

the central explanatory challenges, resources, and strategies that inform contemporary work in those research programs

debates over the status of metaethics, and the appropriate methods to use in metaethical inquiry

This is essential reading for anyone with a serious interest in metaethics, from those coming to it for the first time to those actively pursuing research in the field.
