"This book is a wonderful collection of essays related to moral skepticism . . . The essays are of a very high quality, written by a who's-who of philosophers doing exciting contemporary work in metaethics. They summarize the current state of the literature on moral skepticism and push that literature forward along many fronts . . . Any researcher interested in skeptical themes in metaethics will find this an invaluable resource . . . I recommend it strongly." – Matt Lutz in Notre Dame Philosophical Reviews"The book will be most helpful for advanced students already acquainted with the debates it covers and eager to engage with recent developments. It will be essential reading for those suspicious of the apparent commitments of morality and wondering where that suspicion might take them." – Neil Sinclair in the International Journal for the Study of Skepticism
