"This book will be of great interest to philosophers who advocate or oppose constructivist views, particularly of the global sort... readers unversed in the topic of metaethical constructivism should come away with a good sense of what is at stake in contemporary debates, while specialists will find a wide range of fruitful and challenging ideas with which to engage deeper and explore further." --Journal of Moral Philosophy
