This work investigates the fundamental nature of value and how it is inextricably linked to the social and historical conditions of human agency. Joseph Raz, a prominent philosopher of law and ethics, presents a framework that examines how values are not merely abstract concepts but are shaped by the environments in which individuals act. The book synthesizes his Tanner Lectures with critical responses from other leading philosophers to provide a multifaceted analysis of moral and social value.

Experts recognize this volume as a significant contribution to contemporary value theory, particularly for its rigorous engagement with the social dimensions of morality. Readers frequently note the academic density of the prose, which is intended for those with a background in moral philosophy.
