This second edition of a seminal work includes the original text, first published 30 years ago, alongside two major new chapters. Power, Freedom and Reason assesses the main debates about how to conceptualize and study power, including the influential contributions of Michel Foucault. Power Revisited reconsiders Steven Lukes' own views in light of these debates and of criticisms of his original argument. With a new introduction and bibliographical essay, this book will consolidate its reputation as a classic work and a major reference point within social and political theory.
