The third edition of this seminal work includes the original text, first published in 1974, the updates and reflections from the second edition and two groundbreaking new chapters. Power: A Radical View assesses the main debates about how to conceptualize and study power, including the influential contributions of Michel Foucault. The new material includes a development of Lukes's theory of power and presents empirical cases to exemplify this.  Including a refreshed introduction, this third edition brings a book that has consolidated its reputation as a classic work and a major reference point within Social and Political Theory to a whole new audience. It can be used on modules across the Social and Political Sciences dealing with the concept of power and its manifestation in the world. It is also essential reading for all undergraduate and postgraduate students interested in the history of Social and Political Thought.
