Steven Lukes' Power: A Radical View is a seminal work still widely used some 30 years after publication. The second edition includes the complete original text alongside two major new essays. One assesses the main debates about how to conceptualize and study power, including the influential contributions of Michel Foucault. The other 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.
