Since its publication in 1974, Power has consolidated its reputation as a classic work and a major reference point within social and political theory by assessing the main debates about how to conceptualize and study power. New to the Revelations series, this revised edition presents a brand new introduction by Steven Lukes on the nature of the power debate in the world today. It includes the original text from the first and all subsequent editions, and is essential reading for anyone interested in the concept of power.
