Robert Jay Lifton, the National Book Award-winning psychiatrist, historian, and public intellectual, proposes a radical idea: that the psychological relationship between extremist political movements and fanatical religious cults may be much closer than anyone thought. Exploring the most extreme manifestations of human zealotry, Lifton highlights an array of leaders - from Mao to Hitler to the Japanese apocalyptic cult leader Shoko Asahara to Donald Trump - who have sought the control of human minds and the ownership of reality.
