This is an edited excerpt from Chapter 22, titled "Ideological Totalism," of Robert Jay Lifton's book, Thought Reform and the Psychology of Totalism: A Study of 'Brainwashing' in China. Lifton, a psychiatrist and distinguished professor at the City University of New York, has studied the psychology of extremism for decades. He testified at the 1976 bank robbery trial of Patty Hearst about the theory of "coercive persuasion." First published in 1961, his book was reprinted in 1989 by the University of North Carolina Press (Chapel Hill and London). Lifton's analysis of "thought-reform" applied to cultic behavior is very instructive in our present space-time.
