The classic study of the process of dehumanization, released during the Cold War in 1987, follows social psychologist Sam Keen as he unmasks how individuals and nations dehumanize their enemies to justify the inhumanity of war. Using archival news footage, public service announcements, and editorial cartoons, Keen unveils the same frightening pattern in conflict after conflict - World War II, the Vietnam War, the Cold War, Islamic and Christian Fundamentalism - and prefigures the current War on Terrorism. First we identify ourselves as victims. Then we blame, demonize and finally dehumanize our adversaries, rationalizing our murder of other human beings. Psychologists Robert Lifton and Steven Kull explain how war and artificial enemies provide people with the moral and mental certainties they crave, giving them a sense of purpose in a sometimes-ambiguous world. Mythologist Joseph Campbell, providing a note of hope, suggests that underneath the mask of the enemy we ultimately recognize ourselves. This, Campbell further contends, may be the origin of compassion, brotherhood and altruism, in other words the inverse of war.
