This monumental work, complete here in one volume, undertakes to determine scientifically what distinctive personality traits characterize the phenomenon of prejudice. The authors' purpose is to discover the social psychological factors which have made it possible for the authoritarian type of man - a new concept of an "anthropological" species - to threaten the survival of the individualistic and democratic type prevalent in the past century and a half of our civilization. The book mobilizes the skills of the different branches of the social sciences in one common research program. Experts in the fields of social theory and depth psychology, depth analysis, clinical psychology, political sociology and projective testing have pooled their methods and resources. Working in the closest cooperation, they here present a detailed picture of the authoritarian type of man. By isolating the destructive germ of the authoritarian personality, the book lays a major foundation for long-range attack upon the anti-democratic forces in modern society. (from the back cover.)
