Considerable and successful efforts have been made in this country as well as in Europe to raise the various disciplines dealing with man as a social phenomenon at the organizational level of cooperation that has been a tradition in natural sciences. Experts in the fields of social theory and depth psychology, content analysis, clinical psychology, political sociology, and projective testing pooled their experiences and findings. Having worked together in the closest cooperation, they now present as the result of their joint efforts the elements of a theory of the authoritarian type of man in modern society. Ideologies have an existence independent of any single individual; and those which exist at a particular time are results both of historical processes and of contemporary social events. In modern society, despite enormous communality in basic culture, it is rare for a person to be subjected to only one pattern of ideas, after he is old enough for ideas to mean something to him.
