Heard is an authority on sociological history. This is the study of man's evolution to the present, with suggestion of the paths he must tread in the future. His thesis is that man has evolved through two stages, the one physical, the other technical, and that he has reached completion along these lines. Now he must develop psychically, and his present inner conflict is responsible for the confusion of the world today. Society is composed of a mass of individual neuroses -- unresolved. Heard traces the role of the evolution of consciousness through Greek, Hebrew, Egyptian cultures: then shows how by various techniques, both individual and group, this evolution can be accomplished today. Not a book for one's lighter moments.
