With a remarkable connection between social anthropology and psychoanalysis, Freud examines the individual within the crowd, as well as the crowd within the individual, the primary family and the great mass formations, the church and the army, and arrives at thoughts and conclusions that astonish with their originality and the definiteness of their expression.

This is also one of the far-reaching books, with which the psychoanalyst Freud becomes a teacher and enlightener, a continuator of the great tradition of Nietzsche, Schopenhauer, Feuerbach, Darwin, but also of Spinoza, Voltaire, and Diderot.
