 Jung gives a brief account of the historical development of Psychoanalysis, particularly Freud and Breuer’s case history of Anna O, and covers some of Freud’s early theorizing on neurosis, the unconscious, dream interpretation, wish fulfillment, and the incest-wish of the Oedipus Complex.While Freud explained neurosis through sexual motivations, Adler explained those same conflicts as arising from a power principle.Jung addresses Adler’s concepts of superiority/inferiority and compensation and Nietzsche’s writings on the will to power.
