"Freud is an interesting case in the history of psychology. To many he is the embodiment of cultural relativism, with the great emphasis he placed on the role of the parents and family in the shaping of an individual’s personality. However, Freud deserves mention for two reasons. First, unlike many subsequent psychologists Freud was interested in ultimate questions; he was preoccupied by finding out why people behaved as they did, not simply how. Second, although many of these accounts were distinctly non-Darwinian (e.g. the Oedipus complex in which a male child desires to kill his father), some of his ideas are much more in line with recent Darwinian psychology."
