AT 9-001_FA22: Sigmund Freud was one of the most influential, and most controversial, figures of the twentieth century. In the eighty plus years since his death, many of Freud?s theories have been challenged and rejected by psychologists and neuroscientists. His ideas, however, continue to be influential in psychotherapy and in a variety of other academic disciplines. They have also had a profound impact on American and European literary and artistic forms, as well as on popular culture as a whole. While a majority of psychologists might reject the existence of an Oedipal Complex, this term, as well concepts such as id, ego, repression, oral and anal fixations, and ?Freudian slips? are all still part of our common vocabulary and our sense of how human beings work.
