Karen Horney, one of the first few women disciples of Freud and one of the pioneers of Psychoanalysis, was a rebel. As her biographer Susan Quinn says, she always had “a mind of her own.” Horney challenged Freud’s views of women and insisted that the socio-cultural context and the events of a historical moment contribute to the development of human personality. In other words, personal psychology does not originate only “inside the mind” but is strongly impacted by external factors. Her views on women and her views on the importance of cultural factors prompted other analysts to reject her theories and expel her from the official circles of Psychoanalysis. But later developments in Psychoanalysis vindicated her perspectives. Her views continue to be influential today. She emigrated to the U.S. from her native Germany in the early 1930s because of the Nazi take over. Later in her life, she became very interested in Zen Buddhism. Her writings are accessible and thought-provoking despite her strong Psychoanalytic terminology and wording. In this presentation, we will discuss her life, ideas, and most important writings and contributions to psychology and feminist thought.
