Carl Gustav Jung

Jung, Carl Gustav (1875–1961), Swiss psychiatrist, founder of analytical psychology. Jung's work on mental complexes brought him into contact with Sigmund Freud in 1907, a relationship that lasted until 1912, when Freud broke with Jung upon the publication of Jung's Psychology of the Unconscious. In this book Jung argued that there were two components of the unconscious: repressed or forgotten information of an individual's life and collective information shared by all human beings or by those in particular cultural groups. In 1921 Jung expounded on introversion and extroversion in Psychological Types. Jung believed that harmony between the conscious and unconscious was the most important psychological goal for the individual.
