Carl Gustav Jung ( /ˈjʊŋ/; Kesswil, July 26, 1875 - Küsnacht, June 6, 1961) was a Swiss psychiatrist and psychotherapist who founded analytical psychology. Jung proposed and developed the concepts of the extroverted and introverted personality, archetypes, and the collective unconscious. His work has been influential in psychiatry, psychology, and the study of religion, literature, and related fields.
The central concept of analytical psychology is individuation - the psychological process of integrating opposites, including the conscious with the unconscious, while maintaining their relative autonomy. Jung considered individuation to be the central process of human development.
He created some of the best known psychological concepts, including the archetype, collective unconscious, ocomplex, and synchronicity. The Myers Briggs Typological Classification (MBTI), a popular psychometric instrument, was developed from his theories.
He saw the human psyche as "symbolic in nature," and made this symbolism the focus of his explorations. He is one of the greatest known contemporary contributors to dream analysis and symbolism. Although he practiced his profession as a physician and considered himself a scientist, much of his life's work was spent exploring tangential areas, including Eastern and Western philosophy, alchemy, astrology, and sociology, as well as literature and the arts. His interest in philosophy and the occult led many to view him as a mystic.
