Carl Gustav Jung (/ˈjʊŋ/; German: [ˈkarl ˈɡʊstaf ˈjʊŋ]; 26 July 1875 – 6 June 1961), often referred to as just C. G. Jung, was a Swiss psychiatrist and psychotherapist who founded analytical psychology. Jung proposed and developed the concepts of extraversion and introversion; archetypes, and the collective unconscious. His work has been influential in psychiatry and in the study of religion, philosophy, archeology, anthropology, literature, and related fields.
The central concept of analytical psychology is individuation – the psychological process of integrating the opposites, including the conscious with the unconscious, while still maintaining their relative autonomy. Jung considered individuation to be the central process of human development.
Jung created some of the best known psychological concepts including the archetype, the collective unconscious, the complex, and synchronicity. The Myers-Briggs Type Indicator (MBTI), a popular psychometric instrument, has been developed from Jung's theory of personality typology.
Jung saw the human psyche as "by nature religious" and made this religiousness the focus of his explorations. Jung is one of the best known contemporary contributors to dream analysis and symbolization.
Though he was a practicing clinician and considered himself to be 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. Jung's interest in philosophy and the occult led many to view Jung as a mystic, although Jung's ambition was to be seen as a man of science. His influence on popular psychology, the "psychologisation of religion", spirituality and the New Age movement has been immense.
