Carl Gustav Jung (26 July 1875 – 6 June 1961) was a Swiss psychiatrist, an influential thinker and the founder of Analytical Psychology. Jung is considered the first modern psychiatrist to view the human psyche as "by nature religious" and make it the focus of exploration. Though not the first to analyze dreams, he is one of the best known researchers in the field of dream analysis and symbolization. While he was a fully involved and practicing clinician, 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; all of which were extremely productive in regard to the symbols and processes of the human psyche, found in dreams and other entries to the unconscious.
Jung considered the process of individuation necessary for a person to become whole. This is a psychological process of integrating the opposites including the conscious with the unconscious while still maintaining their relative autonomy. Individuation was the central concept of analytical psychology.
Many psychological concepts were originally proposed by Jung, including the Archetype, the Collective Unconscious, the Complex, and synchronicity. A popular psychometric instrument, the Myers-Briggs Type Indicator (MBTI), has been principally developed from Jung's theories.
I don't want happiness by halves, nor is half of sorrow what I want. Yet there's a pillow I would share, where gently pressed against a cheek like a helpless star, a falling star, a ring glimmers on the finger of a hand.
