Jung, Carl

A Swiss psychologist of the twentieth century, who broke with his teacher Sigmund Freud and developed his own theories. Jung denied that sexuality is the basic driving urge for people. He classified people as extroverts and introverts, put forth a theory of the feminine principle in men (the anima) and the masculine principle in women (the animus), and argued that people share a collective unconscious, made up of symbols (see also symbol) called archetypes.
