Carl Jung believed that dialogue between the conscious and unconscious mind enriches people. He coined the term "individuation" to describe personal development involving a connection between the ego and self. Jung identified four main psychological functions: thinking, feeling, sensation, and intuition. He also distinguished between introversion and extraversion in people's orientations. Jung proposed a personal unconscious similar to Freud's, as well as a deeper collective unconscious containing innate archetypes shared between all people.
