Carl Jung founded analytical psychology. Analytical psychology is based on the integration of conscious and unconscious motivations into displayed human behavior. It's development was based on psychoanalysis and the work of Sigmund Freud but investigated the unconscious more, creating a model of the collective unconscious.

Many of Carl Jung's psychological concepts and theories are still recognized and used in the field of psychology today, especially in the areas of personality and analytical psychology. While some of his ideas have been criticized and revised over time, many of Jung's findings continue to be influential in modern psychology.

Freudian psychoanalysis assumes that the repressed material hidden in the unconscious is given by repressed sexual instincts, Analytical psychology has a more general approach. There is no preconceived assumption about the unconscious material. The unconscious, for Jungian analysts, may contain repressed sexual drives, but also aspirations, fears, etc.
