In Jungian psychology, archetypes are highly developed elements of the collective unconscious. Being unconscious, the existence of archetypes can only be deduced indirectly by examining behavior, images, art, myths, religions, or dreams. Carl Jung understood archetypes as universal, archaic patterns and images that derive from the collective unconscious and are the psychic counterpart of instinct. They are inherited potentials which are actualized when they enter consciousness as images or manifest in behavior on interaction with the outside world. They are autonomous and hidden forms which are transformed once they enter consciousness and are given particular expression by individuals and their cultures.
