Jung taught that the psyche consists of various systems including the personal unconscious with its complexes and a collective unconscious with its archetypes. Jung’s theory of a personal unconscious is quite similar to Freuds creation of a region containing a person’s repressed, forgotten or ignored experiences. However, Jung considered the personal unconscious to be a “more or less superficial layer of the unconscious.” Within the personal unconscious are what he called “feeling-toned complexes.” He said that “they constitute the personal and private side of psychic life.”3 These are feelings and perceptions organized around significant persons or events in the person’s life.
Jung believed that there was a deeper and more significant layer of the unconscious, which he called the collective unconscious, with what he identified asarchetypes, which he believed were innate, unconscious, and generally universal. Jung’s collective unconscious has been described as a “storehouse of latent memory traces inherited from man’s ancestral past, a past that includes not only the racial history of man as a separate species but his pre-human or animal ancestry as well.”4 Therefore, Jung’s theory incorporates Darwin’s theory of evolution as well as ancient mythology. Jung taught that this collective unconscious is shared by all people and is therefore universal. However, since it is unconscious, not all people are able to tap into it. Jung saw the collective unconscious as the foundational structure of personality on which the personal unconscious and the ego are built. Because he believed that the foundations of personality are ancestral and universal, he studied religions, mythology, rituals, symbols, dreams and visions.
He says:
“All esoteric teachings seek to apprehend the unseen happenings in the psyche, and all claim supreme authority for themselves. What is true of primitive lore is true in even higher degree of the ruling world religions. They contain a revealed knowledge that was originally hidden, and they set forth the secrets of the soul in glorious images.5
