Carl Jung’s primary disagreement with Sigmund Freud stemmed from their differing concepts of the unconscious. Jung saw Freud’s theory of the unconscious as incomplete and unnecessarily negative.

Jung proposed the existence of a second, far deeper form of the unconscious. This was the collective unconscious, where the archetypes themselves resided, represented in mythology by a lake or other body of water…

The “personal” unconscious is a reservoir of experience unique to each individual, while the collective unconscious collects and organizes those personal experiences in a similar way with each member of the species.

In his book, Archetypes and the Collective Unconscious (p. 43), Jung says, “My thesis then, is as follows: in addition to our immediate consciousness, which is of a thoroughly personal nature… there exists a second psychic system of a collective, universal, and impersonal nature which is identical in all individuals. This collective unconscious does not develop individually but is inherited. It consists of pre-existent forms, the archetypes, which can only become conscious secondarily and which give definite form to certain psychic contents.”
