This diagram represents the divisions of the unconscious and conscious mind.
The broad base of the pyramid is occupied by biology, which pre-organizes human life according to common structures or schemata, which are permanent and unchanging.

Pyramid of the unconscious

The next level is occupied by Culture, which provides the pre-existing structures or patterns that enable us to meet our biological needs. Archetypes reside at this level of the unconscious. Together they form the collective unconscious described by Jung. Cultures last for centuries and charge almost imperceptibly.

The next level of the pyramid represents the Person, the individual unconscious. As we assimilate language and archetypal structures, and the emotions associated with them, our personality gives these different weights and values. Part of these experiences will slip from memory but linger in our individual unconscious. Each individual unconscious is unique, and it is accessible only through psychoanalysis. The individual unconscious lasts the length of a person's life.

The part of the pyramid above this level represents the emergence of the superego and the beginning of consciousness, which is comprised of Behavior (how we act, what we do) and Opinion (what we think, what we say). Both are sustained and shaped by the unconscious forces that underlie them. Behavior can change readily (how we act is subject to continuous revision) but Opinion, which has the shortest life of all, can change in the blink of an eye (whenever new information is presented).
