FIGURE 1.2 • Freud’s Iceberg Metaphor of the Organization of the Mind Freud proposed that the mind is made up of three structures: id, ego, and superego. Each person is aware (conscious) of some of what is in his or her ego and superego; some of the preconscious contents of the ego and the superego can be brought into awareness, and some of those contents—along with all of the id—remain unconscious.
