Structural theory

Structural theory divides the psyche into the id, the ego, and the super-ego. The id is present at birth as the repository of basic instincts, which Freud called " Triebe " ("drives"). Unorganized and unconscious, it operates merely on the 'pleasure principle', without realism or foresight. The ego develops slowly and gradually, being concerned with mediating between the urging of the id and the realities of the external world; it thus operates on the 'reality principle'. The super-ego is held to be the part of the ego in which self-observation, self-criticism and other reflective and judgmental faculties develop. The ego and the super-ego are both partly conscious and partly unconscious.
