The ego ideal as a distinct entity related to, but separate from, the superego is discussed. This distinction is highlighted during times of change and transition as in the preoedipal and early adolescent periods. The ego ideal is seen as a restitutive phenomenon used to support and cope with ego weakness, i.e., a projected wish. A review of the normal development and vicissitudes of the ego ideal from infancy through adolescence is presented. The author's main point is that during treatment there is a stage when the adolescent needs to idealize the therapist in order to derive an external source of strength. To deal too quickly on a reality basis with this projection of ego ideal deprives the adolescent of the external bolstering he needs. On the other hand, as the adolescent ego becomes stronger he will have to deal with the disappointment of discovering that his therapist is, after all, only human.
