The internal triangle of maternal imago, paternal imago, and self is unique to female development. Girls are “organless,” and because they can neither suckle their mothers nor penetrate their fathers, they gain control by introjecting both parental objects. The introjection of the preoedipal mother is a primitive incorporation, an oral pre-identification in which mother is ingested with her milk. The internalization of the oedipal father is more highly evolved, a relationship to, as well as a mental representation of, the object. Within the complex endopsychic feminine world, girls freely discharge both libido and aggression toward internalized objects.
