The Ego is in a relationship with the id resembling that between a rider and his horse. The horse provides the locomotor energy, and the rider has the prerogative of determining the goal and of guiding the movements of his powerful mount towards it. But all too often in the relations between the ego and the id we find a picture of the less ideal situation in which the rider is obliged to guide his horse in the direction in which it itself wants to go.
The Ego is not simply a defensive product of the self-preservative reality principle, but is rather a structured sedimentation of lost objects... such lost loves are, in turn, incorporated into the tissue of subjectivity itself.
The Ego is by no means a unity, though we are forced to regard it as one, but, in the highest degree it is a manifold world, a constellated heaven, a chaos of forms, of states and stages, of inheritances and potentialities.
The Ego is a substratum with no reality... it is merely a symbol intended to unceasingly recall to our consciousness the artificial character of the process by which the attention places clean-cut states side by side, where actually there is a continuity which unfolds.
