The development of personality in the body takes three distinct forms as suggested by Freud in Hall’s summary of the id, ego, and superego. Their cooperation and ability to affect each other allows the body to become the vehicle subjected to the physical consequences of the personality’s decisions. In some respects, these consequences are banal, simple givens in our everyday life. This seems typical of the id. Tensions or discomfort brought about by bodily functions stimulate the id. The body requires release from this tension, what Freud calls the pleasure principal and reflex action, something the body learns to control early on in life. While the id deals with these essential body functions, the true psychological release of tension occurs with the ego. Here, the reality principal maintains control of the body as it seeks something tangible. The ego, as explained by Hall, is clearly the most subjective and personal of the three personality characteristics. Where the superego is something more of a control, or a blurry boundary for the ego, the ego is the one which can rise or fall to generate extreme and desired circumstance. This is the system that allows for actions like suicide or public bravado, those which breach any predetermined line of acceptance. Ego is a driving force in architecture, embodied in infinite ways. Often, it seems as though architecture needs the ego to be driven to the extreme in order to develop unexpected or previously unknown results. While this is useful and acceptable, the superego has its place as well. Where the ego pushes boundaries, the superego encourages that which is fundamentally acceptable, urging utility across all boundaries.
