Because of this theoretical separation between the small definable portion of being and the large, uncontrolled subconscious portion, Freud offers the topographically apt analogy of the iceberg, where the tiny visible portion at the top obscures the size and power of the submerged aspect. In technical Freudian terms, the portion nearest the surface of the water - personality - is called the ego. Just below the ego, nearing the bottom, is the superego, the part of a person's interiority that offers moral or social restraint against the unknown, unauthorized impulses of the subconscious. Finally, the greatest portion of the hidden mass is the id, the darkest, most recessed province of human thought, motivation and desire.

Researching and studying Freud's theory has helped me to expand my knowledge of human behavior. Additionally, it has helped me to develop a deeper understanding of Seb's subconscious impulses and motives.

These changes help the individual to find an identity, which means developing an understanding of self, the goals one wishes to achieve and the work/occupation role. The individual craves for encouragement and support of caretakers and peer groups. If he is successful he will develop a sense of self or identity, otherwise he will suffer from role confusion/ identity confusion.

This explains why the group changes their moral views so quickly throughout the course of the play. During this stage of their adolescence their identities are constantly developing and changing, which in turn creates a never-ending cycle of different perspectives and subconscious personality shifts.
