The mind is a complicated system. According to psychologist Sigmund Freud's theory of psychoanalysis, the subconscious is composed of clashing and disputing extremes known as the id, ego, and superego.

While Jack and his tribe of savages are wearing little clothing, painting their faces, and tying back their hair, Ralph refuses to take part in this behavior for the sake of staying civilized and not looking "like a girl." The superego is also responsible for producing feelings of guilt. After Simon's death, Ralph...
