William Golding’s Lord of the Flies, explores the depths of human nature. These aspects of the psyche can be discussed in Freudian terms. The ID, according to Freud, the founder of psychoanalysis, describes the primitive, instinctual aspect of human nature, and the novel suggests that without the rules of society, humans would revert to this level of development.
The Superego represents the opposite end of the two— spectrum, the moral aspect of human nature, and the EGO is the bridge between the the unrealistic ID and reality, the part of human nature that runs on logic. All the major characters in Lord of the Flies can be discussed in these Freudian terms.
