Faulkner's description of the characters' psychology in A Rose for Emily accords well with Freudian psychoanalytic theory, for there are similar conflicts among the id, the ego and the superego in the plot development. By analyzing several important characters in the novel through employing Freudian theory of human psyche, this thesis gives the explanation to the causes of the conflict and clash between Emily and the society, and then deeply explores the thematic concerns of the short novel.
