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.展开更多

It mainly portrays the downfall of Macbeth who transforms from a brave hero with nobility and loyalty to a ruthless demon with the interaction of the internal and external causes. This paper tries to find a reasonable explanation for his downfall by adopting the theories of Freudian psychoanalysis, and further reveal the desire's erosion to the conscience and morality's restraint to the desire in human nature. The id,the ego and the superego interact with each other. If any one of them is in imbalance with another,serious personality imbalance,or even personality split will occur.展开更多
