所罗曼诺瑟普的自传小说《为奴十二年》展示了19世纪50年代奴隶们最真实的苦难生活,也揭露出奴隶的痛苦大部分是来自奴隶主的残酷人性。而对《为奴十二年》的研究却很少有人在小说文本的基础上从精神分析的角度来探索小说中人物的人性。因此,本文将基于弗洛伊德的人格结构理论对小说人物Epps进行人格结构解读,探讨他邪恶膨胀的本我及其形成的原因。 The autobiographical novel “The Slave Twelve Years,” by Roman Opup, shows the most real misery of slaves in the 1850s and reveals that most of the pain of slaves comes from the cruel humanity of slave owners. However, few studies of “slave for 12 years” have seldom explored the human nature of characters in the novel from the perspective of psychoanalysis on the basis of novel text. Therefore, based on Freud’s theory of personality structure, this dissertation will analyze the personality structure of the novel Epps and probe into his own evil expansion and the reasons for its formation.
