Therefore, in this chapter, I will research into the conflict and contradiction of the paternity. Also, in this novel, the father's behavior of "He who loves well chastises well." is quite suspicious, one of the reasons is that the father thought his son belonged to him. And then, this thesis quoted Lacan's theory to touch upon that someone who has accepted the concept of patriarchal society, he will be influenced for his whole life. That also reveals that human being has no choice sometimes in this society.
因此本章会先就父子关系的冲突与矛盾做深入的探讨,小说中的父亲似有对儿子爱之深责之切的行为,其原因可能在於父亲将儿子视为所有物所致;其次,论文将引用拉冈相关理论,讨论在父权社会中,不论身分为何,只要是已受父权社会观念根深蒂固影响的人物,终生都将受其所苦,此也揭示出人生存於社会上的无奈。
