本文旨在从伊曼努尔·列维纳斯“他者伦理学”视角探索科马克·麦卡锡普利策获奖小说《路》中的好人准则。好人准则贯穿整个小说，对后启示录世界中伦理秩序的重塑有指导性意义。列维纳斯“他者伦理学”介绍了自我与他者的伦理关系，与好人准则的内涵相契合。 根据列维纳斯的理论，伦理关系始于他者的他异性，他者他异性优先于自我存在,承担对他者的责任是建构自身主体性的前提。在现实的人际关系中，他者的他异性命令人们通过承担对他人的责任来建立伦理关系。在小说《路》中，好人准则可以分为对他人负责的准则和对自我生存的准则。然而，对他人负责和自我生存相互矛盾，遵循对他人负责的准则在后启示录世界中会危及自我生存，而将自身生存作为唯一目标会导致伦理丧失。列维纳斯的“他者伦理学”受到挑战。面对选择对他人责任还是自我生存的困境，幸存者做出了不同的选择。食人族选择自我生存，不惜以他人生命为代价；父亲将生存问题放在首位但不主动伤害他人；儿子选择对所有人负责,尽管自己的生命岌岌可危。在这三种选择中，儿子遵循好人准则来重塑伦理秩序的做法是防止人类灭绝的唯一希望，列维纳斯他者先于自我存在的伦理关系仍具有决定性力量。他者是等待被实现的“善”的载体，所以回应他者的他异性是实现“善”的必要条件,呼应了小说中麦卡锡对“善”的诉求。

This thesis aims to explore the code of good guys in Cormac McCarthy’s Pulitzer-winning novel The Road from the perspective of Emmanuel Levinas’s ethical theory. The code of good guys penetrates the whole novel and plays a directive role in restoring ethics in the post-apocalyptic world. Levinas’s ethics interprets the establishment of ethical relationship with the Other, coinciding the implication of the code of good guys. According to Emmanuel Levinas, ethical relationship is initiated by the alterity of the Other which precedes one’s own being. Assuming one’s responsibility for the Other is the precondition to singularize one’s subjectivity. In the real-world interpersonal relationship, the alterity of the Other commands a person to assume his responsibility for others---other people, to establish ethical relationships. In The Road, the code of good guys can be divided into the code of responsibility for others and the code of survival. However, responsibility for others and one’s own survival are contradictory with each other. Following the code of responsibility for others in the post-apocalyptic world can endanger one’s own survival while living only for one’s survival can cause bankruptcy of ethics. Thus, Levinasian ethics is challenged. Confronting the dilemma of whether to choose ethics or survival, survivors make different choices. The cannibals live only for their survival at the cost of other people’s lives. The father regards survival as priority but does not harm others initiatively. The son chooses to answer the call of all even if his own life is at stake. Among all the three choices, the son’s choice of following the code of good guys to restore ethics bears the only hope to prevent human beings from extinction. The Levinasian ethical Self/Other relationship that the Other is prior of one’s own being still has determinative power. The Other is an embodiment of goodness to be realized, so responding to the Other is also imperative to realize the Good, which echoes McCarthy’s appeal for goodness in the novel.
