巴尔加斯·略萨“生存意识”的产生有多方面原因：首先是拉美文学“干预现实与政治”的传统影响。这使巴尔加斯·略萨认识到作家应通过文学作品对现实加以描绘和谴责，唤起人们变革现实的勇气和希望。因而他自觉地秉承了作家对社会的道义责任，试图引起大家对人们生存状况的关注；其次是深层无意识动机的激活。巴尔加斯·略萨和母亲曾被在家中表现如同暴君一般的父亲遗弃。他的弑父欲望一直潜伏在无意识深处。后来他对人民生存的现实不满使一直深藏在心中的弑父情结在无意识中被激活，并有了合乎社会道德规范的释放途径；最后是西方人本主义思潮的熏陶。巴尔加斯·略萨对西方各种流派的人本主义耳濡目染。他在汲取精华的基础上，找到了个体的位置。 There are many reasons why Vargas Llosa’s “Survival Consciousness” came from: firstly, the traditional influence of Latin American literature “Intervention in reality and politics”. This made Vargas Llosa realize that writers should depict and condemn the reality through literary works and arouse the courage and hope of people to reform the reality. Therefore, he conscientiously upholds the author’s moral obligation to society and tries to arouse people’s attention to people’s living condition. Secondly, it is the activation of deep unconscious motivation. Vargas Llosa and her mother were abandoned at home by tyrant-like fathers. His patricide’s desires are lurking in the unconscious. Later, his dissatisfaction with the reality of the people’s existence made the Father’s Complex, which had been deeply hidden in his heart, activated unconsciously and had a release route in conformity with social moral norms. Finally, it was influenced by Western humanism. Vargas Llosa influenced the humanism of all schools in the West. He found the essence based on the individual’s position.
