在研究萨特存在主义的马克思主义的理论平台上,始终未曾真正解决的一个问题是萨特与马克思主义之间的关系。萨特自认接受了马克思主义的基本观点,但又明确指出马克思主义内部存在着严重的理论匮乏,他的存在主义将是一种重要的理论补充。这是一种十分奇特而难解的关系。本文就对萨特的存在主义和马克思主义关于人的本质方面进行相互比较,以便从中可以窥探出两者的联系与区别。 One problem that has never really been solved in the study of Sartre’s Marxist theoretical platform is the relationship between Sartre and Marxism. Sartre accepted the basic Marxist viewpoints, but clearly pointed out that there is a serious lack of theory within Marxism. His existentialism will be an important theoretical supplement. This is a very strange and intractable relationship. This article compares Sartre’s existentialism and Marxism’s essence with respect to human beings so that the connections and differences between the two can be seen.
