萨特认为,哲学就是“人学”。他把“人”作为哲学研究的对象,值得重视,但把“人”归结为孤立的个人存在和主观意识,则使他滑向唯心主义。他从“人的存在状态”、“人生的体验”对人作了分析,说明人是虚无的存在,“恶心”是人生的体验和证明,表现了他的悲观主义。 Sartre believes that philosophy is “human learning.” He regards “man” as the object of philosophical study, which deserves our attention. However, reducing “man” to his isolated individual existence and subjective consciousness leads him to idealism. He analyzed human beings from the state of human existence and the experience of human life, which shows that man is nothingness. Nausea is the experience and proof of life, which shows his pessimism.
