萨特在考察人的问题时把人放到人与人的关系中,指出:人与人的关系的不可超越性是人必须面临的关系。处在关系中的人之间的冲突消解了人是实现自由的可能性或者至少使这种可能性大打折扣。因而在自由是人的绝对需求的前提下,为了克服人与人之间关系对自由的压制,必须通过人的活动改变这种状况。因而人的活动成为克服矛盾的钥匙。 Sartre put people in the relationship between people when examining people’s problems and pointed out that the unsustainable relationship between people is a relationship that people must face. Conflict between people in relationships removes the possibility that one is free or at least greatly reduces that possibility. Therefore, under the premise that freedom is the absolute demand of human beings, in order to overcome the suppression of freedom by the interpersonal relationship, this situation must be changed through human activities. Thus human activity becomes the key to overcoming contradictions.
