萨特是作为存在主义人学理论家为人们所熟知,但却很少有人深入研究过其哲学与道德学说的逻辑脉络。本文力图从本体论高度对萨特的道德哲学做些探讨,以揭示这种道德理论的形而上学基础、内在矛盾、新的转向和出路。 Sartre, as a well-known existentialist theorist, seldom studies the logic of his philosophical and moral doctrine. This thesis attempts to probe Sartre ’s moral philosophy from an ontological level to reveal the metaphysical foundation, internal contradictions, new directions and ways out of this moral theory.
