Existentialism : St Thomas Aquinas versus Jean-Paul Sartre

Thomas Aquinas and Jean-Paul Sartre present different vision of the philosophy of existence. Thomas points out the existence of a being of its own necessity, a God, who is fundamental and central for his reflection on human being, while Sartre considers the non-existence of God as necessary for human being. For Thomas, God is the very core of human freedom and values, while according to Sartre, human freedom denies God, and norms and values are in facts only conventional. It turns out that all the differences on the matter of anthropology and ethics at both of the philosophers are due to different metaphysical attitudes and a fundamental disagreement between atheism and theism.
