The Possibility of Comparison between Concept of Human in Sadra Philosophy and Existential Philosophies (with Emphasis on Yaspers and Sartre's Ideas)

“Existence”، and “The Existence preceding the essence” are the key phrases in philosophy of Mollasadra and the existential philosophy. Because of this similarities، at first glance، it seems it is possible to have a comparative study between them. For examining this theory it is necessary to make the concept of human، and human existence clear and also it is necessary to study the approaches in atheistic existentialism (Sartre) and theistic existantialim (yaspers) and their goals، basis and main elements. The basic feature in existentialism in which human is the main subject، is returning to objective approach with phenomenological view which is kind of response to idealistic philosophies. But in the transcendent philosophy of mollasadra، human is regarded as his final direction witch is the god، and its philosophical approach is Foundationalism and accepting abstractive concepts. In mystic view of human which mollasadra is influenced by، human is the center of the universe and the whole being is because of him، but all of this is because he is related with the god. And this is the main differences with existential philosophies.
