Then on the basis of western existential, we analyze definite meaning of the existential, explore the existential philosophy of the traditional philosophy plight of abandoned and beyond. Basing on this demonstration of the praxis category with the existential meaning. Marx pointed out in the innateness of human, natural fact, the natural state of survival reached the general attention, existential significance of praxis can be fully reflected. And explained that Marxist philosophy in the modern existential philosophy of the founders position.
