It’s well-known that “God is dead” is one of ideas of Nietzsche’s writings. According to my opinion, as talking about the death of God, Nietzsche uses two different narrative forms: one is the natural death of God; the other is that God is killed by human being. I believe that the second narrative form is the leading one in Nietzsche’s writings, because Nietzsche is not only against Christianity, but also looks down upon human being. Therefore, the key meaning of Nietzsche’s phrase “God is dead” relates to a paradox of relationship between the original evil of human nature and the activity which God saves human being. Obviously, it is not possible for the Western Christian culture to rid itself of its own crisis, if the paradox is not soled in advance.
Under the influence of traditional Western philosophy,orthodox interpreters distort Marx’s philosophy as the ontology of substance for a long time,in order to cover the essence of Marx’s philosophy,and to cancel the fundamental difference between Marx’s philosophy and the traditional philosophy.This paper points out that Marx’s philosophy isn’t the ontology of substance;On the contrary,through the sublimation of the ontology of substance,Marx puts forward his own ontology,i.e.,the ontology of praxis-relations of social production by which Marx combines the field of phenomenon with of essence to express the whole content and essence of his philosophy.
