Abstract: Heidegger's existentialist view of language is ontological. Based on his distinction between existence and existent, Heidegger treats human beings as a special kind of existent, or linguistic existence, from which he further explores the meaning of existence and nature of truth. In this way the relationship between existence and language can thus be explained in a philosophical sense, where language divides and combines different forms of existence, which are simultaneously reflected in language itself, thereby making language a prerequisite for human beings to understand existence. Deeply shaking the western traditional view of existence founded on the objectified thought pattern, Heidegger's existential view of language is an irrationalist transcendence of the western traditional philosophy since the Platonic times, and makes the linguistic turn of western philosophy eventually come true.
