Heidegger's Poetic Save

In Heidegger's opinion,in metaphysics, entity is regarded as Being and Being is forgotten. Metaphysics is essentially metaphysics of subjectivity,which generalize the world as the picture of Man.Man places himself in rootlessness.The development of science and modern technology speeds up and deepens this state .According to Heidegger's view, the essence of Man belongs to Being. Being is the totality of the quart-level-whole of heaven > earth >. god and man. Being that can be understood is language. Language is the home of Being. Heidegger's language is essentially poetry. Therefore,Heidegger' idea is essentially poetic .The true poetry is the saying of Being .We must hear the saying of the true poetry and poetically dwell upon the earth .They advise us to own a kind of life attitude and style: let substance work freely and turn our heart to mystery .Therefore,only poetry can make us dwell upon the earth. Poetic life becomes our hope of save. Heidegger's idea is very important for our technologizable and formalizable era.But there exists some difficulties in Heidegger's idea: it doesn't overcome metaphysics, not find a proper way to connect poetic life with actual life ; It lets the few poets assume the burden of human saving but apt to open the way to religion.
