This paper aims at: 1. to investigate two views of nature from contrast ofinner end and outer end. 2. to illustrate the fact that Hegel's philosophy of nature is to think of the nature "speculatively". In other words, what Hegel wants to do is to recon-cile with the nature. 3. to discuss Hegel's critique on Ionian school, Anaxa-goras, Aristotle and Schelling in order to make clear Hegel's own view. 4. to point out the significance of Hegel's philosophy of nature in contemporary society.
