Eastern philosophy
The "Dao De Jing" ("Tao-Te-Ching," c. 4th century BCE), traditionally attributed to Laozi, and the "Nan Hua Jing" ("Zhuang Zi") are considered the key texts of the tradition. The first organized form of Taoism, the Tianshi (Celestial Masters') school arose in the 2nd century CE. Xuanxue ("deep learning", also "Neo-Taoism") was a major philosophical movement influenced by Confucian scholarship, which focused on the interpretation of the "Yijing," "Daodejing," and "Zhuangzi" and which flourished during the third to sixth centuries CE. The most important philosophers of this movement were He Yan, Wang Bi, the Seven Sages of the Bamboo Grove, Ge Hong and Guo Xiang. Thinkers like He Yan and Wang Bi focused on the deep nature of Tao, which they saw as being best exemplified by the term "Wu" (nothingness, non-being, negativity).
Eastern philosophy
Following the Xinhai Revolution in 1911 and the end of the Qing Dynasty, the May Fourth Movement sought to completely abolish the old imperial institutions and practices of China (such as the old civil service system). There were two major philosophical trends during this period. One was anti-traditional and promoted Western learning and ideas. A key figure of this anti-traditional current was Yan Fu (1853–1921) who translated various Western philosophical works including Smith's The Wealth of Nations and Mill's On Liberty. There were also attempts to incorporate Western ideas of democracy, and republicanism into Chinese political philosophy, notably by Sun Yat-Sen (1866–1925) at the beginning of the 20th century. Another influential modern Chinese philosopher was Hu Shi, who was a student of John Dewey at Columbia University and who promoted a form of pragmatism.
