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).
Augustan prose
Also in contrast to the Restoration, when philosophy in England was so fully dominated by John Locke that few other voices are remembered today, the 18th century had a vigorous competition among followers of Locke, and philosophical writing was strong. Bishop George Berkeley and David Hume are the best remembered major philosophers of 18th-century England, but other philosophers adapted the political ramifications of empiricism, including Bernard de Mandeville, Charles Davenant, and Adam Smith. All of these figures can be considered empiricists, for they all begin with the relative certainty of perception, but they reach vastly different conclusions.
