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).
British philosophy
The three 'classic' British empiricists in the early modern era were John Locke, George Berkeley, and David Hume. The term "British empiricism" refers to the philosophical tradition in Britain that was epitomised by these thinkers (though this tradition did have precursors in Britain stretching back to Roger Bacon). Berkeley, despite being Irish, was referred to as British as County Kilkenny, where he lived in Ireland, was a part of the United Kingdom of Great Britain and Ireland at the time.
