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).
Anarchism in the United States
Historian Wendy McElroy reports that American individualist anarchism received an important influence of three European thinkers: "One of the most important of these influences was the French political philosopher Pierre-Joseph Proudhon whose words "Liberty is not the Daughter But the Mother of Order" appeared as a motto on "Liberty's" masthead" (influential individualist anarchist publication of Benjamin Tucker). "Another major foreign influence was the german philosopher Max Stirner". "The third foreign thinker with great impact was the British philosopher Herbert Spencer". Other influences to consider include William Godwin's "anarchism (which) exerted an ideological influence on some of this, but more so the socialism of Robert Owen and Charles Fourier.
