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).
Elizabeth Costello
Elizabeth Costello frequently engages philosophers and their ideas. Among the philosophers mentioned by name are historical figures such as Aristotle, Porphyry, Augustine, Thomas Aquinas, René Descartes and Jeremy Bentham, as well as contemporary figures such as Mary Midgley, Tom Regan and Thomas Nagel. In addition two minor characters, Elaine Marx and an academic named Arendt (whose first name is not mentioned) share surnames with the famous philosophers Karl Marx and Hannah Arendt. The frequent allusions to philosophers have caused critics to debate whether there are philosophical themes in Coetzee’s work and, if so, what they might be.
