Zhou Dunyi
Despite Confucianism losing popularity to Taoism and Buddhism, Neo-Confucianism combined those ideas into a more metaphysical framework. Its concepts include "li" (principle, akin to Plato's forms), "qi" (vital or material force), "tai-chi" (the Great Ultimate), and "xin" (mind). Song dynasty philosopher Zhou Dunyi (1017–1073) is seen commonly seen as the first true "pioneer" of Neo-Confucianism, using Daoist metaphysics as a framework for his ethical philosophy. Neo-Confucianism developed both as a renaissance of traditional Confucian ideas, and as a reaction to the ideas of Buddhism and religious Daoism. Although the Neo-Confucianists denounced Buddhist metaphysics, Neo-Confucianism did borrow Daoist and Buddhist terminology and concepts.
