Xunzi

Xunzi (Chinese: 荀子; pinyin: Xúnzǐ; Wade–Giles: Hsün Tzu, ca. 312–230 BC) was a Chinese Confucian philosopher who lived during the Warring States Period and contributed to one of the Hundred Schools of Thought. Xunzi believed man's inborn tendencies need to be curbed through education and ritual, counter to Mencius's view that man is innately good. He believed that ethical norms had been invented to rectify mankind.
