Dai Zhen

Dai Zhen, courtesy name Shenxiu (慎修), art name Dongyuan (東原), was a Chinese philosopher of the Qing dynasty. Hailing from Xiuning, Anhui Dai was a versatile scholar who made great contributions to mathematics, geography, phonology and philosophy. His philosophical and philological critiques of Neo-Confucianism continue to be influential. In 1733, Dai was recruited by scholar Ji Yun to be one of the editors of the official encyclopedia and collection of books, Siku Quanshu.
