1724 – 1777
Dai Zhen (戴震, 1724–1777) was a Qing dynasty Chinese philosopher, philologist, and mathematician, widely regarded as the most rigorous critic of Song-Ming Neo-Confucianism. Working within the kaozheng (evidential scholarship) tradition, he argued that Neo-Confucian li (principle) had been weaponized to suppress natural human desires and emotions, which he held to be morally legitimate expressions of human nature. His Mengzi ziyi shuzheng subjected the Mencian text to systematic philological analysis to recover what he saw as authentic Confucian ethics against later metaphysical distortions.
