王弼
He Yan believed that Daoism and Confucianism complimented each other so that by studying them both in a correct manner a scholar could arrive at a single, unified truth. Arguing for the ultimate compatibility of Daoist and Confucian teachings, He argued that "Laozi [in fact] was in agreement with the Sage" (sic). By promoting the synthesis of Daoist and Confucian concepts, He became a principal advocate of the neo-Daoist school of Xuanxue (along with his friend and contemporary, Wang Bi). As a scholar of Xuanxue, He was notable for exploring the theory of wuwei. He was a prolific writer of poetry and wrote numerous miscellaneous essays on philosophy, politics, literature, and history, some of which still survive.
