 Zongmi’s major philosophical work is Inquiry into the Origin of Humanity (Ch. Yuanren lun; T45.1886, trans. Gregory 1995). The title of this book might be a play on Inquiry into the Origin of the Way, an influential anti-Buddhist essay by the Confucian philosopher Han Yu (768–824). Zongmi’s book offers, in effect, an innovative panjiao system. The central innovation is its inclusion of Daoism and Confucianism. Zongmi’s discussion of the strengths and weaknesses of each view are detailed, and here we present only some of his arguments.
