宋明帝。逸士顧歡作夷夏論。意黨道教。同徒袁粲為論以駁之。謂孔老教俗。釋氏出世。常侍何鎮之亦以書抵歡言。道家經籍簡陋。

Emperor Ming of the [Liu] Song: The recluse Gu Huan composed the *Treatise on the Barbarian and the Chinese*, intending to favor Daoism. His fellow companion Yuan Can wrote a treatise to refute it, stating that Confucius and Laozi taught secular matters while the Śākyan clan is world-transcending. Regular Attendant He Zhenzhi also addressed a letter to Huan, stating that the scriptures and records of the Daoist school are shallow and crude.
