 [The Song Confucians claimed that] with respect to heaven-and-earth, yin-yang cannot be called the dao; with respect to humanity, the physical endowment (qibing) cannot be called the nature (xing), and affairs and things of daily practicality in human relations cannot be called the Way (dao). There is nothing in the texts of the Six Classics, Confucius, and Mencius that agrees with them. (Dai MZZYSZ: 71–72)
