Is Human Nature Tangible and Visible?——Dongpo Yizhuan's Criticism on the Traditional Theory of Human Nature

In Dongpo Yizhuan(lit.,SU Dongpo's Commentaries on the Yi),it believes that human nature is abstract and invisible.After Mencius started the tradition of explaining human nature with the good and the evil,scholars discussed the function of human nature instead of human nature itself.The theory in which human nature and Dao are put in the same theoretical level,reflects the thought of Lao-Zhuang school.SU Dong-po's theory of human nature has positive influence on us to comprehend the complicated problem of human nature,though his theory has been disproved by Neo-Confucianists such as ZHU Xi.
