As a Confucian argument integral to the concept of "The Destiny as the Provenance of Human Nature" and Xun Zi's doctrine, "the art of the mind" is philosophically structured around the concepts of nature, emotion and mind, involving the orientations of the doctrine of human nature. Whether approached from the doctrine of nature or the doctrine of human nature, the objectivity of emotion and the orientation of mind, or even the practice of the self-cultivation of justice, according to the analysis of this article, although both "The Destiny as the Provenance of Human Nature" and Xun Zi's doctrine show how pre-Qin Confucians speculated about nature, emotion and mind as the elements of humanism and deontology, in the Guo-Dian Bamboo Slips, the discourse on "nature" connotes the mandate of heaven, "mind" and "emotion" are valuable, and the teaching and learning of justice are oriented toward the enlightenment of The Book of Odes, The Book of Documents, The Records of Rites and The Book of Music, while in Xun Zi's thought, with his distinction between heaven and man, there is no concept of the heavenly way, the theories of "nature" and "emotion" are not valuable, and the doctrine of "mind" refers to knowing the truth rather than the foundation of morality. While also stressing justice in his doctrine on education, Xun Zi indeed focused on the cultivation of moral norms. Therefore, in terms of philosophical veins, "The Destiny as the Provenance of Human Nature" is quite different from Xun Zi's idea of "the art of the mind."
