brief Introduction of the content
University and the Doctrine of the Mean are two in The Book of Rites. "University" takes human cultivation as the core and puts forward: "From Tian Zi to Shu Ren, cultivation is the foundation." The way to cultivate one's morality is to be realistic, harmonious, sincere and upright. Emphasizing human cultivation is not only a process of introspection, but also a process of contacting foreign objects, learning physics to acquire knowledge, cultivating moral character and perfecting personality. The purpose of self-cultivation is to manage the family, govern the country and level the world. "University" believes that the rule of the country and the world should be based on morality. The doctrine of the mean emphasizes "sincerity" and holds that "sincerity" is the key to realize the doctrine of the mean. The Doctrine of the Mean is an important Confucian classic, which, like the Book of Changes, is the theoretical source of Confucianism. However, the Book of Changes has a greater influence and a wider scope than the Doctrine of the Mean, which is the focus of Confucian studies after the Song Dynasty. Many concepts and propositions of Confucianism, especially Neo-Confucianism, come from the doctrine of the mean. Many neo-Confucians adhere to the doctrine of the mean, and many Confucians think with the methodology of the mean, which shows that the mean has a far-reaching influence on the formation of Chinese civilization.
