"Unity of knowledge and action" comes from the Theory of Practice written by Wang Yangming, a thinker in the Ming Dynasty, which implies a high degree of unity of thought and action.
"Stop at perfection" comes from Book of Rites University. Original: The way of a university is to be virtuous, to be close to the people, and to stop at perfection.
Translation of vernacular Chinese: The purpose of a university is to carry forward the aboveboard moral character, make people abandon the old and establish the new, and make people reach the most perfect state.
Expand the background of the integration of knowledge and practice of data;
After Wang Yangming was enlightened in Longchang Town, xiuwen county, north of Guiyang, he deeply realized the truth of life, which was an epiphany after hard thinking. Wang Yangming believes that mentality determines behavior and world outlook, such as the story of Liezi's "suspicious neighbor stealing axe". From then on, he parted ways with Zhu Xuexue, which laid the foundation for the great success of the system of psychology.
Wang Shouren's theory of the unity of knowing and doing is mainly aimed at Zhu's study, which is contrary to Zhu's thought. Oppose Zhu Cheng's Neo-Confucianism's theory of "dichotomy of knowing and doing, thinking that you must be a prophet and then you can do it" and the resulting style of study of "valuing knowledge but neglecting action".
Zhu Cheng Neo-Confucianism, including Lu Jiuyuan, advocates "knowing after the prophet", divides knowledge into two parts, and holds that knowledge must be known before it can be practiced. Wang Shouren advocated the unity of knowledge and action to correct Zhu Xue's bias.
