What do you mean by the unity of virtue, kindness, knowledge and action?

"Virtue, knowing and doing are one" is two words, which means: to carry forward the aboveboard moral character is to make people abandon the old and seek the new, and to make people reach the most perfect state. Understanding the truth of the matter and carrying it out are inseparable.

The sentence "Mingde Shan Zhi" comes from the beginning of "University": "The way of a university is to be famous and close to the people, and stop at perfection." It means that the purpose of the university is to carry forward the aboveboard moral character, make people innovate and reach the most perfect state.

"Unity of knowledge and action" was put forward by Wang Shouren, a thinker in Ming Dynasty, that is, the truth of knowing things and the truth of executing things are inseparable. Knowledge refers to inner awareness, understanding of things, and behavior refers to people's actual behavior. The unity of knowledge and action is not to swallow action with knowledge, nor to swallow action with action, but to think that action is knowledge, with conscience inside and good deeds outside. If there is no conscience, there will be no actual charity. It is an epistemological and practical proposition in China's ancient philosophy, mainly about cognitive practice.
