The meaning of understanding things is to explore the principles of things, so as to gain wisdom from them (or infer the principles and laws of things and sum them up as rational knowledge).
Source: The Book of Rites by Dai Sheng in the Western Han Dynasty? If you want to be sincere, you should know it first; Knowledge lies in things. The content is then known, and the knowledge is then sincere. It means that if you want to make your thoughts sincere, you must first acquire knowledge; The way to acquire knowledge is to know and study everything. Knowledge can only be obtained through the understanding and research of everything; Only after acquiring knowledge can the mind be sincere.
the relationship between knowledge and knowledge:
1. The purpose of knowledge is to learn from knowledge, and knowledge cannot be separated from it. First of all, it is for the purpose of understanding things, which is an experiential and fragmentary way of perceiving things directly, while knowing things is for induction and sublimation after getting enough knowledge, which is quantitative change, qualitative change, quantitative change and qualitative change.
2. Knowledge is also inseparable from things. Zhu Xi believes that although reason is contained in people's hearts, people can't directly perceive it. It is still necessary to contact specific things to present the difference of things. Only when the poor reason reaches the extreme can we achieve the connection between things and me and truly understand and obtain it. Gewu is quantitative change, and knowledge is qualitative change. The occurrence of qualitative change cannot be separated from the accumulation of quantitative change, so knowledge cannot be separated from Gewu.
3. Knowing is the natural result after the process of learning things. Gewu refers to the investigation of things to exhaust the reason of things, and when people exhaust the reason of things, people's knowledge will be completely complete, so knowing is the natural result after the process of Gewu. Therefore, Gewu and Zhizhi are integrated and two sides of the same thing. Gewu is concrete and inductive, while Gewu is abstract and practical.
Therefore, the relationship between the object and the knowledge is actually unified with each other, and they are both indispensable and complementary. Being realistic and knowing are two different ways of discussing the same thing, not two different efforts.
