Knowledge is in line with the direction of civilization, and it is the sum total of human exploration achievements in the material world and the spiritual world. So far, there is no unified and clear definition of knowledge. But the criterion for judging the value of knowledge lies in practicality, considering whether human beings can create new substances and gain strength and motivation.
The concept of knowledge is the most important concept in the field of philosophical epistemology. There is a classic definition from Plato: a statement can be called that knowledge must meet three conditions, and it must be verified, correct and believed by people. This is also the standard to distinguish between science and non-science.
From this perspective, knowledge belongs to culture, and culture is the sublimation of sensibility and knowledge, which is the relationship between knowledge and culture. The paradox about knowledge is that knowledge is useless if it can't change behavior; But once knowledge changes behavior, knowledge itself immediately loses its meaning-a brief history of the future.
