The knowledge of the previous life always told Wang Xiaoli that science must exist as it already exists, and the steps are clear and you can’t make any mistakes. The same is true for human society. It is divided into several ladders and climbs up step by step. And with only this pair of ladders, it is impossible not to climb.

When you come to this world, you think you are the leader of the army. The more you think about it, the more you feel that there is something wrong with this statement. There is no way, and everything has to start from the original one. Only by explaining this principle clearly can you establish a solid political power.

Such a world is different from other worlds. Or it can be said that this is the world of Wang Xiaoli.

Historically, human society has never been the same. In the real world, human society is not the same. It is just a hypothesis to think that human society should be the same.

Clearing his throat, Wang Xiaolei said: "In human practice, we summarize and summarize, and add some imagination, people have compiled some knowledge about the regularity of nature and man. Some of the knowledge, because of its wide applicability, is relatively correct, and is called theory. These theories are very important, and are summarizing human past practices and prophecies of the future. Learning these theories to guide our practice is an important way to develop human society. However, just as the concepts were defined by humans, the same is true for theory. They are summarized by humans, not originally in the world. Such knowledge is different from Tao, and they are bound to be incorrect, but only an approximation to the real world."

Seeing the audience below one by one, they were stunned, obviously they had no idea what Wang Xiaolie was talking about. He was still sober, and he quickly took the pencil and remembered it quickly. It doesn’t matter if he didn’t understand it, as long as he wrote it down, he would slowly understand it.

"Theory is not naturally correct, so don't forget this. If you forget it, you think that what you have learned is the truth. If it doesn't match the facts, it must be that the facts are wrong. If they learn this way, there is really a problem. The theory is not really correct, and guiding practice must be inconsistent with reality. Therefore, the relationship between theory and practice is a big problem in work."

Many people think that there are too many things that take for granted by the humanities, and that natural science is rigorous. The theory of humanities is not necessarily correct, and the theory of natural science should not be doubted. In fact, it is not. Most scientists are very clear that the theories they learn are incomplete. It is just that under real conditions, this result can only be achieved. The work of scientists is largely a subversion of the theories of predecessors.

On the contrary, the theory of humanities is often suspected, while researchers in the humanities are very confident. They are confident that their theories are absolutely correct and denounce the doubters with ulterior motives.

To a certain extent, from the perspective of civilization, human beings have not yet come into contact with the truth. All theories, whether they are natural sciences, or humanities, are stage-by-stage. It is just a kind of understanding of the real world and an approximation. The development of science is to make this understanding deeper and this approximation closer to the real world.

When people live in the world, what we see, hear, touch, and feel is the real world. But summarizing and describing this real world to others will always have some deviations from the real world. These deviations are summarized into the theory, and the world described by the theory is different from the real world and is another aspect.

Many people cannot understand this difference, and even think that rigorous reasoning according to scientific theories is the real world. The past and future described by scientific laws are the reality of the world.

Actually not.

Humans have archaeology, genetic theory, and evolution, which depicts a map of human evolution. Some people believe this map and think that this is the truth of history. It can be said with certainty that this is not. This is just a certain stage of human understanding, based on these understandings of history. The development of science is to make this reasoning and imagination closer to reality, but not reality.

According to the laws of physics, humans have described the origin and development of the universe, and have predicted the future of the universe. Is this true? No. The Big Bang is just a hypothesis. Although it is convincing, it cannot be said that this is the truth of history.

This is the limitation of theory. When the theory starts, the initial knowledge is a kind of approximate understanding and description of the world by people. No matter what kind of reasoning is made, approximation cannot replace reality.

"If you know that theory is not truly correct, you should understand the relationship between theory and practice. If it is not truly correct, theory cannot truly guide practice. We use theory to guide it, either by borrowing from other people and other places, summarizing their practice, so that our practice has a roughly correct step. From this we can also know that practice is not the test and verification of theory, and practice is not the result of theoretical guidance. The process of practice is actually the correction of theory. When learning a theory, only after practice can it become our own theory. The theory and practice are inseparable. Without theory, practice is blind. Without practice, theory is incorrect."

"Theory of Practice" believes that there is truth, and truth can be discovered through practice. From perceptual knowledge to rational knowledge, it also guides practice from rational knowledge to transform the subjective and objective world. It is such a process, practice, cognition, practice, and cognition, and it is repeated to the endless. From the perspective of cognition, it is believed that there is truth, and the subsequent process actually has nothing to do with truth.

Wang Xiaoli didn't know if there was any truth, but at least he was at this stage, the truth did not exist. Practice was neither for discovering the truth nor for verifying the theory. Practice was human society itself. The so-called theory was just a summary of other people and other practices. Even if the theory was correct in other places, other people, and other things, the practice would be incorrect.

Looking at everyone, Wang Xiaoliu said: "When we do something, we should find relevant theories. Based on these theories, we will formulate plans for action. In the process of practice, we will inevitably find places that are inconsistent with the plan and places that are inconsistent with the theory. In this case, we should first check whether there are any mistakes and mistakes in the process of practice. If we eliminate the shortcomings of practice, we should doubt the theory and plan. We should avoid finding that the theory is inconsistent with the theory and not checking it. If we do not have a down-to-earth and prudent style and cannot carry out practical work seriously, it is a failed practice. For failed practice, it has nothing to do with whether the theory is correct. Eliminating the mistakes in practice, and the difference between the theory and the theory is the place where the theory should be modified."

In this era, people had no concept of theory or practice at all. Listening to Wang Xiaolie about these is like listening to a heavenly book. Some people who are used to it hurriedly write it down, for fear of remembering a word wrong.
