Many people quote Hegel's famous saying that everything that exists is reasonable to get rid of their worries about things that cannot be explained and things that are unacceptable. Just like talking about rare confusion, people who don't want to know much often use Hegel's sentence as a shield to escape from reality and contradiction. The popularity of this sentence in China is too high, much higher than Big Logic and Little Logic, and even higher than Hegel himself. It is estimated that Hegel, who knows everything from the spring, will be very puzzled that he said so much, and only this sentence is so popular in China.

Hegel's "rationality" or "rationality" means that since it exists, there must be a reason for its existence. There is absolutely no meaning of "correctness" here, let alone "rationality", so it cannot be questioned, opposed or changed. The major misunderstanding here lies in the ambiguity of the word "reasonable" in China, which contains the logic that "reasonable equals reasonable, reasonable equals correct equals unchangeable".

the reason why history is enduring is that every step of human society's progress has been made by re-examining and evaluating the past history. However, a more thorough reflection on history will often encounter strong opposition and resistance. Resistance comes from the fear of vested interests, and more from the limitations and misunderstandings of understanding. One of the powerful weapons against the resisters is Hegel's sentence. Since everything that exists is reasonable, why are you still whispering? You are quite justified. Here, the opponents intentionally or unintentionally confuse the rationality of history with the rationality of value.

the so-called historical rationality refers to the objectivity of history, including the cause, process and end of a historical event. To explore the rationality of history is to explore and study the motivation, mechanism and change context behind the emergence of historical events, just like the study of natural phenomena; The rationality of value refers to people's subjective understanding, including the evaluation of historical events. For a specific historical event, whether it is reasonable or unreasonable in value is based on the subjective will of the appraiser. Therefore, for the same historical event, the evaluations of many evaluators are often quite different. Of course, the evaluation of most people's consistency must reflect the mainstream consciousness in this particular historical stage of society.

interestingly, the distinctive evaluation of the same historical event or character will not only occur between different evaluators in the same generation, but also between different eras. Times have changed, people's values have changed, and idolatry in the past may become contemptible garbage. For example, in the past, many people believed that "a winner defeats a thief", and as long as things are done, it is considered reasonable to resort to three kinds of abuse. Now people understand "procedural justice" and begin to disapprove of "by all means".

As long as we carefully observe and summarize, we can find that re-evaluation of past history is often a harbinger of social change and progress, which shows that the mainstream social consciousness with values as the core has changed. This development and change of value rationality will certainly create a new and better history for mankind.
