The lesson that human beings have learned in history is that they have not learned the lesson, which was said by the German philosopher Hegel.

it is not clear where Hegel said this. From a philosophical point of view, Hegel can be said to be a thorough historian. When talking about history, Hegel said: History often repeats itself astonishingly. To Hegel's famous saying, Marx added: The repetition of history is a tragedy for the first time and a comedy for the second time.

in Hegel's view, history is not a written record of a bunch of dead events, but a process of development to absolute spirit driven by the internal contradiction between subjective spirit and objective spirit. Therefore, history and logic are unified, and its manifestation is the internal negation process of negation of negation.

Hegel, for example, said that when a seed becomes a seedling, the seedling is a denial of the seed; However, the denial of seeds by seedlings contains the affirmation of seeds; Branches are the negation of seedlings, which also contains the affirmation of seedlings; Flowers are the negation of buds, and fruits are the negation of flowers.

Introduction to Hegel:

Georg Wilhelm Friedrich Hegel (German: Georg Wilhelm Friedrich Hegel, often abbreviated as G.W.F. Hegel; August 27th, 177-November 14th, 1831), a German philosopher.

Hegel, who was slightly later than Kant, was one of the representatives of German idealism philosophy in the 19th century. Hegel was born in Stuttgart, the capital of Baden-Wü rttemberg in southwest Germany today. He is the president of Berlin University (today's Humboldt University in Berlin).

Many people believe that Hegel's thoughts marked the peak of German idealistic philosophy movement in 19th century, and had a far-reaching influence on later philosophical schools, such as existentialism and historical materialism of Marx.

What's more, because Hegel's political thought has the essence of both liberalism and conservatism, his philosophy undoubtedly provides a new way out for those who feel that liberalism is facing challenges because they see that liberalism is powerless in recognizing personal needs and embodying human basic values.
