As far as civilization is concerned, the geographical discovery is actually a great discovery of "civilization", or more accurately, a great discovery of European civilization. In the process of discovering a large number of backward nationalities around the world, Europeans have established a new imagination of the humanistic world. Edward said studied the "imaginary geography and history" in "Culture and Imperialism", which is often reflected in the stories told by colonial explorers and the works of novelists, and pointed out that these imaginations will strengthen their feelings about themselves by exaggerating the differences between native and distant regions. Although Europeans have gone through hardships in the rough sea, the achievements of these "discoveries" and their new imagination of the human world make them feel how good they are to stand out from the crowd. On the contrary, "it also became a way for colonial people to confirm their identity and existence."

The colonial people proved their barbarity and backwardness in front of the mighty European ships. As a result, a new world history was opened and a new nation-state relationship was established. Although the distinction between civilization and savagery is not a new concept consciousness, in ancient China and Rome, the concepts of "the distinction between China and foreigners" and "the distinction between literati and savages" were very popular. But at this time, the distinction between civilization and barbarism and the field of classical literature have completely different connotations and conclusions. In the controversy of classical literature, the civilized side basically demands nothing from the savage side except "keeping away from the crowd" and "border security", and hopes to permanently restrict its communication with the Great Wall. At this time, the civilized side will invade, rule and deprive the savage side.

Marx and Engels pointedly pointed out from the economic point of view in the Declaration of * * *: "The bourgeoisie has brought all ethnic groups, even the most barbaric ethnic groups, into civilization because of the rapid improvement of all means of production and the extremely convenient transportation. Its commodity price is low, and it is a heavy artillery used to destroy the Great Wall and conquer the most tenacious xenophobia of these barbarians. It forces all ethnic groups-if they don't want to perish-to adopt the bourgeois mode of production; It forces them to carry out the so-called civilized system in their own places, that is, to become the bourgeoisie. In short, it created a world for itself according to its own appearance. "

Colonization reflects the contrast between colonial countries and colonized countries and regions. Most immigrants from colonial countries enjoy superior political rights in colonies than local residents and have obvious racial and ethnic discrimination. This has done great harm to the personality and dignity of indigenous people.

The religion, culture, economy and productivity of a colony are generally greatly improved under the influence of colonization, which often becomes an excuse for colonists to show their dignity. They pretended to be saviors by bringing civilization, advanced culture and advanced tools to the colonies, so as to cover up the nature of their aggression, plunder, exploitation and oppression and their wrong foothold. This is typical robber logic. In this sense, the colonial people will not appreciate it. Once the people's democratic consciousness awakens and their national consciousness intensifies, the struggle for colonial independence becomes more and more acute, and the colonial pattern and achievements, as well as life and property, are even destroyed by extreme practices, causing huge losses.
