Man can conquer nature by talking about the relationship between man and nature. This philosophical proposition is very rich in the history of China's ancient thoughts. Therefore, we must strictly distinguish between ancient thoughts and the slogan of human conquest of nature in the 20th century. In the eyes of our ancestors, nature is an organic whole, man is the epitome of the universe, and man and nature should achieve dialectical unity through interaction. Since 1950s, it has been popular in China that human beings can conquer nature, which means that human beings can certainly conquer nature. In dealing with the relationship between man and nature, this slogan has become a guiding concept and has had a wide impact for decades. I think it is necessary to reflect on history. From the ideological source, it is different from a series of related propositions in ancient China. Xunzi said that Liu Yuxi's human affairs are better than heaven, and heaven and people have different status. People should know what they do and what they don't do. Heaven and man have their own strengths, abilities and limitations. They are seeking truth from facts, and they are by no means conceited and take heaven as their enemy. The slogan we saw was taken out of context, and these necessary premises were abandoned. People are stronger than the sky (Yizhoushu), people are stronger than the sky (Wu Zixu), and people will conquer the sky (Xiangyang Song). Strength, abundance and stability are all conditions for people to win the day. The new slogan interprets the word "sure" as sure, that is, it completely abandons these necessary conditions. In particular, interpreting the word "victory" as "victory" falsifies the meanings of "superior" and "longer than" and completely puts nature in a hostile position. Whether intentionally or unintentionally, after the above castration and tampering, people in the 20th century have lost the original intention of history, become the slogan that human beings are arrogant and can do whatever they want, and naturally become an enemy who will eventually fail and can struggle, win and replace for a long time.
