This is the Mohist idea.
Explanation of this sentence: Everyone in the world is upright, but I am dark and dirty. The Mohists advocate non-offensive-that is, they oppose aggressive wars (wars harm the loser, injuring lives and damaging others). It is a meaningless act of destruction. For the victor, it only gains several cities and taxes, but the overall damage and losses are huge, so the war is a meaningless act.) Love - that is, complete fraternity (extending the way of treating relatives such as father's kindness, son's filial piety, brothers and friends, brothers and sisters, etc. to other strangers, that is, all living beings.)
< p>Introduction to Mohism: Mohism was one of the major philosophical sects in China during the Eastern Zhou Dynasty. Together with the three major Han philosophical systems represented by Confucius (Confucianism) and Laozi (Taoism), Mohism formed a prosperous situation in which a hundred schools of thought contended. Mohism originated during the Warring States Period. The founder is Mo Zhai (Mozi). Mohism is a highly disciplined academic group, and its leader is called "Big Man". Its members must implement Mohist ideas when serving as officials in various countries, and their salaries must also be donated to the group. The Mohist school can be divided into early and late periods. The early thoughts mainly involved social politics, ethics and epistemology issues, and focused on the wars in the modern world. The later Mohists made important contributions in logic and began to move closer to the field of scientific research. It advocates equal love between people (universal love) and opposes aggressive war (non-aggression). Pay attention to cultural inheritance (Minggui) and grasp the laws of nature (Tianzhi).
