If a lover loves his body, it comes from Falling in Love by Mozi in the Warring States Period. If the whole world loves each other, if the lover loves his body, will there still be unfilial people? If you treat your father and brother as your own body, is it unfilial to do evil? Are there any unkind people? Is it inhuman to treat your disciples and ministers as yourself? Therefore, there is no filial piety and no compassion.

If the whole world loves each other, loving others is like loving yourself, can there be unfilial? How can you do unfilial things when you treat your father and brother as yourself? Is there anything unkind? How can you treat your son, brother and courtier as yourself? In this way, there will be no love.

Representative thought:

China's main thoughts of Mozi during the Warring States Period. Mozi regarded universal love as the core of his social ethics thought, and believed that the reason of social unrest at that time was that people could not love all. He advocated "being different" and opposed the Confucian view of "loving the poor". He put forward "love each other, mutual benefit", which linked fraternity with the equality and mutual benefit of people's material interests, showing the importance of utilitarianism.

Mozi's thoughts of Shang Xian, Shang Tong, frugality and non-aggression are all based on universal love, and he hopes to solve social contradictions by advocating universal love. Universal love is based on providence, which leads to the love, nurturing and tolerance of all things. The conclusion is that people should also love, nurture and tolerate everything.
