Universal love, equal affection for all individuals, is a basic concept of the Mohist school of thought, as opposed to the principle of differentiated love advocated by the Confucian School. Universal love emphasizes that you should love others as you love yourself, and love others’ relatives and people of other states as you love your own so that all people would love one another equally. This principle of affection has no regard for blood ties or social status. It is an affection that is exercised equally without differentiating between individuals, families, or nations. If such a principle could be realized, we could avoid conflicts between persons, clans, or nations and bring equal benefit to all.
Universal love will bring peace and order to the world while mutual animosity can only throw the world into disorder. (Mozi)
