What is Mozi?
Mozi (墨子, c. 470–391 BCE) was a Chinese philosopher of the Warring States period and the founder of Mohism (Mòjiā, 墨家). His central teaching was jiān ài, usually translated as universal love or impartial caring. He argued that every person deserves the same moral consideration, regardless of their relationship to you. Mohism was one of the Hundred Schools of Thought that competed for influence in ancient China before the Qin dynasty unified the country in 221 BCE. His ideas survive in the text also called the Mozi, compiled by his followers after his death. The exact dates of his life are uncertain; scholars place his birth around 470 BCE and his death around 391 BCE.
Mozi vs Confucius and the Taoists
The sharpest contrast is with Confucius (c. 551–479 BCE), whose teaching centred on rén (benevolence) extending outward from family relationships. Confucius held that it is natural and right to care more for one's own family than for strangers. Mozi rejected this directly. He called graduated love the root cause of conflict between families and states. Both philosophers argued from moral principle and drew opposite conclusions. Against the Taoists, the contrast is different. Lao Tzu and Zhuangzi counselled [wu-wei](lexicon:wu-wei), effortless non-action that moves with the grain of nature. Mozi was an activist. He and his followers travelled between states arguing against wars of aggression and reportedly helped defend cities under siege by training engineers in fortification. Where the Taoists sought harmony through withdrawal from artificial social structures, Mozi sought it through organised collective effort.
Mozi's core teachings
Mozi's programme rests on several linked claims. Universal love (jiān ài) is the foundation. He argued that if everyone treated other families as their own and other states as their own, wars and theft would cease. His opposition to offensive warfare followed from this. He considered aggressive war a moral wrong on the same level as murder or theft, but worse in scale. He also argued for frugality in government and in funerary practice. Elaborate state ceremonies, music, and extended mourning were, in his view, a waste of resources that could otherwise feed the hungry. He argued that rulers should appoint officials on the basis of ability rather than birth.
The Mozi text also contains the Mo Jing (墨經), a set of propositions on logic, optics, and mechanics. Historians of Chinese science regard these chapters as among the earliest systematic statements of formal reasoning in China. They discuss the structure of valid argument, the physics of levers and pulleys, and the optics of light and shadow. Scholars debate how much of this material reflects Mozi himself versus later Mohist disciples; the Mo Jing is generally thought to postdate Mozi by several generations.
Decline and later attention
After the Qin unification in 221 BCE, Mohism dissolved as an organised school. The Han dynasty established Confucianism as state orthodoxy, and Mohist networks did not survive. For roughly two thousand years Mohism was preserved in texts but had no active institutional presence.
Modern interest revived in the nineteenth and twentieth centuries. Chinese reformers recognised that Mozi's emphasis on universal concern, practical utility, and opposition to hereditary privilege offered different resources from the Confucian tradition. Comparative philosophers have noted parallels with Jainism, another tradition of the fifth century BCE built around non-violence ([ahimsa](lexicon:ahimsa)) and equal concern for all beings. The parallel with Buddhist metta (loving-kindness) is also drawn, though the metaphysical frameworks differ. These comparisons are descriptive. No historical connection between Mozi and the Indian traditions has been established.
Mozi in this index
No items in the index currently cover Mohism or Mozi directly. The topic appears in comparative philosophy discussions rather than in contemporary spiritual teaching. Entries on ahimsa, jainism, taoism, and wu-wei touch adjacent territory from the Indian and Chinese traditions. This entry exists to name the concept precisely and to anchor the cross-references when relevant media enters the index.
