MOZI

Mozi was born around 470 BCE, probably in the state of Lu (Confucius’s homeland) or neighboring Song. Unlike Confucius, who came from fallen nobility, Mozi was likely an artisan — tradition makes him a carpenter. This shaped his philosophy: practical, egalitarian, impatient with aristocratic refinements.

He initially studied Confucianism, mastering its classics. But he came to reject it. Why should love be graded by relationship? Why spend resources on elaborate rituals and music when people starve? Why defer to hereditary privilege when rulers are incompetent? Confucianism, Mozi concluded, was the ideology of the aristocracy, serving their interests while disguising them as universal virtue.

His alternative was radical: jian ai, “impartial care” or “universal love.” Love your neighbor’s father as your own father, your neighbor’s state as your own state. If everyone did this, war would cease, theft would end, families would care for each other. The objection is obvious: people won’t do this. Mozi’s answer: they will if rulers model it and reward it. Ethics requires institutional support.

He founded a school more like a religious order than an academy. Mohists lived communally, dressed simply, shared property, and were bound by strict discipline. They developed expertise in defensive warfare and siege engineering — not to wage war but to prevent it. When a powerful state threatened a weaker one, Mohists would offer their services to the defender, making conquest too costly. Mozi himself reportedly walked ten days and nights to dissuade the state of Chu from attacking Song.

The school also developed logic, epistemology, and philosophy of language. Later Mohists (the “Dialecticians”) produced China’s most sophisticated logical and scientific thought, including optics, mechanics, and geometry. This systematic, argumentative approach distinguished Mohism from the more literary Confucian tradition.

For two centuries, Mohism rivaled Confucianism as China’s leading philosophy. Then it vanished. When the Han dynasty adopted Confucianism as state orthodoxy, Mohism was marginalized. Its texts survived but were barely read for nearly two thousand years. Only in the modern era has Mozi been rediscovered — and recognized as one of China’s most original thinkers.

Mozi’s philosophy begins with a question: what standard should guide action? His answer: benefit (li). An action is right if it benefits the people — increases population, wealth, and social order. This is consequentialism avant la lettre: judge by results, not intentions or traditions.

Applying this standard, Mozi examined Chinese society and found it failing. The cause? Partiality. People love their own families but not others’ families; their own states but not others’ states. From partiality flows theft (my benefit over yours), war (my state over yours), and family neglect (caring for mine, ignoring yours).

The solution is jian ai — impartial care. Treat others’ families as your own; others’ states as your own. This doesn’t mean identical emotional attachment but equal moral consideration. You may feel more affection for your own child, but you shouldn’t let another’s child starve to benefit yours.

How to implement this? Through rulers who model impartial care and reward it. Heaven itself, Mozi argued, cares for all equally — sending rain and sunshine without favoritism. Rulers should imitate Heaven. The state should promote impartiality through its systems of reward and punishment.

Mozi attacked Confucianism systematically. Graded love is partiality disguised as virtue. Elaborate funerals waste resources that could feed the hungry. Music distracts from useful work. Fatalism (“Heaven’s will”) excuses inaction. Even Confucian learning is problematic — studying poetry and ritual while ignoring practical benefit.

He was also a religious thinker. Heaven (Tian) has a will: it wants humans to care for each other impartially. Ghosts and spirits exist and punish wrongdoing. This religious dimension surprises modern readers expecting a secular utilitarian, but for Mozi, cosmic sanction strengthened ethical motivation.

Later Mohists developed the logical side. The Canons analyze language with precision: what does “knowing” mean? How do names refer to things? What makes an argument valid? They distinguished knowledge by testimony, by inference, and by direct experience. They explored paradoxes and defined geometrical terms. This tradition represented China’s closest approach to Greek-style logic — and was lost when Mohism declined.
