Mozi
Mohist · East Asia · 470 to 391 BCE
Chinese thinker who taught impartial care for all people and judged customs by whether they benefit everyone.
What it is
Mozi, or Mo Di, was a Chinese thinker who lived in the late fifth century BCE, in the Warring States era, and founded the movement called Mohism. He is remembered as the first major intellectual rival of Confucius and his followers, and as one who, like Socrates, searched openly for objective standards of right and wrong and argued for them step by step.
He is best known for his doctrine of impartial concern, often called universal love: that one should care for the welfare of all people equally, without favouring one's own family or associates. His teaching is summed up in ten theses, argued in the book that bears his name, though he is unlikely to have written it himself.
The main ideas
- Impartial concern. People should care for others without drawing a line between self and other, or between family and strangers. This replaces the Confucian emphasis on special concern for one's own relatives.
- Benefit as the test. The right thing to do is whatever benefits the people, and customs and rituals are to be judged by whether they do. It is among the earliest forms of consequentialism.
- Against war and waste. He opposed aggressive war, extravagant funerals and lavish music, which waste resources that could feed and clothe the common people.
- Rewarding the worthy. Offices should go to the able and the worthy, and not to those of high birth.
- Heaven and spirits. He taught that Heaven wants people to care for each other, and that spirits reward the good and punish the wicked, and he rejected fatalism, the idea that our lot is fixed whatever we do.
What it looks like in practice
Picture someone on a town council deciding how to spend a limited budget, tempted to favour their own district. Mozi would ask them to weigh every person's need equally, and to count the cost of a grand ceremony in meals not served. This is an illustration of the idea, not a quotation.
Books and moments
- The Mozi is the book of the ten theses, compiled by his followers.
- The community he founded was quasi-religious and paramilitary, and used expertise in defensive warfare to help small states under threat.
- The later Mohist texts on logic and argument are among the earliest in China.
Questions and criticism
- Can anyone care equally for everyone? Confucians replied that this ignores the natural strength of family bonds, and the question is still argued.
- Is benefit a sound standard? Because the test is so simple, it is asked whether it can account for rights, fairness and special obligations.
- Why does Heaven's will matter? His appeal to Heaven and spirits can look like a cover for a practical programme, and readers ask how far the religion is essential to it.

He argued against Confucius's school, and Confucian thinkers replied. The pages on Confucius and Mencius show the other side of the debate.
