What is the purpose of houses? It is to protect us from the wind and cold of winter, the heat and rain of summer, and to keep out robbers and thieves. Once these ends have been secured, that is all. Whatever does not contribute to these ends should be eliminated.

The murder of one person is called unrighteous and incurs one death penalty. Following this argument, the murder of ten persons will be ten times as unrighteous and there should be ten death penalties; the murder of a hundred persons will be a hundred times as unrighteous and there should be a hundred death penalties. All the gentlemen of the world know that they should condemn these things, calling them unrighteous. But when it comes to the great unrighteousness of attacking states, they do not know that they should condemn it. On the contrary, they applaud it, calling it righteous.

Universal love is really the way of the sage-kings. It is what gives peace to the rulers and sustenance to the people. The gentleman would do well to understand and practise universal love; then he would be gracious as a ruler, loyal as a minister, affectionate as a father, filial as a son, courteous as an elder brother, and respectful as a younger brother. So, if the gentleman desires to be a gracious ruler, a loyal minister, an affectionate father, a filial son, a courteous elder brother, and a respectful younger brother, universal love must be practised. It is the way of the sage-kings and the great blessing of the people.

Now, as to universal love and mutual aid, they are beneficial and easy beyond a doubt. It seems to me that the only trouble is that there is no superior who encourages it. If there is a superior who encourages it, promoting it with rewards and commendations, threatening its reverse with punishments, I feel people will tend toward universal love and mutual aid like fire tending upward and water downwards - it will be unpreventable in the world.

When we try to develop and procure benefits for the world with universal love as our standard, then attentive ears and keen eyes will respond in service to one another, then limbs will be strengthened to work for one another, and those who know the Tao will untiringly instruct others. Thus the old and those who have neither wife nor children will have the support and supply to spend their old age with, and the young and weak and orphans will have the care and admonition to grow up in. When universal love is adopted as the standard, then such are the consequent benefits. It is incomprehensible, then, why people should object to universal love when they hear it.

When we come to think about the several benefits in regard to their cause, how have they arisen? Have they arisen out of hate of others and injuring others? Of course we should say no. We should say they have arisen out of love of others and benefiting others. If we should classify one by one all those who love others and benefit others, should we find them to be partial or universal? Of course we should say they are universal. Now, since universal love is the cause of the major benefits in the world, therefore Mozi proclaims universal love is right. And, as has already been said, the interest of the magnanimous lies in procuring benefits for the world and eliminating its calamities. Now that we have found out the consequences of universal love to be the major benefits of the world and the consequences of partiality to be the major calamities in the world; this is the reason why Mozi said partiality is wrong and universality is right.

Whoever criticizes others must have something to replace them. Criticism without suggestion is like trying to stop flood with flood and put out fire with fire. It will surely be without worth.

If we should classify one by one all those who hate others and injure others, should we find them to be universal in love or partial? Of course we should say they are partial. Now, since partiality against one another is the cause of the major calamities in the empire, then partiality is wrong.

If the rulers sincerely desire the empire to be wealthy and dislike to have it poor, desire to have it orderly and dislike to have it chaotic, they should bring about universal love and mutual aid. This is the way of the sage-kings and the way to order for the world, and it should not be neglected.

When feudal lords love one another there will be no more war; when heads of houses love one another there will be no more mutual usurpation; when individuals love one another there will be no more mutual injury. When ruler and ruled love each other they will be gracious and loyal; when father and son love each other they will be affectionate and filial; when older and younger brothers love each other they will be harmonious. When all the people in the world love one another, then the strong will not overpower the weak, the many will not oppress the few, the wealthy will not mock the poor, the honoured will not disdain the humble, and the cunning will not deceive the simple. And it is all due to mutual love that calamities, strife, complaints, and hatred are prevented from arising. Therefore the benevolent exalt it.
