《墨子·14章 兼爱(上)》
诸侯各自爱自己的国家，而不爱别的国家，所以攻打别国而使自己国家得利。天下各种乱事，全是这些了，细察它们的起因，都起于不相爱。
诸侯各爱其国，不爱异国，故攻异国以利其国，天下之乱物，具此而已矣。察此何自起？皆起不相爱。
Feudal lords each love their own state, and do not love other states; therefore they attack other states for the benefit of their own state. The world's many disorders all originate from this; examine them closely and they all stem from the lack of love.
