'Once more, sage sovereigns cease to arise, and the princes of the States give the reins to their lusts. Unemployed scholars indulge in unreasonable discussions. The words of Yang Chû and Mo Tî fill the country. If you listen to people's discourses throughout it, you will find that they have adopted the views either of Yang or of Mo. Now, Yang's principle is "each one for himself," which does not acknowledge the claims of the sovereign. Mo's principle is "to love all equally," which does not acknowledge the peculiar affection due to a father. But to acknowledge neither king nor father is to be in the state of a beast.Go here to read the introductory post to this serialized version of the Works of Mencius.
Kung-ming Î said, "In their kitchens, there is fat meat. In their stables, there are fat horses. But their people have the look of hunger, and on the wilds there are those who have died of famine. This is leading on beasts to devour men." If the principles of Yang and Mo be not stopped, and the principles of Confucius not set forth, then those perverse speakings will delude the people, and stop up the path of benevolence and righteousness. When benevolence and righteousness are stopped up, beasts will be led on to devour men, and men will devour one another.
'I am alarmed by these things, and address myself to the defense of the doctrines of the former sages, and to oppose Yang and Mo. I drive away their licentious expressions, so that such perverse speakers may not be able to show themselves. Their delusions spring up in men's minds, and do injury to their practice of affairs. Shown in their practice of affairs, they are pernicious to their government. When sages shall rise up again, they will not change my words.
