Thought experiment. Two tribes, the northern herders and the southern herders. The northern herders, the collectivists, agree to live according to the common good, such that no man would starve in time of plenty. The southern herders, the individualists, agree to live according to individual rights. A man may go hungry in the south, but all community action is voluntary on principle. Is there any sensible way in which one tribe can be called more moral than the other? Is there some metamorality by which we can make sense of this?
"In the beginning of human life, when there was yet no law and government, the custom was "everybody according to his moral (yi)." Accordingly each man had his own moral, two men had two different morals and ten men had ten different morals -- the more people the more different notions. And everybody approved of his own moral and disapproved the views of others, and so arose mutual disapproval among men. As a result, father and son and elder and younger brothers became enemies and were estranged from each other, since they were unable to reach any agreement. Everybody worked for the disadvantage of the others with water, fire, and poison. Surplus energy was not spent for mutual aid; surplus goods were allowed to rot without sharing; excellent teachings (Dao) were kept secret and not revealed."
