From Human Nature and Conduct:
We are forced therefore to consider the nature and origin of that control of human nature with which morals has been occupied. And the fact which is forced upon us when we raise this question is the existence of classes. Control has been vested in an oligarchy. Indifference to regulation has grown in the gap which separates the ruled from the rulers. Parents, priests, chiefs, social censors have supplied aims, aims which were foreign to those upon whom they were imposed, to the young, laymen, ordinary folk; a few have given and administered rule, and the mass have in a passable fashion and with reluctance obeyed. Everybody knows that good children are those who make as little trouble as possible for their elders, and since most of them cause a good deal of annoyance they must be naughty by nature. Generally speaking, good people have been those who did what they were told to do, and lack of eager compliance is a sign of something wrong in their nature.
But no matter how much men in authority have turned moral rules into an agency of class supremacy, any theory which attributes the origin of rule to deliberate design is false. To take advantage of conditions after they have come into existence is one thing; to create them for the sake of an advantage to accrue is quite another thing. We must go back to the bare fact of social division into superior and inferior.
