“"Man's inhumanity to man" is not the last word. The truth lies deeper. It is economic slavery, the savage struggle for a crumb, that has converted mankind into wolves and sheep.”

Context: But our great security lies, I think, in our growing strength, both in numbers and wealth; … unless, by a neglect of military discipline, we should lose all martial spirit …; for there is much truth in the Italian saying, Make yourselves sheep, and the wolves will eat you.

Blood Meridian (1985)
Source: Blood Meridian, or the Evening Redness in the West
Context: And the answer, said the judge. If God meant to interfere in the degeneracy of mankind would he not have done so by now? Wolves cull themselves, man. What other creature could? And is the race of man not more predacious yet? The way of the world is to bloom and to flower and die but in the affairs of men there is no waning and the noon of his expression signals the onset of night. His spirit is exhausted at the peak of its achievement. His meridian is at once his darkening and the evening of his day. He loves games? Let him play for stakes. This you see here, these ruins wondered at by tribes of savages, do you not think that this will be again? Aye. And again. With other people, with other sons.
