Discourses: Book 3 14 : 5
"I am superior to you, for my father has consular rank." Another says, "I have been a tribune, and you have not." And if we were horses, you would be saying: "My sire was swifter than yours," or, "I have quantities of barley and fodder," or, "I have pretty neck-trappings." What then, if, when you were talking like this, I said, "Granted all that, let's run a race, then"? Come now, is there, then, nothing in man like running in the case of a horse, whereby the worse and the better will be recognized? Isn't there such a thing as reverence, faith, justice? Prove yourself superior in these points, in order to be superior as a human being. If you tell me, "I can deliver a mighty kick," I shall say to you in my turn, "You are proud over what is the act of an ass."
