What makes a dog beautiful makes a horse ugly. What makes a horse beautiful makes a dog ugly. That's because their natures are different. Look at athletes. What makes a fighter beautiful makes a wrestler look bad and a runner look ridiculous. Someone who's perfect for the pentathlon looks terrible at wrestling. So what makes a human beautiful? The same principle that makes dogs and horses beautiful in their own way. What makes a dog beautiful? Having the excellence of a dog. What makes a horse beautiful? Having the excellence of a horse.

That then which makes a dog beautiful, makes a horse ugly; and that which makes a horse beautiful, makes a dog ugly, if it is true that their natures are different. It seems to be so.

It is so, said he. What then makes a man beautiful? Is it that which in its kind makes both a dog and a horse beautiful? It is, he said. What then makes a dog beautiful? The possession of the excellence of a dog. And what makes a horse beautiful? The possession of the excellence of a horse. What then makes a man beautiful? Is it not the possession of the excellence of a man?
