"Ask a toad what beauty is, the to kalon? He will answer you that it is his toad wife with two great round eyes issuing from her little head, a wide, flat mouth, a yellow belly, a brown back. Interrogate a Guinea negro, for him beauty is a black oily skin, deep-set eyes, a flat nose. Interrogate the devil; he will tell you that beauty is a pair of horns, four claws and a tail. Consult, lastly, the philosophers, they will answer you with gibberish: they have to have something conforming to the arch-type of beauty in essence, to the to kalon."
