Beasts are rational (10)

ODYSSEUS. So now, Gryllus, you are transformed. Do you attribute reason even to the sheep and the ass?

GRYLLUS. From even these, dearest Odysseus, it is perfectly possible to gather that animals have a natural endowment of reason and intellect. For just as one tree is not more nor less inanimate than another, but they are all in the same state of insensibility, since none is endowed with soul, in the same way one animal would not be thought to be more sluggish or indocile mentally than another if they did not all possess reason and intellect to some degree - though some have a greater or less proportion than others. Please note that cases of dullness and stupidity in some animals are demonstrated by the cleverness and sharpness of others - as when you compare an ass and a sheep with a fox or a wolf or a bee. It is like comparing Polyphemus to you or that dunce Coroebus[*] to your grandfather Autolycus.[*] I scarcely believe that there is such a spread between one animal and another as there is between man and man in the matter of judgement and reasoning and memory.

ODYSSEUS. But consider, Gryllus: is it not a fearful piece of violence to grant reason to creatures that have no inherent knowledge of God?

GRYLLUS. Then shall we deny, Odysseus, that so wise and remarkable a man as you had Sisyphus for a father?[*]
