The whole world is taken up with serving him; the whole world toils for him. And in return this is the good he does for the world: he invents all the arts, all the tools, all the skills, all the instruments, all the crafts. He even teaches brute beasts arts denied them by Nature: ravens, jays, parrots and starlings he turns into poets; and magpies into poetesses, teaching them to talk, to sing and to utter human speech.
