Whatever you do, trample down abuses, and love those who love you. Different translation: Whatever you do, crush the infamous thing superstition, and love those who love you.
VoltairePeople must have renounced, it seems to me, all natural intelligence to dare to advance that animals are but animated machines.... It appears to me, besides, that such people can never have observed with attention the character of animals, not to have distinguished among them the different voices of need, of suffering, of joy, of pain, of love, of anger, and of all their affections. It would be very strange that they should express so well what they could not feel.
