The atheists are for the most part imprudent and misguided scholars who reason badly who, not being able to understand the Creation, the origin of evil, and other difficulties, have recourse to the hypothesis the eternity of things and of inevitability.
VoltaireAnswer me, you who believe that animals are only machines. Has nature arranged for this animal to have all the machinery of feelings only in order for it not to have any at all?
VoltaireWe are going to a new world... and no doubt it is there that everything is for the best; for it must be admitted that one might lament a little over the physical and moral happenings of our own world.
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.
