Voltaire (1694-1778) โ€“ How pitiful, and what poverty of mind, to have said that the animals are machines deprived of understanding and feeling . . . Judge (in the same way as you would judge your own) the behavior of a dog who has lost his master, who has searched for him in the road barking miserably, who has come back to the house restless and anxious, who has run upstairs and down, from room to room, and who has found the beloved master at last in his study, and then shown his joy by barks, bounds and caresses. There are some barbarians who will take this dog, that so greatly excels man in capacity for friendship, who will nail him to a table, and dissect him alive, in order to show you his veins and nerves. And what you then discover in him are all the same organs of sensation that you have in yourself. Answer me, mechanist, has Nature arranged all the springs of feeling in this animal to the end that he might not feel? Has he nerves that he may be incapable of suffering?
