|He who is cruel to animals becomes hard also in his dealings with men. We can judge the heart of a man by his treatment of animals.
– Immanuel Kant (1724-1804)
|People speak sometimes about the “bestial” cruelty of man, but that is terribly unjust and offensive to beasts, no animal could ever be so cruel as a man, so artfully, so artistically cruel.
– Fyodor Dostoevsky (1821-1881)
|Of all the animals, man is the only one that is cruel. He is the only one that inflicts pain for the pleasure of doing it.
– Mark Twain (1835-1910)
