"To one whose mind is free, there is something even more intolerable in the suffering of animals than in the sufferings of men. For with the latter it is at least admitted that suffering is evil and that the man who causes it is a criminal. But thousands of animals are uselessly butchered every day without a shadow of remorse. If any man were to refer to it, he would be thought ridiculous. And that is the unpardonable crime. That alone is the justification of all that men may suffer. It cries vengeance upon all the human race. If God exists and tolerates it, it cries vengeance upon God."
-Romain Rolland (Nobel Laureate), Jean Christophe
