…Stevens himself hating horses even more than dogs, rating the horse an unassailable first in loathing since though both were parasites, the dog at least had the grace to be a sycophant too; it at least fawned on you and so kept you healthily ashamed of the human race. But the real reason was, though neither the horse nor the dog ever forgot anything, the dog at least forgave you; and his, Stevens's, thought was that what the world needed was more forgiving.
