" Satan was not disturbed, but I could not endure it, and had to be whisked out of there. I was faint and sick, but the fresh air revived me, and we walked toward my home. I said it was a brutal thing. "No, it was a human thing. You should not insult the brutes by such a misuse of that word; they have not deserved it," and he went on talking like that. "It is like your paltry race—always lying, always claiming virtues which it hasn't got, always denying them to the higher animals, which alone possess them. No brute ever does a cruel thing—that is the monopoly of those with the Moral Sense. When a brute inflicts pain he does it innocently; it is not wrong; for him there is no such thing as wrong. And he does not inflict pain for the pleasure of inflicting it—only man does that. Inspired by that mongrel Moral Sense of his! "
