“I do not believe any animal is capable of being cruel. Cruelty implies consciousness of another’s pain and the intent to cause it. Cruelty is a human specialty, which human beings continue to practice, and perfect, and institutionalize, though we seldom boast about it. We prefer to disown it, calling it ‘inhumanity,’ ascribing it to animals. We don’t want to admit the innocence of the animals, which reveals our guilt.”
