Man is the Religious Animal. He is the only Religious Animal. He is the only animal that has the True Religion, several of them. He is the only animal that loves his neighbor as himself, and cuts his throat if his theology isn't straight. He has made a graveyard of the globe in trying his honest best to smooth his brothers path to happiness and heaven...The higher animals have no religion. And we are told that they are going to be left out, in the Hereafter. I wonder why? It seems questionable taste.
Mark Twain, "The Lowest Animal"
