I have been scientifically studying the traits and dispositions of the "lower animals" (so-called,) and contrasting them with the traits and dispositions of man. I find the result profoundly humiliating to me. For it obliges me to renounce my allegiance to the Darwinian theory of the Ascent of Man from the Lower Animals; since it now seems plain to me that that theory ought to be vacated in favor of a new and truer one, this new and truer one to be named the Descent of Man from the Higher Animals.
Mark TwainThe moral sense enables one to perceive morality, and avoid it. The immoral sense enables one to perceive immorality and enjoy it.
Mark TwainWord it as softly as you please, the spirit of patriotism is the spirit of the dog and wolf. The moment there is a misunderstanding about a boundary line or a hamper of fish or some other squalid matter, see patriotism rise, and hear him split the universe with is war-whoop. The spirit of patriotism being in its nature jealous and selfish, is just in man's line, it comes natural to him - he can live up to all its requirements to the letter; but the spirit of Christianity is not in its entirety possible to him.
