Without the doctrine of the Fall all idea of progress is unmeaning. [Some] say that there was not a Fall but a gradual rise. But the very word "rise" implies that you know toward what you are rising. Unless there is a standard you cannot tell whether you are rising or falling. But the main point is that the Fall like every other large path of Christianity is embodied in the common language talked on the top of an omnibus. Anybody might say, "Very few men are really Manly." Nobody would say, "Very few whales are really whaley."
If you wanted to dissuade a man from drinking his tenth whisky you would slap him on the back and say, "Be a man." No one who wished to dissuade a crocodile from eating his tenth explorer would slap it on the back and say, "Be a crocodile." For we have no notion of a perfect crocodile; no [record] of a whale expelled from his whaley Eden. If a whale came up to us and said: "I am a new kind of whale; I have abandoned whalebone," we should not trouble. But if a man came up to us...to say, "I am a new kind of man. I am the super-man. I have abandoned mercy and justice"; we should answer, "Doubtless you are new, but you are not nearer to the perfect man, for he has been already in the mind of God. We have fallen with Adam and we shall rise with Christ; but we would rather fall with Satan than rise with you."
