The philosophy of the desert can only begin over again. It cannot grow; it cannot have what Protestants call progress and Catholics call development. There is death and hell in the desert when it does begin over again. There is always the possibility that a new prophet will rediscover the old truth; will find again written on the red sands the secret of the obvious. But it will always be the same secret, for which thousands of these simple and serious and splendidly valiant men will die. The highest message of Mahomet is a piece of divine tautology. The very cry that God is God is a repetition of words, like the repetitions of wide sands and rolling skies.
-G.K. Chesterton: The New Jerusalem (1920)
