Karen Armstrong, whose book entitled The Battle for God: Fundamentalism in Judaism, Christianity and Islam is currently occupying about a third of my reading time (along with James Carroll's House of War and R. A. Scotti's Basilica: The Splendor and the Scandal: Building St. Peter's), has an essay in tomorrow's Guardian on the divide separating radical Muslims from their moderate brethren. Armstrong is a very perceptive observer of world religions and her assessment of Islam in this essay helps to situate jihadists within the broader realm of religious fundamentalisms.
