Dalrymple's thoughtful article on the problem with Islam demands a close reading. In a nutshell, he asserts that Islam is brittle by its rigidity and violent because of weakness.

The unassailable status of the Qu’ran in Islamic education, thought, and society is ultimately Islam’s greatest disadvantage in the modern world. Such unassailability does not debar a society from great artistic achievement or charms of its own: great and marvelous civilizations have flourished without the slightest intellectual freedom. I myself prefer a souk to a supermarket any day, as a more human, if less economically efficient, institution. But until Muslims (or former Muslims, as they would then be) are free in their own countries to denounce the Qu’ran as an inferior hodgepodge of contradictory injunctions, without intellectual unity (whether it is so or not)—until they are free to say with Carlyle that the Qu’ran is “a wearisome confused jumble” with “endless iterations, longwindedness, entanglement”—until they are free to remake and modernize the Qu’ran by creative interpretation, they will have to reconcile themselves to being, if not helots, at least in the rearguard of humanity, as far as power and technical advance are concerned ...

the problem is that so many Muslims want both stagnation and power: they want a return to the perfection of the seventh century and to dominate the twenty-first, as they believe is the birthright of their doctrine, the last testament of God to man. If they were content to exist in a seventh-century backwater, secure in a quietist philosophy, there would be no problem for them or us; their problem, and ours, is that they want the power that free inquiry confers, without either the free inquiry or the philosophy and institutions that guarantee that free inquiry. They are faced with a dilemma: either they abandon their cherished religion, or they remain forever in the rear of human technical advance. Neither alternative is very appealing; and the tension between their desire for power and success in the modern world on the one hand, and their desire not to abandon their religion on the other, is resolvable for some only by exploding themselves as bombs ...

Islam in the modern world is weak and brittle, not strong: that accounts for its so frequent shrillness. The Shah will, sooner or later, triumph over the Ayatollah in Iran, because human nature decrees it, though meanwhile millions of lives will have been ruined and impoverished. The Iranian refugees who have flooded into the West are fleeing Islam, not seeking to extend its dominion, as I know from speaking to many in my city. To be sure, fundamentalist Islam will be very dangerous for some time to come, and all of us, after all, live only in the short term; but ultimately the fate of the Church of England awaits it. Its melancholy, withdrawing roar may well (unlike that of the Church of England) be not just long but bloody, but withdraw it will. The fanatics and the bombers do not represent a resurgence of unreformed, fundamentalist Islam, but its death rattle.
