Graeme Wood, writing in the Atlantic, says that the Western mind does not fully understand what makes the Islamist berserkers of ISIS tick . Excerpt:

There is a temptation to rehearse this observation—that jihadists are modern secular people, with modern political concerns, wearing medieval religious disguise—and make it fit the Islamic State. In fact, much of what the group does looks nonsensical except in light of a sincere, carefully considered commitment to returning civilization to a seventh-century legal environment, and ultimately to bringing about the apocalypse.

The most-articulate spokesmen for that position are the Islamic State’s officials and supporters themselves. They refer derisively to “moderns.” In conversation, they insist that they will not—cannot—waver from governing precepts that were embedded in Islam by the Prophet Muhammad and his earliest followers. They often speak in codes and allusions that sound odd or old-fashioned to non-Muslims, but refer to specific traditions and texts of early Islam.

To take one example: In September, Sheikh Abu Muhammad al-Adnani, the Islamic State’s chief spokesman, called on Muslims in Western countries such as France and Canada to find an infidel and “smash his head with a rock,” poison him, run him over with a car, or “destroy his crops.” To Western ears, the biblical-sounding punishments—the stoning and crop destruction—juxtaposed strangely with his more modern-sounding call to vehicular homicide. (As if to show that he could terrorize by imagery alone, Adnani also referred to Secretary of State John Kerry as an “uncircumcised geezer.”)

But Adnani was not merely talking trash. His speech was laced with theological and legal discussion, and his exhortation to attack crops directly echoed orders from Muhammad to leave well water and crops alone—unless the armies of Islam were in a defensive position, in which case Muslims in the lands of kuffar, or infidels, should be unmerciful, and poison away.

The reality is that the Islamic State is Islamic. Very Islamic. Yes, it has attracted psychopaths and adventure seekers, drawn largely from the disaffected populations of the Middle East and Europe. But the religion preached by its most ardent followers derives from coherent and even learned interpretations of Islam.

Virtually every major decision and law promulgated by the Islamic State adheres to what it calls, in its press and pronouncements, and on its billboards, license plates, stationery, and coins, “the Prophetic methodology,” which means following the prophecy and example of Muhammad, in punctilious detail. Muslims can reject the Islamic State; nearly all do. But pretending that it isn’t actually a religious, millenarian group, with theology that must be understood to be combatted, has already led the United States to underestimate it and back foolish schemes to counter it. We’ll need to get acquainted with the Islamic State’s intellectual genealogy if we are to react in a way that will not strengthen it, but instead help it self-immolate in its own excessive zeal.

A small quibble: I hate how modern writers tend to use the word “medieval” to describe Islamic fundamentalism. Whatever the faults of the Christian Middle Ages in our modern view, they were a time of incredible artistic and intellectual ferment. Think of the cathedrals. Think of the Summa. Think of the Divine Comedy. Those were all products of the medieval times in Christendom. What is ISIS producing? Anyway, more:

It would be facile, even exculpatory, to call the problem of the Islamic State “a problem with Islam.” The religion allows many interpretations, and Islamic State supporters are morally on the hook for the one they choose. And yet simply denouncing the Islamic State as un-Islamic can be counterproductive, especially if those who hear the message have read the holy texts and seen the endorsement of many of the caliphate’s practices written plainly within them.

Muslims can say that slavery is not legitimate now, and that crucifixion is wrong at this historical juncture. Many say precisely this. But they cannot condemn slavery or crucifixion outright without contradicting the Koran and the example of the Prophet. “The only principled ground that the Islamic State’s opponents could take is to say that certain core texts and traditional teachings of Islam are no longer valid,” Bernard Haykel says. That really would be an act of apostasy.

The Islamic State’s ideology exerts powerful sway over a certain subset of the population. Life’s hypocrisies and inconsistencies vanish in its face. Musa Cerantonio and the Salafis I met in London are unstumpable: no question I posed left them stuttering. They lectured me garrulously and, if one accepts their premises, convincingly. To call them un-Islamic appears, to me, to invite them into an argument that they would win. If they had been froth-spewing maniacs, I might be able to predict that their movement would burn out as the psychopaths detonated themselves or became drone-splats, one by one. But these men spoke with an academic precision that put me in mind of a good graduate seminar. I even enjoyed their company, and that frightened me as much as anything else.

Read the whole thing, dear WEIRDoes. It’s a remarkable piece of explanatory journalism. I did not realize until reading it that ISIS is an apocalyptic sect that believes it is working to bring about its own version of Armageddon (which is why it is trying to bait the West into invading its lands). These people are even more radical than the Khmer Rouge, if you can believe it.

In his piece, Wood quotes Orwell warning his readers against underestimating the power of fascism over men’s minds. Said Orwell:

Fascism is psychologically far sounder than any hedonistic conception of life … Whereas Socialism, and even capitalism in a more grudging way, have said to people “I offer you a good time,” Hitler has said to them, “I offer you struggle, danger, and death,” and as a result a whole nation flings itself at his feet … We ought not to underrate its emotional appeal.

These young people traveling to the battlefield to wage and to die in jihad aren’t going for liberty, for riches, for the opportunity to turn themselves into females, and so forth. They are going for meaning. They may be crazy, but they are not insane.
