From a review in the New Yorker magazine (HT) of David Levering Lewis, God’s Crucible: Islam and the Making of Europe, 570 to 1215, in which the author

clearly regrets that the Arabs did not go on to conquer the rest of Europe. The halting of their advance was instrumental, he writes, in creating “an economically retarded, balkanized, and fratricidal Europe that . . . made virtues out of hereditary aristocracy, persecutory religious intolerance, cultural particularism, and perpetual war.” It was “one of the most significant losses in world history and certainly the most consequential since the fall of the Roman Empire.” This is a bold hypothesis.

To say the least. It is of course true that in the twelfth and thirteenth centuries Muslims had been in possession of a number of Aristotle’s works in Arabic that were not readily available in the Latin West. It isn’t so clear, however, that the depth and breadth of Greek philosophy and the classical virtues were saved by Islamic philosophers during the West’s “dark” ages. There’s much more on that here, including this summary:

The Arabic translations, although they did serve as an early reintroduction for some Western Europeans to Greek thought, didn’t “save” Greek knowledge as it had never been lost. It had been preserved in an unbroken line since Classical times by Greek, Byzantine Christians, who still considered themselves Romans, and it could be recovered there. There was extensive contact between Eastern and Western Christians at this time; sometimes amiable, sometimes less so and occasionally downright hostile, but contact nonetheless. The permanent recovery of Greek and Classical learning was undertaken as a direct transmission from Greek, Orthodox Christians to Western, Latin Christians. There were no Muslim middlemen involved.

In any case, here’s the take of the New Yorker reviewer on Lewis’ book:

I can foresee a time when another matter important to us, the threat of ecological catastrophe, will prompt a historian to write a book in praise of the early Europeans whom Lewis finds so inferior to the Muslims. The Franks lived in uncleared forests, while the Muslims built fine cities, with palaces and aqueducts? All the better for the earth. The Franks were fond of incest? Endogamy keeps societies small, prevents the growth of rapacious nation-states. The same goes for the Franks’ largely barter economy. Trade such as the Muslims practiced—far-flung and transacted with money—leads to consolidation. That’s how we got global corporations.

So, the development of free market economies so often attributed to Western civilization are actually due to Muslim nation-states…and for that reason we ought to prefer European culture!

How refreshing!
