What "Arab" scholarship would that be? Plato and the Eliatics were merely rediscovered; Arab philosophic "scholarship" is still defined by a single person - Alfarabi.
Boethius, Augustine, Cassiodorus, and Alcuin were Arabs??? Which "crusades" were in Toledo and Monte Cassino??? Amazing the things they are doing with Aristotle, Cicero, and Plato in Saudi Arabia these days...
Where is this "discovered" Western thought generally found today??? Lot of Aristotelians in downtown Cairo and Mecca???
Ibn Khaldun's Muqaddimah is generally thought of as a hell of a good history. Arab scholarship, during years before the crusades, WAS far beyond anything in western europe. The fact that it was based upon Greek thought doesn't mean much: at least they were civilized enough to preserve greek learning!
