This created major problems, notably with respect to Aristotle’s Physics and Metaphysics. More specifically, the Greek concept of causality was deemed incompatible with the Koranic understanding of God’s omnipotence, which it seemed to limit. And although some scholars like Al-Farabi, Al-Andalusi, Avicenna and Averroes were genuinely receptive to Greek influences, they were unable to reconcile Aristotelian metaphysical concepts with the content of Islamic revelation.

Moreover, Islamic works that did reflect Greek influence were usually not well received. Averroes’ books were burnt (only Latin translations of his commentaries on Aristotle have survived, all of his commentaries in Arabic having been lost or destroyed) and his disciples were found only among Jews and Christians. While the Koran may well offer its adherents a rational view of the world, Muslim rationalism has very little in common with Western rationalism. The notion of kalâm, sometimes translated as “Islamic philosophy”, was understood by the famous Muslim theologian Al-Ghazali as a means of “protecting the faith against the disruptions of innovators” and was, therefore, alien to the Greek concept of philosophy.

Finally, Muslim scholars were quick to realize that Aristotle’s political theories were inapplicable in a Muslim state, where politics, law and religion are closely intertwined. This explains why the Greco-Roman legal system was never envisaged, even by Averroes, as a source of juridical thinking in the Islamic world.

Second, Greek knowledge became accessible to the Islamic world thanks to the work of Eastern Christian scholars who translated Greek works into their own Syriac language, and then from Syriac into Arabic.
