Islam fell completely under the sway of Aristotelian and neo-Platonic thought. Listen to the incredible praise that Averroes had for Aristotle:
I consider that that man (Aristotle) was a rule and exemplar which nature devised to show the final perfection of man…the teaching of Aristotle is the supreme truth, because his mind was the final expression of the human mind. Wherefore it has been well said that he was created and given to us by divine providence that we might know all there is to be known. Let us praise God, who set this man apart from all others in perfection, and made him approach very near to the highest dignity humanity can attain.
