Averroës (Aver`roës) , an Arabian physician and philosopher, a Moor by birth and a native of Cordova; devoted himself to the study and the exposition of Aristotle, earning for himself the title of the “Commentator,” though he appears to have coupled with the philosophy of Aristotle the Oriental pantheistic doctrine of emanations (1126-1198).
