Averroës, the greatest Aristotelian of the Islamic philosophical tradition, composed some thirty-eight commentaries on the "First Teacher's" corpus, including three separate treatments of De Anima ("On the Soul"): the works commonly referred to as the Short, Middle, and Long Commentaries. The Middle Commentary—actually Averroës's last writing on the text-remains one of his most refined and politically discreet treatments of Aristotle, offering modern readers Averroës's final statement on the material intellect and conjunction as well as an accessible historical window on Aristotle's work as it was interpreted and transmitted in the medieval period.
