Ibn Rushd (Abū al-Walīd Muḥammad ibn Rushd)

'The Commentator' on Aristotle who defended philosophy against al-Ghazālī.

Overview

The greatest Aristotelian of the Islamic world, the Andalusian jurist, physician, and philosopher Ibn Rushd (Averroes) wrote such thorough commentaries on Aristotle that the Latins simply called him 'the Commentator'. In The Incoherence of the Incoherence he answered al-Ghazālī, defending the philosophers and the harmony of philosophy and religion as two paths to one truth. His works, translated into Latin and Hebrew, shaped Europe even more than the Islamic world, sparking 'Latin Averroism'.

What they supported — and why

The harmony of philosophy and religion

SupportedPhilosophy and scripture are two roads to the same truth: scripture's outer sense is for the many, its inner meaning for the philosophers.

WhyGod gave both reason and revelation, so they cannot truly conflict; where they seem to, scripture must be read allegorically.

Defense of Aristotle against al-Ghazālī

SupportedThe philosophers' key doctrines are defensible, and al-Ghazālī's attacks fail.

WhyRigorous Aristotelian demonstration, properly understood, withstands the theologians' objections.

The unity of the intellect

SupportedThe material intellect by which all humans think is one and separate, shared by all.

WhyHis reading of Aristotle's De Anima concludes the immaterial intellect cannot be individuated by bodies — a doctrine the Latins seized on and disputed.
