Al-Ghazali vs Averroes

Al-Ghazali and Averroes are the two great medieval Islamic philosophers whose dispute over the legitimacy of Greek-influenced philosophy shaped the trajectory of Islamic thought. Their works The Incoherence of the Philosophers (Al-Ghazali) and The Incoherence of the Incoherence (Averroes' point-by-point reply) frame the dispute.

Where they agree

Both held that the Quran is the highest source of truth, both were trained jurists, and both engaged seriously with the Greek philosophical tradition transmitted to the Islamic world by Al-Farabi and Avicenna. Both treated the integration of revelation and rational inquiry as a central task.

Where they disagree

Al-Ghazali argued that the falasifa, the Aristotelian-Neoplatonic philosophers, had committed several errors so serious that holding them constituted unbelief: the eternity of the world, the denial of God's knowledge of particulars, and the denial of bodily resurrection. He further attacked the necessity of natural causation as such, defending a form of occasionalism. Averroes replied that the philosophers had been misrepresented and that properly interpreted Aristotelian philosophy is consistent with Islamic revelation, with both natural causation and the integrity of philosophical inquiry preserved.

    There is no denying existence itself. Something must exist and anyone who says nothing exists at all makes a mockery of sense and necessity. The proposition that there is no denying being itself, then, is a necessary premise. Now this Being which has been admitted in principle is either necessary or contingent… What this means is that a being must be self-sufficient or dependent… From here we argu
