The Incoherence of the Philosophers

Could the greatest mind in Islamic theology prove that the most brilliant philosophers of his age were actually teaching heresy? In a single book, Abū Ḥāmid al‑Ghazālī did exactly that - and changed the course of Islamic thought forever. This is the book that made philosophy tremble.

The Incoherence of the Philosophers (Tahāfatu al‑Falāsifah) is Al‑Ghazālī’s devastating critique of the Neoplatonic‑Aristotelian tradition as represented by al‑Fārābī and, most importantly, Ibn Sīnā (Avicenna). Written near the height of his intellectual powers, the work systematically dismantles twenty philosophical positions that Al‑Ghazālī deemed dangerous to orthodox faith. Seventeen of them he declares heretical innovations; three - the world’s pre‑eternity, God’s ignorance of particulars, and the denial of bodily resurrection - he brands outright unbelief.

But this is no mere polemic. Al‑Ghazālī engages deeply with the philosophers’ arguments, showing where they fail to meet their own standards of proof. His purpose is not to destroy philosophy but to show that its pretensions to certainty in metaphysical matters are unfounded. The book forced subsequent thinkers, including Ibn Rushd (Averroës) who wrote The Incoherence of the Incoherence in response, to clarify their positions and ultimately helped carve out a space for rational inquiry within the boundaries of Islamic orthodoxy.

Michael E. Marmura’s translation is the most accurate and readable English version available, based on the critical Arabic edition. His introduction situates the work within Al‑Ghazālī’s intellectual development and the broader tradition of Islamic philosophy.

Why We Love It
At Kitab Markaz, we treasure books that ask the hard questions. The Incoherence of the Philosophers does exactly that - and it refuses to give easy answers. Al‑Ghazālī is often portrayed as the enemy of reason, but reading this book reveals a meticulous thinker who respects logic while refusing to let it overreach. Marmura’s translation makes this masterpiece accessible to English‑reading Pakistanis who want to understand their intellectual heritage. It’s the book we recommend to students of philosophy, Islamic studies, and anyone who wonders whether faith and reason must always be at war. The answer might surprise you.

About the Author and Translator:
Abū Ḥāmid Muḥammad Ibn Muḥammad Al‑Ghazālī (1058–1111) is one of the most influential figures in Islamic history. Philosopher, theologian, jurist, and Sufi mystic, his works - especially The Revival of the Religious Sciences - shaped Muslim thought for centuries. After a period of doubt, he abandoned his prestigious teaching post to become a wandering ascetic, eventually achieving what he described as “certainty” through Sufism. His writings continue to be studied across the Muslim world.

Michael E. Marmura (1929–2009) was a distinguished professor of Islamic philosophy at the University of Toronto. A native of Jerusalem, he devoted his career to editing and translating key Arabic philosophical texts, including works of Ibn Sīnā and Ibn Rushd. His translation of The Incoherence of the Philosophers is widely considered the definitive English version.
