Ibn Rushd
The Commentator
In a palace library in Marrakesh, sometime around 1169, a young physician from Córdoba stood before the most powerful man in the Islamic West and felt his heart seize in his chest. The Almohad caliph Abu Yaqub Yusuf I — a man who controlled territories stretching from the Atlantic coast to the edge of Egypt — had asked him a single question: what do the philosophers say about the heavens? Are they eternal, or were they created in time? It was the kind of question that had sent men to the scaffold. Ibn Rushd — physician, jurist, philosopher, and the grandson of Córdoba's greatest judge — opened his mouth, thought of how to be careful, and almost lied. What he said instead, and the life he lived afterward, would transform the intellectual foundations of two civilisations: the Islamic world he was born into, and the Latin Christian world he never visited but whose universities he would reshape from the grave.
“Knowledge is the conformity of the object and the intellect.”
1126–1198
Born in Córdoba on 14 April 1126 into a family of distinguished Maliki jurists — his grandfather Ibn Rushd the Elder had served as chief qadi of Córdoba, and his father held the same position. He died in Marrakesh on 11 December 1198 at the age of seventy-two, having spent his final years rehabilitated at the Almohad court after a period of disgrace. His body was later transferred to Córdoba for burial — carried on a mule alongside the counterweight of his own collected books.
~38
Ibn Rushd wrote approximately thirty-eight commentaries on the works of Aristotle — more than any other scholar in history, and in three tiers: short epitomes, middle paraphrases, and long line-by-line expositions. When these were translated into Latin by Michael Scot in the 1220s, medieval European scholars called Aristotle 'The Philosopher' and Ibn Rushd 'The Commentator' — as though no other names were needed.

More than fifty separate Latin editions of Ibn Rushd's works were published in the first century of European printing (1472–1550), making him one of the most-printed authors of the early modern era. His commentaries were required reading at the University of Paris and other major European universities for over three hundred years — a span of influence that dwarfs most philosophers of any era.
70+
Beyond his Aristotle commentaries, Ibn Rushd produced approximately seventy authenticated works spanning philosophy, medicine, jurisprudence, astronomy, and linguistics. His medical encyclopedia, the Kulliyyat (Colliget in Latin), was a standard reference in European medicine for centuries. His legal primer, Bidayat al-Mujtahid, remains a foundational text in comparative Islamic jurisprudence and is still studied in Islamic law schools today.

Defining Events
The Question at Marrakesh
When Caliph Abu Yaqub Yusuf I complained that existing Arabic translations of Aristotle were impenetrably obscure, his court philosopher Ibn Tufayl confessed he was too old to undertake a complete new commentary. He introduced the thirty-three-year-old Ibn Rushd instead. The caliph tested his visitor with a question about Aristotle and the eternity of the heavens — a theological minefield. Ibn Rushd, initially cautious, revealed his philosophical knowledge when the caliph revealed his own. From that afternoon, the most ambitious commentary project in intellectual history was commissioned. Ibn Rushd would spend the next fifteen years producing line-by-line expositions of virtually every work Aristotle had written.
The Incoherence of the Incoherence
Al-Ghazali's Tahafut al-Falasifa (The Incoherence of the Philosophers, 1095) had been the most devastating attack on Aristotelian philosophy in Islamic history, declaring that three philosophical propositions constituted outright disbelief. No philosopher had answered it for eighty-five years. Ibn Rushd's response, Tahafut al-Tahafut (The Incoherence of the Incoherence), was a point-by-point demolition of al-Ghazali's arguments. He also wrote the Fasl al-Maqal (The Decisive Treatise), arguing that the study of philosophy was not merely permitted by Islamic law but obligatory for qualified Muslims. The conclusions were bold enough to have him burned in effigy — but the caliph's protection held, for now.
The Book Burning
After the Almohad victory at the Battle of Alarcos over the Castilians, Caliph Abu Yusuf Yaqub al-Mansur — riding a wave of political confidence — allowed conservative theologians their long-sought opportunity and used Ibn Rushd as a political scapegoat. Ibn Rushd was publicly denounced in the mosque of Córdoba. His books on philosophy and natural science were burned throughout Al-Andalus. He was exiled to Lucena — a small town south of Córdoba with a largely Jewish population, cutting him off from the Muslim scholarly world. A general ban on philosophical study was proclaimed across Almohad territories. The exile lasted roughly two years; he was rehabilitated and summoned back to Marrakesh in 1197, where he died the following year. Within decades, the books he had burned would be the most sought-after texts in European universities.
Timeline
Born in Córdoba
Abu al-Walid Muhammad ibn Ahmad ibn Rushd is born in Córdoba on 14 April 1126, into one of the most distinguished families in Al-Andalus. His grandfather, Ibn Rushd the Elder, was the chief Maliki qadi of Córdoba and one of the most authoritative jurists in Al-Andalus. His father was also a qadi. The child born into this family would inherit both the judicial office and the title — and use both to build something his ancestors could not have imagined.
Introduction to Ibn Tufayl
The young Ibn Rushd travels to Marrakesh, the Almohad capital, where he encounters Ibn Tufayl — court physician, philosopher, and author of the philosophical novel Hayy ibn Yaqdhan (known in Europe as Philosophus Autodidactus). Ibn Tufayl is a man of extraordinary culture and intellectual range, and he recognises in Ibn Rushd a mind suited to the task he himself can no longer undertake: a comprehensive, clear commentary on the entire body of Aristotle's work. The friendship between the older and younger philosopher will shape the next four decades of intellectual history.
The Commission at Court
Ibn Tufayl introduces Ibn Rushd to Caliph Abu Yaqub Yusuf I, who asks the young physician about Aristotle and the eternity of the heavens. After a tense opening exchange, Ibn Rushd reveals his philosophical range; the caliph, himself a man of learning, commissions the great commentary project. Ibn Rushd is also appointed qadi of Seville — the first step in the judicial career he will hold alongside his philosophical and medical work. Within a few years he will be chief qadi of Córdoba, the same position his grandfather had held.
The Commentary Years
Over a decade and a half, working in Seville and Córdoba, Ibn Rushd composes his massive commentary project on Aristotle. He writes in three formats for each work: a short epitome (jami') for beginners, a middle-length paraphrase (talkhis) for intermediate students, and a long, line-by-line exposition (tafsir) for advanced scholars. The works covered include the Physics, Metaphysics, De Anima (On the Soul), Posterior Analytics, Nicomachean Ethics, Politics, De Caelo, and more. It is the most systematic engagement with Aristotle ever attempted in any language.
The Incoherence of the Incoherence
Ibn Rushd completes his Tahafut al-Tahafut — the Incoherence of the Incoherence — a systematic rebuttal of al-Ghazali's 1095 attack on Aristotelian philosophy. He also writes the Fasl al-Maqal (Decisive Treatise), arguing that the pursuit of philosophy is legally obligatory for qualified Muslims, and the Kashf 'an Manahij (Exposition of the Methods of Proof), a detailed examination of Islamic theology. Together, these three works represent the boldest defense of rational philosophy ever mounted within Islamic thought.
Royal Physician in Marrakesh
Following the death of Ibn Tufayl, Ibn Rushd is appointed personal physician to Caliph Abu Yaqub Yusuf I in Marrakesh — the highest court position available to a scholar. The caliph dies two years later at the siege of Santarém in Portugal (1184), killed in battle. His son Abu Yusuf Yaqub al-Mansur ('the Victorious') succeeds him and initially continues the patronage of Ibn Rushd, naming him court physician and allowing him to continue his philosophical work.
Exile and Book Burning
Emboldened by the Almohad victory at the Battle of Alarcos (1195), al-Mansur yields to conservative jurists who seize the political high-water mark to press their theological agenda, using Ibn Rushd as a scapegoat. Ibn Rushd is publicly denounced in the mosque of Córdoba. His philosophical and scientific books are burned. He is exiled to Lucena, a town south of Córdoba with a largely Jewish population. A general ban on the study of philosophy is proclaimed throughout Al-Andalus. The man who had argued that philosophy was legally obligatory for Muslims finds his books reduced to ash by order of the man he had served as physician.
Death in Marrakesh
Rehabilitated by al-Mansur in 1197 and summoned back to Marrakesh, Ibn Rushd dies there on 11 December 1198, aged seventy-two. His body is first buried in Marrakesh; months later, his family arranges its transfer to Córdoba — carried by mule, with his collected books serving as counterweight on the other side of the panniers. In the Latin West, his commentaries are already being translated. Within thirty years they will be required reading in every major European university. Dante will place him in Limbo beside Aristotle, Plato, and Socrates. Thomas Aquinas will cite him more than five hundred times. He dies forgotten in the world that produced him, and immortal in the world that never met him.
Key Figures
Ibn Tufayl
Abu Bakr Muhammad ibn Tufayl (c. 1105–1185) was the philosopher, physician, and court favourite of Caliph Abu Yaqub Yusuf I who introduced Ibn Rushd to the Almohad court and commissioned the Aristotle commentaries when he himself grew too old to undertake them. His philosophical novel Hayy ibn Yaqdhan — known in Europe as Philosophus Autodidactus — imagines a child raised alone on a desert island who arrives, through reason alone, at the same truths as revealed religion. It was the guiding framework for Ibn Rushd's entire philosophical project: that reason and revelation, properly understood, cannot contradict one another. Without Ibn Tufayl's mentorship and court access, the Aristotle commentaries might never have been written. He died in 1185, leaving Ibn Rushd as the foremost philosopher in the Islamic West.
Maimonides
Moses Maimonides (Moses ben Maimon, 1138–1204) was born in Córdoba eight years after Ibn Rushd and pursued the same philosophical project in a different religious tradition: the reconciliation of Aristotelian reason with revealed scripture — Torah rather than Quran. His family fled Almohad persecution in 1148 (when Ibn Rushd was twenty-two), settling eventually in Cairo. His Guide for the Perplexed (c. 1190) is structurally Averroist — grounded in the same conviction that philosophy and revealed religion, rightly interpreted, cannot contradict one another. Maimonides read and cited Ibn Rushd's medical works. The two men — one Muslim, one Jewish, both Córdoban — never met, yet together they represent the pinnacle of Andalusian intellectual life and the greatest medieval synthesis of Athens and Jerusalem.
The Legacy of Ibn Rushd
Ibn Rushd accomplished something that history had never seen and has rarely repeated: he became indispensable to a civilisation that did not want him. The Islamic world that burned his books went on to treat philosophy with increasing suspicion; the rationalist tradition he championed never fully recovered in the Sunni world. But the Latin West — which received his commentaries in translation just decades after his death — built universities around them. Thomas Aquinas wrote his entire philosophical theology in dialogue with Averroes, citing him more than five hundred times. Dante placed him in the company of Aristotle, Homer, and Plato. The physicians of Bologna and Paris taught from his Colliget for three hundred years. Roger Bacon called him 'the lord of philosophers.' He is the only medieval thinker to have shaped, simultaneously and profoundly, the intellectual traditions of Islam, Judaism, and Christianity.
He was born a judge's son in the most cultured city in Europe, commissioned by a philosopher-king to explain the greatest philosopher of antiquity, exiled for his trouble, and rehabilitated too late. He died in Marrakesh having never seen the Europe he would make. His books crossed the Mediterranean without him. Read his story in his own words in the first-person ePub.
