Averroes (Ibn Rushd)
Andalusian philosopher (1126–1198) whose commentaries on Aristotle transmitted Greek philosophy to medieval Europe and triggered the Scholastic revolution, while his Aristotelian rationalism was condemned by Islamic orthodoxy, demonstrating how the same ideas can fertilize one civilization while being rejected by another.
Ibn Rushd (Latinized as Averroes) was the most important philosophical transmission point between ancient Greece and medieval Europe. Working in Muslim Andalusia (Spain), he wrote comprehensive commentaries on virtually all of Aristotle's works, the most thorough and accurate expositions of Aristotelian thought produced in the medieval period. These commentaries, translated into Latin in the 12th–13th centuries, gave European scholars direct access to Aristotle for the first time in centuries.
The impact on European thought was seismic: Thomas Aquinas built his entire philosophical system on the synthesis of Averroes's Aristotle with Catholic theology. The University of Paris was convulsed by 'Averroism', the radical Aristotelian position that reason and faith might reach contradictory conclusions, with reason authoritative in its own domain. This triggered a crisis in medieval theology and ultimately forced the development of systematic Christian philosophy (Scholasticism) as a response.
In the Islamic world, his fate was opposite: condemned by the Almohad caliph in 1195 for prioritizing reason over revelation, his books were burned and he was briefly exiled. The Ash'arite theological tradition (which had defeated Mu'tazilite rationalism in the 10th century) made philosophical rationalism suspect in mainstream Islam. Averroes's influence was greater in Christendom than in the civilization that produced him.

Frequently asked questions
Why was Averroes important to medieval Europe? ＋
He wrote the most comprehensive commentaries on Aristotle in the medieval period. When these were translated into Latin, European scholars gained systematic access to Aristotle for the first time. Thomas Aquinas built his philosophical system on Averroes's Aristotle. Without him, the Scholastic synthesis of reason and faith that defined medieval European thought might not have happened.
Why was Averroes rejected in the Islamic world? ＋
He argued that reason and revelation are both valid paths to truth, and that philosophical reasoning deserves authority in its own domain. The Almohad caliph condemned this as prioritizing reason over revelation; his books were burned. The Ash'arite theological tradition that dominated Sunni Islam had already rejected the Mu'tazilite rationalists, Averroes fell into the same pattern.
