Abu al-Walid Muhammad ibn Ahmad ibn Rushd (1126 – 1198 CE), known in Latin Europe as Averroes, was a polymath of Al-Andalus born into a distinguished family of judges in Córdoba. Trained in law, medicine, theology, astronomy, and philosophy, he served as a religious judge (qadi) in Seville and Córdoba and as court physician, yet his lasting fame rests on his sustained engagement with Aristotle. Across short, middle, and long commentaries, Ibn Rushd worked to recover the Greek philosopher's arguments in their own terms, earning in the West the simple title "The Commentator." His treatise The Incoherence of the Incoherence answered al-Ghazali's critique of philosophy and defended the compatibility of reasoned demonstration with revelation. When his works passed into Hebrew and Latin, they ignited the movement later called Latin Averroism and pressed thinkers from Thomas Aquinas onward to confront the relationship between faith and reason. Late in life he fell briefly out of favor and saw some of his writings censured, and he died in Marrakesh. Much of his philosophical corpus survived most fully in translation, where it became a foundation stone of medieval European universities.
