Who or what

Abu al-Walid Muhammad ibn Ahmad ibn Rushd (1126–1198), known as Averroes, was an Andalusian polymath.

He wrote extensive commentaries on Aristotle that became standard texts in European universities.

Why it mattered

Ibn Rushd argued that philosophy and religion were two paths to the same truth — reason and revelation cannot contradict.

His "incompatibility of incompatibility" argued that apparent conflicts between philosophy and scripture arise from misinterpretation.

Key works and moments

His "Tahafut al-Tahafut" (Incoherence of the Incoherence) defended philosophy against Al-Ghazali's critiques.

His medical work "Al-Kulliyat" (Colliget) was a comprehensive medical encyclopedia used in Europe.

Further detail

He distinguished three levels of discourse: rhetorical (for masses), dialectical (for theologians), demonstrative (for philosophers).

His concept of "unity of the intellect" influenced Latin Averroism and debates at the University of Paris.

Legacy

"The Commentator" (as he was known in Latin) shaped Aquinas, Maimonides, and all of medieval scholasticism.

Averroism became a major intellectual movement in 13th-century Europe.
