Averroes (Ibn Rushd)

A Scholar Grows Up in Córdoba

In 1126, in the busy Andalusian city of Córdoba, a child was born who would become a judge, doctor, philosopher, and student of the stars. His name was Abū al-Walīd Muhammad ibn Ahmad Ibn Rushd, although Latin readers later called him Averroes.

Ibn Rushd belonged to a respected family of Muslim legal scholars: both his father and his grandfather served as judges. He did not leave an autobiography, so parts of his childhood remain unknown, but historical records show that he studied Islamic law and religious sciences as well as medicine, philosophy, and astronomy.

Judge, Doctor, and Observer

By 1153, Ibn Rushd was in Marrakesh, where he recorded observations of stars and thought about how the heavens moved. He later served as a judge in Seville in 1169 and Córdoba in 1171, work that required him to study evidence, laws, and disagreements carefully.

Around this period, the philosopher Ibn Tufayl introduced him to the Almohad caliph Abū Yaʿqūb Yūsuf. The ruler asked Ibn Rushd to make Aristotle's difficult works more accessible, and Ibn Rushd eventually became both chief judge of Córdoba and the caliph's physician in 1182.

Explaining Philosophy and Medicine

For about three decades, Ibn Rushd wrote short, middle, and detailed commentaries on nearly all the works of Aristotle available to him. He did more than repeat an ancient thinker: he compared arguments, corrected interpretations he thought were mistaken, and developed ideas that later reached readers through Arabic, Hebrew, and Latin manuscripts.

His Kulliyyāt fī al-ṭibb, a book about general principles of medicine, became known in Latin as the Colliget. In the Decisive Treatise, he argued that careful philosophical reasoning and Islamic religious law could work together, while his astronomy questioned parts of Ptolemy's system even though it kept the Earth-centered model accepted in his time.

Exile, Return, and a Lasting Conversation

In 1195, Ibn Rushd fell out of favor with the Almohad court for reasons historians still debate, and he was exiled to Lucena near Córdoba. He was rehabilitated before his death, returned to Marrakesh, and died there on December 10, 1198.

Many of his Arabic texts later disappeared, but Hebrew and Latin translations preserved important parts of his work. Medieval European scholars called him “the Commentator” because his explanations of Aristotle were so influential, yet his wider contribution reached law, medicine, astronomy, and Muslim, Jewish, and Christian philosophy. Ibn Rushd's story shows how one person's patient effort to examine hard questions can keep a conversation moving across languages, cultures, and centuries.
