Ibn Rushd (1126-1198), better known as Averroes, is said to be the greatest among the Muslim commentators on Aristotle and is especially known for his influence on medieval Christendom and on medieval and Renaissance science and philosophy. This volume presents a readable translation of his middle commentaries on Aristotle's Categories and De Interpretation--the first of his middle commentaries on Aristotle's logical treatises. Originally published in 1983. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-pr.
