Aristotle Commentaries

Exposure to the works of Aristotle was intellectually stimulating for St. Thomas. Throughout St. Thomas’s life this exposure was continually expanding as the works of the Greek philosopher were translated into Latin. St. Thomas found Aristotle’s philosophy helpful in making key distinctions and in providing a foundation for his own explorations. Not only did St. Thomas quote Aristotle extensively in his works, he also wrote commentaries on many of Aristotle’s greatest works. In exploring Aristotle’s works, St. Thomas Aquinas provides a Catholic insight into Aristotle’s philosophy while letting that philosophy form his understanding of the world.

In these commentaries, which include the original texts of Aristotle in Greek, Latin, and English, the best of Greek and scholastic philosophy is presented.
