Abstract

Dating from 1267-1268, at the end of his time in Rome, St. Thomas Aquinas's Commentary on Aristotle's On the soul is the first of his commentary works on Aristotle, followed shortly thereafter by his writings on Aristotle's On sense and what is sensed and On memory and recollection, also included in this volume. Although commenting on Aristotle was not among Aquinas's duties as a university master, he seems to have undertaken this task in part as an aid to his theological work: just as he later comments on Aristotle's Nicomachean ethics while drafting the material on moral theology in the Secunda Pars of the Summa theologiae, so too his writing of the Commentary on Aristotle's On the soul was contemporaneous with his composition of questions 75-89 in the Prima Pars, on the human soul. Displaying a sound grasp of Aristotle's thought as well as a deeply developed understanding of the human person, the Commentary on Aristotle's On the soul finds Aquinas working for the first time with William of Moerbeke's new Latin translations of On the soul and its paraphrase by Themestius. This important work of Aquinas is presented here with his other two earliest writings on Aristotle in a two-column Latin-English facing format.
