Introduction

Thomism has at least three distinct senses. It primarily means the philosophical and theological doctrine of Br. Thomas of Aquino OP (b. 1224/1225–d. 1274). Born into the minor nobility at Roccasecca near Naples, he was first educated as a Benedictine oblate at the monastic school of Monte Cassino, then studied Arts at the newly founded University of Naples, where he encountered the philosophical thought of Aristotle and two Islamic Aristotelians—Avicenna and Averroes. Against the wishes of his family, he was drawn to the Dominicans and took the Dominican habit. He proceeded to Paris and then Cologne, studying under Albertus Magnus. In the midst of conflict between secular masters and the friars, he became Master of Theology at Paris, teaching there twice (1256–1259 and 1268–1272). The rest of his teaching career was spent in Italy. The other two senses of Thomism developed as ways of understanding this first sense of Thomism. The second sense concerns the interpretation and development of his thought by subsequent philosophers and theologians. It did not start auspiciously. In 1270 and again in 1277 the Bishop of Paris condemned certain propositions, mainly Aristotelian, some closely connected with Thomas’s doctrine. There followed attacks on Thomas, mainly by Franciscans, and defense of him, mainly by Dominicans. On 18 July 1323, Aquinas was canonized by Pope John XXII. From the 15th to the 17th century, a series of “classic” commentators explained, defended, and developed the thought of Aquinas. In late medieval universities, the Faculty of Arts usually offered two different ways to study philosophy, the via antiqua (often Aquinas) and the via moderna (nominalism). Just after the Council of Trent, on 15 April 1567 Aquinas was declared a “doctor of the Church” by the Dominican Pope Pius V, his doctrine thereby becoming identified with the magisterial teaching of the Roman Church. The French Revolution spawned “liberalism,” “socialism,” and “positivism” during the 19th century. In reaction, Pope Leo XIII initiated the third sense of Thomism, often called “neo-Thomism,” in his encyclical Aeterni patris (1879). Led by Cardinal Mercier of Louvain and Étienne Gilson of the Sorbonne and Toronto, many “subspecies” of this third sense of Thomism developed in the 20th century. Initially it looked like this third Thomism ended with Vatican Council II, but Thomism revived again during the pontificates of John Paul II and Benedict XVI, in reaction to “postmodernism,” “secularism,” “consumerism,” and “Islamism.”

Introductory Works

Chesterton 1943, Pieper 1982, and McInerny 1990 are for beginners and written by first-rate authors. Weisheipl 1974 is a scholarly biography that concentrates on Aquinas’s doctrine. Though he familiarized himself with the latest research into Thomas’s life, Weisheipl was not inclined to make definitive judgments in this area. Torrell 1996 makes use of all the research into Aquinas’s life done since Weisheipl, especially points uncovered by the Leonine Commission in the process of editing Aquinas’s works. Torrell devotes much space to the details of Aquinas’s life, but he is careful to give a brief account of each of Aquinas’s works. Written with great clarity, the book is required reading for novice and master alike. These two biographies, then, complement each other. One can read Weisheipl for Aquinas’s doctrine and Torrell for his life. Cessario 2005 gives in brief compass a feel for the vast influence of Aquinas on Catholic thought over the centuries. It is especially useful for the second sense of Thomism, that of the “classic commentators.” The last two books are for the more advanced student. Chenu 1964 has become the classic introduction for the budding scholar of Aquinas. Even though over half a century old, it covers all the essential resources, except for those now online. It also contains some of Chenu’s most insightful interpretations of Aquinas and represents the work of the “historical” version of the third sense of Thomism, begun by Gilson. Dufeil 1972 places the reader in Paris right at the beginning of Aquinas’s career. Both Aquinas and Bonaventure were denied Chairs of Theology by the secular Masters of the University of Paris, because the friars refused to go on strike with the rest of the faculty in 1253. They were finally awarded their Chairs only after the intervention of Pope Alexander IV in 1256, and both entered into the polemics in support of the friars’ way of life. While not confined to Aquinas, Dufeil draws the best picture yet of life at the University of Paris during his time there, and during an event in which Aquinas played a major role.
