Here, I should like to tell a story, beginning with how the works of Aristotelian philosophy came to exist in Latin translations, then moving to the project of transforming Christian theology into an Aristotelian “science.” After that, I would like to look a bit more closely at the case of Br. Thomas of Aquino and his dependence upon the Muslim philosopher Ibn Sīnā . Finally, I shall end by drawing some wider conclusions based upon this important example.

This paper has two goals: 1) to understand justice as a cardinal virtue, according to Aquinas; and 2) to use his conception of justice as a cardinal virtue to understand how one engages in acts of “general” justice. The argument proceeds in four stages: 1) how Aquinas understands the virtues by looking to their “objects”; 2) the two distinct “modes” of the four cardinal virtues, as “general” and “specific” virtues; 3) the triangle of three kinds of justice, seen in terms (...) of their “objects”; 4) Aquinas’s doctrine of justice as a “general” virtue (ST 2-2.58.5–6) shows that we can perform operations of “general” justice in two ways, as do the ruler and his minsters, and as ordinary folk do. Surprisingly, it is the latter mode of acting for “general” justice that is primary, not the former. (shrink)

Thomas of Aquino, from the time he wrote his commentary on the ’Sentences’ through writing the ’Summa of Theology’, recognized how far beyond Aristotle’s was the rational theology of Avicenna. After perfecting his approach to proving the existence of God in the "five ways," Aquinas further developed Avicenna’s organization for treating God’s nature by simplifying Avicenna’s often convoluted thought and added his own developments in content and order. In sum, Aquinas’s treatment of God’s nature depends closely upon Avicenna’s treatment of (...) the subject in his ’Metaphysics’ 8.3-7, even more so than upon Aristotle. This conclusion can be seen by comparing the doctrines of Aristotle, Avicenna and Aquinas on the divine nature. (shrink)

Si bien la importancia de Avicena como fuente del pensamiento de Tomás de Aquino es generalmente reconocida, los detalles de esa dependencia apenas comienzan a trabajarse. Este artículo se ocupa de las enseñanzas de Avicena en lo que respecta a los “sujetos” de las ciencias teoréticas —física, matemáticas y metafísica— tal y como se presentan en la Introducción al Libro de la Curación. Posteriormente, se muestra su influencia en el comentario de Tomás de Aquino al De trinitate, de Boecio, q. (...) 5, art. 1. A través de una comparación entre Avicena y Tomás se muestra la profunda influencia que tuvo Avicena en la comprensión tomista del rango de las tres clases de ciencias teoréticas. (shrink)

Aquinas’s theology, as presented in his Scriptum, is “scientific” in the Aristotelian sense of this term. Some of its arguments for conclusions are based on theology’s “proper” principles—the articles of faith—but many others are purely rational demonstrations. As the basis for his rational arguments in theology, and in particular his treatment of the divine essence in d. 8, he introduces philosophical principles, and offers dialectical arguments for them, which are thoroughly Avicennian. In order to understand Aquinas’s commentary on d. 8, (...) then, it is not just helpful but necessary to see how he makes use of doctrines coming from the Metaphysics of Avicenna’s Book of Healing. So we look first at Aquinas’s source texts in Avicenna, and then at how he makes use of them in his commentary on the Sentences, Bk. 1, d. 8. (shrink)

This book of fifteen essays is presented in honor of one of the premier historians of medieval philosophy, Armand Maurer of the Pontifical Institute for Mediaeval Studies and the University of Toronto. The authors, internationally recognized scholars in the field of medieval philosophy and theology, are friends, colleagues, and students of Fr. Maurer. They are united in a common love of medieval thought and a common appreciation of philosophizing through the study of the history of philosophy. Their interests and methodologies, (...) however, are diverse, and cover a range from Justin Marytr, who died during the reign of Marcus Aurelius, to Bartholomew Mastrius, a contemporary of Descartes. “This is a volume that honors the memory of Armand Maurer not only by reviewing his own scholarly achievements but by advancing the state of scholarship on the subject that he loved, the philosophy of the middle ages. The range of topics covered here richly reflect the pluralism of medieval thought. Some of the essays gathered for this collection give a fresh look at important perennial themes like the nature of Christian philosophy and the real distinction between essence and existence. Others turn—as Maurer loved to do—to figures who are studied less often that help fill out our knowledge of this period and add to our sense of the contributions that study of medieval authors can make for contemporary philosophizing.” —Joseph W. Koterski, S.J., Fordham University “This lovely Festschrift for Armand Maurer contains fourteen essays by distinguished scholars on the tradition of medieval philosophy, from its ancient origins to seventeenth-century inheritors. Since many essays treat large-scale movements or fundamental issues, the volume will be useful to serious undergraduates and graduate students, as well as to scholars._ Laudemus_ indeed: from the editor’s moving tribute to Armand Maurer, through discussions of Avicenna and Thomas and Ockham, to Maurer’s closing recollections of his teachers, this volume is full of well-earned praise.” —Donald Morrison, Rice University.

While the importance of Avicenna as a source of Aquinas’s thought is generally recognized, the details of that dependence are just now being worked out. This article presents Avicenna’s teaching on the “subjects” of the theoretical sciences—physics, mathematics, and metaphysics—as presented in his Introduction to the Book of Healing. Its influence on Aquinas’s commentary on Boethius’s De trinitate, q. 5, art. 1, is then presented. Comparing Avicenna with Thomas in this way shows the profound influence of Avicenna on Thomas’s understanding (...) of the range of the three kinds of theoretical sciences. (shrink)

Appropriate philosophical language for describing the nature of God took almost two millennia to develop. Parmenides first discovered the language of being. Plato then distinguished the world of changing beings from the world of true being and also from the good “beyond being.” He refused to use being language for the Olympic gods. Aristotle understood a god as a substance (oujsiva). Avicenna described God, not as a substance but as “being,” which transcends thecategories, including substance. For Br. Thomas of Aquino, (...) God was no longer an Aristotelian substance, nor even an Avicennian “necessary being,” but is bestdescribed as “subsistent being itself ” (ipsum esse subsistens). Here the Christian disciple brought to an even higher level of perfection the achievements of his Islamic master, achievements that far surpassed their beginnings in Parmenidean monism. (shrink)

The development of virtue ethics in the contemporary philosophical world, as a reaction to various forms of consequentialism, deontology, and moral skepticism, has now brought forth translators determined to offer the wisdom of pre-moderns to contemporary readers. Here is a “small work” of Denis , the “last of the scholastics” and a contemporary of humanists like Ficino and Erasmus, who opened the modern age that is now rapidly closing. Educated in “the way of Thomas Aquinas” at the University of Cologne, (...) the Carthusian cloister allowed him leisure to become a prolific author, often cited by Catholics during the Protestant Reformation.He should be rescued from obscurity, for here he weaves together the vices and virtues in a way that eluded even Aquinas. In the spirit of the age, his audience was the ordinary layman. Denis brought Thomistic materials together with Scripture and the Fathers, using the Neoplatonic circle made famous by his namesake, Dionysius the Areopagite. Book One charts how sin pushes us ever deeper through the seven deadly sins. Then Book Two follows the workings of grace and nature in producing progress in virtue. Especially insightful is the way Denis uses Plotinus to. (shrink)

The theme of this series is given a human touch in Medieval Masters. All of the contributors in this memorial volume are paying tribute to their mentor, former University of Toronto (St. Michael's College) professor, Rev. Edward A. Synan. These essays provide ample proof that Synan's legacy of excellence will continue to influence students of philosophy for decades to come. In addition to ten essays, the volume contains a Synan bibliography and a very heartfelt opening remembrance from M. Jean Kitchel. (...) The essays are wide ranging, exploring Bonaventure, John Duns Scotus, Averroes, and Albert the Great, as well as the Thomistic themes of essence and existence; creation, numbers, and natures; and friendship and Christology. There is also a discussion of the treatment of the problem of universals in Boethius, Porphyry, and Abelard. Anyone who studies philosophy, whether a Thomist or not, will find this a valuable volume. That is as much a tribute to Father Synan as it is to the contributors, who were the grateful recipients of his generous and sage teaching. (shrink)
