Aquinas: Works

Is there a good argument for God’s existence? In his theology textbook for beginners, the Summa Theologiae, Thomas Aquinas provides five arguments in defense of belief in God: the Argument from Motion, the Argument from Causality, the Argument from Dependence, the Argument from Perfection, and the Argument from Design. As the titles of the arguments suggest, Aquinas uses various observations about motion, causality, design and other phenomena as evidence for the existence of the divine. This article examines these five arguments (...) in detail and considers what precisely Aquinas meant to demonstrate in each argument, along with their potential scope and limits. (shrink)

Thomas Aquinas was an Italian Dominican priest, philosopher, theologian, saint, and doctor of the Roman Catholic Church, famous for synthesizing the thought of Aristotle and Christian doctrine. His most important and well-known work is his Summa Theologiae. Here we will be reading from Aquinas’s other summa, the Summa Contra Gentiles. We will be taking a look at some of the early chapters of Book I in which he discusses the relationship between faith and reason. According to Aquinas, there are two (...) ways of coming to know truths about God: by reason and by faith through revelation. Aquinas thinks that both reason and faith are reliable and authoritative. He thinks that there are good reasons to expect that there would be truths of both sorts. And, finally, he thinks that, as a matter of principle, the truths of one can never really contradict the truths of the other. (shrink)

This present article examines an argument in Aquinas’s De potentia, q. 3, a. 9, in which Aquinas argues that the human soul must be created by God. After introducing the relevance of the problem and discussing the state of the literature, I lay out Aquinas’s argument and defend it by appealing to his broader metaphysical commitments. I then turn to two difficulties raised in the literature by B.C. Bazan and Lawrence Joseph Kaiser. Bazan argues that Aquinas’s claim that the human (...) soul must be created by God leads to internal inconsistencies within Aquinas’s metaphysical system. While not explicitly criticizing Aquinas, Kaiser’s account of the eduction of forms from matter also raises a few problems for the consistency of Aquinas’s claim. In response to Bazan and Kaiser, I argue that a firm grasp of Aquinas’s semantics dissolves the criticisms. (shrink)

The goal of this paper is to show that Thomas Aquinas, in his _Disputed Questions on Evil_, presents a theory of free will that is compatibilist but still involves a version of the principle of alternative possibilities (PAP) and even requires alternative possibilities for a certain kind of responsibility. In Aquinas’ view, choosing between possibilities is not the primary power of the will. Rather, choice arises through the complex interaction of various parts of human psychology, in particular through the indeterminacy (...) of the intellect and through the interaction between reason and passion. Both of these ways provide cases where Aquinas not only allows for alternative possibilities but thinks that they are necessary for moral responsibility, all the while remaining, strictly speaking, a compatibilist.

Le Commentaire du Traité de l'âme d'Aristote par Thomas d'Aquin est le cinquième des commentaires fondamentaux des oeuvres d'Aristote traduits en langue française. Avec celui des Physiques, de la Métaphysique, de l'Interprétation et des Analytiques, il fonde l'édifice de la philosophie de Thomas d'Aquin et assure les contreforts de sa théologie. Ce traité se présente comme un vaste essai de définition de l'âme et principalement de l'âme humaine, avec en filigrane, une question lancinante : cette âme est-elle immortelle? Si ce (...) traité est l'un des plus courts d'Aristote, et selon ses propres termes, encore à l'état d'ébauche, il est construit avec une rigueur méthodologique qui en fait une sorte de modèle pour toute réflexion philosophique. Thomas propose une explication reconnue comme des plus limpides, et introduit à un livre encore loué deux millénaires plus tard par Hegel, Marx ou Darwin. Comme le reste de l'oeuvre d'Aristote, il connaît aujourd'hui un regain d'intérêt remarquable et le commentaire de Thomas offre un guide très sûr pour son intelligence. (shrink)
