Aquinas: Philosophy of Mind

The coherence objection to the doctrine of the Incarnation maintains that it is impossible for one individual to have both the attributes of God and the attributes of a human being. This article examines Thomas Aquinas’s answer to this objection. I challenge the dominant, mereological interpretation of Aquinas’s position and, in light of this challenge, develop and defend a new alternative interpretation of Aquinas’s response to this important objection to Christian doctrine.

This article develops an argument in defense of the claim that Aquinas holds that there are some kinds of activities which can be performed only by persons. In particular, it is argued that Aquinas holds that only persons can engage in the activities proper to a rational nature, e.g., the activities of intellect and will. Next, the article turns to discuss two implications of this thesis concerning Aquinas’s concept of a person. First, the thesis can be used to resolve a (...) prominent scholarly debate concerning Aquinas’s views on the possibility of human persons surviving their bodily deaths. Second, it also points to a problem with a leading interpretation of Aquinas’ account of the Christian doctrine of the Incarnation. Finally, the article concludes by discussing how a correct interpretation of Aquinas’s views on these matters is related to a broader scholarly debate concerning the history of the Western concept of a person.

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)

In his paper, “Mersenne’s Principles of Song Creation,” Eric Wilkinson (2023) lists several aims he intends to establish. I will confine my comments to two areas only: First, on the reasons given for preferring Aquinas’s theory of the passions as the major influence on Mersenne to those of either Aristotle or Cicero, and Second, on its representation of Aquinas’s theory of the passions.

q. 16 of John of Naples’ Quodlibet III – Utrum dolor vel passio damnatae animae separatae sit, sicut in subiecto immediato, in eius essentia vel potentia – evokes one of the most delicate debates, both from a theological and philosophical point of view, of scholastic eschatology between the end of the 13th century and the first decades of the 14th: that relating to the action of hellfire (considered, due to the auctoritas of Gregory the Great, corporeal and identical in essence (...) to sublunar fire) on an immaterial reality such as the soul in its state of separation (i.e. in the period between the individual death and the final judgement). The article retraces the way in which (in the well-known q. 2 of Quodlibet VI) John of Naples defends Thomas Aquinas from the suspicion of incurring, with his position, the condemnations of Tempier in 1270 and 1277, and how Aquinas himself tries to explain (especially in q. 26 of his Quaestiones disputatae de veritate) the passio or pain of the soul (both in the state of separation and in that of conjunction), through the double distinction between passio corporalis and passio animalis, and, within the former, between laesio and experimentalis perceptio laesionis. It then analyses q. 16 of Quodlibet III, in which John of Naples identifies the rational appetite – i.e. the will – as the immediate subject of the separate soul’s pain. In the appendix, an edition of John’s question is provided on the basis of the manuscripts Napoli, Biblioteca Nazionale, VII.B. 28 (= N) and Tortosa, Biblioteca de la Catedral, 244 (= T). (shrink)

In this review of Dominik Perler’s book Eine Person sein, Perler’s reconstruction of the relationship between Thomas Aquinas’s unitarist position and his theory of incontinence is analyzed. Perler argues that the unitarist position of Thomas allowes him to conceive of incontinence as a weakness of the whole psychological system of the person. Unlike the mad person, the incontinent has responsibility because she has preserved a degree of rational control. Perler argues that the incontinent person is not responsible for the spontaneous (...) emergence of desire, which is a natural process, only for the way in which she rationally controls it (or not). By analyzing Aquinas’s notion of naturality with respect to desires, I argue that the person is actually responsible for the emergence of a desire, just in case the content of the desire is constituted by a rational choice of end.

In the Summa Theologiae, Thomas Aquinas states that the “aspect of pastness” involved in memory is a certain kind of cognitive object — i.e., an intention — apprehended by the “estimative power.” All told, however, Aquinas mentions this idea precisely once. In this article, I construct an account of the idea that pastness is an estimative intention by drawing upon texts in which I argue that Aquinas develops this idea, albeit without invoking the terminology of the estimative intention. I conclude (...) that, by identifying the aspect of pastness as an estimative intention, Aquinas neatly synthesizes the Aristotelian and Arabic traditions on memory. (shrink)

Kant’s subject as source of universality and necessity in human understanding is Modern Philosophy's solution to the old problem of the universals, a solution which appeared to supersede once and for all the Aristotelian theory of abstraction. The present paper intends to show how Aquinas's Aristotelian doctrine on abstraction may stand the Kantian challenge and resolve the old problem when three principles are brought into play: 1) the same perfection can subsist in two different modes of being, and thus the (...) universal content of knowledge can be present in the particular reality (Summa, I, 84, 1); 2) things which are really distinct between themselves can be known in their distinction, even when they cannot exist separately (metaphysical distinction justifies gnoseological separation); 3) as Cornelio Fabro suggests, it is artificial to separate in the object of experience the object’s different levels of objectivity (quality, configuration and meaning) and, as a result, human experience could be considered the source not only of sensible content but also of intelligible content. This “defense” of Thomistic abstraction intends to offer an account of knowledge which reunites again epistemology with common sense experience, so that philosophy may no longer be a Platonic abstraction but a meaningful explanation of life.

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.

In recent years, a large amount of scholarship has been written about St Thomas Aquinas's views on free will and determinism. This paper is an attempt to bring some Thomist views of libertarian free will into dialogue with analytic philosopher Peter van Inwagen and his ‘mysterianism’ about free will. The thesis of this paper is that Thomist libertarians about free will are committed to Peter van Inwagen's mysterianism about free will. The paper intends to accomplish this aim by showing how (...) recent accounts of Thomist libertarianism cannot defeat the intuitive strength of van Inwagen's ‘Replay argument’. The significance of this conclusion is that some Thomists are committed to mysterianism and that mysterianism is a legitimate position a Thomist can hold. This also provides evidence that the Thomist tradition can grow and be nourished by engagement with contemporary analytic philosophy. (shrink)

Historians have claimed that the two closely related concepts of animism and natural teleology were both decisively rejected in the Scientific Revolution. They tout Robert Boyle as an early modern warden against pre-modern animism. Discussing Avicenna, Aquinas, and Buridan, as well as Renaissance psychology, I instead suggest that teleology went through a slow and uneven process of rationalization. As Neoplatonic theology gained influence over Aristotelian natural philosophy, the meaning of animism likewise grew obscure. Boyle, as some historians have shown, exemplifies (...) this uneven process. There is an unresolved tension between his religious convictions and the implicit animism of his empirical practice.
