Aquinas’s process of abstraction of the particular thing into a universal concept is of pivotal importance for grounding his philosophy and theology in a natural framework. Much has been said and written regarding Aquinas’s doctrine of abstraction, yet recent studies still consider it to be ‘nothing more than a kind of magic.’ This problematic claim is not without foundation, for in trying to understand exactly how this process works, we are constantly faced with an unbridgeable abyss and the (...) repeated vague explanations made by Aquinas. The plain truth is that Aquinas explains what abstraction ought to do and yet, most of the time, he does not explain how it is to be done. This paper intends to show that although Aquinas does not present us with a mechanism for the theory of abstraction, we are nevertheless able to construct a viable mechanism which accords with Aquinas’s guidelines. The aim of constructing a working mechanism that corresponds to what Aquinas demands of the process of abstraction is twofold: First, it attempts to extricate Aquinas’s doctrine of abstraction from the claims of being a quasi-natural doctrine. Second, a viable process of abstraction which is derived from Aquinian-Aristotelian sources can approach contemporary cognitive problems from a fresh point of view. (shrink)

General remarks on some ontological premises of Aquinas' Epistemology.

In Aquinas's account of the beatific vision, human beings are joined to God in a never-ending act of contemplation of the divine essence: a state which utterly fulfills the human drive for knowledge and satisfies every desire of the human heart. In this paper, I argue that this state represents less a fulfillment of human nature, however, than a transcendence of that nature. Furthermore, what’s transcended is not incidental on a metaphysical, epistemological, or moral level.

I discuss what Aquinas’ doctrine of divine simplicity is, and what he takes to be its implications. I also discuss the extent to which Aquinas succeeds in motivating and defending those implications.

From the early reception of Thomas Aquinas up to the present, many have interpreted his theory of liberum arbitrium to imply intellectual determinism: we do not control our choices, because we do not control the practical judgments that cause our choices. In this paper we argue instead that he rejects determinism in general and intellectual determinism in particular, which would effectively destroy liberum arbitrium as he conceives of it. We clarify that for Aquinas moral responsibility presupposes liberum arbitrium (...) and thus the ability to do otherwise, although the ability to do otherwise applies differently to praise and blame. His argument against intellectual determinism is not straightforward, but we construct it by analogy to his arguments against other deterministic threats. The non-determinism of the intellect’s causality with respect to the will results from his claims that practical reasoning is defeasible and that the reasons for actions are not contrastive reasons.

In this paper I argue that Aquinas’ account of analogy provides resources for resolving the prima facie conflict between his claims that (1) the divine relations constituting the persons are “one and the same” with the divine essence; (2) the divine persons are really distinct, (3) the divine essence is absolutely simple. Specifically, I argue that Aquinas adopts an analogical understanding of the concepts of being and unity, and that these concepts are implicit in his formulation of claims (...) about substance and relation in the Trinity. I then show how Aquinas appeals to key structural features of analogical concepts, notably, the simpliciter/secundum quid characterization, to resolve apparent conflicts between the unity of substance and distinction of relations in the Trinity.

Attempts to solve the issue of divine action in nature have resulted in many innovative proposals seeking to explain how God can act within nature without disrupting the created order but introducing novelty in the history of the universe. My goal is to show how Aquinas' doctrine of providence, mainly as expressed in his De Potentia Dei, fulfils the criteria for an account of divine action: that God's action is providential in the sense that God is involved in the (...) individual and particular here and now. -/- .

Aquinas’ theory of being has received a growing amount of attention from contemporary scholars, both from a historic and a philosophical point of view. An important source of this attention is Geach’s seminal Form and Existence. In it, Geach argues that Aquinas subscribes to a tensed notion of existence and a theory of time according to which past and future entities do not exist in act. Subsequent commentators, such as Kenny in his Aquinas on Being, have agreed (...) with Geach on both points. In this paper, I argue that in several passages of his corpus, most notably those in which he is concerned with God’s knowledge of future contingents, Aquinas implicitly subscribes to a theory of being and time according to which: past and future entities are attributed existence in act, there is theoretical need for introducing a tenseless notion of existence.

Joseph Hannon has expressed a most surprising objection to Aquinas scholar Prof William E. Carroll in his latest paper “Theological Objections to a Metaphysicalist Interpretation of Creation.” The main claim is that Prof. Carroll misunderstands Aquinas' doctrine of creatio ex nihilo by reducing it to a metaphysical notion, rather than considering it in its full theological sense. In this paper I show Hannon's misinterpretation of Carroll's and Thomas Aquinas' thought, particularly by stressing the dependence that the doctrine (...) of providence through secondary causes has on the doctrine of creatio ex nihilo.

In the Aristotelian tradition, there are two broad answers to the basic question "What is soul?" On the one hand, the soul can be described by what it does. From this perspective, the soul seems to be composed of various different parts or powers (potentiae) that are the principles of its various actions. On the other hand, the soul seems to be something different, namely, the actual formal principle making embodied living substances to be the kinds of things that they (...) are. Contemporary Aristotelians are split on how to interpret Aristotle: Anna Marmodoro (2013, 18), Thomas Johansen (2012, 81), and most others argue that the soul is nothing but a kind of cluster or group of powers. Rebekah Johnston (2011), however, strongly disagrees and argues that the soul is only the actual principle of embodied substance. Aquinas provides a novel and neglected solution to this problem and would argue that both sides are partly right but that either side is insufficient without the other. (shrink)

This essay explores some of the central aspects of Aquinas's account of mental representation, focusing in particular on his views about the intentionality of concepts (or intelligible species). It begins by demonstrating the need for a new interpretation of his account, showing in particular that the standard interpretations all face insurmountable textual difficulties. It then develops the needed alternative and explains how it avoids the sorts of problems plaguing the standard interpretations. Finally, it draws out the implications of this (...) interpretation with the aim of correcting some persistent misunderstandings of the connection between Aquinas's views and those developed by contemporary philosophers of mind.

I defend a solution to the puzzle of petitionary prayer based on some ideas of Aquinas, Gregory the Great, and contemporary desert theorists. I then address a series of objections. Along the way broader issues about the nature of desert, what is required for an action to have a point, and what is required for a puzzle to have a solution are discussed.

[Encyclopedia entry] Born in Italy in 1225, and despite a relatively short career that ended around 50 years later in 1274, Thomas Aquinas went on to become one of the most influential medieval thinkers on political and legal questions. Aquinas was educated at both Cologne and Paris, later taking up (after some controversy) a chair as regent master in theology at the University of Paris, where he taught during two separate periods (1256-1259, 1269-1272). In the intermediate period he (...) helped establish a studium for his Order in Rome, beginning work on the Summa Theologiae, the masterwork for which he is still well-known. Subsequent to an experience (traditionally, a vision) Aquinas had on the feast of St. Nicholas in 1273, Aquinas intentionally refrained from further work on that text, so that it remained incomplete at the time of his death a year later in 1274. Apart from his own contributions, the Thomistic school – including followers within and without the Dominican Order to which Aquinas belonged – has had profound and far-reaching influence upon the history of legal thought in the West. Many of the classical developments of Thomistic thought are written as commentaries on the Summa Theologiae (hereafter, ST), including the works of Tomasso de Vio (Cajetan) and those of Domingo Banez, Francisco de Vitoria, Bartholome de las Casas, and the other highly influential members of the School of Salamanca who are noteworthy for developing Aquinas’ political and legal thought in the 16th century. Specifically, the ways in which Aquinas synthesized classical political and legal themes around the law, morality, and the common good provided a touchstone for what has come to be called ‘natural law jurisprudence.’ Natural law thinkers, in short, appeal to objective facts about what is good for human beings, and the social or political nature of the kind of creatures that we are, as a standard against which we measure the legal and social institutions created by human institutions. What is crucial here is that facts about human beings as social animals constitute reasons for individuals and groups to act or be structured in certain ways, such that ‘nature’ is the proper source for jurisprudential and political principles.

Defining the capital vice of sloth (acedia) is a difficult business in Thomas Aquinas and in the Christian tradition of thought from which he draws his account. In this article, I will raise three problems for interpreting Aquinas's account of sloth. They are all related, as are the resolutions to them I will offer. The three problems can be framed as questions: How, on Aquinas's account, can sloth consistently be categorized as, first, a capital vice and, second, (...) a spiritual vice? These two questions lead to a third, namely, how is the condition of sloth possible, given Aquinas's moral psychology and the nature of the will? The resolution of these interpretive issues can help do two things. It can help explain the apparent inconsistency between traditional (ancient and medieval) and contemporary conceptions of this vice, and —if Aquinas's account is right— it can help us diagnose contemporary moral and spiritual maladies that may either go unnoticed or be confused with distinctively modern "virtues" like diligence and industriousness.

As I read the texts of Aquinas and the state of the discussion among his interpreters on the question of the compatibility between creaturely freedom and divine providence, an alternative interpretation suggests itself. My impression is that traditional interpreters left Aquinas’ account of the relationships among human freedom, providence and divine goodness inadequately defended, while Maritain and Lonergan with fair intention subverted it, because their readings were hampered by libertarian intuitions about human freedom which Aquinas did not (...) share. -/- Understanding Aquinas’ account of freedom in compatibilist terms reveals greater coherence in his account of the nature of human freedom and the role our freedom plays in the created order than do accounts infected with libertarian notions of freedom. Once the compatibilist conception of freedom is comprehended, it functions like a lens of superior clarity through which other aspects of Aquinas’ thought concerning the created order can be seen afresh. Accordingly, our first task is to craft the lens itself: a compatibilist conception of freedom will be ground from the material available in Aquinas’ writing on the will, its acts, and their causes in a way unclouded by the apparent tensions between causality and freedom which libertarian intuitions introduce. Then grasping the compatibilist lens, we will see through it a coherent account of the high purpose in the plan of providence for free creatures. Finally, we will observe coherence in Aquinas’ account of the permission of sin and even the ultimate failure of free creatures through the perspective afforded by compatibilist freedom. (shrink)

Aquinas's account of law as an ordering of reason for the common good of a community depends on the mereology that covered his theory of parthood relations, including the relations of parts to parts and parts to wholes. Aquinas argued that 'all who are included in a community stand in relation to that community as parts to a whole', and 'every individual person is compared to the whole community as part to whole'. Aquinas held that the perfection (...) of wholes through the proper ordering of their parts does not entail the elimination of diversity, but in many cases requires diversity. Aquinas argued that there are two ways of ordering parts within a whole. Firstly, the parts are ordered with respect to one another, and secondly, the parts are ordered toward an end. The ordering of a whole's parts to one another is always for the sake of the ordering of the whole to its extrinsic end. Aquinas argued that the good toward which the law directs a community is called the 'common good' of that community. The common good or common end toward which members of a community are ordered can be the sort of end that the agents bring into existence through their own actions such as justice within a community, or the sort of end that can exist apart from the actions of the agents.

The purpose of this essay is to explore, and clarify, some key features in Aquinas’ account of the virtue of temperance, with an eye to answering some common objections raised against a positive evaluation of temperance. In particular, I consider three features of Aquinas’ understanding of temperance: First, the role of the rational mean in temperance; second, the role of rightly ordered passions in temperance; and third, the ‘despotic’ control of reason over the passions in temperance. Along the (...) way I consider three common objections to Aquinas’ account of temperance: the objection that temperance can be misused for evil, the objection that temperance devalues effort, and the objection that temperance devalues strong passions and thereby implicitly devalues the goodness of sexuality. In responding to these objections on behalf of Aquinas, I take the opportunity to clarify and slightly extend Aquinas’ account of temperance. (shrink)

While Aquinas’s primary notion of truth as adequation is applied to God and man in somewhat different ways, it is apparent that it is not applicable to the angels, at least not in the same way. However, since truth is a transcendental, and as transcendentals are convertible, one may claim that the transcendental systems that apply to various beings differ. In order to consolidate the universality of the transcendental system, the study aims to show the manner truth as adequation (...) can be applied to the angels. (shrink)

Aquinas’s analyses of akrasia can be divided into two: the discussions in his theological works and his Ethics commentary. The latter has sometimes been regarded as merely repetitive of Aristotle and unrepresentative of Aquinas’s own thoughts. As such, little attention has been paid to the specific, and sometimes significant, differences between the two treatments and to what those differences might mean. This paper remedies this situation by focusing on four such differences. I ultimately provide rationales for these differences, (...) thereby arguing for the consistency of the two treatments and the importance of consulting Aquinas’s Ethics commentary to gain a full appreciation of his view of akrasia. Using this strategy, the paper concludes with a controversial suggestion regarding the structure of the weak akratic’s reasoning. (shrink)

This paper seeks to articulate the relationship between medieval logic and theology. Reviewing modern scholarship, we find that the purpose of medieval logic, when it is even inquired about, has proven difficult to articulate without reference to theology. This prompts reflection on the metaphors of logic as a “tool” and a “game”: a tool is not merely instrumental, insofar as it can have its own intrinsic goods and can shape and be shaped by that which it serves; likewise a game, (...) with its own intrinsic goods, may yet contribute to extrinsic goods as well. After reviewing some distinctive ways in which theology shaped developments of medieval logic, this paper summarizes key examples from the work of Thomas Aquinas where medieval logic shaped the articulation of, and is therefore crucial to a proper understanding of, theological arguments and claims. The conclusion suggests implications for future philosophical and theological work. (shrink)

I defend my paper “Aquinas, Geach, and Existence”[1]against objections from Luca Gili, who argued that, according to Aquinas, future contingents do not enjoy genuine existence but exist in God’s mind only.[1] Damiano Costa, “Aquinas, Geach, and existence”, European Journal for Philosophy of Religion 11, no. 3.

Most philosophers in the High Middle Ages agreed that what we immediately perceive are external objects. Yet most philosophers in the High Middle Ages also held, following Aristotle, that perception is a process wherein the perceiver takes on the form or likeness of the external object. This form or likeness — called a species — is a representation by means of which we immediately perceive the external object. Thomas Aquinas defended this thesis in one form, and Durand of St.-Pourçain, (...) his Dominican successor, rejects it. This paper explores Durand's novel criticism of Aquinas's species-theory of cognition. I first develop and defend a new interpretation of Durand's central criticism of Aquinas's theory of cognition. I close with some considerations about Durand's alternative to the theory. -/- . (shrink)

Amidst the broad divergence in opinion of philosophers and scientists at understanding reality that has lent character to the historical epochs of the Philosophical enterprise, the crucial realization has always been, of the necessity of Epistemology in our entire program of making inquiry into ‘What Is’. This realization seems born out of the erstwhile problem of knowing. Epistemology, which investigates the nature, sources, limitations and validating of knowledge, offers a striking challenge here. Since we have no direct access to our (...) world around us, outside of the subjective experience offered us by our senses, we are handicapped at making comparisons of our beliefs with a concrete world, out there, or with elements of the world. Our statements about the world seem to stand alone, buffeted against the intimidating tide of possible contradicting circumstances. Our putative claims to knowledge, therefore, face the exigency of justification. Ayer, expressing the urgency of resolving this persisting lacuna, provides an alternative criterion of knowing, as ‘having the right to be sure’. Thus, it is this deep-seated concern that has evolved, over time, to become the primary thrust of the project of Epistemology, raising the controversy over which, of Epistemology or Metaphysics, is to be accorded the prime status of first philosophy. However, Aquinas is wise to build his epistemological premise on a firm metaphysical support, clarifying the needed development from being to knowledge. For, being has to first exist to constitute the object of perception, belief, and knowledge. Accordingly, our exposition of Aquinas’ epistemology will first take a cursory look at the theoretical and historical background to Aquinas’ Philosophy, before offering a general characterization of his theory of knowledge. Then, the paper will discuss his concept of sense perception as a basis for all knowing, followed closely by an analysis of cognition and Scientia. (shrink)

Thomas Aquinas and Mulla Sadra both criticized the previous theories on the soul-body problem, which held that the body is a mere instrument in the employ of the soul. Instead, they, following Aristotle, regard the connection between the soul and the body as form and matter since, they thought of it as an essential connection not accidental. Despite this initial similarity there are differences between Aquinas and Sadra on this problem which in the end lead them to two (...) distinctive results. (shrink)

This paper compares Aristotle’s and Aquinas’s accounts of the virtue of magnanimity specifically as a corrective to the vice of pusillanimity. After definingpusillanimity and underscoring key features of Aristotelian magnanimity, I explain how Aquinas’s account of Christian magnanimity, by making humandependence on God fundamental to this virtue, not only clarifies the differences between the vice of pusillanimity and the virtue of humility, but also showswhy only Christian magnanimity can free us from improper and damaging forms of dependence on (...) the opinions and standards of others, enabling us toavoid the moral pitfalls of both pusillanimity and presumption.

In contemporary positive law there are legal institutions, such as conscientious objection in the context of military service or “conscience clauses” in medical law, which for the sake of respect for judgments of conscience aim at restricting legal obligations. Such restrictions are postulated to protect human freedom in general. On the basis of Thomas Aquinas’ philosophy, it shall be argued that human dignity, understood as the existential perfection of a human being based on special unity, provides a foundation for (...) imposing limitations on the scope of legal obligations in general. Human freedom plays a crucial role in understanding dignity as perfection based on the special individuality of a personal being, which in turn is based on the free choice to pursue a unique way of life. Therefore, Aquinas’ argumentation is, at its core, liberal – the perfection rather than the imperfection of a human being underlies the requirement to limit legal obligations. Dignity understood as the special unity of a person also provides the basis for limiting obligations in the case of conscientious objection; however, in that case, such limitations aim at safeguarding internal integrity rather than the individualisation of a given way of life. _This project was financed with funds from the National Science Centre allocated on the basis of the decision number DEC-2013/09/B/HS5/04232._.

In this chapter I seek to examine the credibility of Finnis’s basic stance on Aquinas that while many neo-Thomists are meta-ethically naturalistic in their understanding of natural law theory (for example, Heinrich Rommen, Henry Veatch, Ralph McInerny, Russell Hittinger, Benedict Ashley and Anthony Lisska), Aquinas’s own meta-ethical framework avoids the “pitfall” of naturalism. On examination, the short of it is that I find Finnis’s account (while adroit) wanting in the interpretation stakes vis-à-vis other accounts of Aquinas’s meta-ethical (...) foundationalism. I think that the neo-Thomists are basically right to argue that for Aquinas we cannot really understand objective truths about moral standards unless we derive them from our intellective knowledge of natural facts as given to us by the essential human nature that we have. While I find Finnis’s interpretative position on Aquinas wanting, I go on to argue that his own attachment to non-naturalism is justified and should not be jettisoned. Because I think non-naturalism important to the future tenability of a viable natural law ethics (an ethics that is both cognitive and objectivist), I argue that Finnis should, so to speak, “beef up” his “fundamental option” for non-naturalism and more fully avail himself of certain argumentative strategies available in its defense, argumentative strategies that are inspired by the analytical philosophy of G.E. Moore. (shrink)

Cajetan’s analogy theory is usually evaluated in terms of its fidelity to the teachings of Aquinas. But what if Cajetan was trying to answer questions Aquinashimself did not raise, and so could not help to answer? Cajetan’s De Nominum Analogia can be interpreted as intending to solve a particular semantic problem: to characterize the unity of the analogical concept, so as to defend the possibility of a non-univocal term’s mediating syllogistic reasoning. Aquinas offers various semantic characterizations of analogy, (...) saying it involves, for instance: signification per prius et posterius; or a ratio propria which is only found in one analogate; or diverse modi significandi with a common res significata. Examined in turn, it is clear that none of Aquinas’s rules for analogy solve the semantic problem described. Cajetan thus cannot be reasonably expected to have intended his analogy treatise primarily as an interpretation or systematization of Aquinas’s teaching on analogy. (shrink)

The main goal of this paper is tocompare how Thomas Aquinas expressedhis doctrine of providence through second-ary causes, making use of both Aristotelianand Neo-Platonic principles, in the seventharticle of the third question of his Quaes-tiones Disputatae De Potentia Dei and his Super Librum de Causis Expositio , in whichhe intends to solve the problem of themetaphysical mechanism by which God providentially guides creation. I will rst present his arguments as they appear inthe disputed questions, followed by a pre-sentation of (...) his thought on the matter inhis commentary of the Liber de Causis , andconcluding with my comparative analysisof Aquinas’ solution to the issue of God’sprovidential activity in nature.

Aquinas’s actual response to a naturalistic challenge at ST I.2.3 is one which most naturalists would find unimpressive. However, I shall argue that there is a stronger response latent in his philosophical system. I take Quine as an example of a methodological naturalist, examine the roots of his position and look at two critical responses to his views (those of BonJour and Boghossian). If one adjusts some of the problematical aspects of their responses and establishes a hybrid position on (...) the epistemology and metaphysics of an antinaturalistic stance, it turns out to be the position Aquinas himself takes on meaning and knowledge.

Christine Overall has argued that miracles, if they exist, would be an evil committed by God and therefore disprove the existence of God. However, her notion of a miracle as an intervention presupposes a view about the relation between God and creation that posits God as an ‘outsider.’ Such a view has not been held by all theists. It was not held by Thomas Aquinas. I show that Aquinas ’s conception is not susceptible to Overall’s criticisms. The upshot (...) is that theists should avoid any view of God as an ‘outsider,’ if they wish to avoid Overall’s criticisms. (shrink)

Many Christians seem to have difficulty in their worldview insofar as they affirm: (1) If a person cannot do something, then that person is not blameworthy for not doing that action, (2) No one has it within his or her power to acquire faith, and (3) Some individuals who do not have the virtue of faith are nevertheless blameworthy for not having faith. These propositions together appear to entail a contradiction. In this paper I show how the Christian philosopher, St. (...) Thomas Aquinas, affirms these propositions but avoids the contradiction because of his understanding of faith, blame, and grace. (shrink)

Identity-Over-Time has been a favorite subject in the literature concerning Thomas Aquinas. Aquinas addresses this issue in many discussions, including especially the identity of material things and artifacts, the identity of the human soul after the corruption of body, the identity of the body of Christ in the three days from his death to his resurrection and the identity of the resurrected human body at the end of time. All these discussions have a point in common: they lead (...) Aquinas to raise the question of Identity-Over-Time with respect to things that fully exist in act, i.e., things that possess an identity of their own and change some of their parts or properties over time while continuing to be what they are. In this article, I investigate this topic from a different angle, considering the case of the trans-temporal identity of things that do not yet have an identity of their own or fully exist in act. The case at stake is that of the identity of the human embryo through the process of human generation. It is a puzzle that Aquinas seems to have some difficulties to solving, given his account of human embryogenesis as a process that alternates generations and corruptions of the subject. At the same time, though, Aquinas does not want to renounce the idea that the subject of generation must be numerically one and the same throughout all the process. In order to solve this puzzle, Aquinas seems to suggest distinguishing the identity of the subject from the identity of its matter and/or form. At given conditions, a thing can even change its matter and form while continuing to be the same thing in number. Specifically, the numerical identity of the subject of generation is justified by the identity entailed by the metaphysical notions of potency and act. (shrink)

Several of Thomas Aquinas's proofs for the existence of God rely on the claim that causal series cannot proceed in infinitum. I argue that Aquinas has good reason to hold this claim given his conception of causation. Because he holds that effects are ontologically dependent on their causes, he holds that the relevant causal series are wholly derivative: the later members of such series serve as causes only insofar as they have been caused by and are effects of (...) the earlier members. Because the intermediate causes in such series possess causal powers only by deriving them from all the preceding causes, they need a first and non-derivative cause to serve as the source of their causal powers.

This essay contains an attempt to trace the evolution of the concept of wisdom as found in the thought of Aristotle and Aquinas in terms of how the philosophical concept of wisdom as an intellectual virtue is understood and used to express the theological concept of wisdom as a gift of the Holy Spirit. The main aim is to understand how Aquinas derived the concept of wisdom from Aristotle's metaphysics and developed it in his mysticism. This research is (...) based on a close study of Book Six of Aristotle's Nichomachean Ethics, the corresponding sections of Aquinas' Sententia libri Ethicorum and question forty-five of the second part of the second part of Aquinas' Summa Theologiae. The insights gained from the study are then used to decipher the theoretical meaning of Augustine's famous saying: "love and do what thou wilt" and to expound on the practical value of wisdom for religious leaders.

Although the question of whether, in the thought of Thomas Aquinas, sanctifying grace is “created” or “uncreated” has received considerable attention in the last several decades, many of the questions and arguments proposed by those, such as Karl Rahner, Jerome Ebacher, and A.N. Williams, in favor of grace being uncreated have gone unanswered. Among these ancillary questions and arguments are those concerning the proper subject of grace, the categorial classification of grace, and the reason for the mystery and unconsciousness (...) of grace. These questions appear unrelated, but, as this paper argues, they are each logically connected to each other and to the overall thesis that sanctifying grace is created, not uncreated. This paper aims to make Aquinas’s thesis that grace is created more palatable to objectors by addressing each of these previously unaddressed ancillary questions. (shrink)

The following is an interpretation of Aquinas’ agent intellect focusing on Summa Theologiae I, qq. 75-89, and proposing that the agent intellect is a metaphysical rather than a formal a priori of human understanding. A formal a priori is responsible for the intelligibility as content of the object of human understanding and is related to Kant’s epistemological views; whereas a metaphysical a priori is responsible for intelligibility as mode of being of this same object. We can find in (...) class='Hi'>Aquinas’ text many indications that the agent intellect is not productive of the universal as content but is, rather, productive of the abstracted or intelligible mode of being of the universal nature. This is because for Aquinas the universal nature, which is the object of human understanding, is present in the things themselves but with a different mode of being. Chapter 1 is intended to establish the fact which requires for Aquinas an agent intellect, and provides two very important principles: one is that the object of human understanding (the universal nature) is present in the things themselves and, the other, that it is not in the things themselves with a mode of being which makes it available to the intellectual eye. These two principles lead us to the main point of Chapter 2, namely the distinction between the intelligible object and its intelligible mode of being. Now, because knowing is receptive of the intelligible object (Chapter 3), which is present in the things themselves (Chapter 1), the agent intellect is productive not of the object’s intelligible content, but of its abstracted or intelligible mode of being (Chapter 4).

Divine simplicity is central to Thomas Aquinas’s philosophy of God. Most important for Aquinas is his view that God’s existence (esse) is identical to God’s essence; for everything other than God, there is a distinction between existence and essence. However, recent developments in analytic philosophy about the nature of existence threaten to undermine what Aquinas thought regarding divine simplicity. In the first chapter of this dissertation, I trace Aquinas’s thinking on divine simplicity through the various texts (...) he wrote regarding the matter. I establish that it is crucial for Aquinas that God is identical to his existence. But, is it even coherent to talk about “a thing’s existence?” In Chapter Two I summarize the arguments of C.J.F. Williams that existence is not a real property that individuals have and that predicating the word “exists” after the name of an individual produces linguistic gibberish. After considering, and rejecting, in Chapter Three attempts by some philosophers to refute Williams’s arguments, I turn, in Chapter Four, to a more detailed account of what Aquinas means by esse, the Latin word often rendered in English as “existence.” The conclusion that I come to is that Aquinas does not mean by esse what contemporary philosophers have usually meant by “existence.” Rather, he understands esse to be the act by which anything can be anything at all, instead of there being nothing whatsoever. In the final chapter, I turn to implications of this for Aquinas’s views of divine simplicity, showing that rather than being incoherent, Aquinas’s thinking on esse points toward the unfathomable mystery that is God.

Brian Leftow sets out to provide us with an account of Aquinas’s metaphysics of modality. Drawing on some important recent work, which is surely close to the spirit (if not quite the letter) of Aquinas’s thought, he frames his discussion in terms of “truthmakers”: what is it that makes true claims about possibility and necessity—that is to say, what serves as their ontological ground or ultimate metaphysical explanation? Leftow’s main thesis is that, for Aquinas, all true modal (...) claims are made true by one and the same thing—namely, God. Along the way, however, he also attempts to show that Aquinas’s endorsement of this thesis commits him to an objectionable form of Platonism about possible worlds. (shrink)

Arguably one of the most fundamental phase shifts that occurred in the intellectual history of Western culture involved the ontological reduction of secondary qualities to primary qualities. To say the least, this reduction worked to undermine the foundations undergirding Aristotelian thought in support of a scientific view of the world based strictly on an examination of the real—primary— qualities of things. In this essay, I identify the so-called “Causal Argument” for a reductive view of secondary qualities and seek to deflect (...) this challenge by deriving some plausible consequences that support a non-reductive view of secondary qualities from an Aristotelian view (via the philosophical commentary of Thomas Aquinas). Specifically, my argument has two facets. First, I show that Aristotle’s view both implies recognition of the extramental existence of secondary qualities and is a prima facia natural view to take regarding the ontology of secondary qualities. Second, I show that the Causal Argument, which is thought to undermine a natural view of secondary qualities as real things, loses its bite when one examines perception in light the ontological relationship among the categories of quality, quantity and substance.

Stump, Aquinas, and Dawkins & Company seem to think that objectual faith--"faith in"--is identical with propositional belief. I argue that they are wrong. More plausibly, objectual faith requires belief of the relevant proposition(s). There are other forms of faith: propositional faith, allegiant faith, and affective or global faith. We might conjecture that each of these forms of faith likewise require belief of the relevant propositions. More weakly, we might conjecture that at least one of them does. This latter thesis (...) I call the Stump-Aquinas-Dawkins Thesis (SAD). In this essay, I develop one reason against SAD and critique seven reasons for it. (shrink)

Aquinas’s account of the human soul is the key to his theory of human nature. The soul’s nature as the substantial form of the human body appears at times to be in tension with its nature as immaterial intellect, however, and nowhere is this tension more evident than in Aquinas’s discussion of the ‘separated’ soul. In this paper I use the Biblical story of the rich man and Lazarus (which Aquinas took to involve actual separated souls) to (...) highlight what I will call the Two-Person Problem facing his account of human identity through death and the bodily resurrection. Aquinas claims that the rational soul is neither the human being nor the human person. When the rich man’s soul says “I am in agony,” then, what is the referent of “I?” It appears that there is a human person, ‘Dives,’ who is replaced at Dives’s death by the person ‘Dives’s soul,’ who is in turn replaced at the bodily resurrection by ‘Dives,’ whom Aquinas claims is numerically identical to the original person. But this seems hopeless as an identity-preserving account of human nature. I believe that Aquinas’s account of human nature does not, as it stands, possess the resources with which to overcome this difficulty; I conclude that reconstructing a(n otherwise) Thomistic account that involves immediate bodily resurrection, although a radical approach, is the one best suited to preserving the most essential features of Aquinas’s theory.

Kant and Aquinas: who can doubt they are different? And however, there are some who equate Aquinas and Kant in doctrines in which they are actually opposed; some attribute to St. Thomas Aquinas approaches that are Kantian and by no means Thomistic. They make those mistakes by misinterpreting or misusing Aquinas’ texts. This paper intends to clarify a little bit the radical difference between the approaches of Aquinas and Kant to human knowledge. In my view, (...) we need first of all to understand the problem of the universals, which is the basic problem of human understanding and, in a sense, the only problem of philosophy. Second, we need to understand the stance of both philosophers in front of this same problem. Only then will we be able to see what and how radical is the difference between Aquinas and Kant.

Aquinas claims that ‘He Who Is’ is the most proper of the names we have for God. But this attempt to ‘describe’ God with a philosophical concept like ‘being’ can seem dangerously close to creating a false conception based on our limited understanding – an idol. A dominant criticism of Aquinas’ use of this term is that any attempt to use ‘being’ to describe God will inevitably make him merely some object in our ontology alongside other beings, unacceptably (...) mitigating God's radical transcendence and otherness. I will argue that Aquinas has a very creative response to this charge: ‘being’ stands in a unique relationship as the only concept that can ensure we do not draw God under some particular creaturely limit and thus use divine names to create an ‘idol’. In other words, ‘being’ is a special paradigm concept/term which ensures that we preserve humility in our attempts to name God. -/- . (shrink)
