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.

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._.

Building on the system of reason provided for by the Greek philosopher and specifically Aristotle, St. Thomas Aquinas built a comprehensive system and theory of natural law which has lasted through the ages. The theory was further developed in the Middle Ages and in the Enlightenment Ages by many a prominent philosopher and economist and has been recognized in the Modern Age. The natural law-theory and system has been repeatedly applied to the spheres of economic thought and has (...) produced many lasting contributions such as private property rights and individual rights. In recent times with the collapses of the financial system and rapid globalization, there has been a renewed interest in the application of natural law theory to economics to counter a certain anthropology and distortion of values created by a modern economic system of selfpreservation deriving its insights from the philosophies of Thomas Hobbes and Niccolo Machiavelli.

There are two general routes that Augustine suggests in De Trinitate, XV, 14-16, 23-25, for a psychological account of the Father's intellectual generation of the Word. Thomas Aquinas and Henry of Ghent, in their own ways, follow the first route; John Duns Scotus follows the second. Aquinas, Henry, and Scotus's psychological accounts entail different theological opinions. For example, Aquinas (but neither Henry nor Scotus) thinks that the Father needs the Word to know the divine essence. If (...) we compare the theological views entailed by their psychologies we find a trajectory from Aquinas, through Henry, and ending with Scotus. This theological trajectory falsifies a judgment that every Augustinian psychology of the divine persons amounts to a pre-Nicene functional Trinitarianism. This study makes clear how one's awareness of the theological views entailed by these psychologies enables one to assess more thoroughly psychological accounts of the identity and distinction of the divine persons.

This is an excerpt of Aquinas' proof of the existence of God. In proving God's existence, Aquinas lays out a cosmological argument of which also sets that tone for his seminal work in epistemology.

Can the persistence of a human being's soul at death and prior to the bodily resurrection be sufficient to guarantee that the resurrected human being is numerically identical to the human being who died? According to Thomas Aquinas, it can. Yet, given that Aquinas holds that the human being is identical to the composite of soul and body and ceases to exist at death, it's difficult to see how he can maintain this view. In this paper, I (...) address Aquinas's response to this objection . After making a crucial clarification concerning the nature of the non-repeatability principle on which the objection relies, I argue that the contemporary notion of immanent causal relations provides us with a way of understanding Aquinas's defence that renders it both highly interesting and philosophically plausible.

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.

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. -/- .

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)

Recently, the Intelligent Design (ID) movement has challenged the claim of many in the scientific establishment that nature gives no empirical signs of having been deliberately designed. In particular, ID arguments in biology dispute the notion that neo-Darwinian evolution is the only viable scientific explanation of the origin of biological novelty, arguing that there are telltale signs of the activity of intelligence which can be recognized and studied empirically. In recent years, a number of Catholic philosophers, theologians, and scientists have (...) expressed opposition to ID. Some of these critics claim that there is a conflict between the philosophy of St. Thomas Aquinas and that of the ID movement, and even an affinity between Aquinas’s ideas and theistic Darwinism. We consider six such criticisms and find each wanting. (shrink)

An overview of debates in ethical theory within Christian Scholasticism in the decades after Thomas Aquinas.

The article begins with an inquiry on St. Thomas Aquinas' theological framework of God in the Summa Theologica, as seen through the lenses of Pseudo Dionysius and Proclus Lycaeus, in the Light of Plato's dialectical exploration of the One in the Parmenides. We proceed to the similarities and differences between St. Thomas Aquinas’ theology and Plato’s philosophy in terms of the means through which the soul ascends towards the highest vision. Ideas of thinkers such as Democritus, (...) Aristotle, Iamblichus, Thomas Taylor, Friedrich Nietzsche and Martin Heidegger supported or provided counter arguments regarding these matters. The essay raises a significant question pertaining to the relationship between Plato’s thought with that of St. Thomas Aquinas’. (shrink)

Servais Pinckaers, in his most important work, The Sources of Christian Ethics, asks the provocative question: is the Moral Theology of St. Thomas Aquinas Christian or, alternatively, does Aquinas rely so much on the ethics of Aristotle that his teaching is merely philosophical? This paper presents an overview of Pinckaers’s answer to this question. His answer is important in that it addresses a common misinterpretation of St. Thomas, which is to overstress his Aristotelian influence and understate (...) his reliance on Scripture, the Fathers (especially Augustine), and the New Law of the Gospel. In this way Pinckaers forms part of a ressourcement in Thomistic studies that seeks to reaffirm the evangelical character of Aquinas’s work and its importance in the renewal of Moral Theology called for at Second Vatican Council.

This article seeks to justify the claim that Thomas Aquinas proposed a concept of natural law which is immune to the argument against the recognition of an objective grounding of the good formulated by a well-known representative of the liberal tradition, Isaiah Berlin, in his famous essay “Two Concepts of Freedom.” I argue that Aquinas’s concept of freedom takes into account the very same values and goals that Berlin set out to defend when he composed his critique (...) of natural law. In particular, the article suggests that Aquinas recognizes freedom as a greater perfection of man than rationality, and that this freedom is realized, among other things, through the co-construction of the good that gives a goal and a shape to human action and to the whole of a person’s life. I argue that the co-construction of such a good involves the co-construction of natural law in the strict sense of the term. Indeed, the content of natural law can be understood as a set of goods which are goals that inform human action. From a human perspective, natural law is not a pre-existing recipe which has merely to be “read.” Defining the concrete content of natural law is an ongoing process. The process of defining natural law’s content takes humanly knowable, objective elements into account, and so draws on knowledge. Yet free choice also plays an important part in this process. When speaking of the process of defining the content of natural law, therefore, and in determining what here-and-now is to be done, it is reasonable to describe man as a creator of the natural law, or as a legislator, just as the members of a parliament are the creators of civil law — bearing in mind that only a just law is truly law and therefore the creation of both civil and natural law reaches only as far is the scope of just actions directed by these laws. From the perspective of human action, we may speak of each person’s free choice to establish a given good as the end of a specific act, and in so doing to declare that action proper under natural law in the strict sense of the term (which differs from the rules of natural law). An appreciation of what is particular and individual (particulare et individuum), and an appreciation of free choice that goes hand-in-hand with this, is deeply embedded in Thomas’s system of thought. Particularity and individuality has its basis in an especially excellent way of human existence. (shrink)

From the perspective of Aquinas’ Biblical commentaries, the article develops the reflection on pignus / arra haereditatis (Eph 1:5) seeing these essential elements of Thomas’ reflection on salvation in the terminological question of which one is better: pignus or arra, namely the pledge or the earnest/deposit. Thomas develops soteriology, which indicates that human salvation starts “now” and not “later,” through the participation in the Passion of Christ and in His merits. Analyzing Aquinas’ commentary on Ps 21, (...) on the Letter to the Ephesians and on the Letter to the Galatians together with the themes of Christ’s obedience and its soteriological significance as well as His wish of voluntary death for us, the article shows the Biblical roots of Thomas’ soteriology. The author devotes particular attention to the analysis of the logic of inchoatio and consummatio in Thomas’ soteriological grammar and his understanding of faith as the beginning of eternal life and the ensuing consequences.

Bernard McGinn was a great historian of Christianity. But in this book under review he fails to do justice to the history of the Summa. He fails to understand the ontologies of the economic theories of Bernard Lonergan and the theology of Karl Rahner, for examples. The book is patchy and seems under-researched. McGinn does not do justice to the influence of the Summa as a text which forms a bridge between St. Augustine of Hippo and Hannah Arendt and Jean (...) Lyotard.

Za „ojca” filozoficznej kategorii „godności”, która legła u podstaw kategorii prawnej, uznawany jest powszechnie Immanuel Kant. Przypomnieć jednak trzeba, że w bardzo podobny sposób, choć w zasadniczo odmiennym kontekście systemowym, charakteryzował godność Tomasz z Akwinu, pół tysiąca lat wcześniej, uznając ją za fundament bycia osobą. Stąd najistotniejszym i centralnym elementem, tytułowej, klasycznej koncepcji człowieka jest koncepcja godności. Akwinata jest autorem bodaj najbardziej rozbudowanej koncepcji osoby w tradycji filozofii klasycznej. Co więcej zmierzać będę do wykazania, że jego koncepcja lepiej nadaje się (...) do teoretycznego ugruntowania praw człowieka niż koncepcja Kanta. Rekonstruując propozycję Kanta ograniczam się, zasadniczo rzecz biorąc, do analizy Uzasadnienia metafizyki moralności. Interesować będą mnie zagadnienia podstawowe, przede wszystkim – wynikające z różnicy kontekstów systemowych – różnice w pojmowaniu bycia celem samym w sobie. W perspektywie ontologicznej koncentrować się będę na powiązaniu godności z indywidualnością; w perspektywie antropologicznej – na tym, jakiego typu działania stanowią o doskonałości człowieka, jakie działania (czym określone) realizują człowieka jako cel sam w sobie. W szczególności interesować się będę miejscem rozumu i woli w określaniu treści działań (w perspektywie kantowskiej będzie to pytanie o określenie treści powinności; w perspektywie Tomasza – pytanie o treść realizowanego dobra). Zasadnicze pytanie, które leży u podłoża podjętej problematyki antropologicznej, jest pytaniem o to, na ile dla pojmowania godności istotne jest uznanie woli jako w sposób wolny współokreślającej treść powinności (Kant) lub dobra (Akwinata), a na ile woli jedynie podążającej za poznaną powinnością lub poznanym dobrem. Zmierzać będę do uzasadnienia tezy, że koncepcja Akwinaty w ugruntowaniu godności akcentuje wprost indywidualność opartą na wyborze czegoś, co nie jest jednoznacznie treściowo obiektywnie zdeterminowane i co wykracza poza to, co powszechne, poza to, co gatunkowe; natomiast koncepcja Kanta godność wiąże przede wszystkim z tym, co powszechne, gatunkowe i zapoznaje doniosłość indywidualności dla pojmowania godności.

The author attempts to justify the thesis of the servient character of political power. By his analyses, he arrives at two conclusions. First, the ultimate goal of service fulfilled by political power should be identical with the natural goal of every human being, meaning a life of virtue. Hence, service to the cause of the citizens’ virtue requires that the fundamental duties of power include the protection of public peace, the promotion of actions towards the common good, and striving for (...) a common abundance of worldly possessions. Second, to elect those in political power it is necessary to make sure that aspirants to such are characterized by the appropriate level of virtuous development. Each candidate should be first and foremost a person possessing a high moral quality, where prudence and magnanimity appear to be virtues especially fitting power. (shrink)

he present study aims to offer an analysis of the analogical discourse on God from STh. I, q.13 a.3-4. Thomas Aquinas's claim consists, mainly, of presenting a solution to the problem of the foundations that support the theological discourse on God.

It is just this specific framework of previous questions the place of the debate on the analogy, which is considered, (...) in addition, as a type of indirect language that points beyond itself.

In recent scholarship, moral theologians and readers of Thomas Aquinas have shown increasing sensitivity to the role of the passions in the moral life. Yet these accounts have paid inadequate attention to Thomas's writings on Christ's passions as a source of moral reflection. As I argue in this essay, Thomas's writings on Christ's human affectivity should not be limited to the concerns of Christology; rather, they should be integrated into a fuller account of the human passions. (...) One upshot of this approach for Thomists is that it sharpens our vocabulary when describing human nature and the conditions for the moral life. By considering the rubrics of creation, fall, and redemption – as Thomas does – we find that our resources for analyzing the passions are greatly enriched. (shrink)

Some attention has also been devoted to a particular kind of judgment or a particular form of the intellect’s second operation, sometimes named separatio by Thomas. Important editions of questions 5 and 6 of Thomas’s commentary on the De Trinitate of Boethius in 1948 and 1955 and the groundbreaking study by L. B. Geiger in 1947, all have set the stage for further emphasis on this distinctive type of intellectual operation when it comes to one’s discovery of being, (...) or better, of that notion of being that can serve as subject of a science of being as being rather than a science of being as material or as quantified. While this new development has remained largely unnoticed in certain regions of Thomistic scholarship for a number of years, it has been pursued in depth by other writers. At the same time, investigation of the same nicely dovetails with the renewed emphasis on existence and on judgment as the process required to discover being as existing to which we have referred above. For as will be seen below, at least one passage in Thomas’s commentary reinforces the contention that one must pass beyond simple apprehension to the mind’s second operation or to judgment if one is to grasp being explicitly as existing. This particular point, however, is not our primary concern here. (shrink)

A chapter in an encyclopedia for important events for religious history. I discuss the life, works, and influence of Aquinas.

The recent trend among many philosophers of religion has been to interpret divine eternity as an everlasting temporality in which an omnitemporal God exists in and throughout the whole of time. This is in contrast to the classical account of divine eternity as atemporal, immutable existence. In this paper, Aquinas' use of Boethius's definition of eternity as “the whole, perfect, and simultaneous possession of endless life” is analyzed and explained in contradistinction to Aristotle's definition of time. This analysis is (...) then used to respond to Nicholas Wolterstroff's argument in "God Everlasting" that God's knowledge of temporal events infects God with temporality and mutability. The argument concludes by introducing an important distinction between absolute simultaneity and temporal simultaneity, which allows us to hold God is omniscient because he is absolutely simultaneous with all events but is not temporally simultaneous with any event.

Review of the English translation of Bernard Montagnes' influential 1963 monograph on analogy in Aquinas. (Pre-publication copy -- please cite final version.).

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.

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)

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.

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.

Thomas Aquinas wrote a text later known as Quaestio de attributis and ordered it inserted in a precise location of his Commentary on the Sentences of Peter Lombard more than a decade after composing this work. Aquinas assigned exceptional importance to this text, in which he confronts the debate on the issue of the divine attributes that swept the most important centres of learning in 13th Century Europe and examines the answers given to the problem by the (...) representatives of the four mainstream schools of his time: the Greek mystic Dionysius Areopagita, the Latin Saint Anselm of Canterbury, the Jewish rabbi Moses Maimonides and the Muslim philosopher Ibn Sina. This in-depth study of Thomas Aquinas’ Quaestio de attributis (In I Sent., d. 2, q. 1, a. 3) binds together the findings of previous research on the unique history of this text by reconstructing the historical circumstances surrounding its composition, shows that the Quaestio contains Aquinas’ final answer to the dispute on the divine attributes, and thoroughly examines his interpretation of Maimonides’ position on the issue of the knowledge of God by analysing this and other texts related to it chronologically and doctrinally. The examination of the Quaestio reveals the background of Thomas Aquinas’ renewed interest in Maimonides’ position on the issue and brings to light elements of Aquinas’ interpretation that are absent from his earlier references to Maimonides. Moreover, the chronological and doctrinal connection of the Quaestio de attributis to other Thomistic works with explicit references to Maimonides enables a reconstruction of his comprehensive approach to Maimonides’ teaching on the possibility and extent of the knowledge of God in the Guide of the Perplexed and highlights the place of Maimonides’ philosophical teachings in Thomas’ own thought in issues like "Being" as the proper name of God, the multiplicity of the divine names, the beatific vision in the afterlife, the causes that prevent the instruction of the multitude in divine matters and the role of faith and prophecy in the acquisition of the true knowledge of God in this life. The last chapter examines the reasons behind Aquinas’ silencing of Maimonides’ name when introducing his Five Ways for the knowledge of the existence of God, in spite of the evident relation between these and Maimonides’ Four Speculations. The study is completed with an extensive appendix that includes the text of the Quaestio de attributis with an English translation and the critical edition of several chapters of the 13th Century Latin translation of the Guide of the Perplexed known as Dux neutrorum.

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.

This paper will argue that the order and the unity of St. Thomas Aquinas’s five ways can be elucidated through a consideration of St. Thomas’s appropriation of an Avicennian insight that he used to order and unify the wisdom of the Aristotelian and Abrahamic philosophical traditions towards the existence of God. I will begin with a central aporia from Aristotle’s Metaphysics. Aristotle says that the science of first philosophy has three different theoretical vectors: ontology, aitiology, and theology. (...) But how can all three be united into a single Aristotelian science? In his Metaphysics of the Healing, Avicenna resolved the impasse by taking the ontological vector as the subject of metaphysics. He then integrated the question of the four first causes into the penultimate stage of his demonstration for the existence of God, thereby placing aitiological and theological questions among the ultimate concerns of a unified Aristotelian metaphysics. In the five ways, St. Thomas integrated Avicenna’s Aristotelian search for the first four causes into the last four of his five ways, by showing that each of the four aitiological orders terminate in an ultimate first cause that we call God. Finally, by appending the proof from the Physics to the beginning of the five ways, St. Thomas was able to show that the ultimate aim of both natural philosophy and metaphysics is the divine first principle, which is the beginning and subject of sacra doctrina.

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)

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.

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)

This paper explores Thomas Aquinas’ and Richard Swinburne’s doctrines of simplicity in the context of their philosophical theologies. Both say that God is simple. However, Swinburne takes simplicity as a property of the theistic hypothesis, while for Aquinas simplicity is a property of God himself. For Swinburne, simpler theories are ceteris paribus more likely to be true; for Aquinas, simplicity and truth are properties of God which, in a certain way, coincide – because God is metaphysically (...) simple. Notwithstanding their different approaches, some unreckoned parallels between their thoughts are brought to light. (shrink)

Arguments concerning the nature of natural evil vary in their conclusions depending on the particular approach with which they commence inquiry; one of the most contested conclusions regards evil as privation, sourcing its justification primarily from Aquinas’ metaphysical conception of good as being and evil as non-being. It should be of no surprise, then, that the dismissal of natural evil’s privative nature comes about when the understanding of natural evil favours a phenomenological approach rather than a metaphysical one. Proponents (...) of said dismissal generally centre their claims around the notion of pain and suffering as substantially contentful – as in, non-privative – experiences of evil. On the other hand, theorists espousing the privation account generally argue that characterisations of pain and suffering as necessarily evil do not consider the context of orientation towards individual wellbeing within which pain/suffering experiences naturally function. Furthermore, some of the arguments for the privation account’s dismissal seem to disregard completely the Thomistic sense of the form and hierarchy of the good, which ends up straw-manning the privation account to a point where it can no longer reconcile the awfulness of experienced pain and suffering with these experiences not being necessarily evil. The importance of understanding this Thomistic sense is further emphasised in its capacity to explain why a divine and fully good Creator would involve the world with such evil. Thus, this paper first considers the account of evil given in question one of Aquinas’ De malo, along with contemporary arguments for the nature and purpose of evil as privation; second, these are then used as resources to help make sense of, one, the general nature of pain and suffering, and two, some of their specific expressions as found in disease and depression, and throughout evolutionary history.

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)

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.
