Aquinas’ anthropology is commonly believed to prevent the mind–body problem by treating the human being as one substance, and the soul as a formal cause. Thomists’ descriptions of Aquinas’ anthropology tend to understate or even omit its more dualistic elements, e.g., that the soul is an agent cause that moves the body, and that acts through the mediation of the ‘corporeal spirits’. More importantly, these descriptions overlook that Aquinas himself recognizes a problem of mental causality and even argues for some solutions to it. This paper aims to show that there is such a problem within Aquinas’ conceptual frame, and that contemporary Thomist anthropologies are also vulnerable to it.

While many people think of self-knowledge as about having particular knowledge of oneself, and contemporary philosophers think of self-knowledge as about knowing one’s own mental states, historically, many thinkers have thought about self-knowledge as about knowing one’s nature. This is clear in Thomas Aquinas’s account of self-knowledge. Yet how is knowing one’s nature, which is one of the least individual aspects of oneself, self-knowledge rather than more general anthropological knowledge? This article defends the idea that there is a knowledge of one’s nature which qualifies as self-knowledge and not just anthropological knowledge. In particular, it defends Aquinas’s conception of self-knowledge in dialogue with contemporary epistemology and Leo Tolstoy’s ‘The Death of Ivan Ilyich’. It is argued that Aquinas’s account of self-cognition describes a first-personal knowledge of our nature which is self-knowledge insofar as it is acquired through reflection on one’s experience of oneself in contrast to third-personal anthropological knowledge.

This contribution proposes an interpretation of Thomas Aquinas’s philosophy of mathematics. It is argued that Aquinas’s philosophy of mathematics is a coherent view whose main features enable us to understand it as a moderate realism according to which mathematical objects have an esse intentionale. This esse intentionale involves both mathematicians’ intellectual activity and natural things being knowable mathematically. It is shown that, in Aquinas’s view, mathematics’ constructive part does not conflict with mathematical realism. It is also held that mathematics’ imaginative reasoning is coherent with Aquinas’s doctrine of formal abstraction and his realistism. It focuses on some of Aquinas’s texts, which it places within their textual and doctrinal context and interprets them in the light of some historical elements.

Much has been written of John Courtney Murray’s reception of Thomas Aquinas. Although not totally misplaced, this near-exclusive attention to Aquinas’s role in Murray’s thought has obscured the contributions of an equally important figure—Augustine of Hippo—to Murray’s political theology. This article thus offers a novel survey of Murray’s seminal We Hold These Truths and reveals that Augustine’s theory of Divine Providence, as articulated in The City of God, circumscribed Murray’s Thomism. With the hope of reconciling differences between American Catholics and non-Catholics at mid-century, Murray relied upon two of the most influential theologians in western Christianity to assert that Divine Providence led the Founding Fathers to place the natural law and religious liberty at the foundation of the American republic.

According to Joel Feinberg and most modern scholars of desert, the basis of desert must be a fact about the deserving person, and not about someone else. This widely accepted notion seems self-evident. However according to some religious traditions, such as Buddhism and Roman Catholicism, merit can be transferred from one person to another. That is, someone can deserve something based on some fact about someone else, such as the fact that someone else has carried out an action. This article examines the Catholic concept of merit transfer, first distinguishing it from other contemporary qualifications to the claim that a desert basis must be something about the deserving person. Then the article draws on Thomas Aquinas's explanation of the central role of relationship and love in merit and how it justifies merit transfer to address several objections made by modern scholars to such transfers. After addressing these objections, the article argues that literal understandings of merit transfer are preferable to metaphorical ones, and lastly some implications of merit transfer for Christian theology and the theory of desert more broadly are briefly discussed.

This paper introduces Phenomenological Thomism by accomplishing the three tasks Thomas Aquinas sets for every prooemium. First, to promote goodwill (beniuolus), it shows how fruitful Phenomenological Thomism promises to be by arguing that it unites the strengths of two complementary alternatives to the modern starting point. Second, to make teachable (docilis), it delineates the principal vectors of phenomenological engagement, including philosophy of nature, philosophical anthropology, ethics, epistemology, metaphysics, philosophical theology, and revealed theology. Third, to arouse attention (attentus), it focuses on the theme of manifestation to highlight the challenge of bringing the two traditions together. In this way, the prooemium encourages the further development of Phenomenological Thomism as a research program involving countless scholars and an infinity of tasks.

The majority of studies on ‘faith’ (fides) in the thought of Thomas Aquinas consider it in a religious or theological context: fides as the theological virtue by which one assents to the truths of divine revelation. The focus on theological faith is appropriate, given its central importance as a theological virtue, but this is not the only sense of fides that Thomas identifies. The present study investigates two non-theological senses formulated in his commentary on the De Trinitate of Boethius: first, fides as the proximate cause of assenting to principles within a given science (‘epistemic faith’) and, second, fides as an indispensable element of society (‘societal faith’). These senses have been largely overlooked in secondary literature but, I argue, might help to dispel mischaracterizations of faith as fundamentally unreasonable.

The basic question of this article is whether Thomas Aquinas's doctrine of divine providence through his understanding of primary and secondary causation can be understood as a theological causal or non-causal explanation. To answer this question, I will consider some contemporary discussions about the nature of causal and non-causal explanations in philosophy of science and metaphysics, in order to integrate them into a theological discourse that appeals to the classical distinction between God as first cause and creatures as secondary causes to explain God's presence and providence in the created universe. My main argument will hold that, even if there are some philosophical models of explanation that seem to allow one to suggest that, at least partially, this doctrine could be seen as a non-causal theological explanation, there are other models that offer seemingly stronger reasons to see this doctrine in full as a causal theological explanation.

The development of Thomas’s teaching on Christ’s headship relies upon the principle of the causality of the maximum: ‘the maximum in a genus is the universal cause in that genus’. This principle appears in the fourth way to demonstrate God’s existence. Applied to the humanity of Christ, Thomas argues that Christ, on account of his perfect fullness of grace, is, according to his humanity, the universal source of grace for all the members of the Church, including the angels. How does this cohere with Thomas’s teaching elsewhere in the Summa theologiae that it is only as Word that Christ causes grace in the angels? In this paper, I explore this tension and offer a way of understanding Thomas’s broader approach to the mystery of Christ.

This paper examines, from a Thomistic perspective, the possible consequences of the twentieth-century reform of the ‘Kyrie eleison’ from ninefold set of invocations to a sixfold call-and-response structure. First, we present Aquinas’s distinctly Trinitarian exegesis of the ‘Kyrie’ in light of the history of troped liturgical texts. Next, we will account for the historical diversity of the troped ‘Kyrie’ genre while emphasizing importance of the Trinitarian elements. The third section recounts recent work on Aquinas’s theory of the passions and their effects of language formation; this leads to the fourth section, which casts a philosophical eye on the role of melisma in the liturgy. To conclude this study, we suggest the restoration of some troped ‘Kyrie’ texts in the Roman Rite.

From 1923 to the present day, various studies have increasingly analysed the beginnings of the cult of Thomas Aquinas, as well as the authenticity of his works. Over the last century, the reception of Thomas Aquinas between these two poles of sanctity and the authority accorded to his works has shown itself to be a significant pairing, of which this article unpacks some important stages.
