12The Motivational Spectrum of SkillRes Philosophica 103 (1): 19-44. 2026.A recent discussion in virtue ethics revives the question of how virtue relates to skill. Is skill merely a useful analog to explaining the nature of virtue, or is virtue actually a skill? The motivation objection is one of a number of arguments that virtue is not a skill. The idea is that virtues are motivationally constrained by requiring their possessors to have certain concerns, goals, and motivations, but skills are not. In this paper, we argue that the motivation objection fails because, c…Read more

77The Key to Happiness: Thomas Aquinas’s Summa Theologiae, Part I-II, Question 2The Philosophy Teaching Library. 2025.Thomas Aquinas was one of the greatest philosophers and theologians of the medieval period, and his account of happiness is one of the most influential in the Western tradition. For Aquinas, happiness is the final end and highest good that all of us seek in life. But not everyone agrees about what makes human beings happy. This piece is an exposition and commentary on Aquinas’s Summa Theologiae, Part I-II, Question 2, which asks the question: What does happiness consist in? What is the final end…Read more

99A Thomistic Account of Virtue as ExpertiseStudies in Christian Ethics 36 (2): 254-273. 2023.A healthy Thomism is one engaged with the discoveries and challenges of other traditions and disciplines. In this article I argue for one way of integrating Thomistic ethics and recent work in psychology. I assert that Thomists should think of virtue as a kind of expertise, something that psychologists have studied for decades. First, I provide context and motivation for my integration project. Next, I offer a definition of expertise and contrast it with recent discussions of skill and Aristotle…Read more

734Thomas Aquinas on Separated Souls as Incomplete Human PersonsThe Thomist 83 (4): 589-637. 2019.In recent years an old Thomistic debate on the separated soul has been resurrected. All parties to the debate agree that, for Aquinas, the separated soul (anima separata) designates the rational soul of a human person that survives the death of the human and, prior to the resurrection, the rational soul subsists in itself unnaturally apart from the body of which it is the substantial form in statu viae. According to some Thomists, called ‘corruptionists,’ the separated soul is not a person. Cont…Read more

2502Correcting Acedia through Gratitude and WonderReligions 458 (12): 1-15. 2021.In the capital vices tradition, acedia was fought through perseverance and manual labor. In this paper, I argue that we can also fight acedia through practicing wonder and gratitude. I show this through an account of moral formation developed out of the insight of the virtues and vices traditions that character traits affect how we see things. In the first section, I use Robert Roberts’s account of emotions to explain a mechanism by which virtues and vices affect vision and thus moral formation.…Read more

119Virtue and the Psychology of HabitAmerican Catholic Philosophical Quarterly 96 (2): 291-315. 2022.An exciting trend in virtue ethics is its engagement with empirical psychology. Virtue theorists have connected virtue to various constructs in empirical psychology. The strategy of grounding virtue in the psychological theory of habit, however, has yet to be fully explored. Recent decades of psychological research have shown that habits are an indispensable feature of human life, and virtues and habits have a number of similarities. In this paper, we consider whether virtues are psychological h…Read more

1269After Survivalism and Corruptionism: Separated Souls as Incomplete PersonsQuaestiones Disputatae 10 (2): 161-176. 2020.Thomas Aquinas consistently defended the thesis that the separated rational soul that results from a human person’s death is not a person. Nevertheless, what has emerged in recent decades is a sophisticated disputed question between “survivalists” and “corruptionists” concerning the personhood of the separated soul that has left us with intractable disagreements wherein neither side seems able to convince the other. In our contribution to this disputed question, we present a digest of an unconsi…Read more

125The Virtue of SomnienceAmerican Catholic Philosophical Quarterly 94 (4): 611-637. 2020.It’s strange that sleep doesn’t come up more when we think of virtue. In this paper, I argue that there is a virtue concerned with sleep, which I call “somnience,” and I develop an account of this virtue. My account of somnience builds on the virtue tradition of Aristotle and Aquinas and recent research about the nature of sleep. In the first section I argue that there is a need for such a virtue. Next, I argue that somnience is a form of temperance. Third, I show how somnience connects to a num…Read more

1926A Perspectival Account of Acedia in the Writings of KierkegaardReligions 80 (11): 1-23. 2020.Søren Kierkegaard is well-known as an original philosophical thinker, but less known is his reliance upon and development of the Christian tradition of the Seven Deadly Sins, in particular the vice of acedia, or sloth. As acedia has enjoyed renewed interest in the past century or so, commentators have attempted to pin down one or another Kierkegaardian concept (e.g., despair, heavy-mindedness, boredom, etc.) as the embodiment of the vice, but these attempts have yet to achieve any consensus. In …Read more

74Divine authority and the virtue of religion: a Thomistic response to MurphyInternational Journal for Philosophy of Religion 86 (3): 213-226. 2019.In his book, An Essay on Divine Authority, Mark Murphy argues that God does not have practical authority over created, rational agents. Although Murphy mentions the possibility of an argument for divine authority from justice, he does not consider any. In this paper, I develop such an argument from Aquinas’s treatment of the virtue of religion and other parts of justice. The divine excellence is due honor, and, as Aquinas argues, honoring a ruler requires service and obedience. Thus, a classical…Read more

110The Virtual Presence of Acquired Virtues in the ChristianAmerican Catholic Philosophical Quarterly 93 (1): 75-100. 2019.Aquinas’s doctrine that infused virtues accompany sanctifying grace raises many questions. We examine one: how do the infused virtues relate to the acquired virtues? More precisely, can the person with the infused virtues possess the acquired virtues? We argue for an answer consistent with and informed by Aquinas’s writings, although it goes beyond textual evidence, as any answer to this question must. There are two plausible, standard interpretations of Aquinas on this issue: the coexistence vi…Read more

141The Certainty of Faith: A Problem for Christian Fallibilists?Journal of Analytic Theology 3 130-146. 2015.According to epistemic fallibilism, we cannot be certain of anything. According to the Christian tradition, faith comes with certainty. I develop this dilemma from recent accounts of fallibilism and various representatives of the Christian tradition. I then argue that on John Henry Newman's account of faith the dilemma is merely apparent. Finally, I develop Newman's account of the certainty that accompanies faith and is compatible with fallibilism.

119Distinguishing Desire and Parts of HappinessAmerican Catholic Philosophical Quarterly 89 (1): 97-114. 2015.Germain Grisez has recently argued that Aquinas’s claim that God alone is our ultimate end is incompatible with other claims central to Aquinas’s account of happiness. Two of these arguments take their point of departure from Aquinas’s distinction between essential perfections and perfections of well-being. I argue that both of these arguments fail. The first, which argues that the distinction is incompatible with the beatific vision being perfect fulfillment, fails because it neglects a distinc…Read more

1488The Acquired Virtues are Real VirtuesFaith and Philosophy 32 (4): 453-470. 2015.In a recent paper, Eleonore Stump argues that Aquinas thinks the acquired virtues are “not real at all” because they do not contribute to true moral life, which she argues is the life joined to God by the infused virtues and the gifts and fruits of the Holy Spirit. Against this, I argue in two stages that Aquinas thinks the acquired virtues are real virtues. First, I respond to Stump’s four arguments against the reality of the acquired virtues. Second, I show four ways in which the acquired virt…Read more
