    Unrepresented patients cannot make their own medical decisions and do not have any surrogate decision-maker. This patient population is highly vulnerable to being harmed, wronged, ignored, and exploited. But the ethical issues related to their care have gotten little attention from Christian bioethicists, which is problematic in light of Christianity’s concern for the poor, the needy, and the vulnerable. This article claims that Christian bioethicists must address these issues, and that Christia…Read more

    The Value of Life: A Natural Law Account
    The Journal of Ethics. forthcoming.
    The value of human life has a central importance in bioethics and in the Thomistic natural law tradition, but its meaning is often ambiguous. It can refer to the value of human _life itself_, the value of a person’s _life_, or the value of _the person_ whose life it is. These are different kinds of value, but they are often overlooked or conflated in the literature. This article aims to clarify and develop natural law ethics by analyzing two goods associated with the value of life: well-being an…Read more

    Reflecting on Principlism: Explaining, But Not Guiding, Clinical Ethics Analysis
    American Journal of Bioethics 26 (3): 19-25. 2026.
    Tom Beauchamp’s contributions to the field of bioethics are as influential as they are numerous. Here we reflect on his intellectual legacy, specifically his role in establishing principlism as a method of bioethical analysis. Despite its prominence in medical ethics education, in our experience as clinical ethicists and researchers, we rarely analyze ethical issues the way principlism suggests, either in the clinic or our scholarship. In this paper, we consider the complex ways in which princip…Read more

    In a forthcoming book titled The Emerging Tradition of Bioethics, we take up Parker’s timely question, ‘How should the role(s) of bioethics be understood in the context of a world of intense value conflict and polarisation?’. Specifically, we focus on whether the field of bioethics in the pluralistic and increasingly polarised American context can give justified moral guidance in foundational, clinical, research and public health domains.

    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

    God and Happiness
    Cambridge University Press. 2024.
    This book explores the connection between God and happiness, with happiness understood as a life of well-being or flourishing that goes well for the one living it. It provides a historical and contemporary survey of philosophical questions, theories, and debates about happiness, and it asks how they should be answered and evaluated from a theistic perspective. The central topics it covers are the nature of happiness (what is it?), the content of happiness (what are the constituents of a happy li…Read more

    The Ethics of Clinical Ethics
    HEC Forum 37 (3): 389-410. 2025.
    The concept ethics defines health care ethics as a professional practice. Yet the meaning of “ethics” is often unclear in the theory and practice of clinical ethics. Clarity on this matter is crucial for understanding the nature of clinical ethics and for debates about the professional identity and proper role of ethicists, the sort of training and skills they should possess, and whether they have ethics expertise. This article examines two different ways the ethics of clinical ethics can be und…Read more

    The Ethical Standard for End-of-Life Decisions for Unrepresented Patients
    American Journal of Bioethics 25 (9): 74-85. 2025.
    There has been increasing awareness of the medical and moral challenges in the care of unrepresented patients: those who cannot make their own medical decisions, do not have any surrogate decision maker, and have not indicated their treatment preferences. Most discussions have focused on procedural questions such as who should make decisions for these patients. An issue that has not gotten enough attention is the ethical standard that should govern medical decision making. I explore the question…Read more

    Value Incommensurability in Natural Law Ethics: A Clarification and Critique
    American Catholic Philosophical Quarterly 97 (3): 361-386. 2023.
    The foundation of natural law ethics is a set of basic human goods, such as life and health, knowledge, work and play, appreciation of beauty, friendship, and religion. A disputed question among natural law theorists is whether the basic goods are “incommensurable.” But there is widespread ambiguity in the natural law literature about what incommensurability means, which makes it unclear how this disagreement should be understood and resolved. First, I clear up this ambiguity by distinguishing b…Read more

    The Natural Law Ethics of Star Wars
    with Joel Archer and Daniel Banning
    In Jason T. Eberl & Kevin S. Decker (eds.), Star Wars and Philosophy Strikes Back, Wiley-blackwell. 2023.
    According to George Lucas, Star Wars is a morality play, a mythological tale of good and evil that's meant to teach timeless lessons about the moral life. This chapter shows how the moral framework of natural law ethics provides a philosophical foundation for the morality of the Force and helps illuminate Star Wars' moral themes.

    Value Comparability in Natural Law Ethics: A Defense
    Journal of Value Inquiry 58 (3): 383-402. 2024.
    The foundation of natural law ethics is a set of basic human goods, such as life and health, knowledge, work and play, the appreciation of beauty, friendship, and religion. A disputed question among natural law theorists is whether the basic goods can be measured or compared in terms of their value. Proponents of New Natural Law Theory, the best-known version in the contemporary literature, hold that basic goods are both incommensurable and incomparable. Proponents of Classical Natural Law Theor…Read more

    Perfectionism is the view that what is intrinsically good is the fulfillment of human nature or the development and exercise of the characteristic human capacities. An important objection to the theory is what Gwen Bradford calls the “Deep Problem”: explaining why nature-fulfillment is good. We argue that situating perfectionism within a Thomistic metaethical framework and adopting Aquinas's account of the metaphysical “convertibility” of being and goodness gives us a solution to the Deep Proble…Read more

    When decisionally incapable patients need a surrogate to make medical decisions for them, sometimes the patient has not appointed a healthcare agent and there is intractable disagreement among potential surrogates of equal priority, legal rank, or relation to the patient (e.g., child vs. child, sibling vs. sibling). There is no ethical, legal, or professional consensus about how to identify the appropriate surrogate in such circumstances. This article presents a case study involving an elderly f…Read more

    Principlism’s Balancing Act: Why the Principles of Biomedical Ethics Need a Theory of the Good
    Journal of Medicine and Philosophy 45 (4-5): 441-470. 2020.
    Principlism, the bioethical theory championed by Tom Beauchamp and James Childress, is centered on the four moral principles of beneficence, non-maleficence, respect for autonomy, and justice. Two key processes related to these principles are specification—adding specific content to general principles—and balancing—determining the relative weight of conflicting principles. I argue that both of these processes necessarily involve an appeal to human goods and evils, and therefore require a theory …Read more

    The Quality of Life is Not Strained: Disability, Human Nature, Well-Being, and Relationships
    Kennedy Institute of Ethics Journal 29 (4): 333-366. 2019.
    This paper explores the relationship between disability and quality of life and some of its implications for bioethics and healthcare. It focuses on the neglected perfectionist approach that ties well-being to the flourishing of human nature, which provides the strongest support for the common view of disability as a harm. After critiquing the traditional Aristotelian version of perfectionism, which excludes the disabled from flourishing by prioritizing rationalistic goods, I defend a new versio…Read more

    God, evil, and occasionalism
    Religious Studies 54 (2): 265-283. 2018.
    In a recent paper, Alvin Plantinga defends occasionalism against an important moral objection: if God is the sole direct cause of all the suffering that results from immoral human choices, this causal role is difficult to reconcile with God’s perfect goodness. Plantinga argues that this problem is no worse for occasionalism than for any of the competing views of divine causality; in particular, there is no morally relevant difference between God directly causing suffering and God indirectly caus…Read more

    Aquinas on God-Sanctioned Stealing
    American Catholic Philosophical Quarterly 92 (2): 277-293. 2018.
    A serious challenge to religious believers in the Abrahamic traditions is that the God of the Old Testament seems to command immoral actions. Thomas Aquinas addresses this objection using the biblical story of God ordering the Israelites to plunder the Egyptians, which threatens to create an inconsistency among four of Aquinas’s views: God did indeed command this action; God is perfectly good and cannot command any evil actions; the objective moral goodness or badness of actions is not based on …Read more

    I propose and defend a new combination of natural law ethics and virtue epistemology. While all contemporary natural law theories recognize knowledge as one of the basic human goods, none of them provide a detailed explanation for the value of knowledge, which would greatly enrich such theories. I show that virtue epistemology is able to deliver the required solution to the value problem, which makes this combination project very attractive. I also address two major worries about this approach: …Read more

    Human Nature and Moral Status in Bioethics
    Journal of Medicine and Philosophy 43 (2): 115-131. 2018.
    The articles in this issue cover a wide range of topics, including the moral status of human embryos and human-animal chimeras and hybrids, the determination of death, theories of human cognition, and policies on the identity of mitochondrial donors. Despite this variety, there are two underlying questions that tie the articles together: what is a human being? And, what is the basis of moral status? First, I discuss these two questions and why they are important for bioethics. Then I provide sum…Read more

    Thomistic Eudaimonism, Virtue, and Well-Being
    Southwest Philosophy Review 33 (1): 173-185. 2017.
    In contemporary discussions of human well-being, well-being is typically understood in secular terms. Analogously, most contemporary discussions of eudaimonistic virtue ethics, influenced by Aristotle, take human flourishing to be a matter of living virtuously, where flourishing and virtue are both secular notions. For many religious believers, however, well-being and virtuous activity involve not just ethical dispositions and actions, but primarily relationship to God. In this paper, I present …Read more
