The beatific vision is central to St. Thomas Aquinas’ doctrine of the soul’s enlightenment. In its vision of the essence of God, the soul/intellect achieves its telos, its highest goal. But the resurrection of the body is a central dogma of the Christian faith, so the main question of this essay concerns the manner in which the resurrected body of the blessed benefits from the soul’s apprehension of the beatific vision. For St. Thomas, the physical eyes do not see the (...) beatific vision, since they can only see magnitude and proportion, and God is beyond both. The soul is the body’s substantial form, and a person is not fully a person without the union of soul and body. As the body’s substantial form, the soul/intellect has the beatific vision as its substantial form. The result of the enlightened intellect with the resurrected body will be that the physical eyes will be able to see more readily the glory of God in creation and in redeemed humanity, and more supremely in the incarnate Christ himself.

In Summa Theologiae I.76.1 Aquinas presents an argument for the hylomorphic union of body and soul that he attributes to Aristotle. Aquinas builds on Aristotle’s original argument, however, offering his own short but powerful line of reasoning in support of one of the main premises. This additional argument involves an appeal to the principle that nothing acts except insofar as it is in act. This principle has roots in the thought of Aristotle, but is not explicitly used by him. It (...) is, however, fundamental for Aquinas and pervasive throughout his work. In this paper I examine the principle and its implications for Aquinas’ version of the argument. Furthermore, I argue that the principle is foundational to Aquinas’ criticisms of Averroes’ account of the intellective soul and that its inclusion renders Aquinas’ version of the argument incompatible with Averroes’ view.

In addressing bioethical issues at the beginning of human life, such as abortion, in vitro fertilization, and embryonic stem cell research, one primary concern regards establishing when a developing human embryo or fetus can be considered a person. Thomas Aquinas argues that an embryo or fetus is not a human person until its body is informed by a rational soul. Aquinas's explicit account of human embryogenesis has been generally rejected by contemporary scholars due to its dependence upon medieval biological data, (...) which has been far surpassed by current scientific research. A number of scholars, however, have attempted to combine Aquinas's basic metaphysical account of human nature with current embryological data to develop a contemporary Thomistic account of a human person's beginning. In this article, I discuss two recent interpretations in which it is argued that a human person does not begin to exist until a fetus has developed a functioning cerebral cortex. (shrink)

Thomas Aquinas persistently defended the idea that the soul survives physical death. But what exactly is the rational soul that becomes separated from the body at death? When a person’s body dies, do they cease to exist? Over the past few decades, a nuanced debate has developed between “survivalists” and “corruptionists” over whether or not a separated soul is still a person, leading to impenetrable disagreements in which neither side can seem to sway the other. In this research, I propose (...) a previously unexplored answer to this contentious query: that a person whose soul has been separated from their body is an incomplete human being. (shrink)

A surgical head-transplant technique, HEAVEN, promises to offer significantly improved quality of life for quadriplegics and others whose minds are functional, but whose bodies require artificial support to continue living. HEAVEN putatively actualizes a thought-experiment long debated by philosophers concerning the definition of personhood and criterion of personal identity through time and change. HEAVEN’s advocates presume to preserve the identity of the person whose head is transplanted onto another’s living body, leaving one’s previous body behind as one would their corpse. (...) Various classical and contemporary theories of personhood and personal identity would support this presumption, while others would contest it as providing an accurate or complete view of what is essential for a human person to persist through this procedure. This paper brings such theories to bear in analyzing whether HEAVEN can indeed deliver on its promise of complete ontological survival for the person whose head is transplanted. (shrink)

Some bioethicists have argued that moral bioenhancement, complementing traditional means of enhancing individuals’ moral dispositions, is essential if we are to survive as a species. Traditional means of moral enhancement have historically included civil legislation, socially recognized moral exemplars, religious teachings and disciplines, and familial upbringing. I explore the necessity and feasibility of pursuing methods of moral bioenhancement as a complement to such traditional means, grounding my analysis within a virtue-theoretic framework. Specifically, I focus on the essential intellectual virtue for (...) proper moral reasoning, prudence, and whether proposed methods of moral bioenhancement could facilitate the cultivation of this virtue within the psyches of moral agents. I conclude that certain means of bioenhancement may serve to augment the ability to reason prudentially and assist moral agents to align their wills with their higher-order rational desires, though such means require those higher-order desires to already have been formulated independently.

Many debates in arenas such as bioethics turn on questions regarding the moral status of human beings at various stages of biological development or decline. It is often argued that a human being possesses a fundamental and inviolable moral status insofar as she is a “person”; yet, it is contested whether all or only human beings count as persons. Perhaps there are non-human person, and perhaps not every human being satisfies the definitional criteria for being a person. A further question, (...) which will be the primary focus of this paper, concerns what essential features of personhood endow persons, human or otherwise, with their moral status and the inherent rights they concomitantly possess. A survey of the history of philosophical theorizing on what it means to be a person yields a broad consensus upon the key capacities being rational thought, self-consciousness, and autonomous volition. It is not sufficient, however, simply to cite these capacities, but to explain why these particular capacities bear moral import. A more recent concern has developed regarding the possible future existence of so-called “post-persons” who, due to their enhanced cognitive and emotive capacities, may be morally superior to mere persons and thereby possess a higher moral status. This paper will conclude with an analysis of the extent to which this concern is warranted. (shrink)

In this paper, I confront Engelhardt’s views—conceptualized as a cohesive moral perspective grounded in a combination of secular and Christian moral requirements—on two fronts. First, I critique his view of the moral demands of justice within a secular pluralistic society by showing how Thomistic natural law theory provides a content-full theory of human flourishing that is rationally articulable and defensible as a canonical vision of the good, even if it is not universally recognized as such. Second, I defend the principles (...) of Roman Catholic social teaching (RCST) against Engelhardt’s objection that it constitutes a watered-down version of the Christian moral vision which opens the door to intolerable moral compromises. While I acknowledge that Engelhardt’s criticism of RCST is well-grounded in certain abusive compromises that have been made by some Catholic healthcare institutions, I contend that such abuses are not endemic to RCST and avoidance of them is practically feasible in contemporary secular pluralistic societies. My primary aim is to show how continued dialogue between Engelhardtian libertarians and more communitarian-inclined RCST proponents may constructively yield a vision of healthcare allocation that ensures succor for the least advantaged within an authentically Christian social ethic.

Recent debate among bioethicists concerns the potential to enhance human beings’ physical or cognitive capacities by means of genetic, pharmacological, cybernetic, or surgical interventions. Between “transhumanists,” who argue for unreserved enhancement of human capabilities, and “bioconservatives,” who warn against any non-therapeutic manipulation of humanity’s natural condition, lie those who support limited forms of enhancement for the sake of individual and collective human flourishing. Many scholars representing these views also share a concern over the status and interests of human beings with (...) various types of cognitive and physical disabilities, some of which may be ameliorable by enhancement interventions. The question addressed in this paper is whether valuing the enhancement of human capabilities may be reconciled with valuing the existence and phenomenological experiences of human beings with various disabilities. Can we value enhanced capabilities without disvaluing those whose capabilities fall below a defined threshold of “normal function”? Furthermore, if certain forms of disability, particularly cognitive disabilities, negatively impact one’s flourishing, could the enhancement of one’s cognitive capacities through biotechnological means enhance one’s flourishing.
