IN THIS PAPER, I PROVIDE A FORMULATION of Thomas Aquinas’s account of the nature of human beings for the purpose of comparing it with other accounts in both the history of philosophy and contemporary analytic philosophy. I discuss how his apparently dualistic understanding of the relationship between soul and body yields the conclusion that a human being exists as a unified substance composed of a rational soul informing, that is, serving as the specific organizing principle of, a physical body. I further address the issue of Aquinas’s contention that a human rational soul can exist without being united to a body and show how this ability of a human soul does not contradict the thesis that a human being exists naturally as embodied. I will also respond to two related questions. First, what accounts for the individuation of human beings as distinct members of the human species? Second, what is the principle of identity by which a human being persists through time and change?

Discussions concerning whether there is a natural right to health care may occur in various forms, resulting in policy recommendations for how to implement any such right in a given society. But health care policies may be judged by international standards including the UN Universal Declaration of Human Rights. The rights enumerated in the UDHR are grounded in traditions of moral theory, a philosophical analysis of which is necessary in order to adjudicate the value of specific policies designed to enshrine rights such as a right to health care. We begin with an overview of the drafting of the UDHR and highlight the primary influence of natural law theory in validating the rights contained therein. We then provide an explication of natural law theory by reference to the writings of Thomas Aquinas, as well as elucidate the complementary “capabilities approach” of Martha Nussbaum. We conclude that a right to health care ought to be guaranteed by the state.

Kevin O’Rourke argues that Aquinas’s concept of a “spiritual goal of life,” to which Pius XII refers in his famous allocution of 1957, serves as a basis for declaring that certain treatments, such as artificial nutrition and hydration [ANH] for patients in a persistent vegetative state [PVS], are “extraordinary” and thus morally optional. I examine whether O’Rourke properly interprets Aquinas’s concept in this regard and conclude that he is correct in his assessment and that ANH is properly understood, in typical and properly diagnosed cases of PVS, as extraordinary treatment the use of which is not morally obligatory.

I investigate Thomas Aquinas's metaphysical account of human death, which is defined in terms of a rational soul separating from its material body. The question at hand concerns what criterion best determines when this separation occurs. Aquinas argues that a body has a rational soul only insofar as it is properly organised to support the soul's vegetative, sensitive, and rational capacities. According to the ‘higher‐brain’ concept of death, when a body can no longer provide the biological foundation necessary for the operation of conscious rational thought and volition, a substantial change occurs in which the rational soul departs and the body left behind is a ‘humanoid animal’ or a mere ‘vegetable.’I argue that the separation of soul and body does not occur until the body ceases to function as a unified, integrated organism. A rational soul is not only the seat of a human being's rational capacities; it is also the principle of the body's sensitive and vegetative capacities. Since Aquinas defines a human being as a composite of soul and body, and not with merely the exercise of rational capacities, the determination of death requires incontrovertible evidence that the body has ceased all the operations that correspond to the soul's proper capacities. The evidence of this is the body's loss of its integrative organic unity and the criterion for determining when this loss occurs is the irreversible cessation of whole‐brain functioning.

Philosophy and space travel are characterized by the same fundamental purpose: exploration. An essential guide for both philosophers and Trekkers, Star Trek and Philosophy combines a philosophical spirit of inquiry with the beloved television and film series to consider questions not only about the scientific prospects of interstellar travel but also the inward journey to examine the human condition. The expansive topics range from the possibilities for communication among different cultural backgrounds to questions about the stoic temperament exhibited by Vulcans to Ferengi business practices. Specifically chosen to break new ground in exploring the philosophical dimensions of Star Trek, these articles boldly go where no philosopher has gone before.

Eleonore Stump provides a clear and thorough treatment of some of the main philosophical themes that characterize Aquinas’s vast corpus in a way that allows his thought to be situated among contemporary philosophers and their ideas. This approach allows Stump to address certain criticisms that have been raised against Aquinas’s views as well as the medieval Christian approach to philosophy in general. The proper consideration owed to Aquinas as a key figure in the history of philosophy is given sound support by Stump’s exhaustive illumination of his views, the details of which are not fully appreciated in some more traditional renderings of his philosophy.

One of Thomas Aquinas’s primary philosophical concerns is to provide an account of the nature of a human soul. He bases his account on Aristotle’s De anima, wherein Aristotle gives an account of “soul” (psuchē) as divided into three distinct types: vegetative, sensitive, and intellective. Aristotle defines an intellective soul as proper to human beings and the only type of soul that may potentially exist separated from a material body. Aquinas argues that an intellective soul is indeed separable from its body and conceives of it as essentially, or unqualifiedly (simpliciter), immortal and separable from its body, and relatively (secundum quid) mortal and conjoined to its body. Pietro Pomponazzi (1462-1525), a Renaissance philosopher concerned with ridding neo-Aristotelianism of Platonic or Averroistic influences, criticizes Aquinas’s account as not being properly Aristotelian and having been influenced by Platonism. In this paper, I will present summaries of Aquinas’s arguments concerning an intellective soul’s essential immortality, as well as Pomponazzi’s criticisms of Aquinas’s position. I then propose ways in which Aquinas may respond to these criticisms.

Thomas Aquinas argues that matter is informed by a rational soul to compose a human person. But a person may survive her body’s death since a rational soul is able to exist and function without matter. This leads to the typical characterization of Aquinas as a dualist. Thomistic dualism, however, is distinct from both Platonic dualism and various accounts of substance dualism offered by philosophers such as Richard Swinburne. For both Plato and Swinburne, a person is identical to an immaterial soul that is contingently related to a human body. For Aquinas, a human person is composed of her soul and the matter it informs, but is not identical to either metaphysical component. I explicate Thomistic dualism while critically analyzing Swinburne’s account. I conclude that Aquinas’s account has theresources to address a central issue that arises for substance dualism.

Debate concerning human enhancement often revolves around the question of whether there is a common “nature” that all human beings share and which is unwarrantedly violated by enhancing one’s capabilities beyond the “species-typical” norm. I explicate Thomas Aquinas’s influential theory of human nature, noting certain key traits commonly shared among human beings that define each as a “person” who possesses inviolable moral status. Understanding the specific qualities that define the nature of human persons, which includes self-conscious awareness, capacity for intellective thought, and volitional autonomy, informs the ethical assessment of various forms of enhancement. Some forms of cognitive and physical enhancement may be desirable from the perspective of what constitutes the “flourishing” of human persons in our fundamental nature; while other forms of enhancement, such as emotive or so-called “moral” enhancement, run the risk of detracting from human flourishing when evaluated from the virtue-theoretic perspective Aquinas promotes

Those who oppose human embryonic stem cell research argue for a clear position on the metaphysical and moral status of human embryos. This position does not differ whether the embryo is present inside its mother’s reproductive tract or in a cryopreservation tank. It is worth examining, however, whether an embryo in “suspended animation” has the same status as one actively developing in utero. I will explore this question from the perspective of Thomas Aquinas’s metaphysical account of human nature. I conclude that a cryopreserved human embryo counts, both metaphysically and morally, as a person; and thus the utilization of such embryos for inherently destructive research purposes is impermissible.

Advocates of active euthanasia and physician-assisted suicide argue that a patient’s intractable pain and suffering are a sufficient justification for his life to end if he autonomously so chooses. Others hold that the non-utilization of life-sustaining treatment, the use of pain-relieving medication that may hasten a patient’s death, and palliative sedation may be morally acceptable means of alleviating pain and suffering. How a patient should be cared for when approaching the end of life involves one’s core religious and moral values, particularly concerning whether pain and suffering can have some sort of instrumental value. The author reasons why a patient who is terminally ill can find his suffering valuable for both religious and nonreligious goals. National Catholic Bioethics Quarterly 12.2 (Summer 2012): 251–261.

This essay focuses on cases in which a physician elects to withhold, either temporarily or permanently, certain information from a patient for arguably beneficent reasons. That is, the physician is not being self-serving, to herself or her institution, by not revealing this information. Rather, the goal is purely to promote what the physician believes to be in the patient’s best interest by withholding information that may be harmful to him. This practice of informational guardianship is known as the “therapeutic privilege.” This discussion is thus also limited to clinical interactions and not explicitly discuss withholding information from research subjects, which raises distinct ethical issues and elicits different reasons used to justify or nullify the moral permissibility of nondisclosure.

Alongside a revival of interest in Thomism in philosophy, scholars have realised its relevance when addressing certain contemporary issues in bioethics. This book offers a rigorous interpretation of Aquinas's metaphysics and ethical thought, and highlights its significance to questions in bioethics. Jason T. Eberl applies Aquinas’s views on the seminal topics of human nature and morality to key questions in bioethics at the margins of human life – questions which are currently contested in the academia, politics and the media such as: When does a human person’s life begin? How should we define and clinically determine a person’s death? Is abortion ever morally permissible? How should we resolve the conflict between the potential benefits of embryonic stem cell research and the lives of human embryos? Does cloning involve a misuse of human ingenuity and technology? What forms of treatment are appropriate for irreversibly comatose patients? How should we care for patients who experience unbearable suffering as they approach the end of life? _Thomistic Principles and Bioethics_ presents a significant philosophical viewpoint which will motivate further dialogue amongst religious and secular arenas of inquiry concerning such complex issues of both individual and public concern.
