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

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.

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.

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.

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

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.

In debates over issues such as abortion, a primary principle on which the Roman Catholic outlook is based is the natural law mandate to respect human life rooted in the Aristotelian philosophy of Thomas Aquinas. This principle, however, is limited by focusing on the obligation not to kill innocent humans and thereby neglects another important facet of the Aristotelian-Thomistic ethical viewpoint—namely, obligations that bind human beings in relationships of mutual dependence and responsibility. I argue that there is a need to cultivate a “virtue of acknowledged responsibility” and conclude by addressing a prevalent issue in contemporary society: absent paternal responsibility. My aim is to show that there is an interesting and often neglected rationale in Catholic moral understanding for “deadbeat dad” laws that compel men to take responsibility for any children or fetuses they father and to assist women who give birth to those children or carry those fetuses.

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.

The essays in this volume tackle the philosophical questions from these blockbuster films including: Was Anakin predestined to fall to the Dark Side? Are the Jedi truly role models of moral virtue? Why would the citizens and protectors of a democratic Republic allow it to descend into a tyrannical empire? Is Yoda a peaceful Zen master or a great warrior, or both? Why is there both a light and a dark side of the Force? Star Wars and Philosophy ponders the depths of these subjects and asks what it truly means to be mindful of the "living force."

Dignitas personae has garnered significant attention both inside and outside Roman Catholic circles, but it lacks the argumentative force not only to present the Church’s ethical judgment but also to persuade non-sympathetic readers. More direct engagement with contrary views would provide a stronger foundation for constructing arguments in public discourse. This article highlights various assertions found in Dignitas personae which call for greater explicit argumentation. Subjects treated include the ontological and moral status of human embryos, prenatal adoption, potentially abortifacient contraceptives, reproductive cloning, and alternatives to human embryonic stem cell research, such as induced pluripotent stem cells and animal–human chimeras.

Euthanasia, today, is one of the most debated issues in bioethics. Euthanasia, at the time of Thomas Aquinas, was an unheard-of term. Nevertheless, while there is no direct statement with respect to “euthanasia” per se in the writings of Aquinas, Aquinas’s moral theory and certain theological commitments he held could be applied to the euthanasia question and thus bring Aquinas into contemporary bioethical debate. In this paper, I present the relevant aspects of Aquinas’s account of natural law and his theological views on suffering, examining what conclusions each entails with respect to directly intended euthanasia. I then proceed to discuss cases that involve either the administration of palliative medication that hastens death, terminal sedation, or the non-utilization of life-sustaining treatment. This involves a detailed investigation into Aquinas’s account of human intentional action and the question of whether Aquinas holds some form of the Principle of Double-Effect. I end with a final statement of Aquinas’s position on these various types of cases as a synthesis of the conclusions drawn from the different areas of his thought discussed in this paper. My aim is to provide a set of guidelines, based upon Aquinas’s thought, for those who may be faced with decisions regarding the proper form of palliative treatment to be provided to those suffering from a painful terminal illness. Decision-makers, in such cases, may include a terminally ill patient, a patient’s immediate family, health care providers, and lawmakers concerned with establishing the legality of certain forms of treatment. Establishing a clear set of moral guidelines, specifically addressed to this type of decision, can assist the relevant decision-makers in forming their consciences such that they may take the appropriate course of action in confronting the suffering of a terminally ill patient.
