From the time of Locke, discussions of personal identity have often ignored the question of our basic metaphysical nature: whether we human people are biological organisms, spatial or temporal parts of organisms, bundles of perceptions, or what have you. The result of this neglect has been centuries of wild proposals and clashing intuitions. What Are We? is the first general study of this important question. It beings by explaining what the question means and how it differs from others, such as (...) questions of personal identity and the mind-body problem. It then examines in some depth the main possible accounts of our metaphysical nature, detailing both their theoretical virtues and the often grave difficulties they face. The book does not endorse any particular account of what we are, but argues that the matter turns on more general issues in the ontology of material things. If composition is universal--if any material things whatever make up something bigger--then we are temporal parts of organisms. If things never compose anything bigger, so that there are only mereological simples, then we too are simples--perhaps the immaterial substances of Descartes--or else we do not exist at all (a view Olson takes very seriously). The intermediate view that some things compose bigger things and others do not leads almost inevitably to the conclusion that we are organisms. So we can discover what we are by working out when composition occurs. (shrink)

"Williams's masterful translation satisfies (at last!) a long-standing need. There are lots of good translations of Augustine's great work, but until now we have been forced to choose between those that strive to replicate in English something of the majesty and beauty of Augustine's Latin style and those that opt instead to convey the careful precision of his philosophical terminology and argumentation. Finally, Williams has succeeded in capturing both sides of Augustine's mind in a richly evocative, impeccably reliable, elegantly readable (...) presentation of one of the most impressive achievements in Western thought--Augustine's Confessions." --Scott MacDonald, Professor of Philosophy and Norma K.

The therapy-enhancement distinction occupies a central place in contemporary discussions of human genetics and has been the subject of much debate. At a recent conference on gene therapy policy, scientists predicted that within a few years researchers will develop techniques that can be used to enhance human traits. In thinking about the morality of genetic interventions, many writers have defended somatic gene therapy, and some have defended germline gene therapy, but only a handful of writers defend genetic enhancement, or even (...) give it a fair hearing. The mere mention of genetic enhancement makes many people cringe and brings to mind the Nazi eugenics programs, Aldous Huxley's BraveNewWorld, or the recent movie Although many people believe that gene therapy has morally legitimate medical uses, others regard genetic enhancement as morally problematic or decidedly evil.

Persons and Bodies develops and defends an account of persons and of the relation between human persons and their bodies. Human persons are constituted by bodies, without being identical to the bodies that constitute them—just as, I argue, statues are constituted by pieces of bronze, say, without being identical to the pieces of bronze that constitute them. The relation of constitution, therefore, is not peculiar to persons and their bodies, but is pervasive in the natural world.

How should we morally evaluate protocols to edit the human genome? In this essay, the author argues that the therapy–enhancement distinction commonly used in debates over genetic engineering is not a robust one. Using the example of lipid-lowering pharmacological interventions, he argues that a strong case can be made for the morality of therapeutic enhancements that blur the distinction between therapy and enhancement. He proposes, therefore, that the therapy–enhancement distinction should be replaced by a therapy–nontherapy distinction that acknowledges that some (...) beneficial and morally acceptable therapies are enhancements. However, the benefits–burdens distinction should also be deployed, as it commonly is with other technologies that affect the human person, alongside the therapy–nontherapy distinction, to judge whether a particular technological intervention to edit an individual’s genome should be permitted or not. Gene editing to make patients healthier than healthy should be allowed. (shrink)

In The Emergent Self, William Hasker joins one of the most heated debates in contemporary analytic philosophy, that over the nature of mind.

Challenging, with several powerful arguments, some of our deepest beliefs about rationality, morality, and personal identity, Parfit claims that we have a false view about our own nature. It is often rational to act against our own best interersts, he argues, and most of us have moral views that are self-defeating. We often act wrongly, although we know there will be no one with serious grounds for complaint, and when we consider future generations it is very hard to avoid conclusions (...) that most of us will find very disturbing.

I approach the subject of human enhancement—whether by genetic, pharmacological, or technological means—from the perspective of Thomistic/Aristotelian philosophical anthropology, natural law theory, and virtue ethics. Far from advocating a restricted or monolithic conception of “human nature” from this perspective, I outline a set of broadly-construed, fundamental features of the nature of human persons that coheres with a variety of historical and contemporary philosophical viewpoints. These features include self-conscious awareness, capacity for intellective thought, volitional autonomy, desire for pleasurable experiences, and the (...) necessity of healthy biological functioning. On this basis, I contend that there may be legitimate forms of human enhancement for specific purposes related to the physical, cognitive, and emotive dimensions of human existence. However, wider philosophical considerations call into question whether societal attitudes towards enhancement and the differences that may emerge between those who are enhanced versus the unenhanced may raise insurmountable questions of justice, as well as a loss of virtues associated with what Alasdair MacIntyre refers to as our “acknowledged dependency.” This presentation will navigate towards conclusions differentiating principled from practical objections to specific forms of, and means towards achieving, enhancement of certain human capacities. While critical of some forms of human enhancement, I nevertheless argue that other forms of enhancement are, in principle, morally permissible—and for which any practical concerns may be surmountable—insofar as they positively support human flourishing according to our nature as living, sentient, social, and rational animals.

A controversial scientific vision predicts a time in which humans and machines will merge and create a new form of non-biological intelligence, explaining how the occurrence will solve such issues as pollution, hunger, and aging.

The rapid advancement of technology has led to an explosion of speculative theories about what the future of humankind may look like. These "technological futurisms" have arisen from significant advances in the fields of nanotechnology, biotechnology and information technology and are drawing growing scrutiny from the philosophical and theological communities. This text seeks to contextualize the growing literature on the cultural, philosophical and religious implications of technological growth by considering technological futurisms such as transhumanism in the context of the long (...) historical tradition of technological dreaming. Michael Burdett traces the latent religious sources of our contemporary technological imagination by looking at visionary approaches to technology and the future in seminal technological utopias and science fiction and draws on past theological responses to the technological future with Pierre Teilhard de Chardin and Jacques Ellul. Burdett's argument arrives at a contemporary Christian response to transhumanism based around the themes of possibility and promise by turning to the works of Richard Kearney, Eberhard Jüngel and Jürgen Moltmann. Throughout, the author highlights points of correspondence and divergence between technological futurisms and the Judeo-Christian understanding of the future. (shrink)

What makes us human? Richard Swinburne presents new philosophical arguments, supported by modern neuroscience, for the view that we are immaterial souls sustained in existence by our brains.

This volume comprises various viewpoints representing a Catholic perspective on contemporary practices in medicine and biomedical research. The Roman Catholic Church has had a significant impact upon the formulation and application of moral values and principles to a wide range of controversial issues in bioethics. Catholic leaders, theologians, and bioethicists have elucidated and marshaled arguments to support the Church’s definitive positions on several bioethical issues, such as abortion, euthanasia, and reproductive cloning. Not all bioethical issues, however, have been definitively addressed (...) by Catholic authorities, and some Church teachings allow for differing applications in diverse circumstances. Moreover, as new biomedical technologies emerge, Church authorities rely on experts in science, medicine, philosophy, theology, law, and other disciplines to advise them. Such experts continue to debate issues related to reproduction, genetics, end-of-life care, and health care policy. This volume will be a valuable resource for scholars in bioethics or Catholic studies, who will benefit from the nuanced arguments offered based on the latest research. This volume is also instructive for students entering the field to become aware of the founding philosophical and theological principles informing the Catholic bioethical worldview. (shrink)

Thomas Aquinas asked the essential philosophical question which continues to resound to the modern day: what constitutes a human being? This volume looks at Aquinas's views on bodily and spiritual identity through a lens of theological concerns, pagan and Arabic authoritative sources, and contemporary polemic with dualist heresy.

This series offers central philosophical treatises of Aquinas in new, state-of-the-art translations distinguished by their accuracy and use of clear and nontechnical modern vocabulary. Annotation and commentary accessible to undergraduates make the series an ideal vehicle for the study of Aquinas by readers approaching him from a variety of backgrounds and interests.

This article explores the way the distinction between enhancement and therapy has been used in Catholic bioethics to assess the moral character of technologies that developments in genetics and neuroscience have made possible. The purpose of drawing lines between therapy and enhancement is typically to claim that the former is always ethically justified and the latter is morally suspect, if not altogether impermissible. The author connects the enhancement versus therapy distinction to concepts of human nature that ground it and examines (...) the function of the distinction in these theological anthropologies. She argues that the distinction is insufficient for making decisions regarding use of neurotechnologies. Catholic ethicists thus need to explore alternative methods to begin the essential project of developing neuroethics. National Catholic Bioethics Quarterly 15.1 : 63–72. (shrink)

What does it mean to say that this person at this time is 'the same' as that person at an earlier time? If the brain is damaged or the memory lost, how far does a person's identity continue? In this book two eminent philosophers develop very different approaches to the problem.

An argument in the cognitive enhancement literature is that using stimulants in populations of healthy but socially disadvantaged individuals mistakenly attributes pathology to nonpathological individuals who experience social inequalities. As the argument goes, using stimulants as cognitive-enhancing drugs to solve the social problem of poorly educated students in inadequate schools misattributes the problem as an individual medical problem, when it is really a collective sociopolitical problem. I challenge this argument on the grounds that not all types of enhancement have to (...) be explained in medical terms, but rather at least one conception of enhancement can be explained in social terms—opportunity maintenance. Therefore, I propose that as a moral requirement we ought to explore whether stimulants could be a means of remedying underprivileged children's experiences of social inequalities that are borne from inadequate schools for the sake of increasing their chances for opportunities and well-being.

Although there is some consonance in the language of transcendence between proponents of the Catholic faith and of human biotechnological enhancement, their goals are incommensurate. Nevertheless, consistent with the valuation of the body as integral to the human person, Catholic culture has in fact proven to be a fruitful context for developing external therapeutic HBEs. Catholic perspectives on internal HBEs, especially in the context of ‘transhumanism’, are, by contrast, neither clear-cut nor easy to establish. A prerequisite for progress is to (...) understand what is meant by flourishing in a Catholic worldview, the root metaphor of which is second-person relatedness to God, culminating in divine friendship. Hence important measures of success of internal HBEs will include sustaining, or at least not impeding, thoughtful attention and the capacity to receive experiences that can sanctify the mind.

The phrase "playing God" so popular with journalists takes on a serious meaning in the debate over germline genetic intervention. While guarding against the dangers of human pride implied in the phrase "playing God," special attention is given here to the Christian concept of the human being as created in the divine image, the imago dei . Human beings are dubbed "created cocreators." In this light ethical arguments proscribing germline intervention are examined and refuted, leaving the door open for creative (...) responsibility on the part of the present generation for our future progeny.

This paper is about the neglected question of what sort of things we are metaphysically speaking. It is different from the mind-body problem and from familiar questions of personal identity. After explaining what the question means and how it differs from others, the paper tries to show how difficult it is to give a satisfying answer.

A comprehensive study of the ethics of killing in cases in which the metaphysical or moral status of the individual killed is uncertain or controversial. Among those beings whose status is questionable or marginal in this way are human embryos and fetuses, newborn infants, animals, anencephalic infants, human beings with severe congenital and cognitive impairments, and human beings who have become severely demented or irreversibly comatose. In an effort to understand the moral status of these beings, this book develops and (...) defends distinctive accounts of the nature of personal identity, the evaluation of death, and the wrongness of killing. The central metaphysical claim of the book is that we are neither nonmaterial souls nor human organisms but are instead embodied minds. In ethical theory, one of the central claims is that the morality of killing is not unitary; rather, the principles that determine the morality of killing in marginal cases are different from those that govern the killing of persons who are self‐conscious and rational. Another important theme is that killing in marginal cases should be evaluated in terms of the impact it would have on the victim at the time rather than on the value of the victim's life as a whole. What primarily matters is how killing would affect that which would be rational for the victim to care about at the time of death. By appealing to various foundational claims about identity, death, and the morality of killing, this book yields novel conclusions about such issues as abortion, prenatal injury, infanticide, the killing of animals, the significance of brain death, the termination of life support in cases of persistent vegetative state, the use of anencephalic infants as sources of organs for transplantation, euthanasia, assisted suicide, and advance directives in cases of dementia. In particular, the book defends the moral permissibility of abortion, infanticide, and euthanasia in certain cases and argues that brain death is not the appropriate criterion of death either for a person or a human organism.

Theologies of human nature routinely reflect the insights of evolutionary biology, for which human biological nature is variable, changing and indeterminate in its boundaries with other living things. However, these theologies do not yet reflect what biotechnology discloses about human biological nature, namely, that it is malleable and indeterminate in its boundaries with machines. Does respect for human biological nature as created by God, or protection of the human person whose nature it is, require us to refrain from taking advantage (...) of its malleability and indeterminacy to select or design functions and traits? Or should we welcome malleability and indeterminacy as conditions for us to fulfill a vocation to determine our nature or bring it to perfection? And do malleability and indeterminacy render obsolete the notion that we look to our nature to determine what our good is? This article answers these questions. (shrink)

Does human nature possess normative significance? If so, what is it and what implications does it have for biotechnology? This essay critically examines three answers to these questions. One answer focuses on human nature as the ground of natural goods or goods dependent on human nature, another answer finds normative significance in the indeterminacy or malleability of human nature, and a third answer treats human nature as a natural sign of divine grace. Kathryn Tanner, who offers the second answer, and (...) Karl Barth, who offers the third, deny that nature has normative status in itself, apart from grace, but differ over the relation of grace to human nature as created. While indebted to Tanner, this essay favors Barth’s view as best suited to a Christian ethics of biotechnology. (shrink)

Starting from research on biotechnology and its applications to living organisms, this paper presents the key features of modern-day synthetic biology, as well as its main ethical implications. The analysis of the paradox of the concept of robustness in the creation of microorganisms through synthetic biology leads us to address the topic of vulnerability, applied to man, but also to all other living beings. The concept of “enhanced human being” will strengthen the link between complexity and vulnerability as inherent features (...) of living beings. Reflecting upon the importance of considering vulnerability applied to man’s three-fold dimensions - physical, psycho-social and spiritual - and their interaction with their environment, we will define a type of anthropology which may constitute the basis of the study on the ethical implications of synthetic biology. This will lead to present the purpose of an ethical limit to the temptation of « allmightiness », which the concept of enhanced human being could entail, and vulnerability as a defining feature of all living beings.

Distinctions between therapy and enhancement are difficult to draw with precision, especially in marginal cases. Nevertheless, most recent Christian discussions of enhancement technologies accept the general plausibility of distinctions drawn between therapeutic interventions and enhancement technologies by appealing to general understandings of nature and human nature as available benchmarks. On that basis, a range of religious assessments of enhancement technologies can be identified. Those judgments incorporate different interpretations of nature as a source of moral insight, different understandings of human responsibility (...) in light of God's purposes, and different assessments of the effects of sin and finitude on human freedom.

Discussions of genetic enhancements often imply deep suspicions about human desires to manipulate or enhance the course of our future. These unspoken assumptions about the arrogance of the quest for perfection are at odds with the normally hopeful resonancy we find in contemporary theology. The author argues that these fears, suspicions and accusations are misplaced. The problem lies not with the question of whether we should pursue perfection, but rather what perfection we are pursuing. The author argues that perfection, properly (...) understood, has an enormously positive function in the Roman Catholic tradition. The author examines three sources: the Scriptures, the scholastic tradition, and ascetical theology. He examines contemporary criticisms of perfectionism and suggests that an adequate virtue theory keeps us from engaging perfectionism as such. The author then shows how a positive, responsible view of perfection is an asset to our discussion on enhancement technology. (shrink)

Theories of social justice are necessarily abstract, reaching beyond the particular and the immediate to the general and the timeless. Yet such theories, addressing the world and its problems, must respond to the real and changing dilemmas of the day. A brilliant work of practical philosophy, Frontiers of Justice is dedicated to this proposition. Taking up three urgent problems of social justice neglected by current theories and thus harder to tackle in practical terms and everyday life, Martha Nussbaum seeks a (...) theory of social justice that can guide us to a richer, more responsive approach to social cooperation. The idea of the social contract--especially as developed in the work of John Rawls--is one of the most powerful approaches to social justice in the Western tradition. But as Nussbaum demonstrates, even Rawls's theory, suggesting a contract for mutual advantage among approximate equals, cannot address questions of social justice posed by unequal parties. How, for instance, can we extend the equal rights of citizenship--education, health care, political rights and liberties--to those with physical and mental disabilities? How can we extend justice and dignified life conditions to all citizens of the world? And how, finally, can we bring our treatment of nonhuman animals into our notions of social justice? Exploring the limitations of the social contract in these three areas, Nussbaum devises an alternative theory based on the idea of capabilities. She helps us to think more clearly about the purposes of political cooperation and the nature of political principles--and to look to a future of greater justice for all. (shrink)

Response to human head transplant proposal and pertinent personal identity questions.

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.

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.

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.

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.

In this book, Ted Peters explores the fallacies of the "gene myth" and presents a resounding array of arguments against this kind of all-encompassing genetic determinism. On the scientific side, he correctly points out that genetic influences on behavior are in most instances relatively modest. Does anyone deny that identical twins are still able to practice individual free will? After dispatching some of the sweepingly deterministic conclusions of the "science" of evolutionary psychology with a particularly effective set of rebuttals, Peters (...) arrives at the conclusion that the nature of humanness is an interaction of three things- not one, not two, but three: genetics, environment, and free will. Neglecting any one of these three leads down a path of fuzzy thinking and dangerous consequences. (shrink)

This new translation of Thomas Aquinas’s most important study of Aristotle casts bright light on the thinking of both philosophers. Using a new text of Aquinas’s original Latin commentary, Robert Pasnau provides a precise translation that will enable students to undertake close philosophical readings. He includes an introduction and notes to set context and clarify difficult points as well as a translation of the medieval Latin version of Aristotle’s _De anima _ so that readers can refer to the text Aquinas (...) had at hand. In his _De anima commentary_, Aquinas offers the first and most original of his studies of Aristotle. His influential, cogent reading of Aristotle’s notoriously difficult text not only contributes to our understanding of the Greek philosopher but also expresses in full detail Aquinas’s own views on central philosophical topics. Writing at the height of his intellectual powers, Aquinas considers in full detail the nature of the soul, the mind-body problem, the role of the intellect, the character of sensation, and many other related issues.
