Human Genetic Modification

What are the ethical implications of our use of new methods and tools for reading and recoding our genetic information? What is the state of our knowledge of the human genome, including the connection between certain genes and diseases? What are some possible moral guidelines for fiddling around with the immense genetic archive within each of us? Do we - as individuals and as a species - have the right to do so? With Peter Keating and Rhoda Perozzi.

Recently, Brummett and Crutchfield advanced two critiques of theists who object to moral enhancement. First, a conceptual critique: theists who oppose moral enhancement commonly do so because virtue is thought to be acquired only via a special kind of process. Enhancement does not involve such processes. Hence, enhancement cannot produce virtue. Yet theists also commonly claim that God is perfectly virtuous and not subject to processes. If virtue requires a process and God is perfectly virtuous without a process, however, then (...) theists contradict themselves. Second, a moral critique: theists who reject moral enhancement are selfish, since accepting moral enhancement would (allegedly) reduce widespread suffering. Theists often condemn selfishness, however. By condemning selfishness and (simultaneously) rejecting enhancement, therefore, theists contradict themselves yet again. We argue that both critiques fail. Both substantially misrepresent their target. First, Brummett and Crutchfield confuse metaphysical enhancement (attempts to alter human nature) with moral enhancement (attempts to become better human beings). Authors that Brummett and Crutchfield cite object to the former, not the latter. Second, both conceptual and moral critiques overlook the many resources within theistic traditions that can quickly resolve relevant (alleged) contradictions. The conceptual critique, for example, misrepresents both common views held among theists (regarding God’s virtue) and the ways in which virtue may be acquired. Similarly, the moral critique mischaracterizes the relationship commonly posited by theists between enhancement and agency. By attending to what theists actually claim—rather than relying on caricatures—it becomes clear that each of Brummett and Crutchfield’s critiques fail. (shrink)

The use of genome embryo editing tools in reproduction is often touted as a way to ensure the birth of healthy and genetically related children. Many would agree that this is a worthy goal. The purpose of this paper is to argue that, if we are concerned with justice, accepting such goal as morally appropriate commits one to rejecting the development of embryo editing for reproductive purposes. This is so because safer and more effective means exist that can allow many (...) more prospective parents to achieve the same valued goal and that offer additional benefits. (shrink)

Recent developments in genomic technology, especially those enabling gene editing, promise to put an end to hitherto intractable medical problems and to usher us into the age of personalized medicine. These technologies, however, raise a number of serious ethical challenges. Given the global impact of this technology, recent international regulations emphasize the need for intercultural dialogue on these ethical issues. This paper concentrates on Islamic perspectives on human genetic modification. It examines Islamic juristic discourses on the issue of genetic modification (...) and highlights the different layers within these discourses. The paper identifies the main positions regarding human genetic modification along with the underlying arguments for each of them. In general, these positions are articulated in light of the nature as well as the intended objectives of the different procedures. The paper devotes special attention to the treatment-enhancement distinction and argues that within Islamic discourses this distinction is quite nuanced. The paper points out important substantive and methodological gaps and emphasizes the evolving nature of Islamic discourses on this issue. (shrink)

Is it possible, ethically speaking, to create posthuman and transhuman persons from a religious perspective? Who is responsible for post and transhuman creation? Can post and transhuman persons be morally accountable? Addressing such pressing ethical questions around post and transhuman creation, this volume considers the philosophical and theological arguments that define and stimulate contemporary debate. Contributors consider the full implications of creating post and transhuman beings by highlighting the role of new technologies in shaping new forms of consciousness, as well (...) as the role the generators of post and transhuman beings play in such creation. They ask, what the relative power of such generators is, both in terms of society and in terms of their relationship to their creations. Appreciating how the lived realities of such beings will be constructed and legitimised in contemporary society adds further breadth to the wide-ranging consequences of post and transhuman creation explored. The collection's interdisciplinary approach traverses the philosophical writings of Aristotle, Aquinas, Kant, Nietzsche, and Heidegger, alongside theological considerations from the Christian, Islamic and Jewish traditions, inviting academics, faith leaders, policy makers, and practitioners to think through the ethical gamut of generating post and transhuman beings.

Deriving ethical conclusions from arguments that rely heavily on metaphysical foundations, as Parfit (1984) does in generating his Nonidentity Problem, is an approach fraught with problems. Sparrow...

In this commentary paper, we are taking one step further in questioning the central assumptions in the bioethical debates about reproductive technologies. We argue that the very distinction between “person affecting” and “identity affecting” interventions is based on a questionable form of material-origin essentialism. Questioning of this form of essentialist approach to human identity allows treating genome editing and genetic selection as more similar than they are taken to be in the standard approaches. It would also challenge the idea that (...) normative reasons we have in these two types of cases markedly differ in strength. (shrink)

This article responds to several liberal bioethicists’ criticisms of Jürgen Habermas’s The Future of Human Nature by placing it in the context of his intellectual influences and career-spanning theorization of communicative rationality. In particular, I argue that Habermas’s critics have not grasped his interpretation of Hannah Arendt’s concept of natality. Far from merely ventriloquizing his friend and teacher, Habermas distinguishes his construal of that concept from Arendt’s, which he presents as a naturalistic foil to his concerns about the potential ethical (...) impact of preimplantation genetic interventions. Whereas, according to Habermas, Arendt reasons directly from the biological fact of birth to the capacity for political action, he himself construes natality as implying a “divide between nature and culture” at the level of the “lifeworld.” Identifying Habermas’s interpretation of Arendt in this way explains why Habermas claims not to be a biological determinist and why the bioethicists’ criticism, according to which he is, fails.

Although legal personality has slowly begun to be granted to non-human entities that have a direct impact on the natural functioning of human societies (given their cultural significance), the same cannot be said for computer-based intelligence systems. While this notion has not had a significantly negative impact on humanity to this point in time that only remains the case because advanced computerised intelligence systems (ACIS) have not been acknowledged as reaching human-like levels. With the integration of ACIS in medical assistive (...) technologies such as companion robots and bionics, our legal treatment of ACIS must also adapt—least society faces legal challenges that may potentially lead to legally sanctioned discriminatory treatment. For this reason, this article exposes the complexity of normalizing definitions of “natural” human subjects, clarifies how current bioethical discourse has been unable to effectively guide ACIS integration into implanted and external artefacts, and argues for the establishment of legal delineations between various ACIS-human mergers in reference to legal protections and obligations internationally.

Since its advent in the 20th century, informed consent has become a cornerstone of ethical healthcare, and obtaining it a core obligation in medical contexts. In my dissertation, I aim to examine the theoretical underpinnings of informed consent and identify what values it is taken to protect. I will suggest that the fundamental motivation behind informed consent rests in something I’ll call bodily self-sovereignty, which I argue involves a coupling of two groups of values: autonomy and non-domination on the one (...) hand, and self-ownership and personal integrity on the other. I will then go on to consider two 'case studies' I take to shed light on what is at stake in securing informed consent - consent in psychiatrically ill populations, and consent to interventions that involve the modification of the genetic germline.

In a study drawing from both evolutionary biology and the social sciences, evidence and argument is assembled in support of the comprehensive appli- cation of selfish gene theory to the human population. With a focus on genes giving rise to characteristically-human cooperation (“cooperative genes”) in- volving language and theory of mind, one may situate a whole range of pat- terned behaviour—including celibacy and even slavery—otherwise seeming to present insuperable difficulties. Crucially, the behaviour which tends to propa- gate the cooperative genes (...) may be “at cost” to the genes of some who may be party to the cooperation itself. Explanatory insights are provided by Trivers’ parent-offspring conflict theory, Lack’s principle, and Hamilton’s kin selec- tion mechanism. A primary observation is that cooperation using language and theory of mind is itself interdependent with full human conceptualization of a world of objects and of themselves as embodied beings. Human capaci- ties inhering in, or arising out of, the ability to cooperate are also responsible for a vitally important long-term process, the domestication of animals and p- lants. The approach illuminates the difference between animal and human sexual behaviour, and the emergence of kinship systems. Again, recent pat- terns of population growth become much more explicable. It is argued that the gene is the single controlling replicator; the notion of the meme as a sec- ond independent replicator is flawed. (shrink)

In recent years, bioethical discourse around the topic of ‘genetic enhancement’ has become increasingly politicized. We fear there is too much focus on the semantic question of whether we should call particular practices and emerging bio-technologies such as CRISPR ‘eugenics’, rather than the more important question of how we should view them from the perspective of ethics and policy. Here, we address the question of whether ‘eugenics’ can be defended and how proponents and critics of enhancement should engage with each (...) other. (shrink)

Humanity's toolkit for altering the world we live in now includes CRISPR. Through an evolutionary process, bacteria acquired a way to protect themselves from an invading virus, making their immediate future more secure. In human hands, this powerful genome‐editing tool offers the potential to impact, at a breathtaking rate, not only our own evolutionary future, but the future of other life on this planet. Ethical concerns about altering genomes are not new, but the birth of two CRISPR gene‐edited babies last (...) year created a renewed urgency around navigating the future and the lack of an agreed‐upon map to guide us is distressing. The goal of this article is not to provide that map but to suggest two essential questions, drawn from the context of events surrounding CRISPR to date, that should guide its drafting—“Who do we trust?” and “When is it time to act?”—and to consider what Unitarian Universalism might contribute to answering those questions.

In a recent article, Marilyn Baffoe-Bonnie offers three arguments for conducting CRISPR/Cas9 biotechnology research to cure sickle-cell disease (SCD) based on addressing historical and current injustices in SCD research and care. I show that her second and third arguments suffer from roughly the same defect, which is that they really argue for something else rather than for conducting CRISPR/Cas9 research in particular. For instance, the second argument argues that conducting this gene therapy research would improve the relationship between SCD sufferers (...) (who are mostly of African descent) and health care providers. But really what is essential in improving this relationship is for those providers to genuinely care and be concerned, and this could be lacking even with the CRISPR research being done. Indeed, this relationship could be improved even without that research being done, as long as there is genuine concern. Thus, this argument actually argues for the need for genuine concern. As for the third argument, one (of two) problems arises because it claims that CRISPR research for SCD should be pursued because the benefits would be shared by even non-research-participants, as non-participants would be encouraged. However, this argues for any research for SCD, not for CRISPR research in particular. I conclude that a better justice-based argument will use only Baffoe-Bonnie’s first argument, which is based on historic neglect of an actual cure for SCD (going beyond merely management or transplant therapies).

Review of Francoise Baylis, Altered Inheritance: CRISPR and the Ethics of Human Genome Editing (2019).

It has recently been argued that reproductive genetic manipulation technologies like mitochondrial replacement and germline CRISPR modifications cannot be said to save anyone’s life because, counterfactually, no one would suffer more or die sooner absent the intervention. The present article argues that, on the contrary, reproductive genetic manipulations may be life-saving (and, from this, have therapeutic value) under an appropriate population health perspective. As such, popular reports of reproductive genetic manipulations potentially saving lives or preventing disease are not necessarily mistaken, (...) though such terminology still requires further empirical validation.

Questa è un'eccellente revisione delle interazioni gene/ambiente sul comportamento e, nonostante sia un po' datata, è una lettura facile e utile. Iniziano con studi gemelli che mostrano l'impatto travolgente della genetica sul comportamento. Notano gli studi sempre più noti di Judith Harris che estendono e riassumono i fatti che l'ambiente domestico condiviso non ha quasi alcun effetto sul comportamento e che i bambini adottati crescono fino ad essere diversi dai loro fratellastri e sorelle come le persone scelte a caso. Un (...) punto fondamentale che loro (e quasi tutti coloro che discutono di genetica comportamentale) non riescono a notare è che le centinaia (migliaia a seconda del tuo punto di vista) degli universali comportamentali umani, comprese tutte le basi delle nostre personalità, sono determinate al 100% dai nostri geni, senza variazioni nella normalità. Tutti vedono un albero come un albero e non come una pietra, cercano e mangiano cibo, si arrabbiano e geloso ecc. Quindi, quello di cui stanno parlando per lo più qui è quanto ambiente (cultura) può influenzare il grado in cui vengono mostrati i vari tratti, piuttosto che il loro aspetto. Infine, discutono di eugenetica nel solito modo politicamente corretto, non riuscendo a notare che noi e tutti gli organismi siamo i prodotti dell'eugenetica della natura e che i tentativi di sconfiggere la selezione naturale con la medicina, l'agricoltura e la civiltà nel suo complesso sono disastrosi per qualsiasi società che persiste nel farlo. Fino al 50% di tutte le concezioni, o circa 100 milioni/anno, finiscono in un aborto spontaneo precoce, quasi tutti senza che la madre ne sia a conoscenza. Questo abbattimento naturale dei geni difettosi guida l'evoluzione, ci mantiene relativamente geneticamente sani e rende possibile la società. La disgenica è sufficiente a distruggere la civiltà, ma la sovrappopolazione sarà doprima.

Dies ist eine ausgezeichnete Überprüfung der Gen-/Umgebungsinteraktionen auf das Verhalten und ist, obwohl sie etwas veraltet ist, eine einfache und lohnende Lektüre. Sie beginnen mit Zwillingsstudien, die den überwältigenden Einfluss der Genetik auf das Verhalten zeigen. Sie stellen die immer bekannter werdenden Studien von Judith Harris fest, die die Fakten erweitern und zusammenfassen, dass die gemeinsame häusliche Umgebung fast keinen Einfluss auf das Verhalten hat und dass adoptierte Kinder so anders wachsen als ihre Stiefbrüder und -schwestern wie zufällig ausgewählte Menschen. (...) Ein grundlegender Punkt, den sie (und fast alle, die über Verhaltensgenetik diskutieren) nicht zur Kenntnis nehmen, ist, dass die Hunderte (Tausende je nach Standpunkt) menschlicher Verhaltensuniversalen, einschließlich aller Grundlagen unserer Persönlichkeiten, zu 100% von unseren Genen bestimmt werden, ohne Variation in normalen Werten. Jeder sieht einen Baum als Baum und nicht als Stein, sucht und isst Nahrung, wird wütend und eifersüchtig usw. Worüber sie hier also meistens sprechen, ist, wie viel Umwelt (Kultur) das Ausmaß beeinflussen kann, in dem verschiedene Merkmale gezeigt werden, und nicht ihr Aussehen. Schließlich diskutieren sie die Eugenik in der üblichen politisch korrekten Weise, ohne festzustellen, dass wir und alle Organismen die Produkte der Eugenik der Natur sind und dass Versuche, die natürliche Selektion mit Medizin, Landwirtschaft und Zivilisation als Ganzes zu besiegen, für jede Gesellschaft, die dies weiterhin tut,katastrophalsind. Bis zu 50 % aller Empfängnisse oder etwa 100 Millionen pro Jahr enden in einer frühen spontanen Abtreibung, fast alle ohne Dassmund die Mutter. Diese natürliche Keulung defekter Gene treibt die Evolution an, hält uns relativ genetisch gesund und macht die Gesellschaft möglich. Dysgenös ist ausreichend, um die Zivilisation zu zerstören, aber Überbevölkerung wirdd o eszuerst.

In this paper, I will present the empirical version of the slippery slope argument (SSA) in the field of genome editing. According to the SSA, if we adopt germline manipulation of embryos we will eventually end up performing or allowing something morally reprehensible, such as new coercive eugenics. I will investigate the actual possibility of sliding towards eugenics: thus, I will examine enhancement and eugenics both in the classical and liberal versions, through the lens of SSA. In the first part, (...) I will discuss the classical eugenics from a historical perspective and conclude that classical eugenics is morally deplorable; but by currently accepting genome editing I argue that it is not possible to ‘slip’ into classical eugenics. Then, I will analyze liberal eugenics: I will consider Habermas’ and Sandel’s objections to liberal eugenics and genetic human enhancement. Subsequently, I will reply to these arguments affirming that, although it is not possible to refuse any form of genetic enhancement, liberal eugenics would not consider the principles of justice, non-maleficence, and non-instrumentalization; hence, it should be considered not morally acceptable. In addition, I will support the thesis according to which the possibility of relapsing into liberal eugenics is more likely than relapsing into classical eugenics. Then, I will present a strategy that, while avoiding falling into the undesirable scenarios related to SSA, still accepts some application of germline genome editing of embryos and gametes. In such a way, I will show that even if we accept the plausibility of a certain slip into an undesirable scenario, SSA does not offer conclusive reasons to forbid any use of germline genome editing technique in both therapeutic and enhancement fields.

The article by Conrad et al. (AJOB Neuroscience, 2019, 10:1) does not take into account another, still hypothetical, procedure for cognitive enhancement (CE) which would be appropriate to consider in the surveys, i.e. the possibility to genetically enhance the cognitive abilities of a future individual using genome editing techniques. In this case, the conclusions of the article in the context of the “self-others difference” and “safety/naturalness” would be questioned. In fact, the results of the hypothetical surveys with the variant “genome (...) editing” could be significantly different from those obtained in the survey proposed by the authors: an individual would decide not for himself, but for the CE in a future child. In light of these considerations, we hold that the article highlights just the attitudes toward the principle of autonomy and redistributive justice; however, by introducing the new hypothetical scenario of CE with genome editing the attitudes toward the principles of beneficence and non-instrumentalisation could also be appreciated. Special attention to future generations is necessary to inform potential CE public policy, though using genome editing to enhance cognition abilities is just a future hypothetical perspective.

We review the Nuffield Council on Bioethics 2018 report on germline gene editing and show how its shortcomings are part of an increasingly permissive climate among elite scientists that may well have emboldened the Chinese 'CRISPR babies' experiment. Without a robust and meaningful airing of the perils of human germline modification, these views are likely to encourage additional, more mainstream moves in the same dangerous direction.

In The Future of Human Nature, Jürgen Habermas raises the question of whether the embryonic genetic diagnosis and genetic modification threatens the foundations of the species ethics that underlies current understandings of morality. While morality, in the normative sense, is based on moral interactions enabling communicative action, justification, and reciprocal respect, the reification involved in the new technologies may preclude individuals to uphold a sense of the undisposability of human life and the inviolability of human beings that is necessary for (...) their own identity as well as for reciprocal relations. Engaging with liberal bioethics and Catholic approaches to bioethics, the article clarifies how Habermas’ position offers a radical critique of liberal autonomy while maintaining its postmetaphysical stance. The essay argues that Habermas’ approach may guide the question of rights of future generations regarding germline gene editing. But it calls for a different turn in the conversation between philosophy and theology, namely one that emphasizes the necessary attention to rights violations and injustices as a common, postmetaphysical starting point for critical theory and critical theology alike. In 2001, Jürgen Habermas published a short book on questions of biomedicine that took many by surprise.[1] To some of his students, the turn to a substantive position invoking the need to comment on a species ethics rather than outlining a public moral framework was seen as the departure from the “path of deontological virtue,”[2] and at the same time a departure from postmetaphysical reason. Habermas’ motivation to address the developments in biomedicine had certainly been sparked by the intense debate in Germany, the European Union, and internationally on human cloning, pre-implantation genetic diagnosis, embryonic stem cell research, and human enhancement. He turned to a strand of critical theory that had been pushed to the background by the younger Frankfurt School in favor of cultural theory and social critique, even though it had been an important element of its initial working programs. The relationship of instrumental reason and critical theory, examined, among others, by Max Horkheimer, Theodor W. Adorno, and Herbert Marcuse and taken up in Habermas’ own Knowledge and Interest and Theory of Communicative Action became ever-more actual with the development of the life sciences, human genome analysis, and genetic engineering of human offspring. Today, some of the fictional scenarios discussed at the end of the last century as “science fiction” have become reality: in 2018, the first “germline gene-edited” children were born in China.[3] Furthermore, the UK’s permission to create so-called “three-parent” children may create a legal and political pathway to hereditary germline interventions summarized under the name of “gene editing.”In this article, I want to explore Habermas’ “substantial” argument in the hope that philosophy and theology become allies in their struggle against an ever-more reifying lifeworld, which may create a “moral void” that would, at least from today’s perspective, be “unbearable”, and for upholding the conditions of human dignity, freedom, and justice. I will contextualize Habermas’ concerns in the broader discourse of bioethics, because only by doing this, his concerns are rescued from some misinterpretations.[1] Jürgen Habermas, The Future of Human Nature.[2] Ibid., 125, fn. 58. 8[3] Up to the present, no scientific publication of the exact procedure exists, but it is known that the scientist, Jiankui He, circumvented the existing national regulatory framework and may have misled the prospective parents about existing alternatives and the unprecedented nature of his conduct.

Current debate and policy surrounding the use of genetic editing in humans often relies on a binary distinction between therapy and human enhancement. In this paper, we argue that this dichotomy fails to take into account perhaps the most significant potential uses of CRISPR-Cas9 gene editing in humans. We argue that genetic treatment of sporadic Alzheimer’s disease, breast- and ovarian-cancer causing BRCA1/2 mutations and the introduction of HIV resistance in humans should be considered within a new category of genetic protection (...) treatments. We find that if this category is not introduced, life-altering research might be unnecessarily limited by current or future policy. Otherwise ad hoc decisions might be made, which introduce a risk of unforeseen moral costs, and might overlook or fail to address some important opportunities. (shrink)

What’s the basis for considering an egg donor a genetic parent but not a mitochondrial donor? I will argue that a closer look at the biological facts will not give us an answer to this question because the process by which one becomes a genetic parent, i.e., the process of reproduction, is not a concept that can be settled by looking. It is, rather, a concept in need of philosophical attention. The details of my argument will rest on recent developments (...) in biological technology, but the persuasiveness of my argument will turn on the history of another biological concept, death. Given some important similarities between the two concepts, the way in which ‘death’ evolved in the recent past can provide guidance on how we should think about ‘reproduction.’. (shrink)

Despite the advent of CRISPR, safe and effective gene editing for human enhancement remains well beyond our current technological capabilities. For the discussion about enhancing human beings to be worth having, then, we must assume that gene-editing technology will improve rapidly. However, rapid progress in the development and application of any technology comes at a price: obsolescence. If the genetic enhancements we can provide children get better and better each year, then the enhancements granted to children born in any given (...) year will rapidly go out of date. Sooner or later, every modified child will find him- or herself to be “yesterday’s child.” The impacts of such obsolescence on our individual, social, and philosophical self-understanding constitute an underexplored set of considerations relevant to the ethics of genome editing.

Imagine a world where everyone is healthy, intelligent, long living and happy. Intuitively this seems wonderful, albeit unrealistic. However, recent scientific developments in genetic engineering, namely CRISPR/Cas bring the question into public discourse, how the genetic enhancement of humans should be evaluated morally.

Proponents of moral enhancement believe that we should pursue and apply biotechnological means to morally enhance human beings, as failing to do so is likely to lead to humanity's demise. Unsurprisingly, these proposals have generated a substantial amount of debate about the moral permissibility of using such interventions. Here I put aside concerns about the permissibility of moral enhancement and focus on the conceptual and evidentiary grounds for the moral enhancement project. I argue that such grounds are quite precarious.

One of the most salient contemporary concerns in academic debates and pop culture alike is the extent to which new technologies may re-cast Homo sapiens. Species members may find themselves encased in a type of existence they deem to be wanting in comparison with their present form, even if the promised form was assured to be better. Plausibly, the concern is not merely fear of change or of the unknown, but rather it arises out of individuals’ general identification with what (...) they are and what their friends and family are. In altering that identity beyond a point, they lose it and thus lose themselves in a kind of living death. The three volumes analysed in this essay offer widely differing perspectives on the relations between humans and new technology. As the three works reviewed here together make clear, a whole, fully coherent, definitive work on the composite redesign of human nature (CROHN) still has yet to materialize. (shrink)

John Harris's influential work on human enhancement has advocated the development, use, and exchange of human enhancement technologies. The types of enhancements that are of interest are biomedical interventions that are used to improve human capacities beyond what is necessary to achieve or maintain health or "normal functioning". This new book is unique in Harris's body of work in that it takes a more cautious stance regarding moral enhancements than he has taken toward other forms of human enhancement, such as (...) cognitive enhancements. I examine and evaluate Harris's main arguments for this cautious stance. Two of the main issues that are discussed are: (1) whether it would be unethical for someone to use biomedical technologies to become less racist and (2) whether it would be unethical for someone to use biomedical technologies to reduce impulsive violent aggression.

This book provides an entry-level introduction to philosophical ethics, theories of moral reasoning, and selected issues in applied ethics. Chapter 1 describes the importance of philosophical approaches to ethical issues, the general dialectical form of moral reasoning, and the broad landscape of moral philosophy. Chapter 2 presents egoism and relativism as challenges to the presumed objectivity and unconditionality of morality. Chapters 3, 4 and 5 discuss utilitarianism, deontology, and virtue ethics, respectively. Each chapter begins with a general overview of the (...) characteristic theory of value and moral reasoning and proceeds to present a more refined account based on a prominent historical source (Mill, Kant, and Aristotle, respectively). It then discusses strengths and weaknesses of the theory from a contemporary perspective, including more recent developments, defenses, and critiques. Each chapter includes an appendix in which secondary, less prominent, or more complex issues are discussed. Chapters 6-9 address in detail a prominent area of applied ethics: 6. abortion, 7. assisted dying, 8. Biotechnology, 9. Animals and eating. Each of these chapters presents an introduction to the topic, including definitions, historical and contemporary developments and contexts, etc.; the various questions and issues involved; and an application of each theory from multiple points of view. Each chapter also includes a set of primary readings along with an extensive bibliography. Chapter 10 discusses four more areas of applied ethics: War, Torture, and Terrorism; Capital Punishment; Environmental Ethics; and Same-Sex Marriage. The treatment of these topics focuses mainly on the introductory material. While there is some discussion of the various ethical arguments, it is less comprehensive or detailed compared to other chapters. However, several primary resources are listed to supplement the discussion in the textbook. (shrink)

Imagine a world where everyone is healthy, intelligent, long living and happy. Intuitively this seems wonderful albeit unrealistic. However, recent scienti c breakthroughs in genetic engineering, namely CRISPR/Cas bring the question into public discourse, how the genetic enhancement of humans should be evaluated morally. In 2001, when preimplantation genetic diagnosis (PGD) and in vitro fertilisation (IVF), enabled parents to select between multiple embryos, Julian Savulescu introduced the principle of procreative bene cence (PPB), stating that parents have the obligations to choose (...) the child that is expected to have the best life. In this paper I argue that accepting the PPB and the consequentialist principle (CP) that two acts with the same consequences are morally on par, commits one to accepting the parental obligation of genetically enhancing one's children.

A new reprogenetic technology, mitochondrial replacement, is making its appearance and, unsurprisingly given its promise to wash off our earthly stains --or at least the scourges of sexual reproduction--, John Harris finds only reasons to celebrate this new scientific feat.1 In fact, he finds mitochondrial replacement techniques (MRTs) so “unreservedly welcome” that he believes those who reject them suffer from “a large degree of desperation and not a little callousness.”2 Believing myself to be neither desperate nor callous, but finding myself (...) also no closer at all – not even after reading his article—to following Harris in welcoming these technologies wholeheartedly, it seems appropriate to respond.

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.

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)
