Biomedical technologies can increasingly be used not only to combat disease, but also to augment the capacities or traits of normal, healthy people – a practice commonly referred to as biomedical enhancement. Perhaps the best‐established examples of biomedical enhancement are cosmetic surgery and doping in sports. But most recent scientific attention and ethical debate focuses on extending lifespan, lifting mood, and augmenting cognitive capacities.

Some philosophers and theologians have argued against the idea of Human Enhancement, saying that human beings should not play God. A closer look, however, might reveal that the question of who is playing Whom is far from being so clear-cut. This chapter will address the idea of human enhancement from the standpoint of theistic theology, arguing that human enhancement and theistic theology may not be so very incompatible, after all.

After describing the disorder of psychopathy, I examine the theories and the evidence concerning the psychopaths’ deficient moral capacities. I first examine whether or not psychopaths can pass tests of moral knowledge. Most of the evidence suggests that they can. If there is a lack of moral understanding, then it has to be due to an incapacity that affects not their declarative knowledge of moral norms, but their deeper understanding of them. I then examine two suggestions: it is their deficient (...) practical reason or their stunted emotions that are at fault. The evidence supports both explanations. I conclude with an overview of the debate concerning whether they are morally or legally responsible for their actions. (shrink)

Using medical advances to enhance human athletic, aesthetic, and cognitive performance, rather than to treat disease, has been controversial. Little is known about physicians? experiences, views, and attitudes in this regard. We surveyed a national sample of physicians to determine how often they prescribe enhancements, their views on using medicine for enhancement, and whether they would be willing to prescribe a series of potential interventions that might be considered enhancements. We find that many physicians occasionally prescribe enhancements, but doctors hold (...) nuanced and ambiguous views of these issues. Most express concerns about the potential effects of enhancements on social equity, yet many also believe specific enhancements that are safe and effective should be available but not covered by insurance. These apparently contradictory views might reflect inherent tensions between the values of equity and liberty, which could make crafting coherent social policies on medical enhancements challenging.

Although the philosophical literature on the ethics of human prenatal genetic alteration purports to inform us about how to act, it rarely explicitly recognizes the perspective of those who will be making the PGA decision in practice. Here I approach the ethics of PGA from a distinctly virtue-based perspective, taking seriously what it means to be a good parent making this decision for one’s child. From this perspective, I generate a sound verdict on the moral standing of human PGA : (...) given the current state of the art, good parents have compelling reason not to consent to PGA for their child, especially as part of the first wave of PGA research participants and especially for non-medically oriented purposes. This is because doing otherwise is inconsistent with a plausible and defensible understanding of virtuous parenting and parental virtues, founded on a genuine concern for promoting the overall flourishing of the eventual child. In essence, given the current and foreseeable state of the art, parents who allow prenatal genetic alteration of their children are less-than-virtuous parents to those children, even in cases where they have a right to do so and even if PGA turns out to be beneficial to the eventual child.

In her short story “Stable Strategies for Middle Management,” Eileen Gunn imagines a future in which Margaret, an office worker, seeks radical genetic enhancements intended to help her secure the middle-management job she wants. One source of the story’s tension and dark humor is dramatic irony: readers can see that the enhancements Margaret buys stand little chance of making her life go better for her; enhancing is, for Margaret, probably a prudential mistake. This paper argues that our positions in the (...) real world are sufficiently similar to Margaret’s position in Gunn’s fictional world that we should take this story seriously as grounding an argument from analogy for the conclusion that radical genetic enhancements are, for us, probably a prudential mistake. The paper then defends this method. When the question at hand is one of speculative ethics, there is no method better fit to the purpose than argument from analogy to speculative fiction. (shrink)

Abstract:An integrated and principled neuroethics offers ethical guidelines able to transcend conventional and medical reliance on normality standards. Elsewhere we have proposed four principles for wise guidance on human transformations. Principles like these are already urgently needed, as bio- and cyberenhancements are rapidly emerging. Context matters. Neither “treatments” nor “enhancements” are objectively identifiable apart from performance expectations, social contexts, and civic orders. Lessons learned from disability studies about enablement and inclusion suggest a fresh way to categorize modifications to the body (...) and its performance. The term “enhancement” should be broken apart to permit recognition of enablements and augmentations, and kinds of radical augmentation for specialized performance. Augmentations affecting the self, self-worth, and self-identity of persons require heightened ethical scrutiny. Reversibility becomes the core problem, not the easy answer, as augmented persons may not cooperate with either decommissioning or displacement into unaccommodating societies. We conclude by indicating how our four principles of self-creativity, nonobsolescence, empowerment, and citizenship establish a neuroethics beyond normal that is better prepared for a future in which humans and their societies are going so far beyond normal.

Abstract:Research into the development of stem cell-derived (SCD) gametes in humans, otherwise known asin vitrogametogenesis (IVG), is largely motivated by reproductive aims. Especially, the goal of establishing genetic parenthood by means of SCD-gametes is considered an important aim. However, like other applications in the field of assisted reproduction, this technology evokes worries about the possibility of creating so-called ‘designer babies.’ In this paper, we investigate various ways in which SCD-gametes could be used to create such preference-matched offspring, and what this (...) would mean for the acceptability of IVG, if it is premised that it is morally problematic to ‘design’ offspring. We argue that IVG might facilitate the creation of preference-matched offspring, but conclude that this should not undermine the moral acceptability of IVG altogether—even if one concedes the premise that creating ‘designer babies’ is morally problematic. In the light of this, we also point at a possible inconsistency for a position that condemns the creation of ‘designer offspring,’ while accepting the various endeavors to have genetically related offspring.

The ethics of human enhancement has been a hotly debated topic in the last 15 years. In this debate, some advocate examining science fiction stories to elucidate the ethical issues regarding the current phenomenon of human enhancement. Stories from science fiction seem well suited to analyze biomedical advances, providing some possible case studies. Of particular interest is the work of screenwriter Andrew Niccol (Gattaca, S1m0ne, In Time, and Good Kill), which often focuses on ethical questions raised by the use of (...) new technologies. Examining the movie In Time (2011), the aim of this paper is to show how science fiction can contribute to the ethical debate of human enhancement. In Time provides an interesting case study to explore what could be some of the consequences of radical life-extension technologies. In this paper, we will show how arguments regarding radical life-extension portrayed in this particular movie differ from what is found in the scientific literature. We will see how In Time gives flesh to arguments defending or rejecting radical life-extension. It articulates feelings of unease, alienation and boredom associated with this possibility. Finally, this article will conclude that science fiction movies in general, and In Time in particular, are a valuable resource for a broad and comprehensive debate about our coming future. (shrink)

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.

What is the place of vulnerability in our lives? The current debate about the ethics of enhancement technologies provides a context in which to think about this question. In my view, the current debate is likely to be fruitless, largely because we bring the wrong ethical resources to bear on its questions. In this article, I recall an important, but currently neglected, role that moral concepts play in our thinking, a role they should especially play in relation to the introduction (...) of new technologies. I call this the ‘contemplative role of moral concepts’. I then contrast two approaches to the contemplative role of moral concepts which are found in the current literature, and show why it is important to keep in mind both of these approaches when thinking about human vulnerability.

In an intriguing essay, G. A. Cohen has defended a conservative bias in favour of existing value. In this paper, we consider whether Cohen’s conservatism raises a new challenge to the use of human enhancement technologies. We develop some of Cohen’s suggestive remarks into a new line of argument against human enhancement that, we believe, is in several ways superior to existing objections. However, we shall argue that on closer inspection, Cohen’s conservatism fails to offer grounds for a strong sweeping (...) objection to enhancement, and may even offer positive support for forms of enhancement that preserve valuable features of human beings. Nevertheless, we concede that Cohen’s arguments may suggest some plausible and important constraints on the modality of legitimate and desirable enhancements. (shrink)

Mosquito-borne diseases represent a significant global disease burden, and recent outbreaks of such diseases have led to calls to reduce mosquito populations. Furthermore, advances in ‘gene-drive’ technology have raised the prospect of eradicating certain species of mosquito via genetic modification. This technology has attracted a great deal of media attention, and the idea of using gene-drive technology to eradicate mosquitoes has been met with criticism in the public domain. In this paper, I shall dispel two moral objections that have been (...) raised in the public domain against the use of gene-drive technologies to eradicate mosquitoes. The first objection invokes the concept of the ‘sanctity of life’ in order to claim that we should not drive an animal to extinction. In response, I follow Peter Singer in raising doubts about general appeals to the sanctity of life, and argue that neither individual mosquitoes nor mosquitoes species considered holistically are appropriately described as bearing a significant degree of moral status. The second objection claims that seeking to eradicate mosquitoes amounts to displaying unacceptable degrees of hubris. Although I argue that this objection also fails, I conclude by claiming that it raises the important point that we need to acquire more empirical data about, inter alia, the likely effects of mosquito eradication on the ecosystem, and the likelihood of gene-drive technology successfully eradicating the intended mosquito species, in order to adequately inform our moral analysis of gene-drive technologies in this context.

This paper shows how critical realism can be used to integrate empirical data and philosophical analysis within ‘empirical bioethics’. The term empirical bioethics, whilst appearing oxymoronic, simply refers to an interdisciplinary approach to the resolution of practical ethical issues within the biological and life sciences, integrating social scientific, empirical data with philosophical analysis. It seeks to achieve a balanced form of ethical deliberation that is both logically rigorous and sensitive to context, to generate normative conclusions that are practically applicable to (...) the problem, challenge, or dilemma. Since it incorporates both philosophical and social scientific components, empirical bioethics is a field that is consistent with the use of critical realism as a research methodology. The integration of philosophical and social scientific approaches to ethics has been beset with difficulties, not least because of the irreducibly normative, rather than descriptive, nature of ethical analysis and the contested relation between fact and value. However, given that facts about states of affairs inform potential courses of action and their consequences, there is a need to overcome these difficulties and successfully integrate data with theory. Previous approaches have been formulated to overcome obstacles in combining philosophical and social scientific perspectives in bioethical analysis; however each has shortcomings. As a mature interdisciplinary approach critical realism is well suited to empirical bioethics, although it has hitherto not been widely used. Here I show how it can be applied to this kind of research and explain how it represents an improvement on previous approaches. (shrink)

Several authors, including Michael Sandel, distinguish between two different attitudes toward nature: mastery and giftedness. Giftedness is the superior attitude, Sandel argues, because it better accords with the values of humility, responsibility, and solidarity. And giftedness, in combination with these values, provides a rational basis for opposing the employment of genetic enhancement. Against this, I argue that talents and genetic endowment are more plausibly viewed as undeserved, that not everything undeserved is a gift, and that even if talents and endowment (...) were gifts, this would not support a prohibition against pursuing genetic enhancement.

Until recently, the problem of traumatic brain injury in sports and the problem of performance enhancement via hormone replacement have not been seen as related issues. However, recent evidence suggests that these two problems may actually interact in complex and previously underappreciated ways. A body of recent research has shown that traumatic brain injuries, at all ranges of severity, have a negative effect upon pituitary function, which results in diminished levels of several endogenous hormones, such as growth hormone and gonadotropin. (...) This is a cause for concern for many popular sports that have high rates of concussion, a mild form of TBI. Emerging research suggests that hormone replacement therapy is an effective treatment for TBI-related hormone deficiency. However, many athletic organizations ban or severely limit the use of hormone replacing substances because many athletes seek to use them solely for the purposes of performance enhancement. Nevertheless, in the light of the research linking traumatic brain injury to hypopituitarism, this paper argues that athletic organizations’ policies and attitudes towards hormone replacement therapy should change. We defend two claims. First, because of the connection between TBI and pituitary function, it is likely many more athletes than previously acknowledged suffer from hormone deficiency and thus could benefit from hormone replacement therapy. Second, athletes’ hormone levels should be tested more rigorously and frequently with an emphasis on monitoring TBI and TBI-related issues, rather than simply monitoring policy violations. (shrink)

Advances in reproductive genetic engineering have the potential to transform human lives. Not only do they promise to allow us to select children free of diseases, they can also enable us to select children with desirable traits. In this paper, I consider two clusters of arguments for the moral permissibility of reproductive genetic engineering, what I call the Perfectionist View and the Libertarian View; and two clusters of arguments against reproductive genetic engineering, what I call the Human Nature View and (...) the Motivation View. I argue that an adequate theory of the ethics of reproductive genetic engineering should take into account insights gained from these views. (shrink)

Frances Kamm distinguishes between changes or enhancements that are made before a child exists (ex ante changes) and those that are made once a child exists (ex post changes), and she argues that ex ante changes do not show disrespect or, as Michael Sandel would put it, lack of love, for a person, since the person does not yet exist. In this paper, I argue that it is important to distinguish between ex ante enhancements that are morally neutral and those (...) that are morally dubious, and that the latter ones are morally objectionable even if the persons do not yet exist.

This focus issue considers the normative implications of the recent emergence in genome editing technology known as CRISPR (clustered regularly interspaced short palindromic repeats) or CRISPR‐associated protein 9. Originally discovered in the adaptive immune systems of bacteria and archaea, CRISPR enables researchers to make efficient and site‐specific modifications to the genomes of cells and organisms. More accessible, precise, and economic than previous gene editing technologies, CRISPR holds the promise of not only transforming the fields of genetics, agriculture, and human medicine, (...) but also heralding a new era of democratized biotechnology. However, the speed with which developments in the field have progressed threatens to overwhelm our normative sensibilities about the long‐term practical and ethical implications. The contributors to this focus issue attempt to think through some of the more salient moral and practical consequences of CRISPR in the context of religious ethics, particularly as they relate to themes of autonomy, human flourishing, social justice, and the ethics of enhancement.

In his book, The Case Against Perfection, Michael J. Sandel has offered several arguments against biomedical human enhancements. However, his views have been forcefully criticized by Frances M. Kamm. This paper argues that while Kamm is correct in arguing that Sandel fails to establish the moral impermissibility of enhancements, he, nevertheless, offers resources for articulating our unease with enhancements. In particular, this paper argues that being willing to enhance oneself in any way is incompatible with having an identity as a (...) person. (shrink)

A pertinent concern in the human enhancement debate is that human enhancement technologies (HET) are intrinsically bad and, hence, morally impermissible. This article evaluates the related claims about the intrinsic badness of HET by looking into philosophical theories of intrinsic value. It investigates how well-established conceptions of intrinsic value map onto typical bioconservative arguments about HET's intrinsic badness. Three predominant variants of these arguments are explored and found wanting: (i) HET are intrinsically bad owing to their unnaturalness; (ii) the pursuit (...) of HET reveals intrinsically bad character (“the desire for mastery”); and (iii) HET will necessarily undermine intrinsically valuable things (e.g., human dignity). My analysis shows that the debate on intrinsic value places serious constraints on claims about the intrinsic badness of HET. More specifically, the analysis shows that bioconservative arguments are, for the most part, inconsistent, misconceived, and overly speculative. Enhancement interventions cannot be bearers of intrinsic value on any of its plausible understandings, and, even if we could grant such a possibility, there are no compelling reasons to presume that the intrinsic value of HET would be necessarily negative. As a result, claims regarding their moral impermissibility are unwarranted. (shrink)

New technologies facilitate the enhancement of a wide range of human dispositions, capacities, or abilities. While it is argued that we need to set limits to human enhancement, it is unclear where we should find resources to set such limits. Traditional routes for setting limits, such as referring to nature, the therapy-enhancement distinction, and the health-disease distinction, turn out to have some shortcomings. However, upon closer scrutiny the concept of enhancement is based on vague conceptions of what is to be (...) enhanced. Explaining why it is better to become older, stronger, and more intelligent presupposes a clear conception of goodness, which is seldom provided. In particular, the qualitative better is frequently confused with the quantitative more. We may therefore not need “external” measures for setting its limits – they are available in the concept of enhancement itself. While there may be shortcomings in traditional sources of limit setting to human enhancement, such as nature, therapy, and disease, such approaches may not be necessary. The specification-of-betterment problem inherent in the conception of human enhancement itself provides means to restrict its unwarranted proliferation. We only need to demand clear, sustainable, obtainable goals for enhancement that are based on evidence, and not on lofty speculations, hypes, analogies, or weak associations. Human enhancements that specify what will become better, and provide adequate evidence, are good and should be pursued. Others should not be accepted. (shrink)

This article explores the current parenting culture, particularly the promotion of competitive and excessive parenting, as an important background issue against which the debates around pre-natal testing take place. It offers an alternative vision of parenting, relying on care ethics, which sees parenting as a relationship, rather than a job. A relationship that should change a parent’s understanding of what is valuable in life. Parenting should not be about moulding the ‘perfect child’ but being open to being profoundly changed. The (...) parent–child with a disability relationship offers particular opportunities to find new meanings and values in life. This analysis is offered as another dimension to the debates over pre-natal testing. It is not intended as an argument against such testing, but rather raises concerns about some of the broader attitudes around it. (shrink)

Analytic philosophers tend to agree that intentional parental genetic shaping and intentional parental environmental shaping for the same feature are, normatively, on a par. I challenge this view by advancing a novel argument, grounded in the value of fair relationships between parents and children: Parental genetic shaping is morally objectionable because it unjustifiably exacerbates the asymmetry between parent and child with respect to the voluntariness of their entrance into the parent–child relationship. Parental genetic shaping is, for this reason, different from (...) and more objectionable than parental environmental shaping. I introduce a distinction between procreative decisions one makes qua mere procreator—that is, without the intention to rear the resulting child—and procreative decisions one makes qua procreator-and-future childrearer. Genetic shaping is objectionable when undertaken in the latter capacity: Both selection and enhancement are objectionable because they introduce an unnecessary and avoidable inequality in the parent–child relationship; in the case of enhancement, this also results in harm to the future child.

I argue that young patients should be able to access neuroenhancing drugs without a diagnosis of ADHD. The current framework of consent for pediatric patients can be adapted to accommodate neuroenhancement. After a brief overview of pediatric neuroenhancement, I develop three arguments in favor of greater acceptance of neuroenhancement for young patients. First, ADHD is not relevantly different from other disadvantages that could be treated with stimulant medication. Second, establishing a legitimate framework for pediatric neuroenhancement would mitigate the bad effects (...) of diversion and improve research on neuroenhancement and ADHD. Third, some pediatric patients have rights to access neuroenhancements. I then consider several objections to pediatric neuroenhancement. I address concerns about addiction, advertising, authentic development, the parent–child relationship and equal opportunity and conclude that these concerns may inform a framework for prescribing neuroenhancement but they do not justify limits on prescribing.

By using preimplantation haplotype diagnosis, prospective parents are able to select embryos to implant through in vitro fertilization. If we knew that the naturally-occurring (but theoretical) MoralKinder (MK+) haplotype would predispose individuals to a higher level of morality than average, is it permissible or obligatory to select for the MK+ haplotype? I.e., is it moral to select for morality? This paper explores the various potential issues that could arise from genetic moral enhancement.

Several philosophers have argued that human enhancements should be considered a potential solution to climate change. In this paper, I consider one such argument offered by S. Matthew Liao, Anders Sandberg, and Rebecca Roache. I argue that, while their argument is plausible, we have an even stronger reason to consider enhancements a potential solution. In particular, enhancements could align our interests with the promotion of a proper response to climate change: if enhancements were in our interest to adopt and also (...) reduced the pernicious effects of climate change, then it would, indirectly, become in our interest to reduce those effects.

Many have argued that human enhancement, in particular bioenhancement via genetic engineering, brain-interventions or preimplantation embryo selection, is problematic even if it can be safely implemented. Various arguments have been put forward focusing on issues such as the undermining of autonomy, uneven distribution and unfairness, and the alteration of one’s identity, amongst others. Nevertheless, few, if any, of these thinkers oppose vaccines. -/- In what follows, I argue for the permissibility of a limited set of cognitive enhancements – in particular, (...) the enhancement of evaluative judgment and self-control – by analogy with the permissibility of vaccines. As a result, it follows that if one accepts the permissibility of vaccines one will also, other things being equal, be committed to the permissibility of these enhancements. I then consider and respond to a number of possible objections in order to defend and clarify my position. (shrink)

This paper assesses how views of disability and enhancement can combine. It is hard to maintain that disabilities and enhancements are both undesirable. Disability-positive views can combine with support for or opposition to enhancement, but not with the view that enhanced traits reliably increase well-being. It is consistent to hold that disability is bad and enhancement good; the plausibility of this combination depends on whether it is better to have more options and fewer limitations. Understanding these combined positions makes it (...) easier to check for consistency by evaluating positions on disability and enhancement against each other. (shrink)

In a sex selective abortion, a woman aborts a fetus simply on account of the fetus’ sex. Her motivation or underlying reason for doing so may very well be sexist. She could be disposed to thinking that a female child is inferior to a male one. In a hate crime, an individual commits a crime on account of a victim’s sex, race, sexual orientation or the like. The individual may be sexist or racist in picking his victim. He or she (...) could be disposed to thinking that one race or sex is inferior to another. I argue that while a prohibition on sex selective abortions is anomalous in a liberal, criminal legal framework, hate crime legislation may not be. The former but not the latter constitutes a thought crime. I define a thought crime as one where an agent’s motivation is not just relevant but sufficient to take an act from the domain of the non-punishable to the domain of the punishable. Ignoring a woman’s sexist motivation in procuring an abortion suddenly renders her act of abortion legal. On the other hand, discounting an agent’s bias in committing a hate motivated assault or murder does not transform the act from a punishable one to a non-punishable one. Assaulting or murdering is already a crime. (shrink)
