Ethical debate surrounding human enhancement, especially by biotechnological means, has burgeoned since the turn of the century. Issues discussed include whether specific types of enhancement are permissible or even obligatory, whether they are likely to produce a net good for individuals and for society, and whether there is something intrinsically wrong in playing God with human nature. We characterize the main camps on the issue, identifying three main positions: permissive, restrictive and conservative positions. We present the major sub-debates and lines (...) of argument from each camp. The review also gives a flavor of the general approach of key writers in the literature such as Julian Savulescu, Nick Bostrom, Michael Sandel, and Leon Kass. (shrink)

Celem artykułu jest krytyka kilku popularnych argumentów przeciwko wykorzystywaniu współczesnych osiągnięć biomedycznych do poprawiania ludzkiej kondycji fizycznej lub umysłowej. Na przykładzie prac Habermasa, Sandela, Fukuyamy omówię trzy argumenty tego typu odwołujące się do: 1) autonomii; 2) życia jako daru; 3) naturalnej równowagi. Na koniec pokażę, że sprzeciw względem niektórych propozycji biomedycznego polepszenia kondycji ludzkiej może być wynikiem swoistego błędu poznawczego, który psychologowie określają jako efekt status quo.

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.

Several authors have suggested that we cannot fully grapple with the ethics of human enhancement unless we address neglected questions about our place in the world, questions that verge on theology but can be pursued independently of religion. A prominent example is Michael Sandel, who argues that the deepest objection to enhancement is that it expresses a Promethean drive to mastery which deprives us of openness to the unbidden and leaves us with nothing to affirm outside our own wills. Sandel's (...) argument against enhancement has been criticized, but his claims about mastery and the unbidden, and their relation to religion, have not yet received sufficient attention. I argue that Sandel misunderstands the notions of mastery and the unbidden and their significance. Once these notions are properly understood, they have surprising implications. It turns out that the value of openness to the unbidden is not just independent of theism, as Sandel claims, but is in fact not even fully compatible with it. But in any case that value cannot support Sandel's objection to enhancement. This is because it is not enhancement but certain forms of opposition to enhancement that are most likely to express a pernicious drive to mastery. (shrink)

Michael Sandel's opposition to the project of human enhancement is based on an argument that centres on the notion of giftedness. Sandel claims that by trying to ?make better people? we fall prey to, and encourage, an attitude of mastery and thus lose, or diminish, our appreciation of the giftedness of life. Sandel's position and the underlying argument have been much criticised. In this paper I will try to make sense of Sandel's reasoning and give an account of giftedness that (...) defends its relevance for the ethical assessment of the human enhancement project. In order to do so, I will also look at virtue-related notions, such as gratitude and humility, and distinguish the gifted from the merely given. The failure to acknowledge this distinction gives rise to one of the most common objections to Sandel's argument. Other objections will be shown to rest on similar misunderstandings. (shrink)

Cognitive enhancement takes many and diverse forms. Various methods of cognitive enhancement have implications for the near future. At the same time, these technologies raise a range of ethical issues. For example, they interact with notions of authenticity, the good life, and the role of medicine in our lives. Present and anticipated methods for cognitive enhancement also create challenges for public policy and regulation.

Suppose a woman can carry to term only one of two viable embryos. One has the genetic potential to become a normal child. The other has a gene that gives it the potential for both the artistic genius and the severe manic-depression of the painter Vincent Van Gogh. I think it would be permissible to select either embryo. But I also believe that it would be impermissible to intervene to turn an embryo that has the potential to be normal into (...) a potential Van Gogh, and vice versa. The paper aims to resolve the tension between these beliefs. (shrink)

No artigo, abordo a ideia de melhoramento humano (MH), visando a contestar três frustrantes tendências dos seus críticos, a saber, as ideias de: (1) que a natureza humana será artificializada, sugerindo que estaremos diante de algo novo e incomparavelmente perigoso, bem como que ainda seja possível preservar uma separação radical entre natureza e técnica; (2) que é possível abordar e criticar o MH a partir de uma singularidade semântica; e, diretamente relacionada à anterior, (3) que há univocidade entre os defensores (...) do MH acerca de como os indivíduos devem lidar com os meios biotecnocientíficos disponibilizados, a saber, como uma ingênua e acrítica obrigação de melhorar. In this paper, I discuss the idea of human enhancement (HE). My goal is to refute three frustrating trends in the HE criticism, namely the ideas that: (1) human nature will become artificial, suggesting that we will be facing something new and uniquely dangerous, and that it is still possible to preserve a radical separation between nature and technique; (2) it is possible to address and criticize HE from a semantic uniqueness, which is directly related to the previous item; and (3) there is an univocity among the HE's defenders on how individuals should handle the available bio-techno-scientific tools made available, namely, as a naive and uncritical obligation to become enhanced.

As we learn more about the human brain, novel biotechnological means to modulate human behaviour and emotional dispositions become possible. These technologies could be used to enhance our morality. Moral bioenhancement, an instance of human enhancement, alters a person’s dispositions, emotions or behaviour in order to make that person more moral. I will argue that moral bioenhancement could be carried out in three different ways. The first strategy, well known from science fiction, is behavioural enhancement. The second strategy, favoured by (...) prominent defenders of moral bioenhancement, is emotional enhancement. The third strategy is the enhancement of moral dispositions, such as empathy and inequity aversion. I will argue that we ought to implement a combination of the second and third strategies. Furthermore, I will argue that the usual arguments against other instances of human enhancement do not apply to moral bioenhancement, or apply only to the first strategy, behavioural enhancement.

Emerging technologies are increasingly used in an attempt to “enhance the human body and/or mind” beyond the contemporary standards that characterize human beings. Yet, such standards are deeply controversial and it is not an easy task to determine whether the application of a given technology to an individual and its outcome can be defined as a human enhancement or not. Despite much debate on its potential or actual ethical and social impacts, human enhancement is not subject to any consensual definition. (...) This paper proposes a timely and much needed examination of the various definitions found in the literature. We classify these definitions into four main categories: the implicit approach, the therapy-enhancement distinction, the improvement of general human capacities and the increase of well-being. After commenting on these different approaches and their limitations, we propose a definition of human enhancement that focuses on individual perceptions. While acknowledging that a definition that mainly depends on personal and subjective individual perceptions raises many challenges, we suggest that a comprehensive approach to define human enhancement could constitute a useful premise to appropriately address the complexity of the ethical and social issues it generates.

With the recent advancements in scientific comprehension of genetics and the decipherment of complex techniques for editing human genomes, liberal eugenics—eugenic ideal premised on the liberal values of autonomy and pluralism that leaves reproductive choices to parents rather than anachronistic statist authoritarian interventions—has inevitably become a polarising conundrum in contemporary liberal societies as to its utility and destructiveness. Focusing on one species of liberal eugenics—namely, genome editing interventions—I contend that liberal eugenics could be harmful—harm herein construed as that which undermines (...) the salient liberal values of equality, autonomy, and pluralism—since it is itself antithetical to the bases of the liberal society. This contention is based upon three premises: first, that individuals are rather seldom rational decision-makers such that leaving all reproductive choices to the whims of individual parents would be immensely counterproductive to future offspring’s right to open future; second, that liberal eugenics—much like its authoritarian antecedent—could intersect with myriad identities, including race, class, sex, disability, and sexual orientation in ways that might exacerbate social divisions, marginalise different groups, and engender homogeneity; and third, that it undermines individual autonomy of the future person as a member of the liberal community, particularly if their capacities and abilities are tailored to fit parents’ specific life projects and putatively reasonable conceptions of the good. The underscored potential malaises of liberal eugenics should, I argue, be discursively negotiated between parents and the state via the development of robust general laws that regulate heritable genome editing interventions to ensure that the welfare of the future persons is prioritised and that the liberal commitment to autonomy is immune to antiliberal perversions.

Two clusters of essays in this issue of The Journal of Medicine and Philosophy provide a critical gaze through which to explore central moral, phenomenological, ontological, and political concerns regarding human moral agency and personal responsibility. The first cluster challenges common assumptions in bioethics regarding the voluntariness of human actions. The second set turns the debate towards morally responsible choice within the requirements of distributive justice. The force of their collective analysis leaves us with a well-founded basis critically to approach (...) any account of bioethics or health policy that is insufficiently attentive to the central challenges of human freedom and responsible free choice.

Health behaviors such as tobacco use contribute significantly to poor health. It is widely recognized that efforts to prevent poor health outcomes should begin in early childhood. Biomedical enhancements, such as a nicotine vaccine, are now emerging and have potential to be used for primary prevention of common diseases. In anticipation of such enhancements, it is important that we begin to consider the ethical and policy appropriateness of their use with children. The main ethical concerns raised by enhancing children relate (...) to their impact on children’s well-being and autonomy. These concerns are significant, however they do not appear to apply in the case of the nicotine vaccine; indeed the vaccine could even further these goals for children. Nevertheless, concerns about broadly applying this enhancement may be more challenging. The vaccine may be less cost-effective than alternative public efforts to prevent tobacco use, utilizing it could distract from addressing the foundational causes of smoking and it might not be publically acceptable. Empirical research about these concerns is needed to ascertain their likelihood and impact as well as how they could be minimized. This research could help determine whether behavior-related enhancements hold promise for improving children’s health. (shrink)

What role should sentient animals play in the current debate on enhancement? The question covers several different philosophical fronts that demand urgent global ethical analysis. This touches issues that go from prohibition, permissivity or obligation that should characterize the new biotechnologies oriented to the enhancement of individuals, to the debate surrounding the moral rights of animals. Furthermore, the difficulty arises not only from the controversial moral categories involved, but also from the very extent of the objective proposed. However, this also (...) gives rise to the pertinence of the above-mentioned question posed at the outset: on the one hand, the need for consistency in an eminently biased debate, and on the other the need to justify the proposal in which all sentient individuals are legitimate protagonists without this necessarily leading to implausible scenarios.

In this chapter, I propose the mechanism of cognitive enhancement based on studies of cognitive-enhancing drugs and behavioral training. I argue that there are mechanistic differences between cognitive-enhancing drugs and behavioral training due to their different enhancing effects. I also suggest possible mechanisms for cognitive-enhancing drugs and behavioral training and for the synergistic effects of their simultaneous application.

Essay I explores brain machine interface technologies. These make direct communication between the brain and a machine possible by means of electrical stimuli. This essay reviews the existing and emerging technologies in this field and offers an inquiry into the ethical problems that are likely to emerge. Essay II, co-written with professor Sven-Ove Hansson, presents a novel procedure to engage the public in deliberations on the potential impacts of technology. This procedure, convergence seminar, is a form of scenario-based discussion that (...) is founded on the idea of hypothetical retrospection. The theoretical background and the results of the five seminars are presented. Essay III discusses moral bioenhancement, an instance of human enhancement that alters a person’s dispositions, emotions or behavior. Moral bioenhancement could be carried out in three different ways. The first strategy is behavioral enhancement. The second strategy, favored by prominent defenders of moral enhancement, is emotional enhancement. The third strategy is the enhancement of moral dispositions, such as empathy and inequity aversion. I argue that we ought to implement a combination of the second and third strategies. Essay IV considers the possibility and potential desirability of sensory enhancement. It is proposed that existing sensory modalities in vertebrate animals are proof of concept of what is biologically possible to create in humans. Three considerations on the normative aspects of sensory enhancement are also presented in this essay. Essay V rejects disease prioritarianism, the idea that the healthcare system ought to prioritize the treatment of diseases. Instead, an approach that focuses on what medicine can accomplish is proposed. Essay VI argues that from the idea that species have an intrinsic value and that humanity has a collective responsibility to protect animal species from extinction, the conclusion that we ought to recreate species follows. Essay VII argues that unknown existential risks have not been properly addressed. It proposes a heuristic for doing so, and a concrete strategy. This strategy consists in building refuges that could withstand a large number of catastrophic events. (shrink)

Deberíamos usar las nuevas técnicas biomédicas para mejorar a los individuos? Si sabemos que la naturaleza humana contiene también características que podemos considerar no deseables entonces parece que no habría nada en sí mismo erróneo a la hora de alterarla. Algunos autores interesados en este tema hacen referencia a los daños que ello podría ocasionar a otros. Pero entonces, ¿la mejora moral podría funcionar como un contraejemplo a la idea de que la mejora biomédica es siempre moralmente impermisible? Puede que (...) lejos de estar ante algo meramente permisible, la mejora de nuestro carácter moral sea algo a lo que debamos aspirar. ¿Sería entonces obligatorio seleccionar los embriones con un nivel más alto de moralidad?

A faulty understanding of the relationship between morality and politics encumbers many contemporary debates on human enhancement. As a result, some ethical reflections on enhancement undervalue its social dimensions, while some social approaches to the topic lack normative import. In this essay, I use my own conception of the relationship between ethics and politics, which I call “political minimalism,” in order to support and strengthen the existing social perspectives on human-enhancement technologies.

Probablemente la mayor responsabilidad actual de la ética aplicada es hacerse cargo de las grandes dificultades teórico-prácticas generadas con el incipiente desarrollo de las nuevas tecnologías de biomejora. Dificultades más allá de las preferencias individuales, viéndose involucradas cuestiones en torno a nuestra comprensión de la justicia distributiva. La identificación de dos hechos importantes nos da la clave para orientar el debate. Por un lado, las situaciones de partida tan arbitrarias que proporciona la lotería natual con relación a las oportunidades de (...) bienestar individual. Por otro, la posibilidad de realizar una mejora cognitiva, de aquellos más desafortunados en su configuración genética, que incidirá en la amplificación de tales oportunidades. (shrink)
