Both, bioconservatives and bioliberals, should seek a discussion about ideas of human perfection, making explicit their underlying assumptions about what makes for a good human life. This is relevant, because these basic, and often implicit ideas, inform and influence judgements and choices about human enhancement interventions. Both neglect, and polemical but inconsistent use of the complex ideas of perfection are leading to confusion within the ethical debate about human enhancement interventions, that can be avoided by tackling the notion of perfection (...) directly. In the recent debates, bioconservatives have prominently argued against the ‘pursuit of perfection’ by biotechnological means. In the first part of this paper, we show that—paradoxically—bioconservatives themselves explicitly embrace specific conceptions of human perfection and perfectionist assumptions about the good human life in order to argue against the use of enhancement technologies. Yet, we argue that the bioconservative position contains an untenable ambiguity between criticising and endorsing ideas of human perfection. Hence, they stand in need of clarifying their stance on human perfection. In the second part of the paper, we ask whether bioliberals in fact (implicitly) advocate a particular conception of perfection, or whether they are right in holding that they do not, and that discussing perfection is obsolete anyway. We show that bioliberals also rely on a specific idea of human perfection, based on the idea of autonomy. Hence, their denial of the relevance of perfection in the debate is unconvincing and has to be revised. (shrink)

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.

Recent biotechnological advances pose topical challenges to Christian ethics. One such development is the attempt to try and enhance human beings and what it means to be human, also through radical life extension. In this contribution I am especially interested in limited human lifespan and attempts to radically prolong it. Although there are a number of ethical issues raised by critics, one of the most profound ethical and theological issues raised by these efforts is the question of equity and justice. (...) This artice looks at questions such as whether this biotechnology could exacerbate existing social divisions. Who will be experimented on in the development of this technology, as well as who will have access to it and be able to afford it, should it become commercially available? Being created in God’s image is a relational concept, referring not only to humanity’s relationship with God, but also with each other. Disrupting these relationships through the possible enlarging socioeconomic divisions between people through the utilisation of enhancement technology is a serious bioethical and theological question.

Should or shouldn’t Christians endorse the transhumanist agenda of changing human nature in ways fitting to one’s needs? To answer this question, we first have to be clear on what precisely the thesis of transhumanism entails that we are going to evaluate. Once this point is clarified, I argue that Christians can in principle fully endorse the transhumanist agenda because there is nothing in Christian faith that is in contradiction to it. In fact, given certain plausible moral assumptions, Christians should (...) endorse a moderate enhancement of human nature. I end with a brief case study that analyses the theological implications of the idea of immortal Christian cyborgs. I argue that the existence of Christian cyborgs who know no natural death has no impact on the Christian hope of immortality in the presence of God. (shrink)

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.

Transformative technologies can radically alter human lives making us stronger, faster, more resistant to disease and so on. These include enhancement technologies as well as cloning and stem cell research. Such technologies are often approved of by many liberals who see them as offering us opportunities to lead better lives, but are often disapproved of by conservatives who worry about the many consequences of allowing these to be used. In this paper, we consider how a democratic government with mainly liberal (...) values that is governing a population divided between liberals and conservatives can introduce new transformative technologies and try to achieve consensus about the introduction of such technologies. To do so, we draw on recent work in moral psychology which enables us to better understand the intuitive and emotional responses that underpin conservative objections to such new technologies. We then show how a government may introduce incremental changes in our social practices that have the long-term effect of weakening conservative objections to transformative technologies and better enabling governments to achieve consensus about these.

No agreement exists among ethical theories on what cancount as a right moral motivation. This hampers us from knowingwhether an intervention in motivation biology can be considered positivefor human morality. To overcome this difficulty, this paper identifiesminimal requirements for moral enhancement that could be accepted bythe major moral theories. Subsequently four possible scenarios are presentedwhere the most promising neural interventions on moral motivationare implemented, by means of drugs, electromagnetic stimulation ofbrain, or biotechnological brain implants. The ultimate goal of this paperis (...) to evaluate the results of each one of these interventions according totheir capacity to fulfill the identified requirements. (shrink)
