Research on moral judgment has been dominated by rationalist models, in which moral judgment is thought to be caused by moral reasoning. The author gives 4 reasons for considering the hypothesis that moral reasoning does not cause moral judgment; rather, moral reasoning is usually a post hoc construction, generated after a judgment has been reached. The social intuitionist model is presented as an alternative to rationalist models. The model is a social model in that it deemphasizes the private reasoning done (...) by individuals and emphasizes instead the importance of social and cultural influences. The model is an intuitionist model in that it states that moral judgment is generally the result of quick, automatic evaluations (intuitions). The model is more consistent than rationalist models with recent findings in social, cultural, evolutionary, and biological psychology, as well as in anthropology and primatology. (shrink)

There is concern that the use of neuroenhancements to alter character traits undermines consumer's authenticity. But the meaning, scope and value of authenticity remain vague. However, the majority of contemporary autonomy accounts ground individual autonomy on a notion of authenticity. So if neuroenhancements diminish an agent's authenticity, they may undermine his autonomy. This paper clarifies the relation between autonomy, authenticity and possible threats by neuroenhancements. We present six neuroenhancement scenarios and analyse how autonomy accounts evaluate them. Some cases are considered (...) differently by criminal courts; we demonstrate where academic autonomy theories and legal reasoning diverge and ascertain whether courts should reconsider their concept of autonomy. We argue that authenticity is not an appropriate condition for autonomy and that new enhancement technologies pose no unique threats to personal autonomy. (shrink)

Opponents of biomedical enhancement often claim that, even if such enhancement would benefit the enhanced, it would harm others. But this objection looks unpersuasive when the enhancement in question is a moral enhancement — an enhancement that will expectably leave the enhanced person with morally better motives than she had previously. In this article I (1) describe one type of psychological alteration that would plausibly qualify as a moral enhancement, (2) argue that we will, in the medium-term future, probably be (...) able to induce such alterations via biomedical intervention, and (3) defend future engagement in such moral enhancements against possible objections. My aim is to present this kind of moral enhancement as a counter-example to the view that biomedical enhancement is always morally impermissible. (shrink)

Transhumanists advance a "posthuman" condition in which technological and genetic enhancements will transform humankind. They are joined in this goal by bioethicists arguing for genetic selection as a means of "enhancing evolution," improving if not also the species then at least the potential lives of future individuals. The argument of both, this paper argues, is a new riff on the old eugenics tune. As ever, it is done in the name of science and its presumed knowledge base. As ever, the (...) result is destructive rather than instructive, bad faith promoted as high ideal. The paper concludes with the argument that species advancement is possible but in a manner thoroughly distinct from that advanced by either of these groups. (shrink)

abstract As history shows, some human beings are capable of acting very immorally. 1 Technological advance and consequent exponential growth in cognitive power means that even rare evil individuals can act with catastrophic effect. The advance of science makes biological, nuclear and other weapons of mass destruction easier and easier to fabricate and, thus, increases the probability that they will come into the hands of small terrorist groups and deranged individuals. Cognitive enhancement by means of drugs, implants and biological (including (...) genetic) interventions could thus accelerate the advance of science, or its application, and so increase the risk of the development or misuse of weapons of mass destruction. We argue that this is a reason which speaks against the desirability of cognitive enhancement, and the consequent speedier growth of knowledge, if it is not accompanied by an extensive moral enhancement of humankind. We review the possibilities for moral enhancement by biomedical and genetic means and conclude that, though it should be possible in principle, it is in practice probably distant. There is thus a reason not to support cognitive enhancement in the foreseeable future. However, we grant that there are also reasons in its favour, but we do not attempt to settle the balance between these reasons for and against. Rather, we conclude that if research into cognitive enhancement continues, as it is likely to, it must be accompanied by research into moral enhancement. (shrink)

Positions on the ethics of human enhancement technologies can be (crudely) characterized as ranging from transhumanism to bioconservatism. Transhumanists believe that human enhancement technologies should be made widely available, that individuals should have broad discretion over which of these technologies to apply to themselves, and that parents should normally have the right to choose enhancements for their children-to-be. Bioconservatives (whose ranks include such diverse writers as Leon Kass, Francis Fukuyama, George Annas, Wesley Smith, Jeremy Rifkin, and Bill McKibben) are generally (...) opposed to the use of technology to modify human nature. A central idea in bioconservativism is that human enhancement technologies will undermine our human dignity. To forestall a slide down the slippery slope towards an ultimately debased ‘posthuman’ state, bioconservatives often argue for broad bans on otherwise promising human enhancements. This paper distinguishes two common fears about the posthuman and argues for the importance of a concept of dignity that is inclusive enough to also apply to many possible posthuman beings. Recognizing the possibility of posthuman dignity undercuts an important objection against human enhancement and removes a distortive double standard from our field of moral vision. (shrink)

This paper reviews the evolutionary history and biology of love and marriage. It examines the current and imminent possibilities of biological manipulation of lust, attraction and attachment, so called neuroenhancement of love. We examine the arguments for and against these biological interventions to influence love. We argue that biological interventions offer an important adjunct to psychosocial interventions, especially given the biological limitations inherent in human love.

‘Applied ethics’, as that expression is now used, is a single rubric for a large range of different theoretical and practical activities. Such rubrics function partly as a protective device both within the academic community and outside it; a name of this kind suggests not just a discipline, but a particular type of discipline. In the case of ‘applied ethics’ the suggestive power of the name derives from a particular conception of the relationship of ethics to what goes on under (...) the rubric of ‘applied ethics’. Not everyone who conducts activities under that rubric owes allegiance to this conception and there are doubtless some who would repudiate it as strongly as I do. But it is that dominant conception from which most work in this area derives or aspires to derive its philosophical legitimacy. What is that conception? (shrink)

Sunstein is right that poorly informed heuristics can influence moral judgment. His case could be strengthened by tightening neurobiologically plausible working definitions regarding what a heuristic is, considering a background moral theory that has more strength in wide reflective equilibrium than “weak consequentialism,” and systematically examining what naturalized virtue theory has to say about the role of heuristics in moral reasoning.

PurposeSince the 1980s we have witnessed a soaring “extra-therapeutic” use of psycho-pharmacology. But there is also an increasing interest in invasive methods of neuroenhancement that can be subsumed under the term “brain engineering”. The present article aims to identify key issues raised by those forms of neuro-technical enhancement (e.g., deep brain stimulation, brain-computer interfaces, memory chips, neurobionic interventions). First it distinguishes different forms of neuroenhancement, then describes features of those methods and finally discusses their ethical implications.MethodsThe article is based on (...) an in-depth literature study and an ethical assessment of the current and emerging forms of neuroenhancement.ResultsFrom a medical and normative perspective, psycho-pharmacological enhancement and nonpharmacological enhancement by brain engineering demonstrate considerable differences. Many arguments in favour of nonpharmacological enhancement fall short, for they fail to sufficiently consider the medical, anthropological and socio-cultural context. In many respects unsecured use is confronted with considerable risks.ConclusionsResearch on invasive forms of neuroenhancement partly takes place in the fields of (nano-)technology and military, to which health care experts and medical ethicists do not have easy access. This raises the danger of misjudging trends and developmental tendencies. Thus medicine and medical ethics must a priori thematize the goals and risks linked to these questions as well as participate discursively right from the beginning. (shrink)
