A controversial scientific vision predicts a time in which humans and machines will merge and create a new form of non-biological intelligence, explaining how the occurrence will solve such issues as pollution, hunger, and aging.

How are we to understand the fact that the philosophical debate over nanotechnologies has been reduced to a clash of seemingly preprogrammed arguments and counterarguments that paralyzes all rational discussion of the ultimate ethical question of social acceptability in matters of nanotechnological development? With this issue as its starting point, the study reported on here, intended to further comprehension of the issues rather than provide a cause-and-effect explanation, seeks to achieve a rational grasp of what is being said through the (...) appeals made to this or that principle in the range of arguments put forward in publications on the subject. We present the results of the study’s analyses in two parts. In the first, we lay out the seven categories of argument that emerged from an analysis of the literature: the arguments based on nature, dignity, the good life, utility, equity, autonomy, and rights. In the second part, we present the background moral stances that support each category of argument. Identifying the different categories of argument and the moral stance that underlies each category will enable a better grasp of the reasons for the multiplicity of the arguments that figure in discussions of the acceptability of nanotechnologies and will ultimately contribute to overcoming the tendency towards talking past each other that all too often disfigures the exchange. Clarifying the implications of the moral arguments deployed in the debate over nanotechnologies may make it possible to reduce the confusion observable in these exchanges and contribute to a better grasp of the reasons for their current unproductiveness.

After reviewing portions of the 21st Century Nanotechnology Research and Development Act that call for examination of societal and ethical issues, this essay seeks to understand how nanoethics can play a role in nanotechnology development. What can and should nanoethics aim to achieve? The focus of the essay is on the challenges of examining ethical issues with regard to a technology that is still emerging, still ‘in the making.’ The literature of science and technology studies (STS) is used to understand (...) the nanotechnology endeavor in a way that makes room for influence by nanoethics. The analysis emphasizes: the contingency of technology and the many actors involved in its development; a conception of technology as sociotechnical systems; and, the values infused (in a variety of ways) in technology. Nanoethicists can be among the many actors who shape the meaning and materiality of an emerging technology. Nevertheless, there are dangers that nanoethicists should try to avoid. The possibility of being co-opted from working along side nanotechnology engineers and scientists is one danger that is inseparable from trying to influence. Related but somewhat different is the danger of not asking about the worthiness of the nanotechnology enterprise as a social investment in the future. (shrink)

Far-reaching promises made by nanotechnology have raised the question of whether we are on the way to understanding human beings more and more as belonging to the realm of technology. In this paper, an increasing need to understand the technological re-conceptualization of human beings is diagnosed whenever increasingly “technical” interpretations of humans as mechanical entities are disseminated. And this can be observed at present in the framework of nanobiotechnology, a foremost “technical” self-description where a technical language is adopted. The arena (...) in which the decision is made on increasing the use of technological understanding to define mankind will not be found in the surgery room in which one works with implants, nor the NBIC-laboratory, in which “nerve plugs” are supposed to be developed. The thesis of this paper is that such arena is rather related to the manner in which concepts of humanity are associated with it, how we think and talk about ourselves, and which consequences we draw out of it.

If such a thing as nanoethics is possible, it can only develop by confronting the great questions of moral philosophy, thus avoiding the pitfalls so common to regional ethics. We identify and analyze some of these pitfalls: the restriction of ethics to prudence understood as rational risk management; the reduction of ethics to cost/benefit analysis; the confusion of technique with technology and of human nature with the human condition. Once these points have been clarified, it is possible to take up (...) some weighty philosophical and metaphysical questions which are not new, but which need to be raised anew with respect to nanotechnologies: the artificialization of nature; the question of limits; the role of religion; the finiteness of the human condition as something with a beginning and an end; the relationship between knowledge and know-how; the foundations of ethics.

This paper, guided by the UNESCO Universal Declaration on Bioethics and Human Rights, assumes that regulators should aim to support the development of nanomedicine while, at the same time, putting in place whatever limits or safeguards are indicated by ethical considerations. Relative to this regulatory objective, it is argued that, notwithstanding the importance of precaution (characteristically, concerning health, safety, and the environment), ethical reflection needs to go both broader and deeper. It is suggested that, by attending to the basic matrix (...) of ethical debate and the “bioethical triangle” through which the matrix is currently articulated, the breadth, depth, and conflictual plurality of ethical concerns about nanomedicine will be clarified. In this light, the conventional thinking about precaution is revisited and concerns about human dignity and informed consent (under conditions of extreme uncertainty) are analysed. The paper concludes that, once the range of ethical pluralism is grasped, the extent of the challenge facing regulators will be more clearly appreciated. (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 presents the principal findings from a three-year research project funded by the US National Science Foundation on ethics of human enhancement technologies. To help untangle this ongoing debate, we have organized the discussion as a list of questions and answers, starting with background issues and moving to specific concerns, including: freedom & autonomy, health & safety, fairness & equity, societal disruption, and human dignity. Each question-and-answer pair is largely self-contained, allowing the reader to skip to those issues of (...) interest without affecting continuity. (shrink)

A half-billion years ago, a few species of single-celled protozoa stumbled irreversibly from loose social interaction into a tight, specialized interdependence. They became multi-celled metazoa, and human beings are one sort. Metazoa greatly transcend their constituent cells in lifetime, abilities, experiences and even materials (like bone). New kind of beings emerged out of the interactions of the old.
