There might not be a specific nano-ethics, but there definitely is an ethics of new & emerging science and technology (NEST), with characteristic tropes and patterns of moral argumentation. Ethical discussion in and around nanoscience and technology reflects such NEST-ethics. We offer an inventory of the arguments, and show patterns in their evolution, in arenas full of proponents and opponents. We also show that there are some nano-specific issues: in how size matters, and when agency is delegated to smart devices. (...) Our overall approach is a pragmatist ethics, and we conclude that struggle (and learning) might be more productive than models emphasizing consensus. (shrink)

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.

The emergence and development of convergent technologies for the purpose of improving human performance, including nanotechnology, biotechnology, information sciences, and cognitive science (NBICs), open up new horizons in the debates and moral arguments that must be engaged by philosophers who hope to take seriously the question of the ethical and social acceptability of these technologies. This article advances an analysis of the factors that contribute to confusion and discord on the topic, in order to help in understanding why arguments that (...) form a part of the debate between transhumanism and humanism result in a philosophical and ethical impasse: 1. The lack of clarity that emerges from the fact that any given argument deployed (arguments based on nature and human nature, dignity, the good life) can serve as the basis for both the positive and the negative evaluation of NBICs. 2. The impossibility of providing these arguments with foundations that will enable others to deem them acceptable. 3. The difficulty of applying these same arguments to a specific situation. 4. The ineffectiveness of moral argument in a democratic society. The present effort at communication about the difficulties of the argumentation process is intended as a necessary first step towards developing an interdisciplinary response to those difficulties.
