This paper analyses rhetorics of scientific and corporate enthusiasm surrounding nanotechnology. I argue that enthusiasts for nanotechnologies often try to have it both ways on questions concerning the nature and possible impact of these technologies, and the inevitability of their development and use. In arguments about their nature and impact we are simultaneously informed that these are revolutionary technologies with the potential to profoundly change the world and that they merely represent the extension of existing technologies. They are revolutionary and (...) familiar. In debates surrounding possible regulation of these technologies it is claimed both that their development is inevitable, so that regulation would be fruitless, and that increased research funding and legislative changes are necessary in order that we can enjoy their benefits. That is, they are inevitable and precarious. An increased awareness of these rhetorical contradictions may allow us better to assess the likely impact and future of nanotechnology. (shrink)

Emerging developments in communications and computing technology may transform the nature of human identity, in the process rendering obsolete the traditional philosophical and scientific frameworks for understanding the nature of individuals and groups. Progress toward an evaluation of this possibility and an appropriate conceptual basis for analyzing it may be derived from two very different but ultimately connected social movements that promote this radical change. One is the governmentally supported exploration of Converging Technologies, based in the unification of nanoscience, biology, (...) information science and cognitive science. The other is the Transhumanist movement, which has been criticized as excessively radical yet is primarily conducted as a dignified intellectual discussion within a new school of philosophy about human enhancement. Together, NBIC and Transhumanism suggest the immense transformative power of today’s technologies, through which individuals may explore multiple identities by means of online avatars, semi-autonomous intelligent agents, and other identity expansions.
