Scientists and engineers who extensively use the term “nanomachine” are not always aware of the philosophical implications of this term. The purpose of this paper is to clarify the concept of nanomachine through a distinction between three major paradigms of machine. After a brief presentation of two well-known paradigms - Cartesian mechanistic machines and Von Neumann's complex and uncontrolled machines – we will argue that Drexler's model was mainly Cartesian. But what about the model of his critics? We propose a (...) third model - Gilbert Simondon's notion of concrete machines – which seems more appropriate to understand nanomachines than the notion of “soft machines”. Finally we review a few strategies currently used to design nanomachines, in an effort to determine which paradigm they belong to. (shrink)

Nanotechnology seems to be a new "key-discipline", which should lead to basic changes in many areas of living and producing. This estimation is questioned by a comparison with established technologies, which reach from heat engines to biotechnology. In this line it is possible to come to a more realistically assessment of nanotechnology. "Technologies" in the narrower sense are understood as techniques based scientifically and integrated systematically into a network. The development of these technologies starts first in the early modern times. (...) Before this background the established technologies are characterised looking at relevant questions and problems, the role of researchers and inventors, the importance of theoretical foundations, important applications and innovations, as well as the relevance of visions and then confronted with nanotechnology in its present state. It is accentuated that there are no explicit theories and no specific applications of nanotechnology and it seems to be only a kind of chemical technology. (shrink)
