by the lab studies; the power of laboratories (and engineering workshops) to change the world as we know and experience it; the seamless webs that connect scientists, engineers and societal actors in actual practice (cf. John Law's concept of heterogeneous engineering); the propensity of technoscientific world to create new nature–culture hybrids, and hence to complicate the borders between nature and culture. Conceptual levels of philosophical technoscience We look at the concept of technoscience by considering three levels: a descriptive-analytic level, a deconstructivist level, and a visionary level. Descriptive-analytic On a descriptive-analytic level, technoscientific studies examine the decisive role of science and technology in how knowledge is being developed. What is the role played by large research labs in which experiments on organisms are undertaken, when it comes to a certain way of looking at the things surrounding us? To what extent do such investigations, experiments and insights shape views of 'nature' and of human bodies? How do these insights link to the concept of living organisms as biofacts? To what extent do such insights inform technological innovation? Can the laboratory be understood as a metaphor for social structures in their entirety? Deconstructive On a deconstructive level, theoretical work is being undertaken on technoscience to address scientific practices critically, e.g. by Bruno Latour (sociology), by Donna Haraway (history of science), and by Karen Barad (theoretical physics). It is pointed out that scientific descriptions may be only allegedly objective; that descriptions are of a performative character, and that there are ways to de-mystify them. Likewise, new forms of representing those involved in research are being sought. Visionary On a visionary level, the concept of technoscience comprises a number of social, literary, artistic and material technologies from western cultures in the third millennium. This is undertaken in order to focus on the interplay of hitherto separated areas and to question traditional boundary-drawing: this concerns the boundaries drawn between scientific disciplines as well as those commonly upheld for instance between research, technology, the arts and politics. One aim is to broaden the term 'technology' (which by the Greek etymology of 'techné' connotes all of the following: arts, handicraft, and skill) so as to negotiate possibilities of participation in the production of knowledge and to reflect on strategic alliances. Technoscience can be juxtaposed with a number of other innovative interdisciplinary areas of scholarship which have surfaced in these recent years such as technoetic, technoethics and
