Abstract
I have a long-standing relation with the noun “technoscience.” In recent years, I have been concerned with its evolution and connotations, since the period when I first thought it up. This chapter presents a survey of the various uses, transfers and significations of the term. It makes a twofold claim technoscientific research and development are conducted by a plural subject in need of a moral conscience; the study of technoscientific objects requires a methodological and operational materialism.Augmented version for this volume of an essay first published in French Regards sur les technosciences, Vrin, Paris, pp. 23–38, 2006).
