This article reviews recent work in socio-historical technology studies. Four problems, frequently mentioned in critical debates, are discussed – relativism, reflexivity, theory, and practice. The main body of the article is devoted to a discussion of the latter two problems. Requirements for a theory on socio-technical change are proposed, and one concrete example of a conceptual framework that meets these requirements is discussed. The second point of the article is to argue that present (science and) technology studies arc now able to break away from a too academic, internalistic perspective and return to the politically relevant “Science, Technology & Society” issues that informed much of this work more than a decade ago.
