Abstract
The history of concepts has partly replaced the older style of the `history of ideas' and can be extended to a critique of normative political theory and, thereby, understood as an indirect style of political theorizing. A common feature in Quentin Skinner's and Reinhart Koselleck's writings lies in their critique of the unhistorical and depoliticizing use of concepts. This concerns especially the classical contractarian theories, and both authors remark that this still holds for work by their contemporary heirs, such as Rawls, Habermas and other contemporary normative theorists. Conceptual history offers us a chance to turn the contestability, contingency and historicity of the use of concepts into instruments for conceptualizing politics. The alternative, indirect mode of political theorizing Skinner and Koselleck practise consists of a `Verfremdungseffekt', which helps us to distance ourselves from thinking in terms of contemporary paradigms, unquestioned conventions, given constellations of alternatives or implicit value judgements. In the Skinnerian variant the conceptual changes are made intelligible through analysis of the rhetorical redescriptions among the political agents, whereas Koselleck thematizes the differences in the temporal index of concepts. The subversive aspect in the history of concepts consists of the explication and historical variation of the tacit normative content in the use of concepts.
