SUMMARYIn recent years students of politics have begun to recognise Reinhart Koselleck's practice of Begriffsgeschichte, the study of conceptual history, as a useful approach for investigating key concepts in political ideologies and the history of ideas. But his theory of historical time—the temporal dimension to his semantic project and his broader theorising of the historical discipline—is often overlooked and underused as a heuristic device. By placing the thinking of Michael Oakeshott alongside Koselleck's theory of historical time, this article brings his (...) thinking on temporality to the forefront, fashioning a conversation between the two thinkers about the place for history and the formal criteria necessary for ordering the past properly. In doing so, it juxtaposes Koselleck's reflections on historicity and his theory of historical time with Oakeshott's philosophical enquiry on the historical mode of understanding. It identifies important convergences and divergences between the two thinkers' theories, focusing in particular on questions regarding the potential for representing the past as multilayered and plural historical times. The article then suggests that their respective thoughts on the theory of history are in part a reaction to the modern politicisation of historical time and comprise a shared critique of radical political change.
