 Koselleck’s work defines a separate space within the field of the philosophy of history. It has to do with meanings in history, but it is neither teleological nor hermeneutic. It takes seriously the obligation of the historian excavate the historical facts with scrupulous rigor, but it is not empiricist or reductionist. It emphasizes the dependence of “history” on the conceptual resources of those who live history and those who tell history, but it is not post-modernist or relativist. Koselleck provides an innovative and constructive way of formulating the problem of historical knowledge.
