 A large part of Koselleck’s work thus involves identifying and describing various kinds of historical concepts. In order to represent history it is necessary to make use of a vocabulary that distinguishes the things we need to talk about; and historical concepts permit these identifications. This in turn requires both conceptual and historical treatment: how the concepts are understood, and how they have changed over time. Christophe Bouton encapsulates Koselleck’s approach in these terms: “[It is an] inquiry into the historical categories that are used in, or presupposed by, the experience of history at its different levels, as events, traces, and narratives” (Bouton 2016: 164). Further, Bouton argues that Koselleck also brings a critical perspective to the concepts that he discusses: he asks the question of validity (Bouton 2016). To what extent do these particular concepts work well to characterize history?
