The new issue of Political Theory has an interesting piece on Reinhart Koselleck‘s notion of conceptual history (Begriffsgeschichte) and the relation this has to Carl Schmitt’s work. I quite like Koselleck’s work – or at least the basic idea behind it – though there are some problematic politics at play. Koselleck also kept some suspect company – his colleague Otto Brunner was a Nazi too. This piece raises some nasty questions.
