ABSTRACTIn recent work, Maeve Cooke has criticised Jürgen Habermas’s post-metaphysical model in order to motivate an alternative “post-secular” conception of the state, which involves the replacement of the “institutional translation proviso” with the “nonauthoritarian reasoning requirement”. I provide a qualified defence of the Habermasian model by arguing that it does not lead to the kind of negative consequences regarding legitimacy and solidarity Cooke attributes to it. This, in turn, means that Cooke’s proposal for the secular foundation of political authority on (...) a post-secular basis is insufficiently motivated. In the process, I argue that the point of departure for the debate about religion in the public sphere shared by both Habermas and Cooke – the picture of the “total” religious citizen – should be rejected because it presupposes an overly simplistic view of religions and religious identities.
