The notion of a ‘ public sphere ’, developed in the work of Jürgen Habermas (1974), is an important touchstone for social theorists of democracy and public life. It has given rise to a critical literature that engages with the concept of a ‘public sphere’ and seeks to assess its historical validity and contemporary relevance. This discussion has developed parallel to wider debates on the public/private distinction, the interrelationship between the public realm and private life , and the organization of public and private spaces. The present review will group the literature in terms of approach and delineate common points of analysis and areas of contestation, moving onto a detailed analysis of selected texts that can offer guidance for future research on the contemporary utility of the concept of the ‘public sphere’.
