There is currently a renewed interest in 'cosmopolitanism' in contemporary sociology and a number of analyses are condensing into a new paradigm of 'Cosmopolitan Sociology'. Current analyses of the social are united by at least three interconnected commitments - a critique of 'methodological nationalism', a belief that the 21st century is a cosmopolitan age and an acceptance of the need for some kind of 'methodological cosmopolitanism'. The new paradigm amounts to the emergence of a non-nostalgic New Critical Theory which investigates the social and political grammar of today's cosmopolitan condition.
