Transnationalizing the public sphere - On the legitimacy and efficacy of public opinion in a post-Westphalian world

As a critical concept, the public sphere has always been premised on two idealizing assumptions: in principle, public opinion should be normatively legitimate and politically efficacious. Yet these assumptions are hard to associate with the discursive arenas we today call 'transnational public spheres', which neither stage communication among equal citizens nor address it to sovereign states. In this context, public sphere theory is in danger of losing its critical thrust and political point. Aiming to recover its critical potential, this article revisits the ideals of legitimacy and efficacy in three steps. First, I explicate the implicit Westphalian presuppositions of Habermas's original formulation and show that these have persisted in its major feminist, anti-racist and multicultural critiques, including my own. Second, I identify several distinct facets of transnationality that problematize the understandings of legitimacy and efficacy that informed both the original theory and its critical counter-theorizations. Finally, I suggest a strategy for reconstructing the ideal of legitimate and efficacious public opinion for a post-Westphalian world.
