The “public sphere” is a key concept in political discourse, designating a space for political action. But is this a single authoritative and universal space in which various positions compete for recognition, or does it consist of multiple local spaces spread over diverse collectivities?

With a new, up-to-date introduction from Alexander Kluge.
