In times of crisis of democracy, the concept of public sphere proves to be useful again to generate understanding about the challenges that arise. Whether due to the saturated fragmentation of discursive flows on digital platforms, the explosion of phenomena linked to disinformation, the centrality acquired by non-human entities in structuring today’s public opinion, or the social struggles and the thematization of public problems as they have been organized, behold, the notion is taken up again, 60 years after the publication of Structural Change in the Public Sphere, to talk about the chances of survival of democracy. This book brings together a set of chapters that propose to mobilize the concept of the public sphere and deliberationist lenses, to read not only the broader picture of democratic erosion, but also the reconfigurations of communication practices and public clashes that mark the contemporary world.
