The assemblies of the numerous square occupations during the last decade have often been laboratories of radical forms of democracy, experimenting with non-hierarchical structures and consensus models instead of majority voting. While watching these movements with sympathy, political theorist Chantal Mouffe emphasises also the necessity of dissensus, of an agonistic pluralism in which adversaries openly fight for their hegemonic projects. Philosopher and sociologist Didier Eribon reflects on the conditions and the limits of such mobilisations and insists on the unsurpassable plurality of movements like the gilets jaunes in France, or more recently, the massive strikes and protests against the demolition of the public sector, as well as the demonstrations against racism etc. In the 7th edition of “The Art of Assembly” Eribon and Mouffe discuss how much agonism social movements can bare and how the diversity of democratic demands should be addressed.
