Chantal Mouffe asserts that rethinking such frontiers is essential; not so much between left and right, but between the oligarchy and the society dispossessed in this process. Art and its institutions, in their capacity of collective representation, play a key role in this tract. At the other end, Didier Eribon wholly rejects the new binary opposites between those at the top and those at the bottom, scotching their uniformity in the excess of a complex and diverse social body, and maintaining a return to the notion of difference and the critique of the place of enunciation (those who speak and from where), characterising the so-called cultural wars from the 1970s. Both authors will, first and foremost, present these two positions before debating them. This conversation is part of the Dialogues programme held by the museum confederation L’Internationale, made up of Van Abbemuseum (Eindhoven), the Museum Hedendaagse Kunst Antwerpen (Antwerp), the Moderna galerija (Ljubljana), SALT (Istanbul), the Museu d’ Art Contemporani de Barcelona (Barcelona) and the Museo Reina Sofía (Madrid).
