This title explores the desire to move viewers out of the role of passive observers and into the role of producers. Participation begins with writings that provide a theoretical framework for relational art, with essays by Umberto Eco, Roland Barthes, Peter Bürger, Jean-Luc Nancy, Edouard Glissant, Félix Guattari, as well as the first translation into English of Jacques Rancière’s influential ‘Problems and Transformations in Critical Art’. This anthology also includes central writings by such artists as Lygia Clark and Hélio Oiticica, Joseph Beuys, Felix Gonzalez-Torres, Thomas Hirschhorn, Rirkrit Tiravanija, and features recent critical and curatorial debates, with discussions by Lars Bang Larsen, Nicolas Bourriaud, Hal Foster and Hans-Ulrich Obrist.
