Since 1992, the Dia Center for the Arts has presented the Robert Lehman Lectures on Contemporary Art--an example of Dia's ongoing commitment to cross-disciplinary critical and intellectual discourse. The long-term, often site-specific exhibitions at Dia offer a fertile space for discussion. Edited by Lynne Cooke and Karen Kelly, with Barbara Schroder, this fourth volume of collected theoretical and critical essays again focus on Dia's exhibitions from 2001 through 2002. It includes ten diverse international contributions by Alexander Alberro, Jan Avgikos, Colin Gardner, Dave Hickey, Rosalind Krauss, Miwon Kwon, Ulrich Loock, Richard Shiff and Dirk Snauwaert. These writers, among others, take on the challenges of illuminating, analyzing and exploring the work of a disparate group of internationally recognized artists, including Roni Horn, Alfred Jensen, Bruce Nauman, Max Neuhaus, Panamarenko, Jorge Pardo, Gerhard Richter, Bridget Riley, Diana Thater and Gilberto Zorio. Together, the essays in this book present a broad account of contemporary artistic practice, criticism, scholarship and theory.
