<p>Jack Burnham is one of the few critics and theorists alive today who can claim to have radically altered the way we think about works of art. Burnham's use of the term &quot;system&quot; (borrowed from theoretical biology) in his 1968 essay &quot;System Aesthetics&quot; announced the relational character of conceptual art and newer research-based projects. Trained as an art historian, Burnham was also a sculptor. His first book,<i>Beyond Modern Sculpture</i> (1968), established him as a leading commentator on art and technology. A postformalist pioneer, an influential figure in new media art history, an early champion of conceptual and ecological art, and the curator of the first exhibition of digital art, Burnham is long overdue for reevaluation. This book offers that opportunity by collecting a substantial and varied selection of his hard-to-find texts, some published here for the first time.</p><p>Although Burnham left the art world abruptly in the 1990s, his visionary theoretical ideas have only become more relevant in recent years. This collection seeks to restore Burnham to his rightful place in art criticism and theory, reestablishing his voice as crucial to critical conversations of the period. It gathers his early writing on sculpture, his essays on systems art and conceptualism, his views of the New York art world, and his later occult work -- including an unorthodox interpretation of Marcel Duchamp's work that draws on the Kabbalah. </p>
