Avant-garde theorist and architect Bernard Tschumi is equally well known for his writing and his practice. Architecture and Disjunction, which brings together Tschumi's essays from 1975 to 1990, is a lucid and provocative analysis of many of the key issues that have engaged architectural discourse over the past two decades&mdash;from deconstructive theory to recent concerns with the notions of event and program.<br /><br />The essays develop different themes in contemporary theory as they relate to the actual making of architecture, attempting to realign the discipline with a new world culture characterized by both discontinuity and heterogeneity. Included are a number of seminal essays that incited broad attention when they first appeared in magazines and journals, as well as more recent and topical texts.<br /><br />Tschumi's discourse has always been considered radical and disturbing. He opposes modernist ideology and postmodern nostalgia since both impose restrictive criteria on what may be deemed &quot;legitimate&quot; cultural conditions. He argues for focusing on our immediate cultural situation, which is distinguished by a new postindustrial &quot;unhomeliness&quot; reflected in the ad hoc erection of buildings with multipurpose programs. The condition of New York and the chaos of Tokyo are thus perceived as legitimate urban forms.
