"The Great Repair" is an oxymoron. The title captures the convergence of two seemingly contradictory principles: the revolutionary ambition for systemic change and the evolutionary act of repair. Despite the justified (postmodern) skepticism toward revolution as a concept of rupture, we must not abandon our aspiration to bring about profound transformation. The philosopher Eva von Redecker formulates this thought along similar lines in this issue:Two English language issues of ARCH+ Magazine for Architecture and Urbanism are published in collaboration with Spector Books to accompany the exhibition. The first issue (ARCH+ The Great Repair - Politics of the Repair Society, May 2023) serves as a theoretical introduction to the topic, while the second (ARCH+ The Great Repair - A Catalog of Practices) introduces practices of repair and will be published on the occasion of the exhibition's opening as a catalog.
