This paper examines critical concepts developed by the architect Frederick Kiesler and the critic-historian Siegfried Giedion for their relevance to that discourse. Kiesler’s principle of Correalism and Gieidon’s appeal for Equipoise offer both a prehistory to the current mandates about sustainability and cautions about its limitations. The sustainable is ultimately a social condition that cannot be applied therapeutically nor ever wholly institutionalized.correalismequipoisesustainablegiedionkieslerbrahamArchitectureDemography, Population, and EcologyEcology and Evolutionary BiologyArticleARRAY(0x55e101254e78)
