Correalism and Equipoise: observations on the sustainable

Modern environmentalism originates with the recognition of ecological connectivity and the negative effects of technological intervention. This paper examines critical concepts developed by the architect Frederick Kiesler and the critic-historian Sigfried Giedion for their relevance to that discourse. Kiesler's principle of Correalism and Giedion'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.
