Sarah Williams Goldhagen, architecture critic at The New Republic has a splendid review of and essay on several, recently completed public parks (including Chicago's Millennium Park, pictured below). Like the environmental artist Christo, Goldhagen, in this and other essays, treats of the political, social, and economic work that gives rise to architectures and the the political, social, and economic work done by architectures. She thus treats, in my mind, the double work of rhetoric and materiality. The architecture,as the material, works to shape the public, its movements, its values, and its future. However, the material, the architecture is not pre-specified and automatic: it must be made and it is made rhetorically.
