This week my graduate seminar students (at Parsons Fine Arts MFA) and I had a great discussion leading from Robert Smithson's writings on entropy to issues of pessimism about social change and what might be the point of human intervention towards ideals of progressive social activism in an entropically irreversible situation: interesting in this light to read Bob Herbert Op-Ed piece in the October 26, 2010 copy of The New York Times, "The Corrosion of America": do we just go along "haplessly"/hopelessly with the flow of entropy and the corrosion and ruin of our infrastructure (a ruin which is in a sense "always already" from before its inception, in Smithson's example of "The Monuments of Passaic") creating or suggesting an art which does not try to impose an idealist order or moral value to an entropic situation of urban and suburban decay, or do we believe enough in human labor despite ultimate futility or mortality to make the investment in our near futures by fixing the infrastructure?
