Social Ecology articles available

Previously unavailable works by social ecologists Peter Staudenmaier, Ben Grosscup, and Karl Hardy covering a broad range of topics can now be accessed in the Institute for Social Ecology’s website Article Archive.
Staudenmaier’s pieces include his critical historical essays on anthroposophy, his participation in Left debates over Kosovo, and his involvement in a “Social Ecology vs. Participatory Economics” debate with Michael Albert, the founder of PARECON.
The two articles authored by Grosscup posit a radical critique of the response to Hurricane Katrina and the 2004 election cycle, respectively.
Hardy offers a book review of the posthumously-released “Social Ecology and Communalism,” a collection of essays by Murray Bookchin, and an analysis of progressive candidacies during the 2008 US presidential race.
