This article was presented as the keynote speech to the conference “The Politics of Social Ecology: Libertarian Municipalism” held in Plainfield, Vermont, U.S.A., on August 26-29, 1999. The speech has been revised for publication. This article originally appeared in Left Green Perspectives (Number 41, January 2000). Some issues have recently arisen in discussions of libertarian municipalism, and I would like to offer my views on them. One of the most important involves the distinction that should be drawn between libertarian municipalism and communitarianism, a distinction that is often lost in discussions of politics.
