The essay is better for comments by participants at: the 2004 annual
meeting of the American Political Science Association, especially Ann Davies,
discussant; the Montreal Political Theory Workshop, Matthias Risse, discussant; the
University of Chicago Political Theory Workshop, Zachary Callen, discussant. Written
comments by David Estlund, Jeffrey E. Green, and Scott Mainwaring, the editor, and
reviewers offered several insights and corrections. I am responsible for the contents.
