We're pleased to announce that Jason Brennan has accepted our invitation to become a contributor. Here's a brief biography, which I borrow from his web site: "JASON BRENNAN (Ph.D., 2007, University of Arizona) is Assistant Professor of Philosophy, Research, at Brown University, and a member of the Political Theory Project, an interdisciplinary research center at Brown. He specializes in metaethics, normative ethics, and political philosophy. His current research is on voting ethics, and he is developing a new liberal, pluralistic theory of civic virtue that emphasizes the public value of private, non-political activity. Together with David Schmidtz, he is the author of A Brief History of Liberty, forthcoming from Blackwell in August 2009. His second book, The Ethics of Voting, is under contract with Princeton University Press." Please join me in welcoming Jason.
