†Previous versions of this article were presented at “Articulations of Justice (2): Justice and Equality,” Macquarie University, Sydney, Australia, July 2011, and at the annual meetings of the Association for Political Theory, Portland, OR, October 2010, and the American Political Science Association, Washington, DC, September 2010. I am grateful to the audiences and to my co-panelists on those occasions, and in particular to Mark Brown and Melissa Schwartzberg, for their comments and criticisms. Michael Fuerstein, Michael Neblo and Piers Turner provided invaluable feedback on subsequent versions. Thanks are also due to Bob Goodin and the anonymous referees for the Journal of Political Philosophy. The errors that remain are entirely my own.
