This is the fourth volume of Oxford Studies in Political Philosophy. Since its revival in the 1970s political philosophy has been a vibrant field in philosophy, one that intersects with jurisprudence, normative economics, political theory in political science departments, and just war theory. OSPP aims to publish some of the best contemporary work in political philosophy and these closely related subfields. This volume features eight papers that address a range ofcentral topics and represent cutting edge work in the field. The three parts of the volume explore legitimacy, egalitarianism, and liberty and coercion.
