Even though political philosophy has a long tradition, it is much more than the study of old and great treatises. Contemporary philosophers continue to press new arguments on old and timeless questions, but also to propose departures and innovations. The field changes over time, and new work inevitably responds both to events in the world and to the directions of thought itself. This volume includes 22 new pieces by leaders in the field on both perennial and emerging topics of keen interest to contemporary political philosophers. In addition to longstanding issues such as Authority, Equality, and Freedom, and Democracy, there are articles on less classical topics such as Race, Historical Injustice, Deliberation, Money and Politics, Global Justice, and Ideal and Non-Ideal Theory. All of the pieces combine clarity and accessibility with a top scholar's critical and original point of view. The introductory essay briefly situates this snapshot of the state of the art in a broader view of developments in political philosophy in the last 40 years, and looks forward to future developments. Students and scholars alike will find the pieces to be valuable not only surveys but as provocations to think further about the questions, puzzles, and practical problems that animate recent work in political philosophy. The issues will be of interest to many working in philosophy, political science, law, economics, and more.
