In The Principle of Fairness and Political Obligation, George Klosko presents the first book-length treatment of political obligation grounded in the premises of liberal political theory. In this now-classic work, he clearly and systematically formulates what others thought impossible-a principle of fairness that specifies a set of conditions which grounds existing political obligations and bridges the gap between the abstract accounts of political principles and the actual beliefs of political actors. Brought up-to-date with a new introduction, this new edition will be of great interest to all interested in political thought.
