Whether we should obey the law is a question that affects everyone's day-to-day life, from traffic laws to taxes. Most people obey out of habit, but the question remains: why are we morally required to do so? If we fail to obey, the state may enforce compliance, but is it right for it to do this, and if so, why? In this book, George Klosko, a renowned authority on political obligation, skillfully probes these questions.  He considers various prominent theories of obligation and shows why they are unconvincing, contending that only an approach that interweaves multiple principles, rooted in "fair play," is fully persuasive. Klosko develops the fullest statement of his own well-known theory of political obligation while providing a clear overview of the subject.  The result is both an essential introductory text for students of political theory and philosophy and a cutting-edge, original contribution to the debate.
