This book examines a number of different accounts developed by philosophers and political theorists to explain why political disagreement is so extensive and persistent. The author argues that moral and political questions can have correct answers, but that not every reasonable person will necessarily be satisfied with these answers. He develops a framework that gives a role to the individual's reasons for his or her beliefs, but also to psychological and sociological factors, to explain the intractability of political disputes.
"The arguments developed by Mason are important contributions to an ongoing conversation about political disagreement. Adding to the agenda of distinctions and criteria will be a normal reaction from readers forced to think about these problems at a different level. No higher tribute can be paid to a book." Fred M. Frohock, American Political Science Review "...clear and persuasive...a very good and well-written book." Ethics
