Most foundational works in political philosophy have made fundamentally false and far-reaching assumptions concerning the culturally homogeneous character of the polity.Deliberative Democracy, Political Legitimacy, andSelf-Determination in Multicultural Societies provides a much needed corrective to conventional accounts of the normative foundations of the state by reconceptualizing some of the fundamental issues in political theory from a perspective that recognizes the culturally pluralistic character of contemporary democracies. Among the issues considered are democratic deliberation in multicultural societies, the justification and function of political communities, the nature of self-determination, the justification of cultural rights, and the moral rationale for regional self-governance and secession. This work is suitable for graduate and upper-division undergraduate courses in political philosophy and political science, as well as the lay reader interested in understanding the major sources of conflict and instability in democratic societies.
