The past three decades have witnessed the emergence of several Kantian theories. Both the critical reaction to consequentialism inspired by Rawlsian constructivism and the universalism of more recent theories informed by Habermasian discourse ethics trace their main sources of inspiration back to Kant's writings.

This excellent volume is a welcome and quite distinctive addition to political philosophy generally as well as to our understanding of Kant and Kantian approaches to political problems. The book's thirteen essays, including a substantive editor's introduction, collectively serve to probe the importance of metaphysics for grounding political principles and applying those principles to concrete political and moral issues in the contemporary context of pluralism and diversity. - Mark Timmons, University of Arizona
