"What does citizenship have to do with living a worthy human life? Political scientists and philosophers who study the practice of citizenship, including Rawlsian liberals and Niebuhrian realists, have tended to either relegate this question to the private realm or insist that ethical principles must be silenced or seriously compromised in our deliberations as citizens. This book argues that the insulation of public life from the ethical standpoint puts in jeopardy not only our integrity as persons but also the legitimacy and long-term survival of our political communities. In response to this predicament, David Thunder aims to rehabilitate the ethical standpoint in political philosophy, by defending the legitimacy and importance of giving full play to our deepest ethical commitments in our civic roles and developing a set of guidelines for citizens who wish to enact their civic roles with integrity. In this way, this book provokes a lively conversation about the ethical foundations of public life in constitutional democracies"--
