Dworkin lays out two core principles that citizens should share: first, that each human life is intrinsically and equally valuable and, second, that each person has an inalienable personal responsibility for identifying and realizing value in his or her own life. He then shows what fidelity to these principles would mean for human rights, the place of religion in public life, economic justice, and the character and value of democracy. Dworkin argues that liberal conclusions flow most naturally from these principles. Properly understood, they collide with the ambitions of religious conservatives, contemporary American tax and social policy, and much of the War on Terror. But his more basic aim is to convince Americans of all political stripes--as well as citizens of other nations with similar cultures--that they can and must defend their own convictions through their own interpretations of these shared values.
