Michael Lamb’s recent book A Commonwealth of Hope presents an opportunity for bioethicists to engage in critical self-evaluation in order to consider anew why and how to engage difficult bioethical problems and questions with those who maintain diverse moral and metaphysical perspectives. Drawing on an account of the virtue of hope from Augustine of Hippo, Lamb develops a political theory in which hope provides common ground for political cooperation between diverse citizens of a commonwealth. The purpose of this introduction is (...) to sketch out a framework by which to assess and evaluate whether bioethics demonstrates hope. This article provides a summary description of Lamb’s presentation of Augustine’s virtue of hope and his concept of politics. Then it considers implications of Lamb’s politics of hope for bioethics, identifying three features of hopeful bioethics, with which bioethicists can engage in self-reflection and evaluation. (shrink)
