Relating bioethics to the philosophy of the city creates the possibility for developing the field along paths not yet explored. In the Western tradition, the city has been understood as the venue for two quite different forms of activity and two different types of moral possibility. In one guise, the city is an urbs, a center of commerce, market exchange, and social individualism. In another guise, the city is a civitas or polis, the space of active democratic citizenship, equality under law, and civic virtue. As civitas, classical philosophers regarded the city as the place of moral growth and full human self-realization. These two possibilities of human moral and political experience in the city have given rise to distinct traditions of political theory--liberalism and civic republican and democratic theory. This article traces these conceptual configurations into the domain of contemporary bioethics, arguing that most work in the field has drawn on the liberal tradition and hence has been insufficiently critical of the moral paradigm of market individualism and unduly inattentive to the values of civitas and the civic tradition. It argues for the creation of a form of civic bioethics and explores some of the theoretical foundations that type of bioethics would require.
