Abstract

In recent years an increasing number of moral theorists have come to embrace the term "moral pluralism" to describe a particular kind of moral theory. Unfortunately, there has been little consensus regarding what exactly constitutes a pluralistic theory, and what specific commitments such theories involve. My dissertation takes on the task of articulating the underlying schema of pluralist moral theory, and of analyzing the plausibility and implications of pluralism's fundamental commitments. I argue that the most thoroughgoing pluralist theories are shaped by two defining theses; the plurality of the good , and the plurality of the right , and that these are conceptually linked by two additional meta-ethical commitments. My analysis of the plausibility of these commitments is at times friendly to moral pluralism and at times critical of it. For instance, I develop an account of "value incommensurability," an idea upon which pluralism depends, that resists some of more the important attacks within the literature. Yet I also criticize the commitment to the plurality of the right, as held by Susan Wolf and several other pluralists. I argue that this view is less plausible than "limited pluralism"---a view that is pluralistic about the good but monistic about the right. In the final chapter I explore the relationship between moral pluralism and political liberalism, focusing on the role that overriding values play within each type of theory
