The course will explore a number of contemporary debates about the nature, scope, and requirements of justice. Is justice an objective standard accessible to reason, or is it, in some sense, the product of human choice? Do we have obligations of justice to all human beings, or only to our fellow citizens? Which, if any, facts about individuals are "arbitrary from a moral point of view"? In order to pursue justice in the real world, do we need a theory of justice? If so, what issues would the theory have to resolve?
