The Unwritten Theory of Justice

Rawls's theory of justice has had two parallel lives in political theory. The first is framed as an alternative to utilitarianism, and in particular utilitarianism's failure to take seriously the separateness of persons and each individual's right to pursue his or her own projects in life. The second is framed as an alternative to libertarianism, and in particular libertarianism's failure to take seriously our moral obligations to the well-being of our fellow citizens. This chapter explores where and why Rawls's “justice as fairness” and libertarianism come apart. It focuses on their respective treatments of the just distribution of wealth. Finally, in the real world one would have to worry about the strains of commitment not just for those who want to defect from “justice as fairness” once they see how things turn out for them, but also from those who never accept its normative vision.
