This article describes the influence of under-acknowledged assumptions about property rights, akin to those more frequently associated with John Rawls' foremost libertarian critic, Robert Nozick, on the debate concerning liberty and equality. It shows that Nozick's challenge to egalitarians has played an important role in Ronald Dworkin's alternative statement of liberal egalitarianism and indirectly influenced later non-Rawlsian egalitarianisms. The article also discusses Rawls's initial formulation of the so-called luck-sharing project.
