Justice in Ideal Theory: A Refutation

In this article I argue that theorizing about justice at the level of ideal theory is inherently flawed and thus has impoverished liberal egalitarianism. Ideal theorists (falsely) assume that a political philosopher can easily determine (or has privileged access to) what constitutes the ‘best foreseeable conditions’. Furthermore, by assuming full compliance, ideal theorists violate the constraints of a realistic utopia. More specifically I argue that liberal egalitarians who function at the level of ideal theory adopt a cost‐blind approach to rights and a narrow view of possible human misfortune. The former issue leads liberal egalitarians to give priority to a serially ordered principle of equal basic liberties or to treat rights as ‘trumps’; and the latter to a stringent prioritarian principle (Rawls' difference principle) or luck egalitarianism. Taken together, the cost‐blind approach to rights, coupled with the narrow view of human misfortune, mean the liberal egalitarian theories of justice cannot address the issue of trade‐offs that inevitably arises in real non‐ideal societies that face the fact of scarcity. This makes liberal egalitarianism an ineffective theory of social justice.
