Abstract

This essay considers the relationship between ideal theory and non-ideal theory. It begins with Rawls’s conception of ideal theory and A. John Simmons’s articulation of non-ideal theory. Both defend the priority of ideal theory over non-ideal theory. The essay then considers three different conceptions of the social barriers standing in the way of an ideal society, taken broadly from Mill, Marx, and Foucault. Each conception of power suggests a divergent strategy for pursuing non-ideal theory. The Foucauldian conception also suggests reasons to mistrust our own political and moral judgments. The essay advocates a more limited view of the relationship between ideal and non-ideal theory than is commonly described, in which ideal theory retains its logical priority but not its temporal priority. In other words, the essay argues that we will fare best when we focus first on reducing specific injustices while setting aside further speculation about the character of an ideal society
