 On her view, the social bases of self-respect require the robust anti-discrimination principle that FEO provides. In defense of Rawls on the second objection, Robert Taylor (2004) has attempted to show that self-realization has a crucial place in the hierarchy of goods on the Kantian interpretation of Rawls’ principles. He claims that FEO therefore has priority over the difference principle because it regulates goods that are more central to the exercise of our moral powers and our highest order interests. However, his defense of Rawls has been criticized for being overly perfectionist and therefore not politically liberal. If this criticism is sound, then it may seem to imply that while perfectionist Rawlsians can justify FEO, political liberal Rawlsians cannot. Liam Shields (2015) argues that there is a non-perfectionist account of self-realization and that this leads us to supplement the principle of FEO with a principle of sufficient self-realization. This may be one way to defend FEO against those who favor a strict focus on welfare.
