正義應該如何應用於家庭呢？歐肯挑戰羅爾斯的理論，認為他並未一致地應用正義原則於社會基本架構與家庭。本文為羅爾斯辯護，論證說明他的觀點未犯矛盾之謬。這是因為他的正義原則應用方式蘊含的是對於親人與非親人之間的差別責任空間，再者則是，他的政治正義觀提供了家庭內正義的合理守護。本文認為，羅爾斯正義原則的應用，是一項根據公民多元認同與立場差異的事實必然衍生對人的差別責任與情感，基於正義要求而安排的二元應用。歸根究柢而言，羅爾斯式家庭正義論，適足以作為我們相信公共政策應該與婦女平等同步的人所接受的政治哲學。

How should justice be applied to the family? Susan Okin challenges John Rawls for his inconsistently applying the principles of justice to the basic structure of society and the family. In this paper, I present arguments in defense of Rawls against such charge of inconsistency. Rawls’s view is not contradictory, for his way of application implies a space for different kinds of duty for people who are near and dear and not; moreover, his account of political justice offers a reasonable protection for justice within the family. That is, Rawlsian way is a dualist arrangement of justice, which is supported by the fact that citizens’ multiple identities and standpoints necessitate different duties and affections. Eventually, Rawlsian family justice could serve as political philosophy for what many of us who believe public policy should be in accordance with women’s equality.
