關於正當與善的優先性，爭論已久，社群主義的代表人物之一沈岱爾對於羅爾斯在《正義論》中強調正當的優先性非常不滿，他以《自由主義與正義的局限》一書對羅爾斯的觀點提出批評。本文打算從「正當是否優先於善」這個議題來討論這兩位學者相互對話辯論的過程，並提出作者個人的看法。

　　　　　The long debate between M. J. Sandel, the leading thinker of Communitarianism, and John Rawls centered on the question of priority between right and good. Sandel was strongly dissatisfied with Rawls's view on the priority of right in 'A theory of Justice', and expressed his criticism in his book 'Liberalism and the Limit of Justice'. This paper intends to investigate the debate of these two thinkers using the theme of "Weather the right is prior to the good" as a way of approach, then to formulate some personal points of view on this subject.
