Abstract

What are the principles of association that citizens devoted to different ethical and religious ideals or peoples living under different regimes can find reason to acknowledge together? Defining the common ground which reasonable people can share, despite their profound disagreements, has been the distinctive concern of John Rawls’ political philosophy since A Theory of Justice. Rawls’ second book, Political Liberalism, recast his theory of justice as fairness in a form no longer tied to a Kantian view of the moral life as a whole. “Political liberalism” revolves around the idea of “public reason”, the shared point of view which free and equal citizens assume when, abstracting from their opposing comprehensive doctrines, they decide constitutional essentials and matters of basic justice in the light of a principle of reciprocity. “The Idea of Public Reason Revisited,” originally published in 1997, forms the second part of the present volume. This essay offers perhaps Rawls’ final statement of his ideal of a just society. Yet its role in this book is to provide the background for an account of the just coexistence of diverse societies. “The Law of Peoples” was the title of the Oxford Amnesty Lecture that Rawls delivered in 1993. Refined and expanded, the theory he then proposed is given here its first full-scale exposition, and my remarks focus on this part of his book.
