<p>This book originated as lectures for a course on political philosophy that Rawls taught regularly at Harvard in the 1980s. In time the lectures became a restatement of his theory of justice as fairness, revised in light of his more recent papers and his treatise <i>Political Liberalism</i> (1993). As Rawls writes in the preface, the restatement presents "in one place an account of justice as fairness as I now see it, drawing on all [my previous] works." He offers a broad overview of his main lines of thought and also explores specific issues never before addressed in any of his writings.</p><P>Rawls is well aware that since the publication of <i>A Theory of Justice</i> in 1971, American society has moved farther away from the idea of justice as fairness. Yet his ideas retain their power and relevance to debates in a pluralistic society about the meaning and theoretical viability of liberalism. This book demonstrates that moral clarity can be achieved even when a collective commitment to justice is uncertain.</p>
