John Rawls (born 1921) is one of the most important political philosophers of the 20th century. It is commonly observed that the publication in 1971 of his treatise A Theory of Justice initiated a return to political questions among Anglo-American philosophers and is largely responsible for the vigorous health of contemporary political philosophy. Rawls’s ideas and approach have transformed philosophical inquiry in this area, and political theorists are obliged to make clear where they stand in relation to Rawls if they wish to be involved in mainstream discussions. Yet Rawls’s influence has also extended beyond philosophy and has had a substantial impact on work in law, economics and political science. Since the publication of A Theory of Justice Rawls has written two other major works - Political Liberalism (1993) and The Law of Peoples (1999) - and also issued a collection of his essays, Collected Papers (1999). This four-volume, major-work collection provides a thorough analysis of Rawls’s work. In addition to a general introduction, the set includes introductions to each volume which help guide the reader through the material.
