John Rawls's A Theory of Justice has been widely acclaimed as a book whose influence on the discussion of central questions in moral and political philisophy will be permanent. A brief review, writes Dr. Barry, would be of little more value than would be a brief review of Hobbes's Leviathan; instead, in this book he interprets Rawls's main tenets and discusses them with appropriate thoroughness. The book is in three parts. Chapters 1-5 set Rawls's theory in its intellectual context and give an account of its basic features. Chapters 6-11 examine Rawls's claim to have advanced two principles of justice, and provided a logical deduction of them by showing that men denied various kinds of information about themselves and their society would choose them as the most rational way of advancing their conception of the good. Chapters 12-15 extend the discussion to cover the most important of Rawls's economic and political deductions. Dr. Barry's argument is that Rawls's theory of justice does not work; but that A Theory of Justice is nonetheless a work with which anyone in future who proposes to deal with any of the topics it touches must first come to terms. His critique may be read either in conjunction with A Theory of Justice (there is a concordance of passages discussed) or independently of it.
