Samuel Freeman was editor of Rawls's Collected papers and is thoroughly familiar with his work. What makes this book great and important is that it is extremely well written book on seminal thinker that explains all the important facets of his philosophy. An excellent explanation of Rawls's complex theories of justice and political liberalism that concludes with chapter on The Law of peoples. Rawls's complex ideas are presented with great clarity and grace and although there are 550 pages the text does not get bogged down in unimportant details. This book will be the central reference for serious study of Rawls.
This is a extremely good book. Freeman shows himself a try expert in Rawls's work. If you want to read Rawls's books. I suggest you to read this book along with this. Substaintial parts of the book are adressing Rawls's books Theory Of Justice and Political Liberalism. But also alot of essays, shorer books and the relation between all of this is not forgotten. It really helped me to understand Rawl's theory, thoughts and ideas. Alot and alot better that what I read in Kymlicka's Contemporay Political Philosophy.
Apart from an explenation on Rawls's theory Freeman also is duscussing several of Rawls's critics.
So all in all a invaluable book to those who wish to understand one of the greatest political philosophers of all time.
One remark. The book is not 416 pages as stating here but more close to 575, or atleast mine is.
