Brief it is, but still manages to be a thorough and extensive history and discussion of liberty and freedom. Convassing many different conceptions of liberty, it is not a polemic or didactic work. It is thoughtful and well-researched. The authors deal with interesting questions and problems that arise within the history of freedom, including some of the contemporary social psych literature that is sometimes cast as providing a basis to reject the claims of classical liberalism. I hope my students find it as useful and as interesting as I did.
