"...all three of the essays are quite well written, and the authors expound their positions with admirable vigor and clarity. This work will certainly be of significant interest to anyone concerned with the Hohfeldian jural framework, the 'Interest' and 'Will' theories of rights, or the rival analytic and evaluative approaches to the philosophical foundations of rights theory. It is, then, a more than welcome addition to our ongoing 'debate over rights'."--The Law and Politics Book Review
