"The best of American legal theory has attempted to explain and justify an approach focusing on the features of individual cases and avoiding reliance on rigid rules. Sunstein's book not only offers the most comprehensive attempt to defend particularistic decision-making in all of its manifestations, but also gives the most powerful defense. Defenders of rules, categories, and abstraction will have a formidable task in trying to penetrate the armor of Sunstein's normative defense of particularistic decision-making." Frederick Schauer, David and Mary Harrison Distinguished Professor of Law, University of Virginia School of Law "

"Cass Sunstein's book makes a significant addition to our understanding of how the law works and of the nature of law itself. He explains in lucid prose, with many concrete examples, the components of good (and bad) legal reasoning and how they contribute to the outcome of legal controversies. Sunstein's ideas, which combine keen insight, common sense, and a vast knowledge of legal materials, are sure to prompt discussion....The book will be of great value to scholars as well as to those who are beginning the study of law." Lloyd L. Weinreb, Dane Professor of Law, Emeritus, Harvard University Law School "

"[Sunstein's] carefully nuanced description of the kind of reasoning employed in law, a process often mysterious to outsiders, is the best I've seen, and captures the way judges actually make decisions in most cases....Professor Sunstein has provided an articulate and comprehensible entry into the intellectual world of lawyers and judges.... Anyone who wishes to learn what 'thinking like a lawyer' is all about should read this book." The New York Times Book Review "
