Ronald Dworkin is widely accepted as the most important and most controversial Anglo-American jurist of the past forty years. And this same-named volume on his work has become a minor classic in the field, offering the most complete analysis and integration of Dworkin's work to date. This third edition offers a substantial revision of earlier texts and, most importantly, incorporates discussion of Dworkin's recent masterwork Justice for Hedgehogs . Accessibly written for a wide readership, this book captures the complexity and depth of thought of Ronald Dworkin. Displaying a long-standing commitment to Dworkin's work, Stephen Guest clearly highlights the scholar's key theories to illustrate a guiding principle over the course of Dworkin's work: that there are right answers to questions of moral value. In assessing this principle, Guest also expands his analysis of contemporary critiques of Dworkin. The third edition includes an updated and complete bibliography of Dworkin's work.
