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.
