It is my custom on Thanksgiving Day to give thanks to one of the many teachers and scholars who played an important role in my development as a teacher and scholar. Early in my career, a number of prominent scholars kindly provided comments on the first article that I published after graduating from law school, On the Indeterminacy Crisis: Critiquing Critical Dogma, 54 University of Chicago Law Review 462 (1987). At the time, I really did understand the extraordinary level of generosity that these comments represented. Fred Schauer, who was then at the University of Michigan and is now at the University of Virginia, and Ronald Dworkin, who was then primarily at Oxford and NYU, both provided extensive comments. Their feedback provided invaluable encouragement for a young and unknown scholar. Both Schauer and Dworkin influenced my work in other ways. Fred Schauer's book, Free Speech: A Philosophical Enquiry, had a profound influence on my second article, Freedom of Communicative Action, and served as a model for careful and deep work on the connections between moral and political philosophy and normative legal theory. I had read Ronald Dworkin's Hard Cases as an undergraduate, and his most important monograph, Law's Empire, came out towards the end of my first year of law school teaching. Both had a profound influence on my thinking about the law, and I thought of myself as a Dworkinian during my early years as a legal scholar. Thank you Fred Schauer and Ronald Dworkin.
