Many people and institutions have helped me bring this book to publication. The University of Chicago's Donnelley Exchange Scholarship allowed me to spend a year studying Locke at Cambridge University the year after I graduated. Cambridge was the best possible place for me to pursue my interest in Locke. The M. Phil. Program in Political Thought and Intellectual History provided enormous flexibility and allowed me to research and write my thesis on Locke's theory of natural law, a theme that figures prominently in the present work. Although the present work is less historical in its focus, it is still shaped by the work that I did at Cambridge. Richard Tuck served as my primary advisor that year, and John Dunn provided considerable help as well. Even after I left Cambridge both have been willing to take the time to discuss my current research and provide helpful suggestions. It was also at Cambridge that I met John Michael Parrish, another student in the same program, who has been an invaluable friend and colleague ever since. He has read and commented on several drafts of the present work.
This book is a substantially revised version of the Ph.D. dissertation I wrote at Princeton University. Both in the people who were there and in the resources that were available, Princeton was an ideal location for my project. Support from the Politics Department, the University Center for Human Values, and a University Honorific Fellowship allowed me to devote most of my time to research and to finish much more quickly than would otherwise have been possible. While I was a student there I also received a generous grant from the Harvey Fellows Program that allowed me to go to Oxford for one month to read in the Locke archives at the Bodleian Library. I owe a debt of thanks as well to the faculty and to my fellow graduate students at Princeton who made it a vibrant political theory community: Oliver Avens, Paul Bou-Habib, Aurelian Craitu, Patrick Deneen, Suzanne Dovi, Denise Dutton, Stephen Holmes, George Kateb, David Korfhage, Jacob Levy, Brenda Lyshaug, Paul Safier, Jason Scorza, Roy Tsao, and Maurizio Viroli. Posthumous thanks go to Moshe Levy, whose untimely death was a cause of great sadness for us all.
Special thanks go to the members of my dissertation committee. Robert George and Paul Sigmund gave trenchant criticisms and helpful suggestions for revisions. I owe a special debt to Jeremy Waldron, who was actively involved in advising me on the dissertation from its inception. His comments on my work, together with his own insights into Locke, law, and legislation, have left a definite imprint on my own
