Many people have helped me write this book. Among them are a number of student research assistants who guided me to useful readings in the various fields of policy I wanted to discuss. All of them gave valuable assistance, but three deserve special mention. Andrew Nicol pre- pared an exceptionally valuable set of readings in philosophy. Chris Robert shared with me his firsthand experience observing the work of the government of Bhutan in implementing its offi- cial goal of increasing Gross National Happiness. Jason Marisam displayed a remarkable ability to survey a wide variety of policy issues and immediately produce an analysis filled with issues to explore and policy options to consider.
Other friends and colleagues kindly read individual chapters and gave me useful comments. Among these valuable critics were Mary Jo Bane, Dick Easterlin, Dan Gilbert, David King, John Helliwell, Steve Hyman, Michael McPherson, Mark Moore, David Nathan, Theda Skocpol, Julie Wilson, and Dick Zeckhauser. James Shul- man and Elena Zinchenko were kind enough to read the entire manuscript and offer helpful suggestions, as did the three anony- mous readers selected by the Princeton University Press. Kim Has- tings also earned my gratitude for an outstanding copyediting job that significantly improved the final manuscript.
In addition, I owe particular thanks to Connie Higgins, who brought me countless books and articles and prepared more drafts and revisions of drafts than she or I could possibly remember.
