WHATEVER the failings of this book, they would have been far greater with/ out the kind help of friends and colleagues. That this book bears little resemblance to the first paper I wrote on the subject over a decade ago is a tribute to the richness of the intellectual encounters I have had along the way. Joe Barnes, Robert Gilpin, Peter Katzenstein, Andrew Moravcsik, Nicholas Onuf, and Jack Synder read the penultimate draft of the manu/ script and provided invaluable comments. I am particularly indebted to David Lake and Michael Mastanduno for their lucid commentary on multi/ ple drafts of the manuscript. I also acknowledge Tom Callaghy, Judith Goldstein, Joseph Grieco, Charles Kupchan, John Hall, Joseph Lepgold, Daniel Lindsay, Charles Lipson, Michael O'Hanlon, John Rohr, Duncan Snidal, and Rob Sprinkle for helpful suggestions on earlier chapters and papers. I am also indebted to Daniel Deudney for stimulating my thinking through collaborative writing and a jointly taught research seminar at the University of Pennsylvania on “The Logic of the West.” I have also been helped by talented research assistants, including Thomas Sisk and Peter Funke.
The book has also benefited, fittingly, from institutional support. The Woodrow Wilson International Center for Scholars in Washington, D.C, where I was a fellow during 1998–1999, provided research support and a congenial setting needed to revise the manuscript. I am also pleased to acknowledge the financial assistance of the University Research Institute and the Christopher H. Browne Center of International Politics at the University of Pennsylvania. I am also grateful to the Council on Foreign Relations and the Hitachi Foundation for an International Affairs Fellow/ ship during 1997–1998. I thank the Brookings Institution and its Director of Foreign Policy Studies, Richard Haass, for inviting me to be a Visiting Scholar during Spring 1997. I am also indebted to Malcolm Litchfield and Chuck Myers at Princeton University Press for taking an interest in my project and shepherding the manuscript to completion, and to Margaret Case for excellent copyediting.
My greatest debts are personal. This book is dedicated to my wife, Lidia, and our two children. Work on the book manuscript began in earnest about the time of the birth of Tessa in 1995 and, in an extraordinary confluence of events, it was completed within a week of the birth of Jackson and the sad passing of Tessa in 1999. The joy and anguish of these life passages have put into perspective the struggles and pleasures of writing this book. So I am most grateful to Lidia, whose unflagging support and wise counsel made this book possible.
