I began this book during my tenure as a fellow at the Center for Advanced Study in the Behavioral Sciences at Stanford, an ideal place to work. My time there was in part made possible by a grant from the Ford Foundation and the understanding helpfulness of Marshall Robinson and William Pendleton at the foundation. I have also had the aid of the William W. Cook Fund at the University of Michigan Law School.

I am grateful to friends and colleagues, who read my manuscript and provided critical suggestions: Phil Soper, Fred Small, Elli Sax, Terry Sandalow, Don Regan, Spense Havlick, and Lee Bollinger.
