No endeavor, such as this project, reaches completion without the input, both direct and indirect, of many supporters. I am indebted to a large number of such colleagues, friends, and family. And I am now privileged to have a platform from which to express my appreciation and my gratitude, both of which have always been felt but perhaps not completely articulated.
With regard to my colleagues, they come in two forms. The first is my professional mentors and peers through whom I have been exposed to a level of intellectal discipline, sophistication, and challenge that was, and continues to be, extraordinary. They include Drs. Francis H. Parker, Eliot Stellar, Daniel X. Freedman, Willard Gaylin, Frederick K. Goodwin, Howard F. Hunt, Shervert H. Frazier, Roger A. Mackinnon, and Robert Michels ... thoughtful teachers and superb researchers and clinicians who proved to be not only sources of seasoned knowledge but also of sage advice. A special acknowledgment to three colleagues, in particular: Dr. Leith McMurray, with whom I initiated preliminary discussions about this book many years ago, and Dr. Richard C. Friedman and Dr. Zira DeFries, stimulating and supportive friends through thick and thin.
The second group of colleagues comprises patients who provided me with the opportunity to know them and to grow with them. They must indeed be acknowledged.
I am grateful to two friends, especially, A. Joseph Lipton and
