Strictly speaking, nothing is ever the product of just one worker, as explained in Chapter 9. This book owes much to too many people for me to thank them all. Those who taught me when I was a student, many years ago, deserve great credit, especially for the times when they carefully explained things that should have been obvious without an explanation. I can only hope that I had as much patience with the students I later taught during my academic career at U.C.L.A., Cornell, Rutgers, Howard and Amherst.
Among those who contributed more directly to this book by reading it in manuscript and making comments and suggestions were my wife Mary and my colleagues Professors Walter E. Williams of George Mason University and William R. Allen of U. C. L.A., as well as my friend and New York attorney James Higgins. It goes without saying that they are not to blame for any remaining errors or shortcomings of mine.
