I would like to thank all those who have helped with this book. For the very idea of the book, and for the ideas in it, I am most indebted to James Stromberg, who first set me on the path of understanding the truth of the natural law. He also generously read the entire manuscript and provided helpful insights. Others who supplied needed comments include Peter Koritansky, Stephen Brock, and an anonymous reviewer. Still others have helped through careful reading and correction, most especially my wife, Christine, whose loving support has sustained me through all of my endeavors. The beautiful cover I owe to Barbara Stirling, who first suggested the artwork, and to Rebecca Schreiber at Kachergis Book Design, whose keen artistic sense provided the balance and harmony for the striking design. Finally, I would like to thank all those at the Catholic University of America Press who have brought this project to realization, especially Jim Kruggel, Trevor Lipscombe, Theresa Walker, and Brian Roach.
