Acknowledgments

I have had a great deal of help with the early drafts of this manuscript. A number of people have contributed mightily with voluminous notes, clarifications, and comments on passages that were unclear. You have them to thank, as much as me, that this volume is readable at all. I can't thank them enough for generously giving of their time and expertise. I have listed them in approximately the order of the substantiveness of their contributions. I don't want to diminish anyone's contributions, because every contribution improved the book, but I do want to recognize those who provided measured improvements to the work:

Joram Borenstein
Bob Smith

Mike Uschold
