ACKNOWLEDGMENTS

Thanks are due to Susanne Steitz-Filler, Senior Editor at Wiley, for her support of this project. Thanks are also due to Sari Friedman and Katrina Maceda, both at Wiley, for their work in producing this book. Lastly, I wish to thank the anonymous reviewer whose comments proved beneficial.

On a personal note, I would like to express my gratitude to my parents for their continued caring and support; to my brother and his wife, who will make sure my niece learns her math; to my dissertation advisor, Paul Eklof, who taught me both set theory and model theory; to Robert Meyer, who introduced me to symbol logic; to David Elfman, who taught me about logic through programming on an Apple II; and to my wife, Barb, whose love and patience supported me as I finished this book.
