ACKNOWLEDGMENTS I would like to acknowledge my debt to Irving M. Copi's Introduction to Logic, to master puzzlemaker Henry Ernest Dudeney, to Martin Gardner, and to Fred. Schuh. The following looked over the manuscript and offered suggestions: mathematician and puzzle-enthusiast Dr. David Greenwald; Dr. Arnold Scheiman of Park West High School; Dr. Ira Ewen, Director of Thinking Skills of the New York City Public Schools; and Edith Novod, Arline Beitler, Stanley Beitler, Jonathan Mandell, and Horace Mandell. The book would never have been written without the encouragement and editorial guidance of my editor at Sterling, Sheila Barry.
