In this compact, fluently written survey leavened with humor, New Jersey mathematics professor Bennett (Randomness) entertains as she instructs, focusing on "the barriers we face in trying to communicate logically with each other." The author covers the ancient Greeks (the Greek word logos means "knowledge"), then such giants as Leibniz and Newton, who helped rescue the study of logic from classical languages, finally modern mathematicians and philosophers like Whitehead and Russell. In discussing topics like syllogisms, she uses tables and diagrams that shouldn't daunt anyone with a firm foundation in high school algebra and geometry. The book's most interesting chapter explains why if is perhaps the most problematical word in any verbal proposition. Everyone, including the hopelessly innumerate, will find Bennett's lessons in the tricks of speech invaluable, particularly in this election year.
