Summary: Great Book
Review: A true delight to read, although the one reviewers comments (John Morrison from Houston) brought to mind the truth of Pope's comment,"A little learning is a dangerous thing; Drink deep, or taste not the Pierian spring: There shallow draughts intoxicate the brain, And drinking largely sobers us again." As you read this book hopefully your brain will be stimulated to ask questions AND to dig deeper to learn ther answers. Smullyan is NOT wrong when he says that a false hypothesis yields a true conditional statement. I haven't read the book in decades, so I can't comment on whether or not Smullyan explicits says this, but conditional statements do not express causal relations (I can understand how a physicist would think this.)
Anyhow, this is a great book for young children with inquisitive minds and even for old children who think they know it all.MB

Summary: A must have book of logic puzzles
Review: An amazing book that trains you to use your brain effectively through a careful structure that increases in complexity as you progress. I read it when very young and would like to get copies for all my staff as it is an excellent tutorial on logic and perfect for orienting systems programmers into looking at complex problems with a fresh viewpoint. Sadly it appears to be out of print and I join the cry in asking the publisher to pull it out of the archives.

Summary: A Fantastic Logic Puzzle Book
Review: Raymond Smullyan has created an incredible set of stories designed to help the logically challenged enjoy his kind of intellectual pursuit. Each of the stories becomes progressively more entangled and continuously more engrossing. From tales of knights and knaves, to the final question, Smullyan knows how to challenge logical thought processes while engaging the imagination. If you want to expand your brain, or just want to stump and stymie your friends, then you must read this book.

Summary: A Wonderful Introduction to Logic
Review: This book is a chockful of puzzles and riddles, humorous and bizarre. The author (Raymond Smullyan) uses these puzzles to introduce formal logic in a particularly fun and interesting way. This book also illustrates the unique sense of humor many mathematicians. He characterizes a drunken mathematician as one who says, "I can prove anyshing!"
