Stretch your logic muscles here
2000/11/23
By Charles Ashbacher
- (Amazon.com)
形式:ハードカバー
He is "simply the best" is the phrase that most accurately describes the ability of Raymond Smullyan to create puzzles in logic. Written at a lower level than some of his other books, no background in formal logic is necessary to understand and solve all of the problems in this collection.
While the novice will find the problems understandable, even the veteran will experience new levels of logic consciousness as they twist their way through to the solutions. As the name implies, all of the problems in some way involve characters created by Lewis Carroll, and solutions to all are given at the end of the book.
If you wish to have your intellectual muscles worked and smile while it is done, then this book is for you.

This time the reader comes along for Alice's adventures in Wonderland as a logical analysis, to asses the logical understanding and thoughtfulness of the inhabitant's minds (rendering surprising results). The puzzles go first from a young child's birthday party, then onto the mysteries of the eateries in the Queen's Kitchen. Next, Alice decides from obscure facts and hints who is mad in Wonderland (waddya go Alice!). Next tackle some clever algebric and arithmetic problems of the two queens and Griffon...just don't use algebra and arithmetic! Then help the White King decipher who the devil was the spy in his various trials. Travel through the woods to play some interesting card games with the Tweedles. Then kick back as Humpty Dumpty, with his little desire for brain cells, gives a 'true logician's' lecture on the nature of paradoxes and Godel's Incompleteness Theorm. At long last wrestle with some truly difficult puzzles in which the abscent-minded White Knight has almost completely forgotten the facts of some very interesting trials. Then asses the nature of a Looking-Glass logician. And finally analyse one of life's deepest mysteries...dreams. Did the Red King actually hit on the mark with his propositions of Type A and Type B? Or was he perhaps just a figment of Alice's imagination? But then...well, I'll let you decide. At any rate...read this book!

Best of the best

Raymond Smullyan is one of the best writers of logic puzzles, and this is perhaps his best book. It is suitable for young readers - there are puzzles in Chapters 4 and 12 specifically for people who have not learned (or do not remember) algebra - but it also contains many puzzles challenging to an adult reader. And throughout, there is surreal humor worthy of Lewis Carroll himself.
Most of the book focuses on variations of "liars and truthtellers" puzzles. Alice has to determine who stole the tarts, who is mad, who is the spy, and whether Tweedledum or Tweedledee has a black card. Things really get interesting in Chapter 5, when Alice is presented with some meta-puzzles. These are puzzles that leave out a crucial piece of information, but tell you that if you had that information, you'd be able to solve the puzzle. Oddly enough, once you know that the puzzle would be solvable, you can actually determine the solution!
There is a chapter on paradoxes (and classic puzzles generally thought to be paradoxes but aren't) and a chapter on "looking-glass logic", in which Alice is presented with a series of conditions, and asked to deduce the logical conclusion.
Smullyan stays true to his Carrollian inspiration throughout the book. We meet all the classic characters from the Queen of Hearts to the White Knight, who all devise new ways to confuse and torment poor Alice. This book gets high marks for originality, entertainment, and for presenting some intriguing and highly challenging puzzles.
