This book contains Smullyan's famous logic puzzles about knights (who always say the truth) and knaves (who always lie) and all interesting combinations thereof. Apart from providing intellectual fixes for maths junkies, this book actually teaches logic through ...more

Beginning and ending sections include jokes about logic and logicians that teach a huge amount about logic itself. A section in the back teaches about Godel's Theorem in a simple way anyone can understand (perhaps more elegantly than Hoftadter did, perhaps not). He gives a feeling for what logic is and why we understand it the way we do.

A couple of things I noticed which would really help:

The final Part was generally very different in tone from the rest, and the description of Gödel's actual work could have done with more unpacking, I feel. So if you're after intuitive understanding of those theorems, I could not recommend this as a sole source.

*In this popular puzzle, a man has committed a crime punishable by death. He is to make a statement. If the statement is true, he is to be drowned; if the statement is false, he is to be hanged. What statement should he make to confound his executioner?*

I got this book after reading The Tao Is Silent and deciding that Mr. Raymond Smullyan must be one of my favourite people out there. A logician, a magician, a pianist, a Taoist

*and*a mathematician? (it rhymes!)

Okay - for that last part he failed since I still don't understand it. ...more

I only give it four due to the fact that it's a great tool, but it doesn't excite me or lead me to an exciting world. It's a refreshing and grounding ...more

But, seriously: If you like logic puzzles, you'll like this book for sure. Smullyan is a very funny author and all his works are permeated by his lighthearted spirit and creativity.

recommended by Scott Aaronson when I asked if there had been any investigation into why truth is such a mathematically strange concept.
