The Riddle of Scheherazade: And Other Amazing Puzzles - Raymond M. Smullyan

A book of puzzles - some trivial , some old chestnuts and some using coercive logic. Some paradoxes, some meta puzzles in other words a mixed bag. Its quite hard to wrap your mind around some of the coercive logic puzzles and the paradoxes. A decent read but I would have enjoyed it when I was younger.
