Martin Gardner died around the time this book was released. Like many of his books, it compiles articles and essays that he has written over the years. This volume lacks much of the consistency of his other books. As usual, he still manages to hit some of this favorite topics: mathematics, pseudo-science, religion, and his overly-enthusiastic love of G.K. Chesterson. Personally, I think he is at his best when he is looking for paradoxes and puzzles within the framework of these broader areas of interest. That was truly his area of expertise, and when he strays from that it can feel like he is just indexing facts without much insight. Despite the lackluster quality of this book (and the fact that it ends on the sour note of his pro-socialism politics), he will be missed.
