I love reading almost anything that Martin Gardner wrote. His thinking is clear and logical, sensitive and nuanced. Mostly I have read his writings on mathematics and puzzles, though I also really enjoyed his book of essays The Night Is Large. Unfortunately, this book is not in the same league.
The problem is that he writes in this book about his religious views. These essays suffer in comparison with his other writing — they don’t convince at all. They are variations on the same theme: “I believe in God because — well, I just do.” It gives a good insight into Gardner’s psyche, but I am more interested in what he can tell me about the world than about himself. I think I’d rather re-read The Night Is Large.
