That's an awesome suggestion.
When I read Chapter 4, We Agnostics... and consider that it was written by a sober alcoholic with less than three and a half years sobriety... that had trouble all his life with any kind of "God idea"... it makes me wonder how he could have written such a profound spiritually oriented masterpiece of literature. The Chapter could be individually bound as a separate book -- and stacked up to match the quality and depth of any spiritual book that I have ever read. It's one of those chapters of a book that keeps on giving.
For anyone that has trouble believing in Intelligent and Invisible Powers greater than their self... I suggest getting a couple of magnets and spend an afternoon playing with them. (Or... stick your finger in a light socket and turn the switch on... to see what an Intelligent Invisible Power feels like! But, remember -- it won't work if you only think about it and don't work it!)
Or, get one of those remote GPS gadgets... and play with that for a while. And, explore the idea of where the Intelligence came from that could organize natural laws and physics... to make it possible for the gadget to work.
Or... consider the facts that math was not invented.... it was something that had been around longer than the history of man... and it was discovered by man... rather than invented by him.
Perhaps we have only scratched the surface of the things not seen -- that are still waiting for discovery.
