Eventually, I settled on these:
Thank God for Evolution, by Michael Dowd. I bought this mainly because I have seen many people refer to it or engage with it on blogs, so I thought it might be worth it to actually read it for myself . Whether or not I will ultimately agree with it, I think it will be an interesting read.
The second book The Bible, by Karen Armstrong, I bought mainly because it was only a few dollars and I have read a little bit of Armstrong before and thought spending $3.00 on an unknown book was an acceptable risk.
The third book The Bhagavad Gita, translated by Eknath Easwaran, is a part of Hindu Scripture. A blogger referred to it in one of my recent blog conversations elsewhere, in a completely non-Hindu context, and I had recently caught the tail end of an episode about it on PBS in their World Literature series. It piqued my interest.
I had weened down my pile of books to just these three. Initially I had wanted to get a paperback copy of The Koran and a book called God is Everything: The Radical Path of Non-dual Judaism; The Koran simply so that I could familiarize myself with Islam in more depth rather than depending on things that are communicated third-hand and God is Everything because one of the things that set me on the path that I have taken in the last few years was the realization that Old Testament Judaism was quite non-dualistic. I was curious to see what a modern take from a Jewish writer might look like.
Alas....I couldn't justify spending that much even though the prices were steeply discounted. I had to set some limits for myself..
I'll post on each of these once I have a chance to read through them.
