Dear Bill,
I hope that you are well.
Your post on a bad reason for thinking atheism is not a religion was excellent. I'm taking the liberty of sending a link to a review of mine that argues along the same lines as you do: Atheism, Ayn Rand, and Other Heresies. By George H. Smith. Buffalo, N.Y.: Prometheus, 1991. 324 pp.
Best wishes,
David
It would be intolerably self-serving of me to say that great minds think alike, so I'll just say that sincere truth-seekers sometimes converge in their views. One thing I learned from Dr. Gordon's review is that George H. Smith is the (contemporary) source of the idea that atheism ought to be defined, not as the denial of the existence of God, but as mere lack of God-belief.
