The list author says: "People sometimes wrongly assume "Atheist" is merely a refutation of God (which technically, it is) - but behind that are usually a hoard of well formed ideas, based on research, facts and understanding. Atheists are more likely well-read, intelligent and informed than those who are content with their faith and not seeking answers. The "Atheist" or Freethought Discourse is usually not much about God at all, but about the impact and value of religion in human society. Often, spiritual seekers who need a nobler and more ethical Truth than the one offered by religion find themselves labelled Atheist simply because of their refusal to condone or ignore the harmful effects of organized faith.
At any rate, these are a few good books which may be useful for those interested in the complicated but enthralling topics of the impact of religion on culture, the history of modern world religions, and the alternatives to deism."
