See the first few paragraphs in the section, “Atheism is Preposterous.” By “atheism” I include what atheism practically entails, namely a naturalistic, nontheistic account of the something, as opposed to the someone, that must be the ultimate cause of everything else in nature.

If you’re thinking of someone who has no such positive view to go along with atheism as the denial of theism, you’re thinking of an agnostic or skeptic who isn’t even committed to physics or cosmology. Most atheists are committed, instead, to philosophical naturalism and to the consensus views in all of the sciences, which amount to the positive side of their worldview.

The question, then, is whether that positive side of most atheists’ worldview has a religious or nonrational aspect.
