This Salon article called The Atheist has been sitting in my ‘to read’ bin for weeks now, and I’m finally getting ’round to it. My god (ha ha), I love Richard Dawkins.

You delve into agnosticism in “The Ancestor’s Tale.” How does it differ from atheism?

It’s said that the only rational stance is agnosticism because you can neither prove nor disprove the existence of the supernatural creator. I find that a weak position. It is true that you can’t disprove anything but you can put a probability value on it. There’s an infinite number of things that you can’t disprove: unicorns, werewolves, and teapots in orbit around Mars. But we don’t pay any heed to them unless there is some positive reason to think that they do exist.

Believing in God is like believing in a teapot orbiting Mars?

Yes.
