Magician and author Penn Jillette is a guest on "Piers Morgan Tonight" this evening, and he and Piers Morgan have a lively discussion about atheism and religion. "I am a huge fan of proselytizing," says Jillette. "I am a huge fan of speaking your mind. The only way we can share the universe...is by talking very strongly about what we believe."
"I never hear an atheist give me any answers," said Morgan. Responded Jillette: "Saying we can't understand it is not an answer." Watch the full interview tonight at 9pmET/PT – also on the show, Rudy Giuliani and Harvey Weinstein.
