Attlee: I'm one of those people who are incapable of religious feeling.
Harris: Do you mean you have no feeling about Christianity, or that you have no feeling about God, Christ, and life after death?
Attlee: Believe in the ethics of Christianity. Can't believe in the mumbo jumbo.
Harris: Would you say you are in agnostic?
Attlee: I don't know.
Harris: Is there an after-life, do you think?
Attlee: Possibly.
