Mathematics and Religion
A mathematician is asked by a friend who is a devout Christian: "Do you believe in one God?"
He answers: "Yes - up to isomorphism."
If a religion is defined to be a system of ideas that contains unprovable statements, then Godel taught us that mathematics is not only a religion, it is the only religion that can prove itself to be one. -- John Barrow
God exists since mathematics is consistent, and the devil exists since its
consistency cannot be proved.
-- Hermann Wey
