- If one reads through philosophy, one will find many attempts at mathematical
- proofs of God's existence. All these 'ontological proofs' have very obvious
- and silly errors. It is quite clear that mathematics is not capable of making
- a statement on the ontological status of God. Sure, maths can make lots of
- comments about the hyperbolic plane, the Zariski Topology, the lattice of r.e
- sets and so forth. But God? No way!
- Asides from limitations in the expressive power of mathematics, the following
- will show any proof of the ontic status of God futile.
- 1. It is possible to imagine a world, completely agreeing with the current one
- on all sensory data, in which God exists.
- 2. It is possible to imagine a world, completely agreeing with the current one
- on all sensory data, in which God doesn't exists.
- Call a world satisfying condition 1 M, and a world satisfying 2 M'.
- Then the existence of these epistemically indistinguishable worlds proves that
- any ontological statement about God is INDEPENDENT of any epistemically
- knowable axioms on the real world. So no proof either way exists. Bravo.
- Notes 1. Some people say world M' is impossible, because the beauty of the
- world we live in necessarily entails God's existence. There are many similar
- arguments, basically content isomorphic to this. In fact, this argument is
- content isomorphic to the trivial or empty argument, so not much need be said.
- I assume my response to such a person is implicitly made clear in the previous
- comments.
- 2. It will strike many as odd that even Godel believed he had a proof, using
- modal logic. If you can bother spending the time reading it (it is quite
- complex), I'm sure you'll spot the error. It's more sublte than most other
- ontological errors, but it's there, unavoidable, and unrectifiable. I suppose
- even great mathematicians can go loony every now and again.
- Well, there you have it. No further comment necessary.
