- I think this one is due to Smullyan:
-
- Consider the sentence "If this sentence is true then God exists"
-
- Proof: 1. The sentence is true Hypothesis
- 2. If this sentence is true then God exists From 1
- 3. God exists Modus Ponens 1,2
-
- 4. If this sentence is true then God exists Deduction Theorem 1,3
-
- The sentence is proved (and therefore true) QED
-
- Corollary: By the theorem and the fact that it is true and Modus Ponens,
- God exists.
-
- OR, of course, by a similar argument, God doesn't exist or My aunty's a banana
- or anything you like.
