- Hmm. I think Penrose is right about (1) but wrong about (3). I wonder
- how he persuaded you. His "proof" is based on a belief that humans are
- capable of doing things ruled out by the Goedel result. I would say it
- is this this belief which is more in the category of having a stomach
- ache than in the category of exp(i pi) = -1.
