A good few years ago I read The Emperor's New Mind by Roger Penrose. Having recently read some philosopy primers I was wondering about the links between this book and the question of free will.
From what i remember the final (speculative) argument went
- (Roger thinks) there is free will
- Where might free will be located?
- There are microtubules in biological cells
- These are about the size where quantum physics becomes classical
- That's a mysterious part of physics that we really don't know much about
- Therefore that's a good candidate for free will
While that might seem a flippant summary - it isn't meant to be. I was quite taken with the argument at the time.
So my questions are
- Has Roger Penrose put forward a form of dualism there. Has he located a ghost in the machine or is this a different argument?
- Did this argument ever go anywhere. Did anyone build on this or was it just some speculation that went nowhere?
Also - it's possible (likely) that I have completely misunderstood the Emperor's New Mind conclusions. Please feel free to correct me.
