- Yes, and with interest too. Trouble is net news takes a couple of

- maybe you said them before and I wasn't paying enough attention.

- Yes, but I'm not sure I want to say that all mental activities aren't
- physical as well. This is a very big question, but I'm inclined to say
- that if you ask physical questions you'll get physical answers, and
- they'll make sense. My only reservation might be about self-consciousness.

- rather than something provable from anywhere else. If somebody asks,
- "But what measurable change does this 'self-consciousness' have on the
- universe?", I'd say, simply the fact that many people (not just me)
- discuss it and think it's important. Would a super-clever AI machine
- start of its own volition to reflect on its own self-consciousness?
- I doubt it. But maybe it would. This is only speculation now, so
- enough said.

- As I said, I think if you ask physical questions, you'll get physical
- answers. So even from your point of view, it should be possible to
- argue for free will. Now this is just off the top of my head, but I
- can think of a line of argument:
-
- 1. The universe is not deterministic. Quantum mechanics deals only
- in probabilities. As well as this, wherever chaos occurs, the future
- very rapidly becomes uncomputable. The overall result is even if
- some vast computer could know the position and velocity of every
- particle at some time t, (which it couldn't with certainty anyway),
- it couldn't compute the configuration for 1 second later -- and in
- any case, the configuration would include its own computation, so
- I think it would be in principle uncomputable. Certainly in practice.
-
- Thus the picture on your 4-D manifold isn't determined by anything
- other than its actually occurring. My information flow argument
- could be applied here as well. So your decisions aren't determined
- by anything other than your deciding them. This sounds like free
- will to me [if it walks like a duck... :-) ]
-
- 2. We experience free will. It seems to us that we have it. In the
- absence of any compelling argument to the contrary, shouldn't we apply
- Occam's Razor and say that free will is real?
-
- Cheers, Mike.
