I could change it at the last minute also. I may not be able to predict what your brain will do 30 days from now, but that does not necessarily mean your brain is not deterministic. And it certainly doesn't mean your brain is neither deterministic nor probabilistic. > What you have not considered is that your assumptions about the universe > could be based on jumping to the wrong conclusions about matter and > consciousness.

I understand what you mean completely though. No, I think you believe the brain does things "by itself" and you don't understand how an experiment could be set up to demonstrate this. >> You could take a neuron and measure the >> transmembrane potential which will indicate according to our knowledge >> of physics that the neuron will not fire, but then observe that - >> CONTRARY TO PHYSICS - the neuron does fire. > > > The whole point is that the transmembrane potential can and does change at > any time.

It is due to the difference between the sum of positive and negative ions on either side of the membrane. Do you know how the ion concentrations are set? Ions diffuse across the membrane following their concentration gradients, diffuse more quickly through specific ion channels, and are transported against concentration gradients via energy-dependent transmembrane proteins. You would be surprised if the balls in a pinball machine just started levitating or something all by themselves, and yet that is what you claim happens in the brain. Where does it happen, and why has it never been observed? >> And >> insofar as physics is mechanistic - deterministic or probabilistic - >> the behaviour of the body will be mechanistic. > > > That is your theory.

If the general does not behave mechanistically then the army as a whole doesn't either. The only way the general could behave non-mechanistically is if some part of him does not; for if every part behaved mechanistically then he and the army would behave mechanistically. So which part exactly of the general behaves non-mechanistically, and could you suggest an experiment to demonstrate your hypothesis is right? >> Consider only the publicly observable behaviour of any system in the >> universe.

But charge and electric fields are well-described mathematically in physics. Do you have any experiments showing that electric fields behave contrary to the well-understood equations? -- Stathis Papaioannou -- You received this message because you are subscribed to the Google Groups "Everything List" group.
