WHAAAAT?????
Did you think you were just going to slip that in and I wouldn't
notice?
So cool, as long as I give you the schematics of my car and tell you
where I'm going to drive to, you will be able to deduce where I'm
going to drive to? Wow, that's almost better than nothing at all.
There is no way that you are serious. You are trolling me, brother.

I'm not the one saying that the brain could be modeled physically and
make predictions from it. That's your position, remember?

Yes, they do, but so what? You could have those factors without any
kind of decision to move your arm. You can electrocute a severed frog
leg but there is no decision there by the frog. The physiological-
electromagnetic factors alone do not replace the subjective decision,
nor does the subjective intention replace the biology. They are one
and the same phenomenon but because we are stuck on the back end of
it, we see the front end as a different thing. From a truly objective
point of view, however, there is no reason to presume that my
imagining Bugs Bunny eating a carrot is any less a part of the
universe than ligands and ion channels. It's all real, it just has
very different characteristics on opposite sides of the process.

8. No, you are wrong and you know it. You just got finished admitting
that you need me to tell you how I am going to turn my steering wheel
for you to tell where I'm going to drive, so where are you pulling
this out of? Repeat after me: Some neural activity is spontaneous. It
may not be predictable by any model but rather is determined
dynamically through subjective intent. Physical laws do not tell the
future of subjective intentions.

That is the point, the neurons release the neurotransmitters so that
they will be where they need to be for the other neurons, so that your
will can be executed through the system, or so your perceptions can
change in the appropriate way.

Yes, depolarization will occur when a neurotransmitter changes the
charge of the membrane, but a subjective intention is a spontaneous
change to the charge of many neuron membranes at once. It goes both
ways. Electromagnetism is sensorimotive. If electromagnetism doesn't
think and feel, then what do you think all that stuff is on the
fMRI's? Your thoughts *are* an electromagnetic change in the tissue of
your brain. You direct that change consciously in many cases.
The neurological consequences follow from that - teleologically, down
the spine, to my fingertips, then the keyboard, then the computer,
internet, your computer, your screen, your eyeballs, your visual
cortex, where your subjective interiority; the sum total of all of
your experiences as yourself, imitates the sense your eyes make of the
characters on the screen so that your version of what I'm saying makes
sense to you in natural language. We are directing our nervous system
to do these things for our personal semantic reasons, not to satisfy a
biochemical regimen.

ROFL. I knew you were going to say that and I almost added my
prediction at the bottom. I knew that you were going to claim that by
"spontaneous" they really mean "utterly non-spontaneous and
predictable".

And the transmembrane voltages respond to.... NOTHING. That is why
they are spontaneous. Not cyclically. Spontaneously.

7. You are the magician, not me. I explain how our ordinary experience
of talking and thinking is a natural process, why it seems unnatural
(because we are only seeing half of it first hand), and how it relates
specifically to neurological function, electromagnetism, physics, and
cosmology. You are the one pulling the epiphenomenal rabbit of
consciousness out of the deterministic hat - with no theory, not hint
of explanation, just the bold and robotic re-assertion that
consciousness, will, and indeed biological life can only be magical.
You are actually very close to understanding the truth - that's what's
so frustrating. All you have to do is take your understanding of how
this works and run it in reverse.
Start from the subjective and move out. Forget all that crap about
ions and neurotranmitters - which may as well be ghosts and goblins
since you know absolutely nothing about them first hand, just set that
aside for a second and look at what it is actually like to be. Take a
walk outside. That is the universe. You seeing that is what the
universe is doing. That's what your brain is there to do, not just to
survive like a goddam slime mold. Wake up, man! You exist.
