And it certainly doesn't mean your brain is neither deterministic nor
But I *can* predict what my brain will do 30 days from now if I decide to
do something in 30 days. That means that what is determining my brain's
behavior (in addition to whatever physiological realities are in play) is
my personal will.

There is no break at all. Did you not see the part about top-down,
bottom-up, center-out, and periphery-in causal influences all being
dynamically interactive? When I make a decision about throwing the ball,
the public symptoms of that decision can be seen as billions of
simultaneous and near-simulataneous events, retro-causal events,

When did I ever say that the brain does things by itself? Why do you keep

Let's say that you are looking at a live video of someone's neurons as they
decide to throw a basketball four inches in the air or three feet in the
air. What happens? What does it matter? The result is the same. Whether it
is at the level of the entire brain, a particular neural pathway, a group
of neurons, membranes, ion channel, molecule... it doesn't matter at all
because they all are changed according to what the person decides. The
person's decision could be pushed from the neural level also, but we would
need to do that intentionally because transmembrane potentials don't know
what a basketball is. Also, your entire model needs a complete revision
since human glial cells have been discovered to increase the performance of
mouse brains. All of our assumptions about coded electric signals as
fundamental factors of consciousness could now easily be wrong.

It is observed any time a person exercises their voluntary will and we look
at what the brain does. Look at Libet even. We don't see sudden responses
coming out of any inevitable physiology of ions, we see semantic responses
to sensory events. What is your claim, that the test just happens to
correspond to a moment when the ion balance was drifting toward an action
potential anyways? What is your theory of how membranes react to non-local

Most scientists, but hardly all. If you talk to them, you will find that
many have private opinions which are very different from what they would
attach their name to professionally. When I went to the consciousness
conference in Tucson recently, of the people I met I would say that less
than 5% hold this 19th century view.

Why? Where is that dictum from?

You are assuming a bottom-up topology. If you flip it over, it is easy to
see that wholes are not mechanistic, it is only parts which seem
mechanistic to wholes. It's all about perceptual relativity - which I don't
think you even notice that I have been talking about all this time.
Whatever experiment we can do to try to defeat perceptual relativism will
only end up confirming the bias of the experiment.

We are the experiment. When we want to move our arm, an electric field
changes. Do you deny this?
