Jason & Colin, I'm going to just try to address everything in one
I agree with Colin pretty much down the line. My position assumes that
worldview as axiomatic and then adds some hypotheses on top of that.
Jason, your original list of questions are all predicated on the very
assumption that I've challenged all along but can't seem to get you
(or others) to look at. I have experienced this many many times
before, so it doesn't surprise me and I can't be sure that it's even
possible for a mind that is so well versed in 'right hand' logic to be
able to shift into a left hand mode, even if it wanted to. I have not
seen it happen yet.
As Colin says, the assumption is that the logic behind the Turing
machine has anything to do with the reality of the world we are
modeling through it. If you make a universe based upon Turing
computations alone, there is no gravity or fusion, no biological
molecules, etc. There is only meaningless patterns of 1 and 0 through
which we can plot out whatever abstract coordinates we with to keep
track of. It means nothing to us until it is converted to physical
changes which we can sense with our eyes, like ink on tape or
illuminated pixels on a screen.

You can simulate it as far as being able to model the aspects of it's
behavior that you can observe, but you can't necessarily predict that
behavior over time, any more than you can predict what other people
might say to you today. The chemistry and physics of the brain are
partially determined by the experiences of the environment through the
body, and partially determined by the sensorimotive agenda of the
mind, which are both related to but not identical with the momentum
and consequences of it's neurological biochemistry. All three are are
woven together as an inseparable whole.

Any intelligence is something beyond the behaviors of matter. It's not
as if a Turing machine is squirting out omnipotent toothpaste, you are
inferring that there is some world being created (metaphysically)
which can be experienced somewhere else beyond the behavior of the pen
and tape, motors and guides, chips and wires.

Colin, here is where you can consider my idea of sensorimotive
electromagnetism if you want. What really is an EM field? What is it
made of and how do we know? My hypothesis is that we actually don't
know, and that the so called EM field is a logical inference of causal
phenomenon to which matter (organic molecules within a neuron in this
case) reacts to. Instead, I think that it makes more sense as sense. A
sensorimotive synchronization shared amongst molecules and cells alike
(albeit in different perceptual frames of reference - PRIFs). If two
or more people share a feeling and they act in synchrony, from a
distance it could appear as if they are subject to an EM field which
informs them from outside their bodies and exists in between their
bodies when in fact the synchronization arises from within, through
semantic sharing of sense. It's reproduced or imitated locally in each
body as a feeling - the same feeling figuratively but separate
instantiations literally in separate brains (or cells, molecules, as
the case may be).
All of our inferences of electromagnetism come through observing the
behaviors of matter with matter. In order for EM fields to be a
literal phenomenon independent of atoms, it would have to be shown
that a vacuum can detect an EM event in a vacuum. That this is so
problematic underscores the primitive level of our assumptions about
EM. We can't not be matter and can't not use matter to detect EM so
that we aren't even consciously aware that we are ascribing waves and
arrows to the behavior of materials rather than just mathematical
particle-waves. Like the lines radiating out of a cartoon light bulb,
the radiance is a subjective experience within our PRIF as sighted
humans, not literal rays of nano projectiles striking our eyes.
The waveness or particleness is in the eye of the beholder because it
is literally the beholder which is actively experiencing the effect.
The effect is figuratively the same for each beholder within the same
PRIF although locally instantiated, but outside of the PRIF, such as
in lab experiments with photomultipliers, the effect is not only
instantiated separately on the local level, but on the figurative
level as well. A different metaphor is invoked if you are working with
beholders of literal sequential events compared to organic beholders
of a greater range of qualitative experience. Hence the light that we
see through our eyes is not just electromagnetism, it is the
sensorimotive content of our nervous system's visual sense.

Yes, I get this as well. Others seem reluctant to commit to it, which
I see as sentimental-protectionist to the occidental perspective, and

Yes, I get this too. The model of the Krebs cycle doesn't produce
anything by itself. It's just a mathematical-logical understanding
(which is itself a sensorimotive experience and not a physical
artifact which exists independently of our minds) Again, it is
instantiated separately in each of our minds, with a degree of
distortion, and is relevant only to our PRIF in relation to a
biochemical level PRIF. On the level of the molecules, there is no
Krebs cycle, just as the cycles of the stock market are not the actual
activities of human beings doing business.

To my mind it is profound confusion as well, but my ACME-OMMM model
predicts that it would be how it should look from the OMMM facing
perspective. The mind can relate to the world as computed models too,
it's just using the cognitive PRIF only instead of the full spectrum
of PRIFs accessible through our perception. Such a worldview is 'black
and white' relative to other perceptual modes, but it provides higher
resolution of linear literal functions. In it's extreme though, it has
no capacity to allow for metaphorical resonance. Which is a problem
for consciousness, since it's made of metaphorical resonance of

Yep. You said it.
