Well, that is interesting. Wasn't sure that any "arised" form the
sensory input *outside* of the brain?! Great trick that term-
"arised"! - kind of like a magician pulling a rabbit out of the hat,
or like Jesus pulling Lazerus out of the grave. We'll have to watch
that left hand when the right is trying to distract us!
Physically, sight originates with a kind of ballistic interaction with
the eye. Energy is transferred from the environment and into the
brain, the impulse or signal presumably being somewhat lost in thermal
noise eventually but not before affecting persistent structure
(storage at least till I am senile ;) ), where it can be stored as
potential energy in chemical bonds and where its information content
can be preserved as a message.
But you are saying that a percentage of conscious activity arises
directly from from within the brain. So I guess I have two questions:
1) Are you implying that there is a physical model of the brain that
is sufficiently detailed to track the energy that presumably arrives
in the brain ultimately from food and distinguish its amount from that
which arrives through the sensory apparatus? And is the ratio you
described 80/20 is based on that? Meaning is it a ratio of the
energies from these two sources? I would have thought that it was much
lower for the signal. I am not talking about the nuclear energy in the
food which is obviously much higher but just the chemical energy of
the valence relationships. I think the signals coming in provide very
little of the energy. Much less than 20%
I have not done the math (but based on your post I will) of the ratio
of energy of the chemical bonds that are destroyed by the respiration
oxidation reduction reactions in my brain compared to the energy of
the light incident on my eyes and the sound energy deposited on my
ears and the energy associated with tactical impulses etc. but I will
bet dollars to donuts that food provides much much more than 80% and
most of the "conscious activity" if you mean the electro chemical
activity of my brain and not consciousness directly, is received from
food and not from the senses. Now I will grant that that small part
that comes in from the senses is critical.
You can see it in a typical transponder design. Once the signal to
noise ratio is established at the low noise amplifier at the antenna
the signal can be manipulated and processed all over the place using
amplifiers the energy of which has nothing to do with the signal. Or
are you saying 2) that 80% of the information content comes from
somewhere other than the senses? Well, then we get into a detailed
discussion of Claude Shannon's work and again I don't see where you
get the ratio. You would need to define all possible messages and then
track the equations he came up with to show how the various signals
result in the discrimination between the possibilities and here I
think that you might find that the signals coming in are providing
most of the information - much more than 20%- and that the food is
providing only the amplifying energy.
I note that there are others sources also. One can stick an electrode
into a brain and transfer energy directly. Also one can - well -
really shake a head! Make it "see stars"! lol. :)

Now you have used a term "gives rise" and you have used the term
"arise" so you have done it twice! ;) and you have said that you see
"no reason at all to assume that anything" other that "chemistry and
electricity" does this. Lets look in detail at what that means.
First of all, lets look at what "chemistry and electricity" means. I
will take this ultimately to be reducible to meaning "all of current
physical theory" so I assume that you mean that if I take all of the
current physical theory and set up the interaction of particles, the
structure, etc of a brain that that will "cause" consciousness. Now I
have no problem with the belief that in fact that will happen - that
consciousness will occur if you arrange the matter that way - and will
cease if you de-arrange it- but here is the problem I have when you
say "no reason at all to assume that anything....beyond...electricity
and chemistry...." etc
The problem is that the sum total of all electrical and chemical law -
even if extended to all physical law - does not in fact predict
consciousness. In fact there is no physical property of the assembled
and functional brain that in physics or chemistry would cause one to
say "and then it becomes conscious" or "and then it sees". Physically,
it remains a natural objective structure and there is no existential
implication. There is no "seeing" that results from the physical
theory, there is just dynamic interaction of the particles, correctly
as you have pointed out I think due to electrical forces between atoms
and in particular their valence electrons, which is what non-nuclear
chemistry is. So what the physical theory predicts is just a slightly
different arrangement of the particles - not consciousness - on
principle. Physics does not predict consciousness. Therefore I
conclude that there is some other principle "beyond the electricity
and chemistry" that is surely required. Else we can, if you want,
redefine what "electricity and chemistry" are (take it beyond Guass'
laws or beyond QED).
But we must do something as there is nothing in those theories that
predicts consciousness at all!
I have studied the laws of Electricity and Magnetism and the
associated laws of dynamics in classical and modern theory as closely
as I can and really must object that they would allow one to predict
that any structure would become conscious. That is simply not a result
of the theory. The theory does not predict that and it is a scientific
misrepresentation to say it does. Can you show some idea or hypothesis
on how these laws actually predict what you are claiming that they
predict? Not a specific structural hypothesis but how any law that
ultimately just deals with the change in "location" or in the modern
sense in "the probability of appearing of a particle" because there
the "appearing" can be inside of an instrument and does not refer to
consciousness but rather to energy exchange, can ON PRINCIPLE ever
hope to realize such a fantastic claim as to predict that
consciousness will occur?
Physical laws just show how things move! They are only intelligible
existentially when experiences for which they predict the object
content are in fact experienced. So, for example, if I take an
electromagnetic wave at Ku band frequency and shine it in your eye the
physics and chemistry will predict that as I slowly raise its
frequency that it will eventually pass through the various frequency
bands till it comes to the optical range and begins to hit the
resonant frequency of the forced harmonic oscillation of the atoms in
your eye (speaking classically) and that oscillation will be
physically translated into electric current and electro-chemical
signals that will travel out into the brain is some pattern and then
describe the resulting chemical and electrical "endgram" in the brain.
That's it. Nothing more. No matter what happens they predict only that
these particles will have a certain motion and result in a certain
structure and result in a certain motion of that structure. Only when
I append the additional phrase: "And then you will see red light" does
the prediction contain a reference to consciousness and that statement
"And then you will see red light" is not a physics statement. It is
not chemical and it is not electrical statement and it is no-where to
be found in any of the physical laws (Guass's, Newton's, QED) that I
know of.
If fact the problem is even deeper. Science itself cannot be conducted
based on physical theory alone. Let me explain what I mean. Science in
the post Aristetilian sense is dependent on observation and comparison
of that observation with prediction. The physical theory can describe
for example that an electric current will occur in a wire and that the
arm on a current meter will move and that, if illuminated by an source
of electromagnetic radiation of the right frequency will reflect that
light and that the light will move into your eye if you point it at it
and etc into the neurology etc but it will never form the phrase that
goes "and then you will see the needle move". So the very predictions
of science on which experiment can be made are inherently non-
physical. Science is a study only of nature and nature itself is only
part of experience.
To put it simply as I can all of physical principle can only predict
the "location" (using the term loosely in a quantum theoretical sense)
of matter. But there is not a shred of evidence in electricity and
magnetism, not a hint, in all of physics, that conscious would ever
result from any physical structure. Consciousness is not a consequence
of the current physical theories, irregardless of what initial
conditions are set up or what version one uses (classical, modern
etc) . In fact, with respect to neurology, it just results in a
prediction about the structures that will occur if for example light
is shined into the eye. It can tell you in detail what will happen to
the arrangement of molecules but makes no prediction that then, in
fact, consciousness will occur.
If fact physical theory alone is not capable of even predicting the
results of its experiments! if I think very carefully about it. Some
other principle like "What you see is the light" or something not in
physical law must be used!
I challenge you to show me wrong on that and show me where or how it
does. I just do not see it.
Now you may say I am making a mockery of science and the scientists do
daily predict the results of their experience. In a sense you would be
right but it doesn't help. Let's look at that.
Even if you include predictions about the fact that "the various
meters and LEDs that scientists see will in fact be seen" in the term
"physics" or "science" by connecting it to nature - which is
reasonable because it is in fact the experimental aspect of physics,
and it is correct to claim that it is a "natural science" then there
is still a problem. Basically, the theory would then consist of two
parts - one is the part that contains the laws of motion of the
particles, the electricity, the chemistry, the neurology etc That is
that part that we call "chemistry or electricity" etc and it would
then need another part that associates this with some experience. That
latter part would not be chemical nor electrical. So while you could
get away with calling it science by expanding the term beyond the so-
call laws of physics to something that is a reference to consciousness
(like "and then you will see red") you could not reduce that part of
the science to electricity or chemistry. So the claim you are making
would still be false. Science would now allow you to predict that if I
attach a Van deGraft accelerator to a particle detector, that *you
will see* this LED start counting upward but you will then not be able
to reduce science to electricity and chemistry!
Or if you prefer, a scientist could predict that if he stimulated the
right part of your brain that "you would then see red" but that last
phrase is devoid of any physcial read - electro-chemical - content. It
goes beyond it and is in fact a phenomenological description. So you
would have restored physics from my making a mockery of it only be
extending it to phenomenology and the reduction you attempted would
again fail.
Either consciousness is not physical or another physical theory is
needed, one that is not physical or in the end even natural. But the
very terms physical and natural have been deliberately set up as
distinguish from the terms metaphysical and supernatural in western
thought at least, and therefore one can go further and claim that no
physical or natural explanation for consciousness will ever be - nor
can ever be -proposed, and the reason is because consciousness itself
is not natural or physical. It is metaphysical. It is supernatural.
This does not mean anything other than consciousness is not what it
experiences or better consciousness is not its thetic content.
This has nothing to do with the latest advances in neurology. This has
been known for centuries. The problem is only that the neurologists
are ignorant of the meaning of their own philosophical, artistic, and
religious traditions and consequently ignorant of the meaning of their
own work. It is not surprising. It is not their field. They are, after
all, scientists and not philosophers, or artists, or priests and have
not studied the right texts.

The term mystery has a very long history. There is no chance that
neurology can remove the mystery. All of material existence is
contingent! The following statement is just ridiculous: "This is not
as big a mystery as the posts here seem to think." It is perhaps
exactly the opposite and the fact is that the reason this group even
exists is because people are trying to grasp and articulate the extent
to which it is a mystery. You see in a strange way to realize its
mystery is what it takes to understand it - or is a direct result of
understanding it. It is in fact what mystery itself is. It is the
source of all mystery. So, unlike in science, when mystery is
seemingly removed through understanding, when it comes to real, non-
scientific, or non-natural experience, mystery is not removed but
heightened - or rather ones appreciation or realization of it is
improved and one realizes the extent to which all experience is -
inherently- - in essence- mysterious.
A failure of this reasoning caused the so called "shipwreck" of
philosophy around the time of Kierkegard and Nieztche and is the cause
of the existential boredom and crisis underlying the works of Samuel
Becket like the play "End Game" or "Waiting for Godot" or other
absurdist drama. It is the source of the crisis in No Exit by Sartre.
It was mapped out before WW2 and in fact as early as the writing of
Genesis. The issue has been, I think, decided. (Or maybe not as so few
seem to have realized the meaning of the work done)
It (purely scientific reasoning) was rejected by the Beatific Poets
who "re-discovered" Hinduism and Bhudism - (I know - whenever a
European "discovers" anything we eventually find out that an Indian -
of some kind ! ;) - had been living there for a long time before -
Ha! ;) )
Haven't you seen 2001 a Space Odessy by Kubrick? That was done in the
60s long before the current surge in neurology got its start.
The non-mysterious thinking has also been rejected in all of the
mystical traditions of the religions (see Sufi-ism, Kabala, Zen, or
the mystical aspects vice the fundamental aspects of St Teresa, or St
John of the Cross) - Unfortunately and tragically not in their
fundamentalist counterparts.
Or you can just ask Molly about synchonicity. She got it from Jung and
that term was defined long before neurology got much of a start. I am
sure she will tell you that it holds a little mystery and wait till
they understand that!
Where we will go from here we do not know. But one thing for sure
anyone who tries to interpret neurology as having any central bearing
on the Mystery of Life and I capitalize deliberately, is just plain
wrong. They will only show a more detailed knowledge of the physical
structures associated with the experiences. But we already knew it was
in the brain! The only issue that neurology will decide is exactly
where in the brain and what the chemical and physical correlates are.
That is all. That is all on principle. Only when combined with
phenomenology as Husserl wanted to do for psychology, over a hundred
years ago now - its not a modern discovery - it has nothing to do with
"recent advances" I think, can it be of use. We need to understand
what has already be understood before we can advance!

Fine. So now we know which side its on. Before we knew it was "in the
brain" now we know its on the "right side". Let's assume we know it
all - that means we can predict the exact position (speaking
classically in a physical sense) of every particle! Then what! We are
still no closer to eliminating the mystery. It will not mean that it
is.
A duality that
> is usually ultimately described by the subject as god-like.
Ah but there is the difference you see. God-like is not God. Just as
you can stimulate the brain so that the person sees red even though
there is no optical stimulation of the eye so you can create all kind
of experience by manipulating the brain. But don't you see that this
does not do much more than saying that if you create a baby that it
will see or that if make a man blind or kill him he will not? And we
have known that for centuries! How will modern neurology teach us more
than that?
(Don't get me wrong - I love science and eagerly await reading about
these things when I have time but I just don't see what is happening
now can change much of what we already know. Flesh out the details
maybe.)
Neurology will actually help in the future (near future I hope because
my goose is cooked soon but I am afraid it will be before I get to see
it) but has not much yet. It will help with clarify the morphology of
the experiences. Something like what systematic philosophy tried to do
can be aided by neurology. By understanding the structure in detail we
can help characterize and discriminate subtly between different
aspects of the phenomenology. An example is long term and short term
memory. That kind of distinction can be had by the combination of
psychological experiment with neurology. When that progresses to an
examination of religious experience then it can be very useful I
think. The "varieties of religious experience" can be mapped
neurologically I presume or hypothesize. I obviously do not claim to
know now but I think it reasonable.
In the end it might even help by allowing us to manipulate the brain
so that it is better able to experience the Mystery. Unfortunately,
that same capability will probably allow us to eliminate that ability
and reduce us to a kind of high functioning insect cleansed of any
aesthetic or ethical sense - devoid of any awareness of the Mystery.
That will be a sad day. To do this it need only retain the
interpretation of existence in the will to power. This will retain the
survival instinct which must be retain in order to continue the
species itself, (one wrong move and you get suicide - but based on the
phenomenology I think just a small technical obstacle). But it will
never do away, intellectually, with the meaning of the Mystery. Even
if you blind everyone the light is still there and the fact is that
everyone will still *be* blind.
What will happen is that they will see that the religious foundation
has no correlate outside of the body. They will then conclude that it
is "not real" or "not about reality" but "purely a mental phenomena"
and therefore de-legitamize what others claim to be its meaning. This
has already been tried of course but that will not prevent them from
trying again based on this "new evidence" that shows that the
information is not tied to sensory information.
But hell, that level of destructive capability is not new either. We
can do even better with self annihilation. We can destroy not just one
idea but all of them. We can blow the world up or release some kind of
super virus that destroys the race. So the new neurological kind of
intellectual castration is only a more limited and subtle form of
murder. The old ones have been around a long time and we have been
struggling as a species not to use them so hopefully cooler heads will
prevail and consciousness will not be so low as to reduce us to
intellectually "pure electrical and chemical" entities and then,
based on that false understanding, attempt to eliminate through
neurological manipulation all awareness of the alternative.
So I'll go further then and extrapolate on the data a little. There
will be a struggle. Those who believe that we are "merely chemical and
electrical signals" will at one point realize that while the
endochrine system has been useful in preserving the species by
instilling a desire for life in certain situations it is not itself
indespensable and by carefully engineering the will to power and
identity the species as a whole can be made to function without
Mystery or any of the understanding of metaphysics that is, in a real
sense since I am extrapolating ;), based on our sexuality. They will
realize that the insects had it right and especially the ants and the
bees and the urge to procreate need not be instilled in all
individuals and can be made autonomous even and not dependent on any
conscious correlate. (Hell, truth be known they may even conclude that
consciousness itself is not needed and they just need a kind of
perpetural motion machine!) They will in fact want to eliminate the
consciousness of mystery for the same reason you want to be convinced
and convince us that we are electrical and chemical and for the same
reason that you cannot see that that is false right now without
recourse to neurology. Not for the reason that you are convinced. I
didn't say that. But for the reason that you want to be convinced. For
the reason that you want that position of the "detached observer" that
can manipulate perfectly because of its predictive theories.
See, you did not even know that your "objective theorizing" was based
on a desire. Perhaps there is something to Dennet after all! ;) His
brain is fooling him!
That struggle will be formed when those people come up against those
whom we will try to ready. They will be trained to recognize the
Mystery as the source of what we call good and see that the castration
of the human race by elimination of the cognitive aspects of its
endochrinology would be - well - a crime? - a disaster? - chose a
word. They will be trained to embrace humility and recognize, like
Arjuna in the Bahagavada Gita that the outcome of the battle is not
relevant but that they must still fight out of duty. They will watch
you carefully, form associations that preserve the future of what we
now call "rights" and be willing to sacrifice their own lives for that
meme which is what we now refer to as "the Good".
An important part of that struggle is ongoing now and it is the
necessity of clearly rebutting the "mechanical" interpretations of our
Being-there, not because we want them to be wrong, but because they
are wrong and the consequences of the culture loosing sight of that
and simultaneously gaining manipulative control over neurology will be
parallel to the development of large scale nuclear weaponry and must
be fought through the limitation of power of those at the apex of
primate hierarchy.
We only just missed blowing a large part of our civilization away
during the Cold War. Maybe we can do it again.
Just read God Emperor of Dune by Herbert. Its not my idea. Its been
around for a while. Read Frankenstein for crying out loud. But
whatever you do make sure its not recent work and make sure its not
scientific!
