Not just their quantity, but the relationships of their connections to each

This is functionalism, it is what things do that matters, not what they are

You are defining the process as everything that happens in the middle, but
how much of that everything is relevant to the outcome?  If a neuron
releases 278,231,782,956 ions instead of 278,231,782,957 is that going to
be relevant to how the mind evolves over time, or what qualia are
experienced?  What about neutrinos passing through the head of the person,
are those important to the model of the brain?  I think you would find that
a lot of the processes going on within a person's head is irrelevant to the
production of consciousness.  In an earlier post you mentioned hemoglobin
playing a role, but if we could substitute a persons blood with some other
oxygen rich solution which was just as capable of supporting the normal
metabolism of cells, then why should the brain behave any differently, and
if it does not behave differently how could the perception of yellow be said
to be different?  The mind experiencing the sensation of yellow isn't going
to say or do anything different if its outputs are the same.  The two minds
would contain the same information, and thus there is nothing to inform the
mind of any difference in perception.

My belief that dualism, and mind-brain identity theory are false, and the
success of multiple realizability, functionalism, and computationalism in
resolving various paradoxes in the philosophy of mind.

Cartoons aren't systems that receive and update their state and disposition
based upon the reception and processing of that information.

It is more than a one dimensional quantity, I agree.  It is a value of
rather high complexity and dimensionality existing in the context of your
neural network.  Since your neural network is highly complex, the effects
the perception has (what it takes to define it) is likewise highly complex.
 I think the primary reason you have come to your conclusions, while I have
come to mine, is that you think qualia such as yellow are simple, while I
think the opposite is true.  If visual sensations were so simple, why would
30% of your cortex be devoted to its processing?  This is a huge number of
neurons, for handling at most maybe a million or so pixels.  How many
neurons do you think are needed to sense each "pixel" of yellow?

So would you say a rock see the yellow of the sun and the blue of the sky?
 It just isn't able to tell us that it does?

That is the reason for seeing different colors is it not?  What defines red
and green besides the fact that they are perceived differently?

That would be confusing, I couldn't tell if I were looking at a bush or
eating.  I wouldn't know the relative position of the bush in relation to
myself or other objects either.

We have some reason.  There are species of monkeys where all the females are
trichromatic, and all the males are dichromatic.  When the first trichromats
evolved, did their brains and senses not conjure up a new palette which
never before existed?

The first being which had both senses capable of distinguishing different
frequencies of light, and a brain capable of integrating those differences
into the environmental model of that being.  It is likely that this being
did not perceive red light in the same way we do, it is even possible you
don't perceive red in the same way I do.  For all we know, your brain may be
the ancestor of red as you know it.  Two people can taste the same thing,
and one person likes it while the other dislikes it, just like two people
can read the same book and like it or dislike it.  It depends on the
structure of their brains.

If it were just stored in memory passively, it makes no difference, but if
the computer attempted to parse or otherwise process the data then the
format it is in does become important to the proper processing of that

What do your qualia do?  They inform you.  Do you have an example of
anything that is informative but is not information?

Our imagination and thoughts do not give us the ability to completely
reprogram ourselves.  If they did, people would corrupt their minds or put
them into unusable states by thinking certain thoughts.  Minds would crash
in the same way our computers so regularly do.

You mentioned earlier that light frequency is a linear value.  Why then just
three primary colors?

I would say qualia are a function of minds, which are a function of
processing, which is a function of matter. (which Bruno would add is really
a function of arithematic)

If you think the primary colors are fundamental, then to explain colors such
as pink, you must add the concept of information and quantity to the
fundamental primary colors.  For example, pink = 2 parts blue, 2 parts red,
1 part green.  So this quantitative information is a necessary component of
the experience of pink.  Once you get to this point, you might as well
abandon the fundamentalness of the primary colors, they are just markers
corresponding to activity of different neurons.

That's the wrong question to ask, when a person in a coma
is functionally very different from a person who is conscious.  This
functional difference is absent between a Turing emulation of a brain and a
brain.  They would both be similarly capable.

Were those smart sweepers not "sensorimotive" in their attraction toward the
food particles?  Did you try running that simulation?
