Thanks for jumping in with so much great thinking. I think you are really
I must really be failing at communication. Both you, John, and others
often appear to disagree, but then what you talk about as if it was a
different view than what I was saying, it is exactly the point I was trying

Yes, all this is all exactly what I've been trying to say.

Right, what you are saying is the red quale changes to a black quale,
right? Again, that is what I've been attempting to say when things 'fade'
or 'just go black'.
These are the conscious changes I'm talking about. If you know something,
whether it is red or black, or fading or whatever, there must be something
that is that changing conscious awareness.

Exactly what I've been attempting to say.

Thanks! Yay, at least I"m making some progress. Yes, the main ideas are
what everyone agrees on: that we have qualia, and as you say qualia are "a
mental construct" that is our conscious knowledge. This is the only
doctrine contained in the general super "Representational Qualia Theory
<https://canonizer.com/topic/88-Representational-Qualia/6>." The only
thing everyone disagrees about is the nature of qualia. Communicating the
high level RQT ideas about what 'qualia blindness' is, and how there is not
a "hard mind body problem", it's just a color problem is already very
difficult to communicate. It requires some major surgery to people's naive
epistemology of color. So we simplify everything as much as possible.
(only talk about red and green - no other colors or more subtle qualia).
Glutamate being redness is only in the small low level minority camp "Molecular
This camp is the simplest and most importantly, easy to falsify. If
someone experiences redness, with no glutamate, redness = glutamate
prediction falsified. The ease of falsifiability is what is important.
For example, I see no possible way to falsify most of the other theories,
especially the leading consensus camp which Stathis supports: "Functionalism
<https://canonizer.com/topic/88-Qualia-Emerge-from-Function/18>". If they
could provide any easily falsifiable example of what redness could be, I'd
be happy to use that in place of glutamate, but they never provide anything
even close to that. It's all just sloppy hand waving with the small
required "a miracle happens here" step they always ignore. Of course, it
is my conjecture that if they did provide something that could be redness,
it couldn't be that for the same reason it can't be glutamate, proving the
absurdity of their substitution argument.
So, we don't use glutamate because it is likely true, we use it because it
is the easiest to falsify and easiest to understand. The general idea is
just that whatever redness is, it is objectively observable (giving us only
an abstract description of such.) I often describe an overly simplified
physical world with only red and only green, and only in that simple world
is it glutamate that has redness and glycine that has greenness. If you
can understand how experimentalists in such a simple world could fully
describe the behavior of glutamate, reacting in a synapse, without knowing
this was redness, then you can apply that same non qualia blind thinking to
all more capable theories. You've got to understand qualia blindness,
first, in the simplest possible world. Then you can start to observe the
complex brain in a non qualia blind way (use more than one word for all
things red) so we can discover what it is that does have a redness quality
- finally giving us the required factual dictionary between the abstract
objective and the qualitative subjective. Until we do this we will
continue to have no idea what color anything is. In other words, you just
start with glutamate and redness are abstract labels for the same thing.
Once you falsify glutamate, then substitute glutamate for your next working
hypothesis (starting with the easy to falsify one's first) until it can't
be falsified. Then you will finally have the required dictionary
definition for which abstract description of something in our brain is a
description of what we can directly/subjectively experience as redness.
Incidentally, I think you might have been too reductionist in your

Um, yea. What you say below (as illustrated in this "Perception Inverted
section of the video) proves what you say above is mistaken, right? You
can have redness, in a brain, in a vat, with no light, and no retina. so
we're not talking about the retina. Redness is the final result of
perception, far downstream from even the optic nerve, let alone anything in
the retina. You just need to stimulate the optic nerve the same as the
retina would and due to this input, the brain creates knowledge or a
construct made out of something that has a redness quality we can
