Hi Ben,
It seems evident from what you say here, that you haven't seen the video on
detecting qualia: https://www.youtube.com/watch?v=AHuqZKxtOf4 . I think
this will answer most of the questions or issues you are pointing out here.
Also, you use the word "red" in ambiguous ways. For me, the word "red"
means something has a property such that it reflects something like 650 nm
light - the initial cause of a perception process. The final result of
this perception process is our knowledge of the "red" thing. This knowledge
has a “redness” quality you can experience. When you say “red”, I often
can’t tell which one you are talking about. This is important because, in
cases like inverted qualia, my redness could be more like your greenness,
which we both represent “red” with.
You indicated I'm overly confident with this stuff., but the only thing we
know for sure is that conscious experienced includes at least 3 elements:
an ability to experience redness quale, and ability to experience a
greenness quale, and a mechanism the binds these two qualia together to
make a composite experience qualia of redness and greenness. It is this
binding mechanism which enables us to be aware of both at the same time, so
we can compare them, qualitatively, enabling us to verbalize things like:
“yes those are qualitatively different or the same”. You like to think of
a redness quale as particular patterns of firing neurons, John thinks of
them as ineffable, or not sharable, or not approachable via objective
science. Stathis thinks that redness is something functional, independent
of any particular hardware. All these are still theoretically possible, or
not yet falsified. So, I need to have a term to use that represents all
these possible neural correlates of redness to all people. Since most
people’s theories about the neural correlates of redness might be are
overly complex and lack specificity, so it is almost impossible to describe
to people what is required to detect qualia or eff the ineffable. (in the
various week, stronger, and strongest, ways. We need to have a basic
understanding of the requirements to think about this kind of qualitative
theory, so we know how to test for all the many theories, to find out if
people have inverted qualia, and so on.
So, I’m only confident that we can experience multiple qualia, that
something in the brain is the neural correlate of each, and that there is a
binding mechanism that enables us to experience all of these, as a
composite qualia enabling us to qualitatively compare them.
So, in order to verbalize this kind of qualitative information, I need a
simple theoretical example which could be use in some simplified world to
test the various theories of what qualia might be. Then once everyone,
with all their diverse ways of thinking about qualia, can understand how to
think in these kinds of qualitative testing ways, they can know how to test
if their particular theory is correct or not, and how we might be able to
eff the ineffable with their theory.
So, instead of trying to describe this relatively simple qualitative theory
in all possible, mostly very incomplete and non specific ways of thinking
about qualia, I just use this simple theory of how people in a simplified
world would be able to detect, eff, qualia and prove various qualitative
theories.
You, Stathis, and everyone keep complaining about my usage of glutamate,
and pointing out problems with it. But this is missing the point. “Glutamate”
is just a simplified term that represents whatever is doing the neural
function of a redness experience in an objectively and quantitatively
describable way in a simplified world. If you think a redness experience
is a set of neurons firing in a particular pattern, then just substitute
that idea whenever I use the term “glutamate”. Stathis needs to substitute
the term “glutamate” with something “functional” that is a redness quale,
and so on. The important part is just that we need some over arching
qualitative theory we can all understand, so we can talk to each other, and
propose ways to objectively prove which of our various theories are the on
right theory, and how to tell if people have inverted qualia and so on.
Once a person understands how qualitative theory works in a simplified
world, then you can use the same general qualitative ideas to better
understand qualia in the real world.
