You have to consider the organization at the right degree of detail. They
are not functionally identical as they are each processing information in
different ways, one is inverting the symbol after the retina, another
before, another is only geared to map inputs to text strings. These are
If you ignore the level of detail (the functional substitution level) and
look at only the highest level of output, then you wouldn't up equating

It seems to me that the real issue is that perhaps you have been
misunderstanding what functionalism is this whole time. Yes a person asked
what 2+3 is and a calculated what 2+3 is will both give 5, but they are
very different functions when analyzed at a finer grain. This is what I
have referred to as the "substitution level", for humans it may be the
molecular, proteins, neural, or perhaps slightly above the neuronal level,
it is hard to say, and impossible to prove.
Note this is not done pet theory of mind, look at how Chalmers defines his
notion of functionally invariant:
"Specifically, I defend a principle of organizational invariance, holding
that experience is invariant across systems with the same fine-grained
functional organization. More precisely, the principle states that given
any system that has conscious experiences, then any system that has the
same functional organization at a fine enough grain will have qualitatively
identical conscious experiences. A full specification of a system's
fine-grained functional organization will fully determine any conscious
experiences that arise."
Note his repeated (I see three) appeals to it being a necessarily
"fine-grained" level of functional organization. You can't stop at the top
layer of them all saying "I see red" and call it a day, nor say they are
functionally equivalent if you ignore what's going on "under the hood".
Why do functionalists never talk about redness,
They do talk about redness and colors all the time. Chalmers fading qualia
experiment is entirely based on color qualia.
but just "functional organisation?
Because functional organization is the only thing that determines behavior,
and it is as far as we can test or analyze a system objectively.

It's not functionally isomorphic at a fine-grained level.
it can simulate the other 3,
It's not simulating the other three, it just happens to have the same
output. To be simulating one of the other three, in my view, it's circuits
would have to be functionally isomorphic to one of the others brains at
perhaps the neuronal or molecular level.
Note there is no way to simulate all three at the necessary level of detail
at the same time in your picture because they have different qualia. Should
two different fine-grained versions have different qualia implies, that
they are not functionally isomorphic at the necessary substitution level
(i.e. they're not the same at the fined-grained level on which the qualia

Different from what?

I think you may be missing some points regarding functionalism, and implore
you to read all of the dancing qualia thought experiment -- and consider
what the consequences would be *if we could* simulate the brain's behavior
using an artificial substrate.
I know you disagree with this premise, but if you truly want to understand
the functionalist perspective, you must temporarily accept the premise for
the purposes of following the thought experiment ans seeing where lead *if*
digital emulation were possible.

I mention colors and qualia all the time. And moreover I have provided many
arguments for why they are neither communicable nor shareable. Therefore I
see little point in me talking about "redness for me" because others who
are not me (everyone else on this list) cannot know what "redness for me"
is, or whether or to what extent it mirrors or approximates "redness for
It may be that the best we can do is say if we have two functionally
isomorphic versions of me, with identically organized brains, then the
redness for both will be the same, if the functional organization is
identical at the necessary functional substitution level (i.e., it is
