then the best it could be is: “A miracle happens here”. That alone (along with all the other
resulting “hard” problems) proves to me you’ve got a mistake somewhere in your
logic. And given how detailed I describe
the problem with this logic, I don’t understand how you can’t see this.</span></p>

A, B, and C is so far aware from any qualia, and what qualia are is completely irrelevant. As I’ve tried to point out repeatedly, you
not including the required functionality.
You’ve got to include the colorness functionality (redness, greenness…)
in the system,, and finally a binding mechanism which can computationally bind colorness
together, so you can have a composite qualitative experience composed of lots
of them.</span></p>

required binding functionality. You said
a and b could be “Chemical Signals.” We
can throw out b because that is causally way downstream from the qualia pixels elements
we can both objectively observe and consciously be directly aware of, would be
aware of, presenting to a binding system.
a must be whatever it is that is the colorness quale (redness, greenness….)
we can detect by being aware of its quality computationally bound to lots of
other pixels of colorness. I say colorness,
a, is a physical property, evidently you think a is just magic. And there must be more than just B(a). Since we can have at least 10s of thousands
of pixels of awareness for each pixel on a surface we can see. So it must be B(a1, a2, a3…. aN) Where n is at least tens of thousands of elemental
“magic” qualities which can be bound into one unified conscious experience by
B.</span></p>

B is the ability to recognize physical (or magic) red. If it is glutamate that has the redness
quality we can directly experience, B (and B1) must be able to report being
aware that anything but glutamate (or redness or magic) being presented to any aN
must be able to report, by being aware of that physical or qualitative (or
magic?) difference, that it is not glutamate.
If it can’t do that, then it isn’t functioning properly.</span></p>

kind of substitution from B to B1, you must be able to use B1, to bind to the
neuro substituted system, so you can be computationally aware of whether it is

are thinking of.)</span></p>

You can chop down a tree with an axe made of steel but "chopping down a tree" is not a physical property of the steel, it is a process that can also occur with an axe made of a different material, such as titanium or tungsten. This does not mean that "chopping down a tree" is magic!</div><div><br></div><div>With regard to my A, B, C system it is important to emphasise that the scientist can be COMPLETELY IGNORANT of any consciousness and still repair or replace its components, simply by observing its behaviour. I might not know anything about how a computer works or what a computer does, but I could still replace wiring in the computer by soldering in new wires, and I would expect that it would continue working the same. All I have to do is test the electrical properties of the wire, make sure the replacement has a similar resistance and is able to carry at least the same current, make sure it is insulated appropriately for the voltage, and so on. For completeness I could swap it in and out of circuit and make sure that the inputs and outputs are the same. With my example, all the scientist has to do is find a replacement B1 such that B1(a) = B(a) for all inputs a. He does not have to know anything whatsoever about qualia, binding or pixels. If he does this, the output of the system (speech, in this case) given a particular input MUST be the same. Do you disagree with this?</div><div><br></div></div>-- <br><div dir="ltr" class="gmail_signature">Stathis Papaioannou</div></div>
