In other words you are assuming glutamate is just some "component" of whatever it is that has redness. (Completely changing what it actually says). Thankfully, in the past, after a gazillion requests, you finally provided the "op amp" example. You pointed out that you can replace all the neurons performing the op amp functionality with neurons that can perform the same functionality, and it would still result in redness. You think I disagree with this, but I don't. You are just changing the conversion away from what I"m trying to talk about.

But there is no extra such effect; changing the shape of receptors that it binds to due to the electrostatic force is 100% of the relevant physical effect of every glutamate molecule in every human that has ever lived.</div></div></div></blockquote><div>More proof that you are completely misunderstanding what I"m trying to say. Again, in the case you are talking about, glutamate is only a "component". In that case I'm not talking about a "component" of redness, I'm talking about whatever is the necessary and sufficient set of physics that has the redness quality we directly experience for that one pixel.</div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr"><div class="gmail_quote"><div> </div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr"><div class="gmail_quote"><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr"><div class="gmail_quote"><div>This analysis can be continued for the whole brain, replacing every part with a different part, but preserving all the qualia and consciousness.

IF this is true, then the result is that nothing can have redness, for the same reason. It seems like you are completely ignoring that, and just going back and replaying the old steps that lead to the checkmate, without changing anything, yet expecting different results?</div></div></div></blockquote><div><br></div><div>I misunderstood the "checkmate". Was it that qualia are epiphenomenal? I don't consider that "checkmate".</div></div></div></blockquote><div><br></div><div>OH, yea. That was my bad. James Carroll, who is also a functionalist (the guy that joined the conversation on Quora the other day, he liking your "functionalists" responses, and hem adding additional functionalist responses.)</div><div><br></div><div>My recollection is that he would repeatedly say the neural substitution argument proves that if it is glutamate that has the redness quality, then redness must be "epiphenomenal", which we both agreed meant redness would not be approachable via science, and we both agreed that would be game over or something neither one of us could accept. Kind of ironic, in a way.</div><div><br></div><div>So, it was a big surprize to me to hear you say you believe qualia are epiphenomenal. But anyway, that doesn't matter. What I was talking about, was the second argument I was making that would also be a "check mate", especially in your case. (in James' case, I think I have a double check mate, but let's ignore that for now.)</div><div><br></div><div>So, back to the op amp being the necessary and sufficient set of functionality to experience a redness quality (including when you can achieve the same addition op amp with various diverse sets of "components") So, now, we need to replace glutamate, with this op amp (or whatever it is, including magic) that is the necessary and sufficient set of physics that have the redness quality you can experience for that one pixel. For the same reason you are claiming it can't be glutamate, you must also make the same claim for addition op amps. They can't have redness, absolutely nothing, even magic, can have redness, and you can prove that for anything that you try to substitute glutamate with.</div><div><br></div><div>With that I'm thinking: And we all know, more than anything, that we can experience redness. So if your so called "proof" "proves" we can't, there is something wrong with your proof.</div><div>That seems to me to be Checkmate.</div><div><br></div><div>Does that help at all?</div></div></div></blockquote><div><br></div><div>I wouldn't say it's hopeless for scientific study if qualia are epiphenomenal. We effectively study qualia by talking to people, and deducing from that what they are experiencing. We cannot be sure that other beings have qualia, but we can also be sure, as I have explained many times, that IF they have qualia, replicating just the objective behaviour will also replicate the qualia. Replicating the objective behaviour could be done in an indefinite number of ways, so there is no particular physics that is necessary for particular qualia.</div></div><div><br></div>-- <br><div dir="ltr">Stathis Papaioannou</div></div>
