If you built a kidney-dialysis machine by a 1:1 mapping and forgot some cell type that is causally active in kidneys, the machine would not actually work.#
I arguing about cases ofWEB and neurla replacement, which are stiuplated as not being 1:1 atom-for-atom replacements.
Changing the physical substrate could remove the qualia, but to claim it could remove the qualia while keeping talk of qualia alive, by sheer coincidence
Not coincidence: a further stipulation that funcitonal equivalene is preserved in WBE;s.
Are you proposing that it’s impossible to build a straight neuron substitute that talks of qualia, without engineering purposeful qualia-talk-emulation machinery?
I am noting thar equivlant talk must be included in functional equivalence.
Why not just build a regular qualia engine, by copying the meat-brain processes 1:1?
You mean atom-by-atom? But is has been put to me that you only need synapse-by-synapse copies. That is what I am responding to.
Okay. I don’t think it’s possible to build a functional equivalent of a mind that talks of qualia because it has them, by 1:1 porting at the synapse level, and get something that talks of qualia without having any. You can stipulate that all day but I don’t think it can actually be done. This is contingent on neurons being the computational elements of our minds. If it turns out that most of the computation of mindstates is done by some sort of significantly lower-scale process and synaptic connections are, if not coincidental, then at least not the primary element of the computation going on in our heads, I could imagine a neural-level functional equivalent that talked of qualia while running the sort of elaborate non-emulation described in my previous comment.
But if neurons are the computational basis of our minds, and you did a 1:1 synapse-level identical functional copy, and it talked of qualia, it would strain credulty to say it talked of qualia for a different reason than the original did, while implementing the same computation. If you traced the neural impulses backwards all the way to the sensory input that caused the utterance, and verified that the neurons computed the same function in both systems, then what’s there left to differentiate them? Do you think your talk of qualia is not caused by a computation in your neurons? Qualia are the things that make us talk about qualia, or else the word is meaningless. To say that the equivalent, different-substrate system talked about qualia out of the same computational processes (at neuron level), but for different, incorrect reasons—that, to me, is either Chalmers-style dualism or some perversion of language that carries no practical value.
