These words are a scientific evidence of this. The atoms of my brain are being manipulated from the top down. I am directly projecting what I want to say through my mind in such a way that the atoms of my brain facilitate changes in the tissues of my body. Fingers move. Keys click. > Evidence would > constitute, for example, neurons firing when measurements of > transmembrane potentials, ion concentrations etc. suggest that they > should not. Do not neurons fire when I decide to type? What you are expecting would be nothing but another homunculus. If there was some special sauce oozing out of your neurons which looked like...what? pictures of me moving my fingers? How would that explain how I am inside those pictures. The problem is that you are committed to the realism of cells and neurons over thoughts and feelings - even when we understand that our idea of neurons are themselves only thoughts and feelings. This isn't a minor glitch, it is The Grand Canyon. What has to be done is to realize that thoughts and feelings cannot be made out of forms and functions, but rather forms and functions are what thoughts and feelings look like from an exterior, impersonal perspective. The thoughts and feelings are the full-spectrum phenomenon, the forms and functions a narrow band of that spectrum. The narrowness of that band is what maximizes the universality of it. Physics is looking a slice of experience across all phenomena, effectively amputating all of the meaning and perceptual inertia which has accumulated orthogonally to that slice. This is the looong way around when it comes to consciousness as consciousness is all about the longitudinal history of experience, not the spatial-exterior mechanics of the moment. > You claim that such anomalous behaviour of neurons and > other cells due to consciousness is widespread, yet it has never been > experimentally observed. Why? > Nobody except you and John Clark are suggesting any anomalous behavior. This is your blind spot. I don't know if you can see beyond. I am not optimistic. If there were any anomalous behavior of neurons, they would STILL require another meta-level of anomalous behaviors to explain them. Whatever level of description you choose for human consciousness - the brain, the body, the extended body, CNS, neurons, molecules, atoms, quanta... it DOESN'T MATTER AT ALL to the hard problem. There is still NO WAY for us to be inside of those descriptions, and even if there were, there is no conceivable purpose for 'our' being there in the first place. This isn't a cause for despair or giving up, it is a triumph of insight. It is to see that the world is round if you are far away from it, but flat if you are on the surface. You keep trying to say that if the world were round you would see anomalous dips and valleys where the Earth begins to curve. You are not getting it. Reality is exactly what it seems to be, and it is many other things as well. Just because our understanding brings us sophisticated views of what we are from the outside in does not in any way validate the supremacy of the realism which we rely on from the inside out to even make sense of science. > > >> If the atoms in my brain were put into a Chinese-reading configuration, > >> either through a lot of work learning the language or through direct > >> manipulation, then I would be able to understand Chinese. > > > > > > It's understandable to assume that, but no I don't think it's like that. > You > > can't transplant a language into a brain instantaneously because there > is no > > personal history of association.

It's like saying you will put New York City directly in the same configuration as Shanghai. It's meaningless. Even if you could move the population of Shanghai to New York or demolish New York and rebuild it in the shape of Shanghai, it wouldn't matter because consciousness develops through time.

Then the thought experiment is garbage from the start. It begs the question. Why not just say we can have an imitation human being that stimulates the surrounding human beings in the same way as the original? Ta-da! That makes it easy. Now all we need to do is make a human being that stimulates their social matrix in the same way as the original and we have perfect AI without messing with neurons or brains at all. Just make a whole person out of person stuff - like as a thought experiment suppose there is some stuff X which makes things that human beings think is another human being. Like marzipan. We can put the right pheromones in it and dress it up nice, and according to the thought experiment, let's say that works. You aren't allowed to deny this because then you don't understand the thought experiment, see? Don't you get it? You have to accept this flawed pretext to have a discussion that I will engage in now. See how it works? Now we can talk for six or eight months about how human marzipan is inevitable because it wouldn't make sense if you replaced a city gradually with marzipan people that New York would gradually fade into less of a New York or that New York becomes suddenly absent.

Neither. The whole premise is garbage because both Brooklyn and brain are made of living organisms who are aware of their description of the universe. We can't imitate their description of the universe because we can only get our own description of our measuring instruments description of their exterior descriptions. > >> The original paper says this is a computer chip but this is not > necessary > >> to make the point: we could just say that it is any device, not being > the > >> normal biological neurons.

The implant can't work as a source of consciousness on a personal level, only as band-aid on a sub-personal level. Making a person out of band-aids doesn't work.
