I understand why you think he would behave as if everything were fine, but you don't understand that I know why this view is reductionist fantasy. Everything that we do and are is an expression of every experience we have ever had. The way we reason is the result of the experiences which we have lived through. Although these experiences play a role in circumscribing the behavior of the neurology, you can't reverse engineer the experiences from the behavior. It's like assuming that you can excise a block out of New York City and replace it with something that you assume to be functionally identical. There is nothing that is functionally identical to a specific block of New York City. You can replace a building here or there and in time the population will embrace it, but the more of the city is replaced, the less able the population is able to assimilate the loss and the whole thing fails. He would *not* behave as if everything were fine because he would not be able to integrate new experiences as a human being would. As with all computing devices, there would be glitches that would be dead giveaways, and they would only become more prominent over time. > Do you understand why he > would internally and impotently notice that his experiences were > disappearing or changing? > I understand why you might believe that, but it's again based on a reductionist fantasy of consciousness. Do you think that someone with dementia is fully aware of their condition at all times like some kind of detached voyeur? If someone is falling down drunk are they internally and impotently noticing that their experiences are disappearing or changing? Consciousness isn't like that. It is a vast library of intertwined modalities of apocatastatic-gestalt frames of awareness access. It's not like you can stand aloof from your own psyche being dismantled...there isn't going to be enough of 'you' left to do that. Every part of your brain being replaced has to be compensated for by a live part of your brain picking up the slack, using the devices as prosthetic limbs and antennae. There is only so much that can be amputated and beyond that is irrevocable loss. > > If you try to build a person from mechanisms, you will *always fail*, > > because the sub-personal experiences are not accessible without the > personal > > experiences to begin with.

If you can't correct the optical problem though, they are not going to be able to see even if you rewire the visual cortex. This is what you are not understanding. Without the optical experience, there is no images in the brain. Nothing that you can do to the brain will generate a visual experience. > This is trivially obvious to me and most people: you > can't see because your brain doesn't work, and if you fixed the brain > you would be able to see. It seems trivially obvious to you because you don't understand the reality of perception. The brain, the eye, and illuminated conditions in the environment are all absolute requirements for the experience of visual sense to occur. None of those things can be missing, even with a perfect replica of a sighted person's brain. You assume that the brain contains experiences, but I don't. The brain only gives us access for perception and participation experiences as a human being. It can't generate experiences that it hasn't had. > But I'm guessing that you might say that > even if the blind person's eyes and brain were fixed, so that > everything seemed to work perfectly well, they would still be blind, > If their eyes worked then the neuroplasticity of the brain would adapt and hopefully begin to see eventually, depending on how long they had lived without sight. If the brain were fixed too, then they would learn to see very quickly, but still it would take months to get used to I would imagine. Pure speculation of course. But you think that what, you can pop on the eyes and visual cortex of a 40 year old Chinese man onto a Hungarian baby and he will be able to read Chinese? because the non-mechanistic non-reducible spirit of visual essence > would be missing. > Whenever anyone accuses me of talking about spirit or magic I know that they don't understand anything that I am talking about. Here is my post yesterday which specifically asserts why terms like spirit and soul are inappropriate. http://s33light.org/post/32628731508 Essence I do use but not in the way that you accuse me of. I use essence only in juxtaposition to existence, as a way of discerning between primordially direct experience (essence) and indirect representations of experience (existence). I would never say that there was a visual essence or any such vague allusion. I am about describing the ordinary conditions of experience as they really, even it it often requires pretentious words. I propose no supernatural or metaphysical properties, especially none that make mechanistic mathematical functions suddenly start feeling like they want to sing and dance.
