Yes, but you decide to type because neurons fire.

Craig, I have repeatedly explained how entertaining your hypothesis that consciousness is substrate-dependent rather than function-dependent, which on the face of it is not unreasonable, leads to absurdity.

If the the behaviour of neurons cannot be described and predicted using physical laws then there must be anomalous at play.

Well, if you did disassemble New York and put the atoms into Shanghai's configuration, including the population, then you would have Shanghai.

The imitation human stimulating his surrounding humans in the same way as the original could be a zombie or a very good actor. That's what we need for the neural implant in the thought experiment: a zombie or a very good actor that stimulates the surrounding neurons in the same way as the original. Do you think this is logically impossible? Logical possibility is all that is needed in order to establish functionalism. > You aren't allowed to deny this because then you don't understand the > thought experiment, see? Don't you get it?

It's a fallacy. The premise > screws up the result. To state it as clearly as I can again, what is required is an artificial component that stimulates the other neurons in the same way as the original did. Chalmers says that this component is a computer chip, which is necessary to establish computationalism, but not to establish functionalism. To establish functionalism, it is not necessary to specify how the component works, only that it does work. >> We can even say >> that it does this miraculously.

Are you actually saying that it is *logically* impossible to replicate a neuron's behaviour stimulating its neighbours? Not just that the behaviour is not computable, but that not even an omnipotent being could replicate it? So where is the logical contradiction? >> As I said, technical problems with computers are not relevant to the >> argument.

But you said there are no scientifically anomalous events in neurons, and if so it would mean that the timing can be be calculated. And if that fails, there is always God, who is omnipotent. If God got the timing right would consciousness necessarily be preserved? If so, functionalism is established as true. If not, we would have the possibility of partial (as well as full) zombies, lacking aspects of their consciousness but unaware of this. -- Stathis Papaioannou -- You received this message because you are subscribed to the Google Groups "Everything List" group.
