What does "partly as an abstract formal description of its former
reality" mean? It certainly could be taken as incoherent nonsense. I
asked you no such thing. I asked what would happen if a surgeon
installed in your brain artificial neurons which were designed so that
they perform the same function as biological neurons. You agreed that
it is possible to make such neurons, and you agreed that they could be
installed. These are easily understandable, concrete concepts. Such
procedures might even become commonplace in a few years time, as
treatment for patients who have had strokes or head injuries.
Naturally, the patients would be observed after the procedure and they
would either behave normally and say that they felt normal, or they
would not. It's perfectly straightforward, and the whole experiment
from start to finish could be done by technicians with no idea about
philosophy of mind. Your insistence that it's nonsense suggests that
you have such a strong attachment to your position that you don't want
to face any argument that you can see would challenge it.
