Yeah, but you can say that about "consciousness" itself. The topic is
wandering off into the mist a bit here, but I do believe that the "I" in me
is an illusion; I'm not really there. It's the only way I seem to be able
to explain away reality. Not very satisfactory, I know, but until someone
offers me something better ...

Obvious question: why do you think we are any different?

Yeah, but this misses the point. There IS feedback in the form of
selection. If Deep Blue makes bad moves, IBM will trash it. There doesn't
have to be anything in the code. It's the same feedback (and the only
feedback) that our own evolutionary path had until very recently.
Forget the physical substrate, and think only of the whole logical system:
inputs and ouputs. If one system produces all the same outputs for a given
series of inputs as another, then the systems are identical. If they don't
consist of the same stuff, that doesn't stop the SYSTEMs being identical.
One could be plastic, silicon and Cobol whilst the other is water, fat and
DNA.
A fun discussion this. :o)

Right. Whereas in humans, the internal difference between pleasure and pain
is ... er, what is the internal difference in humans exactly?

Hmm, that's a good point. But it is possible that this may have more to do
with our level of understanding of the system rather than the depth of the
distinction.

Although

Again, I think that this misses the point. I argue that if humans alter a
system in a way which leads to greater levels of reproduction for that
system, then the system has evolved. The agent causing the evolution is
irrelevant. The code doesn't have to learn from its mistakes in chess.
There merely has to be an environment which prefers good moves, with
penalties and rewards that affect reproductive success.

It doesn't have to be.

I guess we'd have to ask it. How can you tell if I am angry?

Precisely. You are interested only in your own emotions. That's all you can
be. In fact, you ought (I don't mean this nastily at all, but
scientifically) to be interested in only yourself, because you can't be
sure that anything else exists. There are two types of entity: you, and
everything else. Other humans, dogs, wasps and computer programs are all
"everything else", and you really can't say very much about them. Your own
body probably falls into the category of "everything else", too, which is a
bit unnerving.
What do you think?
