First, I hope everybody has a merry christmas, but I think it's important to 

remember the true meaning of the holiday. Today is the birthday of our savior
from ignorance, Isaac Newton. We should also remember that GOD is the answer. 
The question, of course, is "How do you spell "DOG" backwards?".

I agree completely, it's totally irrelevant.

A machine couldn't tell you what the view outside a window is if
it didn't have that information, but then, neither could Hawking. 
People use  electro-chemical photon receptors called "eyes" to gain this 
sort of information. I see no reason why a machine couldn't do the same.

Absolutely, every one of those things is part of behavior.

Shitting and peeing are undoubtedly types of behavior, but they
are not the sort of behavior I use to gage the intelligence or
consciousness of my fellow man, so I see no reason to use them
in judging the intelligence or consciousness of a machine.

Turing  used text in his test because it was the simplest thing
that would get the job done. You can put in other things if you
want to, (the test will still work because a machine, in principle, 
can do anything a person can) but there is not much point in doing so, 
it would just complicate things without adding any precision to the test. 
The only reason I have sometimes done so is when others have brought up 
examples that they claim invalidated the test.

Perhaps you can do these things, but the only way I will ever know anything
about it is if you say so, or write it down, or engage in some sort of 
behavior.                     


                >I don't just sit and think. I write things down. [...] I am

I do the same thing, it's because our memory is so poor we can't remember 
even for a minute the few bits of information that are on the paper. 
A brain that lacked this limitation and did not need to scribble on paper 
could still be conscious, perhaps even more conscious than you or me.

I agree. He didn't include smell for example, because it's not relevant, 
he didn't include movement because it's a redundant complication handled by 
text more clearly.

Yes, it's not very deep, a platitude almost, that's why it surprises me when  
I get so much resistance when I just follow it to it's logical conclusion.

I'm almost certain that's true, and even if it did arise by chance, evolution  
wouldn't let us keep it for long unless consciousness helped us to survive, 
and the only way it could do that is by effecting our behavior. I've said it 
before I'll say it again, if evolution can "see" consciousness then so can

Not surprising, I don't see how you could have consciousness without emotion 
and I don't see how you could have intelligence without consciousness. 
                

                >just what do you mean PRECISELY by intelligence here? 
                  
I can't tell you, at least not precisely. I can give you lots of examples of 
things that are intelligent and things that are not, but I've never seen a 
definition that was better than mediocre. All I can say is that like a 
familiar face, I can recognize it when I see it, and that's just what you'd 
expect if, as I think, we're more like neural nets than expert systems. 
Neural nets aren't very good at definitions but are good at putting things in 
categories because they are "like that" or "not like that".
                   


                >If you want to talk about "intelligence" more broadly than
                
                >in comparisons among human beings, then you need a much
                                >better definition of what it is, applicable to ANYTHING. 
                 
I don't think we will ever find a good definition of intelligence, at least 
not one short enough to write on a piece of paper smaller than the galaxy. 
A definition of consciousness would be even more difficult. 

This doesn't mean we can't talk about these things however, because we have 
lots of examples of both things, examples I am sure we would both agree on, 
examples in which we have both independently put the same thing in the same 
category.

Thanks, my programmers are quit flattered by your kind words, as are my many  
beta testers who made sure that every last bug was completely eliminated

from my system from my system from my system from my system from my system 
from my system from my system from my system from my system from my system
