Such computer personas will probably be very different in terms of information 
storage and processing  - although we may not know it when they are developed 
simply because we still won't know how humans do it.  But a good example would 
be a neural net vice a production system.  At some level I'm sure you can get 
the same behavior out of them, but at the information processing level they're 
very different.

Incidentally, I wonder if anybody remembers that the test Turing proposed was 
for an AI and a man to each try to fool an interrogator by pretending to be a 
woman.

I basically agree, but with qualifications. If the attempt to copy human 
intelligence is "bottom up", for example by emulating neurons with electronics, 
then I think it is a good bet that if it behaves like a human and is based on 
the same principles as the human brain, it probably has the same types of 
conscious experiences as a human. But long before we are able to build such 
artificial brains, we will probably have the equivalent of characters in 
advanced computer games designed to pass the Turing Test using technology 
nothing like a biological brain. If such a computer program is conscious at all 
I would certainly not bet that it was conscious in the same way as a human is 
conscious, just because it is able to fool us into thinking it is human.

It might be because we're so visual and hence locate ourself at the viewpoint 
of our vision (but that wouldn't explain the Greeks).  Or it might be because 
we've been taught that consciousness is done by the brain.

I don't feel very pointlike. Rather my consciousness feels distributed over
a volume that is usually a substantial fraction of my brain. When
meditating my consciousness feels like it expands to fill the room or
maybe even larger.

What of it? Probably not significant

The tape recorder/ CD player example was to show that two entities may have 
similar behaviour generated by completely different mechanisms. As you say, we 
can see the brain, we can see the behaviour, but we *deduce* the consciousness, 
unless it is our own. If someone has similar behaviour generated by a similar 
brain, then you would have to invoke magical processes to explain why he would 
not also have similar consciousness. But if someone has similar behaviour with 
a very different brain, I don't think there is anything in the laws of nature 
which says that he has to have the same consciousness, even if you say that he 
must have *some* sort of consciousness.

That's just what our brains make us think. If our brains were slightly 
different our consciousness could seem to be located in our big toe, or on the 
moons of Jupiter.

Here's my reasoning: We think other people (and animals) are conscious, have 
experiences, mainly because of the way they behave and to a lesser degree 
because they are like us in appearance and structure.  On the other hand we're 
pretty sure that consciousness requires a high degree of complexity, something 
supported by our theories and technology of information.  So we don't think 
that individual molecules or neurons are conscious - it must be something about 
how a large number of subsystems interact.  This implies that any one subsystem 
could be replaced by a functionally similar one, e.g. silicon "neuron", and not 
change consciousness.  So our theory is that it is not technology in the sense 
of digital vs analog, but in some functional information processing sense.

So given two things that have the same behavior, the default assumption is they 
have the same consciousness (i.e. little or none in the case of CD and tape 
players).  If I look into them deeper and find they use different technologies, 
that doesn't do much to change my opinion - it's like a silicon neuron vs a 
biochemical one.  If I find the flow and storage of information is different, 
e.g. one throws away more information than the other, or one adds randomness, 
then I'd say that was evidence for different consciousness.

The word" theology" again (was Hypostases (was: Natural Order & Belief)

2006-12-06 Thread Bruno Marchal

Hi Brent,

Our present discussion with Tom and others is particularly important 
for me. I am concentrating myself on the last decisions before writing 
"the english version of my thesis", probably in the form of one paper + 
one book (the difference is that the book should be an, as 
self-contained as possible, version of the paper. It is difficult 
because the intended audience is fuzzy: physicists have the right 
motivations (figure out what is reality), logicians and computer 
scientists have the right tools (diagonalizations), neoplatonist 
theologians have the right attitude, basic theory and questions, etc.

I still don't know if you have understand the full UDA reasoning, or at 
least the seven first steps, nor do I know if this would help 
concerning the "vocabulary" problem. I do think you have not yet 
understand the AUDA, as your recurrent remark on Gettier 
illustrateswe should perhaps harness this point in a deeper way at 
some point.
A contingent problem is that physicists, who are the best placed to 
understand my work, has been cooled down by the fact that someone as 
brilliant in math as Penrose has been able to be so wrong on Godel's 
theorem, and for many people the term "Godel" means "risky"!

Now, since I have defended my thesis, I have done two "major" 
discoveries (as people following the list can guess):
1) The interview of the lobian machine directly offers a purely 
arithmetical interpretation of Plotinus's theory (of mind&matter).
2) The comp standard model of particles can be derived from some 
permutations group related to universal diophantine polynomial. This 
has forced me to dig far deeper in number theory, and leads, here too 
alas, toward very complex mathematical questions.

In my mind, the "1)" really helps, as far as we are open to 
neoplatonism. If not, it obviously favorizes rejection. The "2)" does 
not help at all and I don't know really what to do with that.

That is the idea, but actually I never use the term "God", except for 
going quick in some answer to post which use the term. The "God" I 
refer to is closer to Plotinus' ONE or to the Chinese TAO, the main 
axiom is that it is the biggest unconceivable reality with the property 
that you cannot give a name to it, or if you do, you get a 
multiplication of approximations which can hide the very idea (but 
which can be rich and creative though when distinguished from It).
The arithmetical interpretation of the ONE for the "theology" of a 
lobian machine PA is arithmetical truth. By Tarski theorem it is 
unameable by PA, for example.

Hard question of course, but a case can be made that it would have been 
accepted by the most pythagoreans among the neoplatonist.

The neoplatonist have introduced it, but Plotinus ascribes it to the 
Parmenides of Plato. The Timaeus and other text by Plato and even 
Aristotle are going in that direction. Note that the neoplatonist are 
rationalist, and their use of words is very near the modern axiomatic 
like the one used in math. In some late neoplatonist works "Gods" can 
be translated by the concept of concept, property, or even set. But 
Plotinus endows monotheism/monism, as I think comp, by its unameable 
platonism, does too.

Deism, pantheism, naturalism are all "theological" position. This is 
perhaps why I need the term "theology", in an admittedly larger sense 
than the current sense. The UD reasoning shows that the belief in 
naturalism is a theological position. It need faith in something called 
"Nature", etc. I really consider scientific theology as the scientific 
approach to what science cannot prove, but still infer correctly. Of 
course I would less dare to say this without knowing about the [] and 
[]* distinction in the arithmetical hypostases (G*/G, Z1*/Z1, X1*/X1, 
etc.)

Yes. Even to conclude perhaps that there is no evidence known for

A tape recorder or a CD has no external behavior that would mimic a human. But 
I really think that if you have same external behavior than a human then 
the "copy" (whathever it is made of) will be conscious. Exact replica means 
you can talk with the replica, learn, etc... It's not just sound (and or 
move). Even If I knew that the "brain" copy was made of smashed apples it 
would not change my "mind" ;) about it. The only "evidence" of others 
consciousness is behavior, social interactions, ... You could scan a brain,

physical (and chemicals which is also "physical") activities of the brain, 
yet I feel my consciousness (in fact me) is located in the upper front of my 
skull... Why then neurons located in the back of my brain do not generate 
conscious feeling ? And if they do participate, why am I located in the front 
of my brain ? Why this location ? Why only a tiny part of the brain feels 
conscious activities ?

You're implying that the default assumption should be that consciousness 
correlates more closely with external behaviour than with internal activity 
generating the behaviour: the tape recorder should reason that as the CD player 
produces the same audio output as I do, most likely it has the same experiences 
as I do. But why shouldn't the tape recorder reason: even though the CD player 
produces the same output as I do, it does so using completely different 
technology, so it most likely has completely different experiences to my own.
