"If you think about your own vision, you can see millions of

them as single bit's so in reality the can't be conscious of a
full picture, not even of the full color at a single pixel.
He is making the same mistake Searle did regarding the Chinese
room. He is conflating what the CPU can see at one time
(analogous to rule follower in Chinese room) with what the
program can know. Consider the program of a neural network: it
can be processed by a sequentially operating CPU processing one
connection at a time, but the simulated network itself can see
any arbitrary number of inputs at once.
How do he propose OCR software can recognize letters if it can
only see a single pixel at a time?
Who says OCR software can recognize letters? All that it needs
to do is execute some algorithm sequentially and blindly against
a table of expected values. There need not be any recognition of
the character as a character at at all, let alone any "seeing".
A program could convert a Word document into an input file for
an OCR program without there ever being any optical activity -
no camera, no screen caps, no monitor or printer at all.
Completely in the dark, the bits of the Word file could be
converted into the bits of an emulated optical scan, and presto,
invisible optics.
Searle wasn't wrong. The whole point of the Chinese Room is to
point out that computation is a disconnected, anesthetic
function which is accomplished with no need for understanding of
larger contexts.
Searle might be right on non-comp, but his argument has been
shown invalid by many.
I'm surprised that you would try to pass that off as truth Bruno.
You have so much tolerance for doubt and uncertainty, yet you
claim that it "has been shown invalid". In whose opinion?
It is not an opinion, it is a fact that you can verify if patient
enough. The refutation is already in Dennet and Hofstadter "Mind's
I " book. Searle concludes that the man in the room is not
understanding chinese, and that is right, but that can not refute
comp, as the man in the room plays the role of a CPU, and not of
the high level program on which the consciousness of the chinese
guy supervene. It is a simple confusion of level.
The high level program is just a case-by-case syntactic handler
though. It's not high level, it's just a big lookup table. There
is no confusion of level. Neither the Chinese Room as whole, the
book, nor the guy passing messages and reading the book understand
Chinese at all. The person who understood Chinese and wrote the
book is dead.
The kind of reasoning that you (and Dennett and Hofstadter) are
using would say that someone who is color blind is not impaired if
they memorize the answers to a color vision test. If I can retake
the test as many times as I want, and I can know which answers I
get wrong, I don't even need to cheat or get lucky. I can compute
the correct answers as if I could see color in spite of my
complete color blindness.
What you are saying is circular. You assume that the Chinese guy
who wrote the book is running on a program, but if you knew that
was the case, then there would be no point in the thought
experiment. You don't know that at all though, and the Chinese
Room shows why computation need only be performed on one level and
never leads to understanding on any others.
I am not sure I can help you. You confuse the levels. You don't
really try to understand the point, which would mean that you talk
like if you knew that comp is false.
I don't expect you to help me, I'm trying to help you.
Of course. But what helps me is reasoning, not personal conviction.
Consciousness cannot be accessed by reasoning, since reason is an
experience within human consciousness.
You are entirely right on this.
But to communicate with others, even on consciousness, or on line and
points, or galaxies or gods, we can only agree on principles and
reason from that.
I don't know that comp is false, but I know that if it isn't it
won't be because of the reasons you are suggesting. Comp may be
true in theory, but none of the replies to the Chinese room are
adequate, or even mildly compelling to me.
Searles confuse a program, and a universal program running that
program.
Aren't universal programs made of programs? It sounds like you are
importing the Explanatory Gap into computation.
A universal program is a program. it is made of instructions, or code
like any program. I identify it with its number in a universal
enumeration phi_i. It is a u such that phi_u(x,y) = phi_x(y). u is the
universal program, x is the program, and y is the data. Those
relatioon can be defined in term of 0, s(x), + and *.
This page http://plato.stanford.edu/entries/chinese-room/ is
quite thorough, and lists the most well known Replies, yet it
concludes:
"There continues to be significant disagreement about what
processes create meaning, understanding, and consciousness, as
well as what can be proven a priori by thought experiments."
Thought experience are like proofs in math. Some are valid, some
are not valid, some are fatally not valid, some can be corrected
or made more precise. The debate often focuse on the truth of comp
and non-comp, and that involves sometimes opinion. I don't really
play that game.
Game? All it's saying is that there is no consensus as you claim.
The fact that you claim a consensus to me smells like a major
insecurity. Very much a 'pay no attention to the man behind the
curtain' response.
Without that consensus, there would be no scientific researches nor
beliefs. The consensus is not on truth in general, but on the means
of communication. Your answer betrays that yo have more a pseudo-
religious agenda than an inquiry in what could possibly be true or
false.
My agenda is to understand consciousness as it actually is, rather
than as a theory would like it to be.
Understanding is always in the frame of some assumption. You confuse
the experience, and the possible explanation for the existence of
that experience (which is indeed more direct, but that can be due to
the existence of the brain).\
I'm really not confused at all. Explanations are experiences too.
Existence is an experience. There can be nothing other than
experiences.
There are the experiences of others, and what might relate yours to
the one of the others.
The replies listed are not at all impressive to me, and are all
really variations on the same sophistry. Obviously there is a
difference between understanding a conversation and simply
copying a conversation in another language. There is a difference
between painting a masterpiece and doing a paint by numbers or
spraypainting through a stencil. This is what computers and
machines are for - to free us from having to work and think
ourselves. If the machine had to think and feel that it was
working like a person does, then it would want servants also.
Machines don't want servants though, because they don't know that
they are working, and they function without having to think or
exert effort.
And this is begging the question.
Only if you are already assuming Comp is true from the start.
Not at all. It is rare I do not assume comp, though, but here I was
not.
Our position are not symmetrical. I suggest a theory and reason
from there. You pretend knowing a truth, and use this as a pretext
for not looking at a theory. I doubt the condition for a dialog is
possible.
I'm not pretending to know a truth, I am stating that I understand
the point that Searle and Leibniz made, and which the replies to
that point do not. They underestimate the depth of consciousness,
and mistake copy and pasting Shakespeare for being Shakespeare.
But here you betray that you are again begging the question. What
you say is just "no doctor". So you introduce either an infinite low
level of comp (= non comp), or something non turing emulable in the
brain or the body.
No, I am challenging the entire frame of quantitative reference. It
has no authority over qualitative, aesthetic phenomena.
Both are needed, but you can't communicate what is not communicable.
I am saying that numbers are always derived from aesthetic
experience - either bodies in public space or experiences in private
time, but that no aesthetic experience can ever be generated by
numbers alone.
Numbers are simpler to assume than aesthetic experience, which might
be "just" the 1p-experience of machine.
You assume the complex to explain the simple.
The consequences then, of trying to generate aesthetic experience by
reverse engineering it from its footprints in public space and the
narrow awareness-of-awareness of our human privacy, is the uncanny
valley - impersonated presence. This of course is precisely what we
have observed in every instance where AI has been implemented. No
device is born as a baby is, giving and receiving emotion and
sensation.
Creatures can appear in many ways.
It's not a matter of the brain not being emulable, it is a matter of
the activity of the brain being partially driven by something which
is not emulable in any way, because it is by definition a genuine
and utterly unique event in the universe.
This looks like wishful thinking.
We might be relatively unique, but the evidences are that we are not
unique, at many different levels.
