How would someone know that they don't have subjective experience? Someone who is color blind can tell that they don't see, for example, blue because they are told by someone who does see blue that a distinction exists that they don't perceive. It's hard to come up with such a distinction for subjective experience as a whole. But how about this. Nick, when you "see" a color, such as blue do you know that it's blue because you explicitly compare numeric pixel values to a table that tells you it is blue, or is your experience of blue a direct experience?

It's
one thing to say (and I agree) that we have no idea how any of us can
experience any one else's subjective experience. (Perhaps we will be
able go do it at some point, but we can't now.)
It's another thing for someone to say that they don't have
subjective experience. It's hard even to imagine what that means. If
one doesn't have subjective experience (as, in my opinion, computers
don't) it's not clear what such a being would mean by denying having
subjective experience--since they don't know what it means.
It's also hard for me to believe Nick (or Hans) when they say that
they don't have it. I don't know how far down it goes, but most (at
least) higher level biological organisms seem to have subjective
experience.
Furthermore, I'd say that subjective experience is all that
we have. All any of us has is his/her own subjective experience. That's
where we live--in our subjective experience. There's no way to avoid it
-- even if one meditates. (It's still subjective experience that one is
experiencing in that state too; it's just not conceptualization.) So
for a human being to deny having subjecctive experience simply doesn't
make sense to me since I can't believe that any human being doesn't
have it. -- Russ Abbott _____________________________________________ Professor, Computer Science California State University, Los Angeles o Check out my blog at http://bluecatblog.wordpress.com/

Russ,
What you say
(ask) resonates with me. In the early 1980’s when he and I were
junior faculty in the Robotics Institute at Carnegie Mellon (he was slightly
senior to me), Hans Moravec and I would have a very similar argument for hours
and frequently. I finally invited him to an AI class I was teaching to
have a public version of the discussion. Our basic positions were characterized
by:
Frank: My
subjective experience of consciousness is the first thing I know and the thing
I know exists with complete certainty (cf. Descartes. Sorry, Nick).
Hans: That’s
an epiphenomenon. It’s just one part of your brain observing another
part of your brain.
Anyway, I
eventually said to him, “Hans I understand the difference in our points
of view. You don’t have it! That’s why you don’t
get what I’m saying.”
I actually don’t
believe that Hans (or Nick) don’t have it.

Hi Nick,
I don't think I understand your position. Are you talking about subjective
experience?
It seems to me that the essence of the "problem of consciousness,"
what Chalmers calls "the hard problem," is subjective experience,
i.e., the first person perspective. We all have it. (Or do you deny that you
have it?) But we have no idea how to explain it or to understand what it is or
how it comes about. That seems to me to be the heart of the problem. Are you
focusing on that issue (and if so what is your position) or on something else?

John,
John,
All good questions.
I dont think I make a distinction between precise statements and metaphors.
I think I think it's metaphors all the way down
I also I think I think there is no such thing as a first person perspective
... not really. Specting.... seeing the world from a position ... is what
every creature does. One of the events that I can spect, is a creature
specting its world, and one of the creatures that I can spect, in this way
, is myself. Not my inner processes or my mind, but me, an actor in the
world.
Like all observers, I am situated, and since I am the only person who is
around me all the time, I am situated in a particularly unique way with
respect to myself. My situation may sight me or blind me, depending on
the
kind of information that is required to make an accurate prediction about
what I will do.
Those are my best answers.

a scientific theory of consciousness, it must be based on a third person
approach. But it seems possible that there are some facts about 'the
world
as it really is' that are not now accessible to science. If this is so, the
impressions we receive from the first-person point of view may offer us the
best insights we can get, given the current state of scientific knowledge.
So why must we rigorously ignore such impressions?

consistent. Trying to use precise language about our minds may be as
difficult as creating a scientific theory of our 'inner lives'. Maybe when
discussing this area, we can only use language metaphorically and hope that
the person we are communicating with can make sense of it. What about your
statements that 'consciousness is an illusion' or a 'huge language game' .
Are these metaphors or precise statements?
