How can it really be said to be computational though? 2+2 =

It's not a feeling that comp isn't true, it's an understanding that
comp can't be causally efficacious. Computation can only inform those
who can be informed by it. To make something happen, information has
to be acted upon subjectively through sense and motive. Sense works on
multiple levels though, so that we can cajole a computer into opening
and closing logic gates which seem meaningful to us, but have no
larger coherence to the computer itself.

I don't think that comp can ask for that. Even within a program, you
can't have a GOTO "leap of faith". It is only we who can ask or offer
a leap of faith. Computers need to know. Since they don't know where
they've been and they don't know who they are, they have nothing to
invest in such a leap. If it could then we could beg our ATM that we
lost our wallet and it could agree to help us out.

Because I understand what a machine is and what I am. I am the
inherent interior experience of an organically evolved animal. A
machine is an idea which is enacted artificially on a comparatively
inert assembly of components. The continuity of the two is figurative,
not literal, so that even though a DVD player plays a movie, it is not
watching and enjoying the movie. Nothing in the room, not the TV, the
stereo, the furniture, even the cat, can understand the movie except
me. This is the symbol grounding problem. Puppets, not zombies. Some
things, like a fire, can be experienced by everything in the room.
Some things, like a piece of fish on a plate or a flea bite, can be
experienced by the cat as well as me, but nothing else.

Once that makes sense, there is no temptation to take comp seriously
anymore. A puppet can act like a cat as far as I'm concerned, but it
need not feel like a cat at all. Blindsight and synesthesia help us
know this clearly. Experiences for machines are not automatically
required, nor are they forthcoming just because we expect them to in
our own experience.

There are so many things we have gone over - how children learn
gestures and colors before math, how no disembodied machines appear in
space or haunting the internet, how machines have intuitively been
associated with being unconscious and unfeeling (mechanical, robotic),
how computers don't work unless they are constructed from certain
kinds of controllable solid objects, etc. I've made lists like these
on several occasions. The bottom line is that comp is unfalsifiable
logically, but not sensibly. There isn't any common sense experience
which supports the idea that computation can take initiative and
experience feelings like a living organism can.

I keep repeating this list, adding more each time. What else can I do.
Comp cannot disprove itself, so if you are looking for that to happen
then I can tell you already that it won't. I can't prove the existence
of color on a black and white TV alone. To prove color exists you have
to look away from the TV and see the world with your own eyes.

>Then such feeling are already explainable by machine

This is the black and white idea of a feeling - function (x) which
produces 'belief' (y) which expresses as behavior (k). It's all 3p
speculation. There is no belief, only logical constraint. No feeling,
only inferred involuntary probabilistic game theory.

That's because they have no sense. There's really no point in talking
about 'them' since every machine responds the same way. All machines
are a single 'it', just as all black and white TVs share in common
their lack of color.
