Of course. You're always correct.
No, but more then you would like to think.
See. Always right. It's uncanny.
I see by trying to explain my logic for thinking a certain way is met by
some of your arrogance, I'll refrain from doing that in the future.
> How do you "know" it's a rainbow and not something else?
Got me.
Try real hard, I'm sure you'll come up with something. You always do.
Well, it probably wouldn't be the main focus of your attention. But you
_could_
see it. I just went out in front and tested it with a cloud (no rainbows
today). I fell down on the grass but still saw the cloud while I was
falling.
But maybe this only works for clouds so I'll just assume you're right as
always.
What a great experiment. You looked up at a cloud and surprised yourself by
falling down. Neat trick. I wonder what you were controlling for when you
were "falling".

If you say so.

What do you mean by "know"? The rainbow simply exists as a perception. If
by
"know" you mean " how are you able to say 'that's a rainbow'" I think
that's up
at the category level (for associative naming) and program level (for
carrying
out the process of naming naming it).
So your smart ass remark "If you say so" just above is out of line, isn't
it?

I can understand that it would not be easy or clear to a lay person. I
studied
perception for years before I got involved in PCT and I know that my
brain was
doing some somersaults in graduate school, certainly when I started in the
field. Perception is not an easy thing to understand. I think that, next
to
the way a closed loop system works, understanding perception is the
toughest
part of PCT. Now that I think of it, it might be worth it to try writing
a
tutorial on perception aimed at the lay person. Perception is central to
the
PCT approach to behavior and I think a lot of people have a l trouble
getting
their arms around the PCT view of perception. I think most people look at
perception as being a "point of view" on things. Perception, to the
layman,
means "subjective interpretation" or "the way things look to me". That's
close
but perception is a bit more complicated than that. I'll try to write a
simple
tutorial on perception from the PCT perspective. I think such a tutorial
would
be very useful.
Graduate school?, The greatest philosophers in the world have been trying
for 350 years to answer that question. I too believe the hierarchy is _part_
of the answer. The other part, awareness, is bit of a distance away. I
believe a"tutorial" would be a waste of time as long as you give yes and no
answers to questions. It might prove to be prudent to differentiate between
Perceptual signals and perceptions, with each having a specific meaning in
the model.

Well, yes. That would have been my guess. I'm sure I'm wrong, though. How
many,
really?

These questions are way too difficult for me. Why toy with me? Please just
tell
me how the fielder knows its a ball.
Review your graduate school books on perception.
I'm also real interested in your response to Bruce Gregory's post;
[From Bruce Gregory (2003.0525.1736)]
I may well be mistaken, but this is how I see it. PCT is a model
(defined by the a set of equations) that describes purposeful behavior.
As far as I know, PCT contains no comparable set of equations that
describes:
1. Memory
2. Emotion
3. Imagination
4. Cognition
There are stories about how each of these might someday be incorporated
into a more encompassing model based on PCT. These stories are more or
less persuasive. They are not, however, models and as such lack
predictive power or the capacity to be rigorously tested.
Is my understanding flawed?
Well? Is his understanding flawed? I would like to know.
