RICK:
(3) I can also write the filter into the program that coverts the light into
a digital image. If I do this the monitor will change from blue and green
to gray because while the light did enter the camera and get passed on to
the computer, it never made it to the monitor.
Now... The camera is an eye, the computer a brain, the light-digital
conversion program is a cultural definition of what is real and unreal and
the monitor is a field of vision.
Example 3 is a Natchez; the light reaches his eye and is passed along into
the brain, but it's filtered out by cultural definitions of what is real and
unreal before reaching the field of view (ie. before it shows up on the
monitor... 'UNVISUALIZED').

ERIN:
Okay I don't get this filter that defines what is real and unreal. To me this
filter is our memories/language, etc. The only way the green and blue would
be converted to two shades of gray is if they were colorblind.
There are three color cones in the eye--red,green, and blue. For the Natchez
have a green-blue blindness they would need some physiological defect.
If you can teach the green -blue distinction, then guess what there was no
defect. Do you think the green-blue cones miraculously divided into two?
Glenn I find it amusing that you have a hard time swallowing Pirsig but can
ponder if the Natchez tribe is colorblind or not. If you think culture can
cause or cure colorblindness then who is the extreme relativist you or Pirsig?
