I know Doug, and I assure you you're right. I was at Indiana University
for awhile.

[1] Agreed -- "Mu" is more difficult that the "size of red".
[2] Well, "density" here would be a "quantitative" magnitude, and I can't
ask how "extended" 129 is; of course this is nonsense, but surely you
are referring here to mathematical rather than metrical space. When I
experience, say, a pure red painting 6 X 4 feet, my "patch" of red is
much larger as a percept than my occipital lobe, and we know this
redness is a sensation (i.e. experience), not a property of an object.
My point here is that the concept of metrical "space" is merely a con-
ventional artifact of objective measurement; it cannot possibly account
for the perceived qualities of purely experiential components.
I must remind you that my sensation called "redness" cannot be an
observable object regardless of the refinement of our instruments.
It may be possible to "measure" red, but only analogically by means
of some other continuous variable, just as we measure the density
of electron drift by means of its associated magnetic field and the
deflection of an ammeter pointer induced by this field. In this sense
we might "detect" when a subject was experiencing red, but this has
nothing at all to do with the experience itself.

Once again, a comparator does not recognize identity; it merely generates
a pulse (or some other output depending on the gate configuration) when
A - B = 0.
Your post contains details that I want to think about some more; it
was certainly most stimulating. Thank you.
