In the text above, you use what some linguists call "is of identify".
Does all your words "red" above really point at the same concept <red>?

In the standard discussion among humans on this matter, one can easily
remove the problem using the General Semantics method ``indexing'':

\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/
There exists a defined wavelength of light called red[1].
There exists a defined sensory cone in the eye that exists called a red[2]-
receptor.
There exists a defined chemical loss in the retina associated with red[3].
There exists a defined signal along the optic nerve that denotes red[4].
There exists a defined perception in the brain called red[5].
There exists a defined memory encoding that stores red[6].
\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/

Do you mean to state that all red[k] (k=1,...,6) refer to the same phenomenon?

You know, there exists a complication here with the fuzziness of the natural
languages: The ``eye'' you refer to above really does not exist.

There exists a number of different eyes, and eye["Person 1"] and
eye["Person 2"] do not necessarily have the same receptiveness for light,
and thus can (and will) give a somewhat different reception for the same
input light.

Person 1 will state that the eye sensory input matches ``red'' while Person 2
will vehemently state that it does not. They use different definitions of the
word ``red''.

One could of course define the meaning ``red'' with a physical characteristic:
``The word "red" refers to the colour of light with a wavelength between
460 and 780 nm.''. [This probably won't match what _your eyes report, BTW. !-]

Then one could either call humans who do not follow this rule ``colour blind''
(optically challenged?) or ``mistaken'' (semantically challenged?).
