  If you ever discover any detectable property that produces redness, that

have been falsified and you must then simply alter your sets of necessary
and sufficient detectable properties, to include the new property.

### So you say the quality of redness is possessed by any physical object
(whether glutamate or not glutamate) that produces the perception of
redness.

How is that not a circular argument?

### Almost all neurons are binding neurons. The neurons that construct the
perception of redness are in the V4 area, and respond the same both to
physiological (reflectance) and certain non-physiological (monochromator)
stimuli. Redness does not exist as a property below the V4 area. Most
cortical neurons have glutamatergic synapses but only V4 neurons use
glutamatergic transmission to construct the quale of redness.

Glutamate is a transparent, easily crystallizable substance, and produces a
pleasant taste when applied to umami receptors in the mouth. It has no
"redness" quality.
