*Quality: a distinctive attribute or characteristic possessed

Imagine there are 2 things, for example 2 strawberries with a redness
quality. Can we say one strawberry is more red than the other? Yes, we can.
We could for example measure using a spectrometer the spectrum of the light
coming from the strawberry when exposed to natural light and sum the
intensity of the peaks in a given region we agree that correspond to red
(that is going to be arbitrary anyway). One strawberry would be more red
than the other for sure. We can organize a bunch of strawberries in that
way according to their redness "quality". If one is worried about machine
vs human perception we can ask people to do the ordering of the
strawberries in terms of their redness (and probably found out that is not
identical but very similar to the one done by the machine).
Anyway, the purpose of the above exercise is to make a claim that actually
what we call a quality is in fact a quantity, that can be measured. The
word quality at most tell us what we are trying to measure (a certain range
of light frequencies intensity). Notice that there is nothing intrinsic in
this quality and it is associated to the characteristics of the object.
Now if you are interested in the subjective experience of red then you can
do exactly the same experiment measuring some kind of correlate that
corresponds to the perception of red that how it has been pointed out is
understood pretty well from a neuroscience point of view. The complication
here would be that individuals respond similarly to stimuli but with
noticeable individual differences and by doing this experiment we would
also understand that variation in individual response given the same
stimuli. This is all there is to understand from a scientific point of
view about red.
If one insists that there is an "explanation gap" it is because they don't
understand how science works and what science is all about.
It is a map of the universe, not the universe.
A map is not useful when it represents 1-1 to the territory.
What Brent is complaining about is that the map is not the territory (we
cannot EVOKE the experience by using science). Of course is not and it
should not be, because if it was doing that it would be useful as a model
of the world.
Models are not necessarily true, but they need to be useful to be good
models.
