I thought this video would end this discussion about redness quality stuff
forever but it seems to have done almost zero impact. Any scientific mind
would see this video and realize that "redness" is an illusion as I said
before. In which sense is an illusion? It is not "something" like you say
it is, it is not made of a single or simple substance in the brain or a
simple process it is a complex series of events in the brain, it is a
delicate process that can be hijacked by illusions as the one described in
the video. This indicates the information that we interpret as redness goes
through many stages, it requires different parts of the brain and it is not
as solid as Brent thinks. It is not something one can "poke" as your
elementary school students proposed or pinpoint. It can be still studied
and understood scientifically but the functionalist intuition on this
phenomenon is supported by the evidence shown in the video.
The video is basically fatal to your naive understanding of redness.
