It is my impression that certain people think that illusionists deny that there is any 🟩 even in the map, and I have never heard any illusionist make that argument (maybe I just haven’t been paying enough attention though). The conversation seems to be getting stuck somewhere at the level of misunderstandings concerning labels and referents. The key insight that I am trying to communicate here is that when we say that A is B, we generally do not mean that A is strictly identical to B—which it clearly isn’t. This applies even when we say things like 2+2 = 4. Obviously, “2+2” and “4″ are not even close to being identical. Everyone understands this, and everyone understands that when we say that 2+2 = 4, we use two different sets of symbols to refer to one single mathematical object.
Claiming that greenness is activity in the visual cortex does not amount to denying that there is 🟩.
But again, perhaps I just misunderstand illusionism (although not even Keith Frankish himself would deny that there is 🟩, see the video linked in the post). Are there any illusionists around here who are claiming that 🟩 is not?
As a side note, perhaps I will stop using the verb “to exist” altogether, and instead start using “to be”.

This seems to mix up labels and referents. 2+2 is strictly identical to 4. The statement “2+2=4” is not the same as the statement “‘2+2’=‘4’”

The referent of the label 2+2 is strictly identical to the referent of the label 4, but the labels 2+2 and 4 themselves are obviously not identical.
