Thanks for explaining where you’re coming from.
Yet I experience that computation as the qualia of “blueness.” How can that be? How can any computation of any kind create, or lead to qualia of any kind? You can say that it is just a story my brain is telling me that “I am seeing blue.” I must not understand what is being claimed, because I agree with it and yet it doesn’t remove the problem at all. Why does that story have any phenomenology to it? I can make no sense of the claim that it is an illusion.
As I understand it, the idea would be that, as weird as it may sound, there isn’t any phenomenology to it. Rather: according to the story that your brain is telling, there is some phenomenology to it. But there isn’t. That is, your brain’s story doesn’t create, lead to, or correlate with phenomenal blueness; rather, phenomenal blueness is something that the story describes, but which doesn’t exist, in the same way that a story can describe unicorns without bringing them to life.
