What about it seems like mental gymnastics? Surely not the length or detail of the article, which is pretty true of every philosophical idea.I skimmed through it and it seems like some Olympic level mental gymnastics with pinch of indirect dualism. Perhaps you could point me in the right direction by highlighting what you think is important from your own source?
And I don't see anything dualistic about it. If you want a simpler version of substance monism in theory of mind, there's always the Qualiasoup videos.
