The brain has a part of itself where thought is located. If they snip that part there no longer is thought. In One flew Over The Cuckoo’s Nest, Jack Nicholsen just lies in bed while the chief grasps what they did to him. If you remove that brain part then you are no longer Bob or John or Broomhilda. So the thought part declares itself “I” as in I am Stan and I have a brain….but that is not so. The brain was never separate from the part that declared itself separate. A film is projected on screen containing characters that declare themselves real but they are merely projections. You can whistle the melody of the song and at the same time no note is real. So if one becomes fixated on being more like this or more like that, for who is that for considering you don’t exist in the first place?
