The Mathematician Pappus records Archimedes [287-212 BCE]: ‘Give me a place to stand and [with a lever] I shall move the Earth’.
You don’t need to move the Earth. But you do need to step back to Nothing to see what’s going on with Everything.
In looking for ‘Everything’, you must remember to include the Looking-Subject. ‘Everything’ is radically inclusive.
In looking for ‘Nothing’, you must remember to exclude any sensory, cognitive or affective representation of it as Object. ‘Nothing’ is radically exclusive.
But what happens if you forget the Looking-Subject? Or stop-short of Nothing at ‘Something’? A new and sophisticated word for this forgetting is ‘Self-Reference’. And to get stuck in it is to get snarled in the Self-Loop.
