I appreciate the response, and I read your article. The only thing I find noteworthy is that I cannot help but notice a paradox within this dimensionality approach to the universalist ontology.
I think that to see a premise of compartmentalisation and to say "There is a higher level" is in fact to fight compartmentalisation with compartmentalisation.
Surely the correct approach is to remove all levels, and understand that the universe is only that: A universe. A singular spectrum wherein all the data, investigation and analysis exist beyond any levels or even abstractions.
An abstract analysis of the universe would be a theory of anything, I believe a theory of everything would be to somehow conclusively remove all abstractions and finding out precisely what remains.
