I prefer to think of the distinction between reality and our models of it not in terms of single-level versus multi-level but rather in terms of the thing itself versus descriptions of the thing: conceptual systems have levels, reality does not.
Thinking in terms of levels is applicable to conceptual systems, but not applicable to reality — applicable to conceptual systems about reality, but not to reality itself.
The notion of level is just a mental construct that is helpful in describing how we think and how we represent. It is a function of how we carve up reality conceptually, but reality itself doesn’t contain bones and joints that are waiting to be carved — not even just one fundamental joint that we have no choice about how to carve.
