It seems to me you're still directly on topic.  Nick's emphasis on hierarchy 
leads directly to (forgive me, here) the *flatness* or flattenability of 
dynamical systems equations versus whatever units multi-level selection might 
operate over.

It's probably just another fit of apophenia.  But I just finished my 
incompetent reading of McShea and Brandon's "Biology's First Law", wherein they 
criticize the Hardy-Weinberg "law" (at least as a universal biological law) 
and, later in the book, assert that their ZFEL is strictly hierarchically 
applicable.  They go on to reference Bouchard 2008 
(http://www.fredericbouchard.org/textes/BOUCHARDcausal_persistence_fitnessPHILSCI08.pdf)
 and say:

McShea and Brandon, § A Generalized ZFEL for Physical Systems:

This hearkens back to Nick's attempt to paraphrase Rosen with:

Rosen specifically targets operational closure and material openness.  But 
McShea and Brandon seem to argue obliquely against that earlier in the book:

McShea & Brandon § Forces and Null Expectations:

Anyway, there are 2 questions that this apophenic fit lead me to: 1) Are the 
"higher order" constructs (including your interfering distributions, M&B's 
"lineages", units of selection, etc.) reducible to "lower order" constructs -- 
i.e. what I infer as John's implicit assertion that a sequential machine should 
be able to reproduce *any* chronicle? And 2) Are material and organization 
*actually* separable or do they always remain at least a tiny bit dependent?

Regardless of any of that, though, I'd also appreciate any and all opinions 
about M&B's ZFEL.  In my googling, I failed to find criticisms of it.  My 
skeptical homunculus refuses to remove the handcuffs from my gullible 
homunculus *until* I find a scathing criticism.
