Ken -
 
Reductionism has its place in the analytical phase at equilibrium.  Analysis is normally a study of integrable, often linear systems, but it can be accomplished on non-linear, feed-forward systems as well.
Well said... 
The synthesis phase puts information re: complex behavior and emergence back into the integrated mix and may be "analyzed" in non-linear, recurrent networks.
It is the synthesis/analysis duality that always (often) gets lost in arguments about Reductionism.  There are very many useful things (e.g. linear and near-equilibrium systems) to be studied analytically, but there are many *more* interesting and often useful things (non linear, far-from-equilibrium, complex systems with emergent behaviour) which also beg for synthesis.
This is actually a probabilistic inversion of analysis as described in Inverse Theory.
I'll have to look this up.
 
Bayesian refinement cycles (forward <-> inverse) are applied to new information as one progresses through the DANSR cycle. This refines the effect of new information on prior information - which I hope folks see is not simply additive - and which may be entirely disruptive (see evolution of science itself) .
Do find this applies as well in non-probabalistic models?
 
The fact this seems to work for complex systems is philosophically uninteresting, and may ignored - so the discussion can continue.
"seems to work" sends up red flags, as does "philosophically uninteresting".  I could use some refinement on what you mean here.  
Final point: Descartes ultimately rejected the concept of zero because of historical religious orthodoxy - so he personally never applied it to the continuum extension of negative numbers. All his original Cartesian coordinates started with 1 on a finite bottom, left-hand boundary - according to Zero, The Biography of a Dangerous Idea, by Charles Seife.
And didn't Shakespeare dramatize this in his famous work "Much Ado about Nothing"?  (bad literary pun, sorry).
