Thank you, Eric for your considerate reply, however more comprehensive
(branching into math) than I can absorbe all of it.
Please see my remarks interjected as lines between ********

I also think in second thought that my statement is NOT correct. I mixed the
(misused name) complexity, indeed a set of all descriptions with the model
we form within a topic (a defined subset).
Once you mention a 'pattern', it is a model. A cut-off view within the
topical interest of the observer. In the 'emergence' as I formulated it, the
effect of the "total" is invoked, influences from broader sets than the
model itself.

I find mathematical examples off (my) base, since math is 'describing' the
model and so it is the map of the territory - where the territory itself is
also only a model of our viewed (selected) part in question.

You said it in the last three words. I try to generalize (which is, of
course,  beyond my capabilites, but so be it: I don't cut my inqueries to
the conventional old reductionistic knowledge in searching for new views).
Your "completely" described pattern is still an "incomplete" model.
[let me skip your example #1, the "A" to it, shows the "model" indeed]

I don't know what is "life", especially "human life"? There is a 'pattern'
in processes of changes in parts of the complexity which - at a certain
level - may be called 'life', not essentially different from other types of
change.
How good old reductionist science boxed in the models formulated under this
name are good for the developmental sequence in the inquiry, but do not
contribute much to my search of fundamental generalization. The
organizations are interconnected and interinfluenced, which makes the
difference between a machine and a natural system (words borrowed from
Robert Rosen's vocabulary).
Cellular processes IMO are definitly model based cut-offs.

I subscribe to every word you wrote, within the description of the
reductionist modeling of patterns, theories,  functions, chosen to a
"purpose" or "usefulness". I think we use the word "emerge" in different
meanings: you condone it for a result of a known process with different
qualia than the participating components, while I restricted it to the "awe"
of an unknown appearance of a surprizing (new?) feature.
Your (?) addition in the Subject ("or is that "re-emergence") shows the
relevance of the difference in meaning. "My" version cuts out definitely a
"re-emergence" meaning.
I think the big fashionable hoopla about 'emergence' during the past decade
was impressing (annoying? trapping?) me.
I don't argue for the correctness of my definition. It is 'one' definition.

How about the "unrealizable" patterns, like natural systems, with unlimited
variables and qualia beyond our inventory? covering unlimited scales?
Are they also computable? (that would embroaden my feeble imagination of
math).
