hmmmmmm. 'perilous' indeed. "effectiveness" can be a
relation appreciated only from the 'outside' of a system,
yet it can also be something that occurs from innate
events, irrespective of any external evaluator.
At this moment in my thinking, I don't see as
how I could side with either view exclusively.

My phrasing of it looked like this: "if any anomaly arises
in a paradigm, then the paradigm, no matter how good
'except for that anomaly' has to be scrapped and replaced
with one that accounts for and embraces the phenomenon
so that it is no longer an anomaly."

FANTASTIC!. I have been taking-on Godel since day-one of my writings,
challenging erroneous premises and pre-set limits which invalidate
any attempted generalization of his incompleteness theorems.
There have been several "limits to knowledge" conferences, Sci-Am
articles and books, and general extrapolations of Godel's
theorems, which became the rage of the scientific community.
All balderdash, IMO. To know that Rosen also saw that
emperor godel wears no clothes is gratifying.

In this, I take another path than he did. I -do- see a "decision
procedure, that finds us the organisms in a presumptively larger
universe of inorganic systems."

I never imputed any. I'm asking about it in consideration
of 'actions enactable' within a domain that is larger than,
equal to, or smaller than, the whole performance domain,
however large they may be individually or relationally.

Again, I take a different tack. I deduce that a small
number of behavior rules -can- generate performances
as we know them, and, can generate 'life' from primordial
aspects that wouldn't qualify as 'life' in and of themselves
alone.
