Re: Operational Closure

Tim and Judith:
"A" cause is chosen from and for a limited model. It is the natural system's
total change that results in an 'event' and I wouldn't even call the
triggering (good word!) as a 'beginning', rather as the observed immediate
'affectings'.
It is also a consequence of the process in the totality. And I would cut out
the limited view for a M-V 'system' ("subset").
Organizations consist of organizations consist of organizations - our view.\
I am seeking those general distinctions that are applicable at any level.
I don't care if Org.#1 consists of people, of cells, of atoms, of stars?
all these are well defined (limited) models and subject to general
principles.

(Happy to see the list alive again).
