Azamat,    (02)

Let me challenge, not as a criticism--more as a candidate segue into a
different conversation, something you said:    (03)

I ask:    (05)

Where in that world view do you account for, or represent, emergence?    (06)

AA: Self-organization and emergence are parts of complex systems, the 
systemic effects of nonlinear causality, when small changes can have large 
effects whereas large changes can result in small effects, and the whole is 
more than the parts, when the beating of a butterfly's wings unleashes the 
hurricane on the other part of the globe.
All self-organizing systems are complex system, but not vice versa.
The matter's been ventilated:
http://ontolog.cim3.net/forum/ontolog-forum/2011-08/msg00103.html    (07)

Where does that world view account for life itself, other than, say,
as an emergent property of mechanisms associated with zillions of
chemical reactions?    (08)

AA: It's about self-organizing and self-producing (autopoietic) living 
things interacting with the environment, about organic networks of 
feedbacks, negative and positive.
Although, the mechanisms of virtual/artifical life look simpler to reverse 
engineer.General living systems ontology for how all living systems work is 
looking for its champions.    (09)

My own thought is that the very term "mechanism" doesn't belong in
conversations about "systems" which cannot be defined as machines.    (010)

AA: it's too narrow. In a broad sense, "mechanism" is to cover "organism", 
"virtualism", all kind of systems, natural and artificial, living and 
nonliving, social and technological, etc.    (011)

That, of course, is another subject, one well worth its own
conversation.    (012)

Perhaps I am asking a different question: what are the limits of
ontology engineering as we presently understand and practice it?    (013)

AA: It closely depends on how one sees ontology, its scope and scale, and 
application fields: if it's about pieces of reality (entities and 
relations), conceptual representations (knowledge systems), or languages 
(terminology, vocabulary). Three-in-one is a sure way to achieve.    (014)
