Do you mean by "life is a human invention" that the distinction between living
and non living is a useless one? If it has value, then what is it you
are trying to accomplish by redefining it? If it does not, what is the point?
We seem to have a widespread consensus that the distinction is of importance,
or Shrodinger and so many others would not have tried to deal with it.
Trying to extend the concept to atoms, etc. seem at best counterproductive.

I don't think so, at least from the content of this message. Let's see why.
First of all, as I recall the majority of things which once lived are now
extinct ( an interesting word "extinct" which again implicitly says
that the condition of living species is less than stable in the long term.)
which seems to pose a problem for the notion of stability. The why of life
certainly seems to be directly related to a stability condition, not that
of particular life-forms however. Kay and Schneider posit that the purpose
of life is to stabilize the conditions on the planet which make life possible.

Yes! I don't get your point. Redefining words to include more and
more is always dangerous since so often the result is thgat the words
loose their meaning. As I recall, you seem to like to give new
definitions to old words and I find it very confusing. Here is a place where
the stuff we've been talking about might help. First thought, biology makes
a clear distinction between the notion of parasite and non-parasite ( I grant
that the distinction gets tough in some cases). Sociology borrowed the
concept, and with it the distinction. Now, if we were to agree that organisms
must be closed under efficient causation, the distinction has real meaning.
Dependencies auch as humans needing essential amino acids would not
constitute parasitism. However an organism which needs genetic
apparatus from something else would be a clear example of a non-
organism. What seems to be the real interest in this is the notions
of symbiosis and other concepts which come from a less reductionist
view of the issue. Situations where the whole becomes more than the
sum of the parts and different from the parts are the crux. Mere dependecy
seems a tautology.

Intweresting! I always associate "Gestalt" with holistic thinking. Am

Does this mean that things which go extinct are not alive? Does evolution
negate stability? I find this whole line of thought very confusing. Stability
of what? The ecosphere perhaps? Need we read these references befor
we can understand you? If so haow to get them?

At each level, the environment and all the interactions are so important.
The project to create an artificial biosphere was incomplete due to a
lack of earthworms. Does this consitute vertical or horizontal parasitism?

Yes, but the interdepencies are at all levels and between all levels.
What do we gain from the vertical/horizontal reduction? What is wrong
with the ones ecologists spent years putting together?

What about foodwebs, communities, etc. Is there something wrong with these
distinctions and interrelationships? What is it you wish to accomplish?
What is wrong with the exisiting body of work in this area? Is the distinction
between those entities which are closed to efficient cause flawed? If so
where? If not why do you reject it? Sorry, but I wonder if this is a
better wheel at all?
