Re: Could you give me your analysis of this?

Rehashing the topic of "closed to efficient
causation" ........
The entire relevant paragraph from
Life Itself:
"The answer we propose is now this: a
material system is an organism if, and only if, it is closed to efficient
causation. That is, if f is any component of such a system, the
question "why f?" has an answer within the system, which corresponds
to the category of efficient cause of f. In terms of the graphs we
have been using, every component must (1) initiate a red arrow, since it is a
component, and (2) terminate a green arrow. We claim that everything else
about organisms, everything studied in biology by biologists, and much else
besides, arises from and devolves upon this property." [p. 244, ital
orig.]
Rosen clearly spells out what "closed to
efficient causation" means in the second sentence:
"That is, if f is any component of
such a system, the question "why f?" has an answer within the system,
which corresponds to the category of efficient cause of
f."
"Closed to efficient causation",
then, specifies that any component (i.e., a "particle of function" or
"functional unit" (see sec. 5F)) will have
an entailment of efficient cause
from within the system. What this sentence does appear to
specify is a minimum criteria for the organization of the entailment structures
of functional components in an organism. By the use of the 'an', he certainly
does not seem to assert that these components cannot also have
additional entailments of efficient cause (which may arise from outside
the system).
"Closed", then, does not mean "closed
off". Instead, it means that one can chase through a relational
organizational diagram of the components in an organism and one will
be able to trace a closed loop of efficient cause entailments
through the diagram.
Now, either there is such a closed loop one can
trace or there isn't. I do not think it is meaningful to say that one
could trace a "relatively closed" loop. If
there isn't such a loop, then Rosen's thesis about organisms is in great
jeopardy. If there is, then this affirms his thesis.
