Re: What is closure?

JohnK,
"Closed to efficient causation" has nothing to do with "closed systems" in
thermodynamics. The word "closed" has an entirely different meaning in the
two usages - the former has to do with loops of entailment, the latter with
thermodynamic isolation. The two concepts are radically distinct and bear no
relationship to each other just because they share the word "closed". To
speak of "closure" in some kind of generic sense (whatever you might mean by
that) only adds to the confusion.
I agree with you that not *everything* about an organism in terms of
efficient cause is entailed within the system. Rosen's assertion about
"closed to efficient causation" does not make that claim; his claim has to
do only with the manner of the relational organization of entailments of
functional components. See my post from this morning.
Regards,
Tim
