Re: Entailment in the Ambience: Causality



Tim,

This was a brilliant post, in my opinion. You nailed it.

I'd like to elaborate on this statement:

systems.


Tim has hit on one of the main reasons Aristotelian analysis suited my
father so well in analyzing biological systems: The generality. The aspect
of complex organization, particularly in biological systems, which makes
such systems so inappropriate for reductionist analysis is that the "parts"
don't just serve one function, and there's no way to know whether there's
even a finite set of functions-- and they do it all simultaneously. As such,
the different categories of cause would also continuously apply to the same
"parts" in different ways, ways which are also constantly shifting. You have
"parts" (be they cells, organs, subsystems, whatever) relating to one
another and those relationships are also relating to one another, creating
other relationships-- which all have to be considered "components" of the
system organization... and the whole thing is constantly interacting in a
balanced way that maintains system stability in a fluctuating environment.

This is one of the things that drives evolution. I remember a discussion
with my father about his explanation for the development of lungs: He said
it likely began as a "swim bladder". In many aquatic creatures, this organ
serves to help with bouyancy and balance. Obviously, it's got its own blood
supply, so there would be an exchange of oxygen occurring. Those with more
blood supply would have more oxygenation taking place. This likely preserved
life in an organism that otherwise would have died in low water conditions,
so the trait got passed on. Ultimately, the swim bladder is now a different
organ altogether --a lung-- with a different set of functions-- and would be
useless to us as a swim bladder. Some may describe that process as a "happy
accident" but my father viewed it as causally based. So, evolution, in his
view, was not just a history of happy accidents. The more we learn about
complex organization, the more we will be able to understand the kinds of
entailment involved.
