Bill Powers (990811.2011 MDT)--
If your reference level defines a nonzero amount of "stable and continuing"
as what you prefer, then what's good (for you) is what's stable and continues.
Otherwise it isn't.
Tautology, so true. But are you claiming that reorganization
doesn't universally lead to either a relatively stable set of
references or else the dissolution of the organism? It's not
just what I prefer, it's what reorganization -- and before that,
evolution -- produces.
Bill Powers (990811.2011 MDT)--
What you're trying to prove here is that there is an objective
basis for deciding this issue.
I don't think so. I'm claiming that all life is subjective, including
people who want to be objective. Of course, by arguing "logically"
I am making an "objective" claim -- stating that all life is subjective.
However, I don't think this causes any more problems than the
fact that the set of all sets can't be defined like all the other
sets. It's another instance of Godel's incompleteness theorem:
you can't have a closed language that's totally defined by elements
within the language.
You have a reference for being objective. I do too. However, I
believe that the individualist stance -- "I prefer what I prefer,
and that's the end of the argument" -- denies that we are all a
part of life, and that life itself has values, references, that are
common among us all. Therefore, the objectivity I would aspire to
is in the context of this more inclusive set of values than those
in individual nervous systems, however speculative that may be
at this point.
Bill Powers (990811.2011 MDT)--
You can't use what you're trying to prove as a premise in the argument.
Well, you can, but not if you want to convince me, or a logician, of anything.
I don't want to try to convince logicians -- it's too difficult, unless
they already subscribe to a pragmaticist, contextualist perspective
(instead of accepting only a truth-value formal logic as the end of the story).
Truth is a subset of what endures, not the other way around, in my view.
Bill Powers (990811.2011 MDT)--
Actually, I think that what's stable and continues -- SR theory -- sucks.
You've already shown how it is unstable and won't continue. It's your
own reorganization system that's to blame. It won't let you accept
SR theory, because of the conflicts with PCT.
Chris Cherpas (990811.1130 PT)--
Following the chain to the end leads to an absurd conclusion: having a
reference for not surviving. How can that be stable?
Bill Powers (990811.2011 MDT)--
I'd say it's quite stable, although I'm not sure that "stable" is what I
prefer. Suicide has been a major cause of death throughout recorded
history. Suicide is one logical solution to a certain class of problems.
If it were "stable," and widespread throughout living systems, that
situation wouldn't last long, and it couldn't be considered stable
anymore. Suicide is not a major cause of death -- it's an exceptional
cause. It is a logical solution -- a neural solution -- not as
pervasive as the outcomes of chemical control systems which are not
suicidal (unless viewed anthropomorphically).
Bill Powers (990811.2011 MDT)--
But one perfectly permissible value of a reference signal is zero.
You assume that to "have a value" is equivalent to having a _non-zero_
value, or a value high on a scale.
I don't understand why you say that. I thought my criterion of "stablity"
was vague enough to include any interpretations that are based on the
absence of something as well.
Chris Cherpas (990811.1130 PT)--
To be coherent, the science is only relatively objective,
but is ultimately subjective -- value-based. Science refines our
ability to organize towards continuing, towards stability. To be
"coherent" is another way of saying that there is a minimum of internal
conflict and instability.
Bill Powers (990811.2011 MDT)--
Well, I guess this shows that you like stability and coherence. But you're
going to have to look a long time to find an objective justification for
that preference. Why not just admit that you prefer it? You have the right.
I think PCT shows that we're stuck with that, because of the way
reorganization (and evolution) works, not that I personally prefer
stability and coherence.
Bill Powers (990811.2011 MDT)--
Is there ONLY ONE such set of preferences? Of course not: life is
a succession of bifurcating possibilities, and many branches would
be just as viable as many others.
...as many others, but not all others. That's the point. It's
bounded, constrained. Once it bifurcates into an unrecoverable,
entropic state, "it" isn't life anymore.
Chris Cherpas (990811.1130 PT)--
This is not teleological or to say that genes have
a purpose to survive. It merely says that what we call valuable is
a generalization of perceiving what continues and adapts, rather than what
falls apart.
Bill Powers (990811.2011 MDT)--
This assumes that we prefer that which continues and adapts rather than
what falls apart. Now you have to justify that, and in doing so you will
express still other reference conditions you will then have to justify, and
so on ad infinitum.
Not really. Life itself does not require justification. It does
not require a purpose. It _is_ purpose. Beyond that it can be said
to have stability, continuity, as does non-living matter. Purpose
is one way that stability occurs.
Bill Powers (990811.2011 MDT)--
You will never arrive at a self-evidently correct
statement of what is good.
Life itself defines the good (and the bad). Without life, the
question of the good does not arise. Once life is evident,
what is good is (within that context) self-evident.
Bill Powers (990811.2011 MDT)--
You're treating "value" as if it were always positive and nonzero.
Again, I don't think I'm being that specific, so I don't think
I am treating it as positive and nonzero. I'm probably missing
something here.
Anyway, I sense that I'm more "right" and you're more "wrong"
on this, but I can't think of any more arguments. Maybe you can
persuade me that PCT cannot tell us what is "good" for life, not just
individuals, but I sense that we may be at an impasse that won't
be resolved in the near future.
Best regards,
