You appear to be assuming that the credibility of the posit (of a UR)
depends upon acquiring knowledge of the properties of that which is
posited. It doesn't. In fact, since the posit makes no statements about
any properties of the entity posited, any statements predicating any
properties to it will have no bearing whatsoever on the posit's
credibility. The posit becomes more credible if *what it asserts*
becomes more probable. The posit merely asserts, "Something exists
external to the ER, which is the cause of the ER." Any statements
imputing any properties to it will be irrelevant to the plausibility of
that posit.

The models of the CR *presume* the UR. Every CR model which postulates
an external --- atoms, quarks, waves and fields, etc. --- entails the
UR, e.g., "Atoms exist external to the ER" entails, "something exists
external to the ER." This is a strict logical entailment. Thus if some
empirical evidence renders "Atoms exist external to the ER" more
probable or plausible, then that same evidence renders the UR more
probable or plausible, to precisely the same degree.

All possible CRs are instantiations of the UR, as long as they postulate
externals which have a causative role in the ER, regardless of what else
they may also posit, and regardless of the causative mechanisms posited.
They are all possible URs. We adopt as a "stand-in" for the UR that CR
which, among all the CRs known to us, best accounts for the ER phenomena
we observe (because that is the role posited for the UR).

Nope. The "grounding" of the UR (and that is not the most apt term) has
nothing to do with being alone in the world, or an inchoate belief that
"there must be something more." The UR is posited because a being which
has come to differentiate between itself and the "other" which it also
perceives, and is inquisitive, can find no cause for either itself or
the "other" among its own percepts (i.e., within the ER). So it must
choose between positing the existence of something external to itself
and the ER (I'd like to just collapse that dichotomy into the ER, if it
will not cause confusion), or accepting that the ER has no cause. The
latter choice would be for solipsism (nothing exists except the ER).

(It could also here propose that something exists beyond the ER, but has
no causal role in the ER. I'd suggest it would not find that possibility
very interesting, since there is no apparent way to pursue it
productively, and thus it could not assuage its curiosity regarding its
own existence).

Solipsism asserts, "Nothing exists beyond the ER." The contradictory of
that negative universal is, "Something exists beyond the ER." The latter
proposition is the *minimum alternative* to solipsism. We *prefer* the
existential to the universal, because the existential ("Something exists
beyond the ER") opens the possibility of finding a cause for the ER. So
we posit the UR: "Something exists beyond the ER which is its cause."

We now have a *minimum metaphysic* which enables us to explore possible
causal mechanisms for our own existence and the other phenomena we
encounter within the ER.

Oh, but it does. Atoms *necessarily* exist external to the ER, if they
exist at all, because they are not experienced, i.e., not encountered
within the ER. *We are postulating the existence of something we do not
perceive within the ER*. Hence it is necessarily external to the ER (if
it exists at all).

Again, don't confuse the posit itself (that atoms exist), or the "idea"
or concept of atoms, with the atom --- that which is posited to exist.
The posit, the "idea" and the concept are all elements within the ER.
But the atom is not. "The atom is an idea postulated in the CR" is
*false*. The atom is that which the idea is *of*. Atoms cause chemical
reactions, not the "idea" or concept of atoms. Similarly, what is
posited is the atom, an entity existing outside the ER, not the "idea of
an atom."

I'm suspecting that this identification of an idea with its object is a
major culprit in our seeming inability to find common ground here. I'm
wondering if you appreciate the consequences of that identification.
Consider the posit:

P1.: Something exists external to the ER, the atom, which has such-and-
such properties and which causes so-and-so phenomena within the ER.

You wish to claim: "P1 is nothing but a posit within the ER."

The consequence of that stance, if you take it consistently for all Ps,
and were it to imply what you think it does, is that nothing exists
external to the ER --- which returns you to solipsism.

But it doesn't imply what you think it does, namely, that because P1 is
"nothing but a posit within the ER," that what it posits is *also*
"nothing but a posit within the ER." That faulty implication explicitly
contradicts what the posit explicitly states. By drawing it you are
simply denying what the posit states, without grounds, and in the
process retreating to solipsism.

Entities hypothesized to exist external to the ER *do* exist external to
the ER, by hypothesis (if they exist at all). They are not hypothesized
to "correspond" to anything else presumed to exist external to the ER.
But you're right that "Their existence as ideas residing in the CR is
quite a different issue to the proposition that 'they are external to
the ER'". And it is the latter, not the former, which is hypothesized.
That atoms exist as "ideas within the ER" is an experiential fact about
the ER; that is not an hypothesis. The hypothesis is that atoms exist
external to the ER. That is the hypothesis we wish to test, by
investigating the consequences within the ER which the hypothesis
predicts.

There is no "further proposition." The entities are external to the ER
*as hypothesized*, and necessarily so, because they are not experienced
within the ER. Only the ideas of them are experienced, and thus within
the ER. But ideas do not have atomic weights, charge, mass, etc.

You are right, of course, that hypothesized entities may not exist. That
is why we test the hypothesis. Successful tests render the existence of
the hypothesized entity more probable; unsuccessful tests render it less
probable.

The posit, "Something exists external to the ER, which is its cause," is
indeed metaphysical speculation. The posit, "Certain (specified)
combinations of matter, external to the ER, yield ERs," is not a
metaphysical speculation, but a theoretical one. It is testable, in the
same way that "Certain (specified) combinations of matter, external to
the ER, yield hurricanes" is testable. Both theories presume the
metaphysical UR.

Well, then I don't know what you require to gain confidence. Normally,
if an hypothesis predicts certain consequences, and those consequences
are observed, it increases confidence in the hypothesis. That's what
"confidence levels" in hypothesis testing attempt to measure.

Speculation and hypothesizing about external existents is not
"metaphysical" if the hypotheses have testable consequences. They are
then theoretical. The bare-bones UR is the only metaphysical posit
required to do science. If further metaphysical speculation regarding
phenomena within the domain of science (the existence, content, order,
and behavior of the ER) has some other purpose, that purpose escapes me.

Perhaps it comes down to, "What suffices to alleviate perplexity?" No
doubt the answer to that will vary widely from person to person.

I'm pretty sure that conclusion is based on your identification of a
posit with the thing posited. That error construes the atom (for
example) as an "idea within the ER." Hence there is no external entity
available to supply a cause for the ER, and thus no escaping the
chicken-and-egg problem.

*An* order is a precondition. The *particular order observed* within the
ER requires explanation. And order has no existence apart from its
various manifestations; there is no "order itself." That is a Platonic
notion.

What renders it killable is the absence of any *possibility* of evidence
for or against it, consistent though it may be.

Describing the structural and compositional requirements for systems

Well, depends on what you think the question is. I take it to be the
puzzle of why some systems are conscious and others are not. If you
assume everything is conscious, then that puzzle is certainly solved, or
rather, dissolved. But the striking differences between those systems
previously considered to be conscious, and those considered not to be,
remain evident, and just as striking. We still have to account for them.

That is evasive, Andy. The claim is that an hypothesis may be dismissed
if it is not open to investigation (it is noncognitive). If you claim
that it is open to investigation, then it is up to you to outline how
that investigation may proceed, given the absence of any possible
consequences to investigate. "The burden of proof rests with he who
holds the affirmative." The answer to that question is very much
relevant to whether the hypothesis *should* be rejected.

We cannot observe such X's as electrons, quarks, gluons, "dark energy,"
etc., etc. Are you saying we can't do science with them?

Possible X's which have empirical consequences are not "metaphysical
X's." They are instantiations of an entity posited metaphysically,
however.

It is identical if no differences between the two can be discerned or
specified. You then have a distinction without a difference. I don't
mean *numerical* identity, here, of course, but identity of type --- the
type being that defined by some *verifiable* criteria for a "conscious
system."

(A number of counterexamples have been proposed for Leibniz's II
principle, but none of them would cover the present case).

It does need a defense, which I just gave. But if you presume there is a
difference deriving from some non-verifiable property which one system
possesses and the other does not, then there is probably no point to
further debate. Such a debate is fruitless, because the thesis asserted
is noncognitive.

There is no "knowledge of" an act of experiencing, unless you're merely
referring to a memory of an experience. An episode of experience is an
episode of learning, i.e., of knowledge acquisition. They are the same
thing.

And a conscious system does indeed begin experiencing using a mechanism
it does not understand, and cannot specify, at the time it begins
experiencing. But that does not preclude it from eventually puzzling out
that mechanism.

Not all infinite regresses, BTW, are vicious. They are not vicious if by
explaining one step, you explain them all. I.e., if we can explain how P
knows A, then we will likely also have explained how P knows that he
knows A, etc.
