We are getting more coherent and on point in our understanding of each
other. ;-) Interleaving.

But there is no such thing as a delay in Platonia, but that is not my
point. I am trying to see how you deal with the problem of intractible
computations - as implementable given infinite resources - and how it may be
possible for measures to be defined using them. I had not considered this
application but it is intriguing. You touch on this below.

Yes, but is this derivation on that can be taken to exist independent of
the first person aspect of comp histories?
This may be one of my key difficulties. On one hand, I do not have a
problem with the idea of Platonic existence, re AR, of mathematical objects
but I do have a problem with the seeming lack of a clear explanation of how
the "flow of temporality " arises in the first person aspect.
It seems to me that what ever our theory of Everything is, it must
explain how it is not just possible to have a "flow of temporality" a
priori; it must have a non-measure zero sampling in the class of all
possible relationships between numbers - or whatever notion of Ur-object
that one uses.
I personaly eschew the notion of fundamental "objects" and use the
Heraclitian notion of Process and fundamental, thus I see mathematical
objects - numbers, etc. - as derivative of this notion of Process. I see
Hintikka's idea of proofs as game theoretical constructs as strongly hinting
at this idea...

I agree. We have to have the methodology itself as an a priori existent.
It is co-present in Platonia in your thinking, it seems to me. ;-)

Wait a minute! It is one thing to say that "[whatever]-truth is not
[whatver]izable" and it is another to say that [whatever]-truth is finitely
constructible or approximatable. The former deals with its existential
aspects and the latter deals with its meaningfulness and expressiveness. We
do not require absoluteness (truth, decidability or otherwise) in our
interactions to be able to have meaningfulness.
But this is not problematic to me; I am interested in how physicality
MUST obtain, even if only in the first person sense. In fact, in my work I
anly assume first person physicality - there is no such thing as third
person or "objective" physicality. This is where our idea overlap

I have been following your discussion with Kory (and all others)
In an attempt to "put all my cards on the table" I will state that my
idea is a kind of process based mind-body dualism (based on Vaughan Pratt's
work http://citeseer.ist.psu.edu/pratt95rational.html), but one that becomes
very similar to Russell's "neutral monism" in the limit of "the Totality of
Existence", which I believe is the same as your Platonia, e.g. an
"asymptotically vanishing dualism. I do not see Platonia as being "mental"
or "mind", ala a new form of Berkeliean Idealism.
