And you're wasting our time. So what? Hasn't stopped you so far.

So this absolute truth thingie, Tony. Does it lie out there in space
with the conjunctions you hypothecate and the dimensions Ben
hypothecates? Can we conduct some experiments to demonstrate what you
claim? Or are we forced to rely on your and Ben's philosophical tracts
on these subjects instead? I'm inclined to the incontrovertible
opinion personally there are three plus or minus 1/2pi dimensions,
seven plus or minus 0.01 conjunctions, and two plus or minus e
absolute truths but one can hardly ever tell for sure I suppose. Oh
and don't forget the "is is" principle of Isis nee Parmenides. I'm
sure we'll have to make room for it somewhere out there in space too.

Well, Tony, my problem comes with your apparent inference that 1=not 0
and 0=not 1. That can only be true in the context of TvN assumptions
and mechanics where no intermediate values can exist and the physical
constraints on bit representations in the system assure it. Otherwise
you have no strict binary mechanics and representations both within
and outside the limits 0-1 are possible. So either your mechanics is
binary and non probabalistic or probabalistic and non binary. I don't
see there is any other possibility.

Not really, Tony. I'm just trying to point out that the truth of
combinatorial predicates is inherently problematic and not
probablistic one way or the other.

Let's suppose we ask whether the proposition "large green apples are
large red apples" is true? The proposition itself is obviously false
and on that basis should warrant a truth value of 0. But when we
assign a truth value to a proposition the question is how do we do it?

The fact is two of the predicates are true and one false. Does that
mean t=0.000 or t=0.667? The same would apply to combinations of
propositions. Are we supposed to be taking an arithmetic average or
exercising some kind of intuitional insight? Not even to mention the
weighting of predicates. I just can't imagine that all predicates have
the same significance in terms of probablistic truth. Are we supposed
to just adopt someones weighting opinions on the subject of truth?

Except, Tony, your references to logic are all over the place.

Where are these boolean conjunctions supposed to be? I've already
shown there are no boolean conjunctions in strict mechanical terms and
the only possible conjunction is "not" and compounding of "not".

Then when you willy-nilly appeal to TvN binary logic you can't even
show how you can accommodate both unambiguous truth values and
probabalistic values in one scheme.

I mean you can't have it both ways, Tony. Either your mechanics is TvN
binary and non probablistic or probabalistic and non TvN binary. And
just saying machines do it just fine doesn't mean you can have it both
ways.

What I doubt is that your "no reason to doubt" is not the same as the
truth you claimed to have proven. I don't doubt that x can be 4 but I
doubt that you've shown x is 4 or x must necessarily be 4 when all
you've shown is that x can be 4 under certain assumptions of truth
when you haven't demonstrated the truth of those assumptions of truth.

I wonder if you really understood what I was getting at with my essay
on truisms and the nature of Aristotelian syllogistic inference? When
we have problematic circumstances we can certainly say "If A then B".
But that doesn't allow us to conclude "A" definitely is. And Aristotle
had a great deal useful to say about the evaluation of truth given the
facts of truth to begin with but he could never establish the fact of
truth itself to begin with nor why and how facts of truth were true.

And when I say "truth" and "demonstrations of "truth" I'm talking
about "truth" and not merely "truisms" such as "If A then B" whereas
what you and the rest of mathematics insist on talking about are
truisms such as "If axioms are true and our assumptions regarding
logic are true then theorems are true" and "If boolean assumptions
regarding truth and conjunctions and so forth are true then truth
values etc. are true" and so on.
