Yes. The categoricity proofs by Hilbert, Dedekind and others would today
be said to establish the categoricity of certain second order theories.
There are also categorical first order theories.

Imho, formally, it's near impossible to *directly* define "absolute

that is relative is not absolute, then we have a good chance to
indirectly understand "absolute truth". And relativity is something
we could easily define upanddown the ladder of mathematical
introspection. For instance, the truth of 1 + 1 = 0 is relative
to what formal system we choose, hence it can't be an absolute truth.
Or the truth of (x=x) would depend on what logical system that's being
assumed, hence it's not an absolute truth. etc...
Imho, mathematical relativity could be grouped into 2 groups:
a) interpretation/semanticbased relativity: this is when a truth value
would depend on a reasoning being's (model) interpretation, or
(semantic) interpretation.
b) knowledgebased relativity: this is when knownability of the truth
value would depend on the knowledge on the reasoning being. For
instance, without loss of generality, let's k be a number so big
that Prime(k) is unknown to human being, then Prime(k) is knowledge
relative. (If the theory is PA, then it's possible that PA can be
inconsistent and in which case Prime(k), for there would be no
model. But PA's shortest inconsistencyproof might be even
longer than proof of Prime(k). Hence "Prime(k) is true" is a
knowledgebased relative truth.)
And again, the truth that is relative is not an absolute truth.

All right, so this is one way of understanding what "absolute truth"
means. On this interpretation, in my view the question about whether
absolute truth exists is trivial. It is obvious and uninteresting that
no sentence can be true regardless of which semantics we use.

I wouldn't go that far though.

Why not?

I am predisposed to be persuaded) that if a school of mathematicians
got into the habit of saying that sort of thing (while continuing to
do mathematics) then we (and possibly they) might want to say that
what they were doing (though still mathematics, and possibly very
fine mathematics) was no longer "number theory" (or, weaker, no longer
*just* "number theory"): but I don't see such a response
is selfevidently right.
That certainly would be the natural reaction. In fact, there already is
a discipline of mathematics where one can expect to hear such things. No
one calls it "number theory". It seems highly unlikely that there ever
could be a school of mathematics in which studying e.g. structures in
which the arithmetical consequences of ZFC hold was called "number
theory". That sort of a terminological shift would require a major
upheaval in the way people think about natural numbers.
In other words (I guess), is there anything more than historical
chance and prejudice behind the feeling (which I certainly share,
but don't feel particularly justified in sharing) that "natural
numbers should be *categorical*, dammit"?
It's a basic property of our conception of the natural numbers that they
don't bifurcate into a multitude of nonisomorphic structures. There are
some people of ultraintuitionist and ultrafinitist peruasion 
EseninVolpin and Edward Nelson come to mind  who do think that there
are many different natural number lines and reject the ordinary
conception of the natural numbers as incoherent or unjustified. This
just goes to show, once again, that it is to a large extent a matter of
personal preference and inclination what one finds convincing and
coherent, and that even in mathematics there probably is no principle
someone competent hasn't doubted or rejected.

I consulted the web site ``Earliest Known Uses of Some of the
Words of Mathematics", for which I can't find the author.

Not in any respectable logic it doesn't. According to de Morgan's laws,
"not (P and not P)" is logically equivalent to "P or not P".
It may be equivalent to lots of things. The issue is whether it
converts into itself mechanically.
According to de Morgan, and others,
"not (P and not P)" and
"P or not P"
convert quite mechanically into each other but
"not (P and not P)" and
"not P and P"
do not convert into each other in any way at all.
I get dizzy just trying to read all this

Then you have no business trying to deal with formal logic, as this is
quite simple compared to most of it.

What is "truth"?
I can deal with the tautologous logical truth of implications like "if P
then (P or Q)", but other than those, which include the more complex
logical deductions from a set of axioms, I know of no absolute truth.
If we care to consider absolute truth, then there is no such
thing as an absolute truth.
Well thanks for the input. Can we take your word for this?
I don't see why not, unless an absolute truth could be demonstrated
to exist! Would
(1) (P => (P \/ Q))
constitute an absolute truth? Well, at this moment for some odd reason
"\/" to me means what "/\" means to a lot of people (and vice versa for
"/\")!. So (1) to me is not a truth; so it can not be an absolute
truth that *must be universally recognized without exception*!
If "absolute truth" means "something that is true regardless of which
semantics you use" then you're right, no absolute truths exist. This is
not a very interesting point.
I agree it's not a very interesting point since you assume this truth
absolute.
No, I don't. I certainly don't assume it absolute in Nam Nguyen's
sense. Clearly no truths are absolute in that sense.
Oho?
What I said was true relative to the semantics I was actually using. It
clearly would not be true relative to any conceivable semantics. This
is trivial.
Certainly it seems so to those prefer to deal in assumptions of truth
and assume so.
No "seems" about it. It's completely obvious. What contestable
assumption do you think I'm making?
I didn't say "contestable assumption". What I said was "assumption".
Assumptions refer to a lack of demonstration.

In some contexts, perhaps. In some contexts I would have thought it
also implied that there was some room for reasonable doubt.
Quote:  You certainly assume
what you don't demonstrate by calling it obvious.

It is obvious to any person of good sense.
Quote:  Obviously it is a
canonical assumption on your part that what you say is true. Whether
it is actually true or not however remains to be seen.

You have some doubt about it, do you? Would you like to elaborate on
this?
Quote:  I think people who talk about absolute truth usually mean something
different to what Nam Nguyen thinks it means
Not at all
What's your evidence?
If you would be so good as to clarify what Nam thinks "absolute truth"
means I'll try to supply it.

As I said, Nam Nguyen seems to be using "absolute truth" to mean
"something that is true independently of which semantics we use".
Obviously no such thing exists.
Quote:  It may or may not be "different to" what
others think but I have no doubt it will be "different from" what you,
Nam, and others think.
if I intuit your point correctly. The claim I make is
intended literally and exactly.
What claim?
What claim were you referring to?

When? I can't see where I mentioned any claim. Quote me referring to a
claim and I'll tell you what claim I was referring to.
Quote:  We seem to be in a "he said/she
said" mode at this point where it's difficult to discern what each of
us is referring to. My claim in general terms is that the alternative
to absolute falseness is universally true.

What do "absolute falseness" and "universally true" mean?
Quote:  , and I make no comment
about whether absolute truth exists in on of these senses or whether
what I said was absolutely true in one of these senses. I merely claim
that it was true.
That is: not even "tautologous logical
truth" would be absolute.
Yes but tautological alternatives to necessary and universal falseness
would perforce have to be necessarily and universally true.
Again, as has been questioned by another poster, what does "universal
falseness", or "universally true" mean?

Right. That's why it seems interesting (to me) that occasionally there

truth!
I think when these debates take place people are usually getting
interested in absolute truth in a different sense to the sense you're

Would you be able to give a specific example of another different
sense, in which an *absolute* truth could be defined and be interested
by *more than one person*?
Universal truth, truth mechanically contrary to universal falseness?

In the context of math and logic discussion, when we say *specific
example* we mean a specific mathematical statement of certain
specific logical framework (meta statement would be OK too). Just
_simply uttering_ "Universal truth", "universal falsenes", "truth
mechanically contrary to universal falsenes" doesn't make these
specific examples or anything meaningful, other than nonsensical
babbling.

A claim which means nothing, unless Zilch can establish that there is an
absolute falseness. Is that anything like establishing that "Satan"
exists?

In your case yes. If you can't even analyze the general claim you're
much better off in faith based set theory.
