Matheology § 258

So what about Cantor’s much celebrated non-denumerable real? Where is
it? Did Cantor produce such a real number? No, he merely sketched out
the logic for a nonterminal procedure that would produce an infinitely
long digit string representing a real number that would not be in the
input stream of enumerated reals. Cantor’s procedure, and with it his
celebrated nondenumerable, infinitely long real number, will appear
with 100% certainty in the denumerable list of procedures. {{That's
the point: Every diagonal number can be distinguished at a finite
position from every other number. But if all strings are there to any
finite dephts, as is easily visualized in the Binary Tree, then there
is no chance for distinction at a finite position - and other
positions are not available.}}
There is no non-denumerable real, and every source of real numbers
is denumerable [...] Implications throughout mathematics that build
upon Cantor’s Diagonal Proof must now be carefully reconsidered.
So Who Won? Professor Leopold Kronecker was right. Irrationals are
not real {{ - at least they have no real strings of digits, and only
countably many of them can be defined in a language that can be
spoken, learned and understood}}. God made all the integers and Man
made all the rest {{and in addition something more - unfortunately.}}

I was thinking that if we pin down the standard model then there will be no infinite numbers, no infinite proofs and no infinite strings. But if there are no infinite strings ... Well, it seems to me that the set of all the subsets of N has to interpreted as the set of all finite subsets. After all the elements of N are finite. It also seems to me that that this is what potential infinity means: a set is potentially infinite if all its elements are finite.

Of course, it is impossible to pin down the standard model (is it?). Any attempt to do so results in a contradiction, and then they say there is no model at all. This comes from the same folks who swear that Goedel's sentence is NOT paradoxical, hell no! Needles to say they have all the logic backwards. The standard model cannot be pinned down because Goedel's sentence IS paradoxical. Is there any way around? Hell no! (Or is there?)

Deliberate misrepresentation, as usual from WM.

It is not any one real number which is non-denumerable, it is the
collection of all of them that cannot be denumerated (put into bijection
with the naturals).

Such deliberate misrepresntataion is typical of the anti-mathematics of
WM.

Get out of the 19th century (or 17th)

Evolutionary History of the Real Numbers" in S. Levinson, & P. Jaisson
(Eds.) "Culture and evolution"

<abstract>
The cultural history of the real numbers began with the positive
integers. Kronecker is
often quoted as saying, "God made the integers; all else is the work
of man," by which he
meant that the system of real numbers had been erected by
mathematicians on the
intuitively obvious foundation provided by the integers. Taken as a
statement about the
cultural history of mathematics, this is beyond dispute. But if this
is taken as a claim
about the psychological foundations of arithmetic reasoning, then we
suggest that here, as
in many other areas of psychology, introspection and intuition are
poor guides to the
inner workings of the mind.

We suggest that it is the system of real numbers that is the
psychologically
primitive system, both in the phylogenetic and the ontogenetic sense.
We review evidence
that a system for arithmetic reasoning with real numbers evolved
before language evolved.
When language evolved, it picked out from the real numbers only the
integers, thereby
making the integers the foundation of the cultural history of the
number. Secondly, we
suggest that this ancestral non-verbal real number system becomes
operative in the
prelinguistic child and makes possible the acquisition of language-
mediated counting and
language-mediated arithmetic reasoning. It is the foundation on which
an individual’s
language-mediated understanding of what numbers are and what may be
done with them
rests.

Nobody can read, write or use an infinite string.
Real numbers are represented by *finite names* that allow to
*calculate a rational approximation up to any desired digit*. This is
generally called a potentially infinite sequence (of approximations)
and often mistaken as an infinite sequence. But it is not the same as
an actually infinite string that defines, by sequence of digits, a
real number without doubt.

No string of digits, without a finite formula to generate it, defines
an irrational number.

Too bad WM does not know what mathematics is presupposed
to make such calculations that require a presumed
exact value against which error is minimized.

=============================================

WM's "logic":

http://en.wikipedia.org/wiki/The_Art_of_Being_Right#Synopsis


WM's "mathematics":

WM is an unabashed ultrafinitist who refuses to fix
a largest finite number. Each "n" in his description
depends on the subsequence of triangular numbers.

> F(n)=Sum_i(1..n)(i)
>
> 1 :=> 1
> 2 :=> 3
> 3 :=> 6
> 4 :=> 10
>
> and so on

According to Brouwerian intuitionistic reasoning,
when WM's construction reaches the point where
the sequence of triangular numbers exceeds the
ultrafinitist limit, the contradiction nullifies
the construction.

This is WM's model of mathematics:

http://en.wikipedia.org/wiki/Finite_model_property

until he reaches his contradiction and
it vanishes.

=====================================

The triangular numbers correspond with
the number of 'marks' representing numerals
or significant denotations occurring in any
of WM' representations of the form:

1
2, 1
3, 2, 1
...
n, ..., 3, 2, 1
...

-------------------------------------

This number of 'marks' satisfies a structural
feature of the natural numbers called a
directed set:

Defintion

A binary relation >= in a set D is said
to direct D if and only if D is nonempty
and the following three conditions are
satisfied:

DS1)

If a is an element of D, then a>=a

DS2)

If a, b, c are elements of D such
that a>=b and b>=c, then a>=c

DS3)

If a and b are elements of D, then there
exists an element c of D such that c>=a
and c>=b


So, WM's geometric reasoning for any given
n obtains a finite model domain with its
cardinality given by the associated
triangular number. The triangular number
is the "element c" of condition DS3 from
the definition.

-------------------------------------

Finally, Brouwer's explanation for finitary
reasoning is used because WM refuses to
commit to any mathematical statement with
coherent consistent usage.

Brouwer distinguishes between results with
regard to 'endless', 'halted' and
'contradictory' in his explanations

"A set is a law on the basis of
which, if repeated choices of
arbitrary natural numbers are made,
each of these choices either
generates a definite sign series,
with or without termination of the
process, or brings about the
inhibition of the process together
with the definitive annihilation
of its result."

WM cannot be an ultrafinitist and
expect others to not hold him to
task for it. In constrast to
Brouwer, he repeatedly states
that there is absolutely no
completed infinity. Therefore,
there must be a maximal natural
number for his model of
mathematics. Beyond that
number, there is no mathematics.

That is WM's belief as surmised
from his statements and reasonings
as opposed to what he says with
rhetoric.

says a total flop who failed to overcome even the lowest academic

mathematics at German universities for about 25 years and has
published a math best seller in the country of Leibniz, Gauss and
Cantor with the publisher of Hardy, Feyman, Oberth, Diesel ...

Sorry, WM, but you have proven beyond any doubt to be a complete,
pathological, pathetic crank.

The fact you're teaching in Germany is INDEED a real problem for
Germany!

Please, don't involve Leibniz, Gauss, and al. with your dementia.

Certainly WM cannot, but there area all sorts of mathematical things
that WM cannot do but real mathematicians do quite regularly, like prove
their claims.

How do such finite names as "pi", "e", "sqrt(2)". etc.,
"allow to calculate a rational approximation up to any desired digit"?

One can use infinite strings, just like other sorts of infinite
sequences, by name or by other reference even if one cannot write them
out completely.

The names might be COMPACT (WM really should learn
the difference), but what is presupposed by
Leibniz principle of identity of indiscernibles
is a different matter:

"All existential propositions, though true,
are not necessary, for they cannot be
proved unless an infinity of propositions
is used, i.e., unless an analysis is
carried to infinity. That is, they can
be proved only from the complete concept
of an individual, which involves infinite
existents. Thus, if I say, "Peter denies",
understanding this of a certain time, then
there is presupposed also the nature of
that time, which also involves all that
exists at that time. If I say "Peter
denies" indefinitely, abstracting from
time, then for this to be true -- whether
he has denied, or is about to deny --
it must nevertheless be proved from the
concept of Peter. But the concept of
Peter is complete, and so involves infinite
things; so one can never arrive at a
perfect proof, but one always approaches
it more and more, so that the difference
is less than any given difference."

Leibniz



WM has been asked to provide coherent systems of
logic against which to judge his statements.
Instead, he uses the axioms he denies and the
principles he rejects.

There is no bound. But if someone claims that smallest infinity is
called aleph_0, then it is easy to prove that there are not more than
aleph_0 finite words.

Of course, but it is not an infinite string.
Infinite strings do not exist in the internet, because computers and
their personnel are much more rational than matheologians.
Names of infinite strings are countable.

If one had to get hold of actual numbers to do mathematics, there could
be no mathematics at all.

And it is the axiom system for the field of real numbers which implies
uncountability, not the naming of numbers.

The evidence for uncountability does not rely on being able to name
uncountably many individuals.

But, didn't you just dream of them in your philosophy? Or, is your
theory incomplete, or inconsistent?

Having just put a name on all of them, congratulations: there's
more. Basically Burali-Forti: Ord is irregular.

Well-order the reals, via Fefermann V = L, the universe as
constructible has for each element: that's its own name. Are the
reals a set?

The evidence for uncountability relies largely on constructive
proofs. And, the arguments for uncountability of the reals don't
apply to EF the natural/unit equivalency function.

Arguments for uncountability of the reals don't apply to EF: putting
the elements of the unit interval in a row, while satisfying notions
such as continuity, has range R_[0,1].

Bring forth applications of transfinite cardinals. EF has application
as the unit line segment.

"Non-denumerable real" is meaningless. Cantor proved that the set of reals is non-denumerable.

WM once again displays his profound misunderstanding and
misrepresentation of Cantor's position.

It is only a set whole large of reals which can achieve uncountability,
not a single real, as WM implies above.

What Cantor showed was that certain sets, including the members of any
real interval of positive length, cannot be put into one-to-one
correspondence with the set of naturals without leaving some of the
non-naturals being left over unaccounted for.

This is from the article which WM quotes.

Let us demonstrate that Cantor’s non-denumerable “real” is not real in another way. Let us assume, as Cantor did, that an enumeration E of the reals exists and that an infinitely precise, new decimal expansion can be created by changing the nth digit of the nth enumerated real. Let us designate this new real number as g, which will not be in E, hence the reals will not be denumerable.
Let us then create a second parallel output stream called h, created in an identical manner as g, with one small alteration: one randomly selected digit of h will be replaced by a random digit, so, with probability 0.9, g ≠ h. Now g ∈R and h ∈R,
and R is an ordered field, so g and h must be able to be ordered by comparing digits as they are generated, or they are not real. Let g(n) denote the nth decimal place of g, and let h(n) denote the nth decimal place of h. €


My thoughts here are that when the random digit is selected, ( his terms ), it's place
is certain. By that, I mean that it is not determined to be a m-th place, but it is certain
that it must be some n-th place.

I realize that the concepts of determined and certain need to be clarified.
However, I beleive they are sufficient for my arguments.
I will alaberate further if asked.

The same argument goes for choosing a random number for g(n).

Basically, I believe when he says, "randomly selects", we would say,
"arbitrarily choose".

The author continues:
If g(n)=h(n)for 0≤n≤k,but g(k+1)<h(k+1)
then we can conclude that g < h. Similarly, if g(n) = h(n)
for 0≤n≤k , but g(k+1)>h(k+1), then we can
conclude that g > h. €€
But to establish g = h, it must be true that g(n) = h(n) €€
for 0≤n≤∞.Thusinthe10%ofthetimethat g=hand €
k is unknown, the output streams will generate digits forever
wi€thout resolving the order of g and h. So these two “reals” g
and h €cannot be ordered, so g€∉ R and h ∉ R. Thus
infinitely precise digit expansions are not real. Irrationals are
not real.

He says, now basically, that since we can't know for sure
at which point the equality of g and h fails, or even if it fails
at all; then tricotomy fails and g and h are not "real" real numbers.

However, we do know that I'd the randomly select digit is equal to
the value of the digit at the randomly selected place in g,
then g = h.
OTOH, if the randomly selected digit is not equal to the value of the
digit at the randomly selected place in g, them g ~= h, where the
equality fails in accordance to the values of the digit in the randomly
place in g and the randomly selected digit.
Therefore, g and h can be ordered in any case.
The probabilities are irrelevant.

Thus, the proof is crap.

Any thoughts WM?

PS The randomly selecected and yet unknown number reminds
of WM's unfindable line that contain all natural numbers.

You are confusing "Given certain information, we would not be in a position to determine in a finite number of steps whether or not g=h" with "It is indeterminate whether or not g=h". These are not the same thing.

(1) Cantor proves that any list of reals does not contain the first n
digits (d_1, ..., d_n) of the diagonal d in the first lines (l_1, ...,
l_n).

For every n in |N. Nothing less, nothing more!

(A1) By assuming that the list can be finished, he concluded that d is
not in the list.

(2) This can be countered by the fact that every list containing all
rational numbers (which is possible, since they are countable)
contains in the lines beyond l_n infinitely many numbers starting with
(d_1, ..., d_n).

For every n in |N.

This is not in contradiction with what Cantor proved, but there is no
reason to believe that his assumption should have more weight than the
contrary assumption:

(A2) The list cannot be finished. (2) remains true in all cases.

A sequence of randomly selected digits will never led to an irrational
number, since every digit belongs to a finite initial segment of a
sequence of digits.

See my answers to Rupert. All lists that ever can be defined in the
universe belong to a countable set (finite by material constraints but
at most countably infinite by logical constraints (countability of all
words)). So do the substitution rules. No proof of uncountability in
sight.

Cantor's theorem is a theorem of RCA_0. As a corollary of this, the real number not in the denumerable sequence of real numbers may be given as a recursive function of the denumerable sequence of real numbers. You can make sense of the notion of a recursive function even when the argument may range over a set which has uncountable cardinality. For example, suppose I am given an "oracle machine" which will tell me the n-th digit of the binary expansion of the m-th number in the list. Then I can construct a Turing machine which will give me the n-th digit of the real number not in the list, provided that this Turing machine is allowed to make a call to the oracle machine when it needs to.

If the list itself can be recursively specified, then there is an effective procedure for obtaining a recursive specification of the real not in the list.

There are aleph-null different ways in which one could give the real number not in the list as a recursive function of the list.

The number of possible lists is c, the number of possible ways in which the real number can be given as a recursive function of the list is aleph-null.

If you restrict your attention to recursively specificable lists then the number of possible lists will only be aleph-null. But in that case the real number obtained will necessarily be a recursive real, so there will only be aleph-null possibilities for the real number obtained.

Before WM attempts to introduce "science" into his
justifications for these questions, realize that
actual scientific theory is not involved. WM's
arguments underlying these questions are a philosophical
position nicely summarized by Chris Menzel:

http://plato.stanford.edu/entries/actualism/

It also has a link for criticisms of the position:

http://plato.stanford.edu/entries/actualism/


----------------------------------------------------

WM's "logic":

http://en.wikipedia.org/wiki/The_Art_of_Being_Right#Synopsis


WM's "mathematics":

WM is an unabashed ultrafinitist who refuses to fix
a largest finite number. Each "n" in his description
depends on the subsequence of triangular numbers.

> F(n)=Sum_i(1..n)(i)
>
> 1 :=> 1
> 2 :=> 3
> 3 :=> 6
> 4 :=> 10
>
> and so on

According to Brouwerian intuitionistic reasoning,
when WM's construction reaches the point where
the sequence of triangular numbers exceeds the
ultrafinitist limit, the contradiction nullifies
the construction.

This is WM's model of mathematics:

http://en.wikipedia.org/wiki/Finite_model_property

until he reaches his contradiction and
it vanishes.

=====================================

The triangular numbers correspond with
the number of 'marks' representing numerals
or significant denotations occurring in any
of WM' representations of the form:

1
2, 1
3, 2, 1
...
n, ..., 3, 2, 1
...

-------------------------------------

This number of 'marks' satisfies a structural
feature of the natural numbers called a
directed set:

Defintion

A binary relation >= in a set D is said
to direct D if and only if D is nonempty
and the following three conditions are
satisfied:

DS1)

If a is an element of D, then a>=a

DS2)

If a, b, c are elements of D such
that a>=b and b>=c, then a>=c

DS3)

If a and b are elements of D, then there
exists an element c of D such that c>=a
and c>=b


So, WM's geometric reasoning for any given
n obtains a finite model domain with its
cardinality given by the associated
triangular number. The triangular number
is the "element c" of condition DS3 from
the definition.

-------------------------------------

Finally, Brouwer's explanation for finitary
reasoning is used because WM refuses to
commit to any mathematical statement with
coherent consistent usage.

Brouwer distinguishes between results with
regard to 'endless', 'halted' and
'contradictory' in his explanations

"A set is a law on the basis of
which, if repeated choices of
arbitrary natural numbers are made,
each of these choices either
generates a definite sign series,
with or without termination of the
process, or brings about the
inhibition of the process together
with the definitive annihilation
of its result."

WM cannot be an ultrafinitist and
expect others to not hold him to
task for it. In constrast to
Brouwer, he repeatedly states
that there is absolutely no
completed infinity. Therefore,
there must be a maximal natural
number for his model of
mathematics. Beyond that
number, there is no mathematics.

That is WM's belief as surmised
from his statements and reasonings
as opposed to what he says with
rhetoric.

By assuming that the Euclidean algorithm for
long division can be finished, every quotient
has an exact value.

It has been demonstrated that WM cannot tell the
difference between singular terms and plural terms
in his own grammar. There is no reason to believe
WM can comprehend it in mathematical statements.

WM is not allowed to invoke completed
infinities in his arguments.

On the one hand, he denies them. On the
other hand, his use of them for the purpose
of "proving contradiction" is invalid since
he makes no such argument within defined
parameters of standard mathematical logic.

Cantor's argument is misrepresented once
again.

The argument only applies where a claim
is made concerning the completion of a
list. It does not claim a complete listing
of real numbers.

We could be in a position where we cannot specify in advance a finite upper bound on the number of steps it will take to verify that they are equal. The usual stance of mathematicians these days is not to worry about the method of verification, but just the mathematical reality.

As a corollary of this, the real number not in the denumerable sequence of real numbers may be given as a recursive function of the denumerable sequence of real numbers. You can make sense of the notion of a recursive function even when the argument may range over a set which has uncountable cardinality. For example, suppose I am given an "oracle machine" which will tell me the n-th digit of the binary expansion of the m-th number in the list. Then I can construct a Turing machine which will give me the n-th digit of the real number not in the list, provided that this Turing machine is allowed to make a call to the oracle machine when it needs to.

And I can tell you inifinitely many numbers with the same criterion
(namely having the first n digits in common with that number that is
not in the list).

If the list contains all rational numbers, then there is no chance to

Correct, aleph_0 - and not more. So there are at most aleph_0 numbers
that are not in the list and yet can be given.

All other "real" numbers are not real in the sense that they ever
could be applied in any way in mathematics as individuals. They can
never act as diagonal numbers, they can never enter a calculation and
they can never appear as a result or as an intermediate result. In
brief: They do not exist in real mathematics and elsewhere.

Of course that is not claimed. Otherwise Cantor would contradict
himself.
Claimed is completeness of the list with respect to the natural
numbers enumerating its lines

His proof assumes that every line of the list can be looked at (or put
into a CPU of a computer) such that no line remains. But that
condition is wrong, since for every line there are infinitely many
following. If all rationals are in the list, then we have:

Forall n: (d_1, ..., d_n) is repeated infinitely often in the list.

No, that does not follow. There are aleph-null different ways to define a recursive function from lists of reals to reals which always give you a real not in the list. But, for any given particular list, it will always be the case that there are more than aleph-null reals not in the list, because not all of them have to be given by such recursive functions.

Depends what you mean by "diagonals".

The point is that the set of all reals is not countable.

That's false, there are plenty of non-computable reals which are still arithmetically definable, for example. And whether a real number can be defined in a particular language is neither here nor there so far as the "reality" of the real number is concerned.

No. What is a possible list? That is a list that can be defined in
some way. But since you cannot define an infinitude of lines by an
infinitude of definitions, you need a finite definition for a list.
Only then it can be possibly used, investigated, and discussed.
Therefore the number of possible lists in mathematics is aleph_0.

Once again, Cantor's argument is misrepresented.

concerning the completion of a list WITH RESPECT TO A SINGULAR

I find your remarks humorous.

First, you are the one who has called me a parrot,
a deplorable slave, a coward, etc.

So rot in hell.

When I gave you the opportunity to address a
properly formulated non-standard theory, you were
the one who behaved like a coward.

In fact, with every opportunity given to you in the
past by anyone you have behaved similarly.

You are the one spamming an unmoderated newsgroup
with your agenda. You are the one insulting
people. And, although not anonymous, you are the
one with a professorship who cannot get these
views of yours published in a respectable peer
reviewed journal.

When confronted by someone concerning your "theory"
and any reason for paying attention to it, I had been
directed to your "papers" on arXiv. I expect that they
will be removed once my complaint to the moderators is
received. They have a stated policy concerning the
publication of relevant, scientific documents. It
will be surprising if your nonsense survives review.

I know that no one who pays regular attention
to your nonsense threads will have any reason
to read the postings I make. On the other hand,
it is important that a casual observer recognize
how you engage in mathematical discourse is not
an appropriate form of argumentation.

So rot in hell.

Even if, for example, you were to work in RCA_0+"Every real is computable", Cantor's theorem would still hold. It would tell you that given any computable list of computable reals there exists a computable real not in the list.

Better work in mathematics.
There the following theorem holds for every list that contains all
rationals numbers:
forall n in |N: The sequence (d_1, ..., d_n) is in infinitely many
entries of the list beyond line n.

Don't forget: For every natural number!
Don't forget: No real number can be defined by its infinite sequence
of digits. In every case a finite definition (like 1/9 or 0.111... or
sqrt2 or e or pi) is required.
You can distinguish a finite definition from an infinite sequence?

Of course it is mathematics. That is the way that mathematics is practiced these days.

Also, as pointed out elsewhere, even in the theory RCA_0+"every real is computable", Cantor's theorem still holds. In that context it says that given any computable list of computable reals there is a computable real not in the list.

That's changing the subject.

If I assume the axiom of choice then I can prove the existence of a choice set for the cosets of Q in the additive group of R, that's not the same as saying that I can define it.

And I can prove the existence of reals which are undefinable in any given countable language.

In mathematics, proof is the only means we have of knowing the nature of reality. But that in no way contradicts what I wrote. Because in modern mathematics we assume that the reality has a determinate character regardless of whether or not we can observe it, or what the method of observation is. For example, it is legitimate to speak of "the first natural number n such that there is a sequence of twenty 7's in a row in the decimal expansion of pi starting at the n-th digit after the decimal point, if it exists", regardless of whether or not we have any feasible means of determining what this natural number is. Or we can speak of "the ordinal alpha such that 2^(aleph_null)=aleph-alpha", even though it is impossible to determine on the basis of the axioms of set theory what this ordinal is.

Quite a lot, because I was talking about comparing two real numbers solely by means of inspecting finite fragments of their decimal expansions, whereas using the full power of what can be proved from an axiom system for mathematics might well go a long way beyond that.

I have no doubt.

There is legitimate mathematical insight associated
with your constructions. That you identify absolute
infinity with denumerability does make the Cantor
argument inapplicable in the sense that the Cantor
argument requires that a presumed totality be given.

As noted before, however, there are appropriate
mathematical investigations into systems based on
those characteristics. And the same is true with
regard to philosophical investigations. You simply
pursue an agenda that disrespects all.

Consider the natural/unit equivalency function (so-called exactly for
this reason), with domain N and co-domain R_[0,1]. This is n/d for n
from zero to d and d goes to infinity.

f_d(n) = n/d, 0 <= n <= d
f(n) = lim_d->oo lim_n=0^d n/d

The expansions of the elements have this feature: for each n, the
first n many elements of f(n) as .000[][][]... are zero, and, in
binary, the only value different from each has value one. The
resulting anti-"diagonal" has expansion .111... = 1, and lim_n->d n/d
= 1.

Then, besides that this function has properties as being a CDF, there
are considerations about representations in expansions with any given
integer radix, vis-a-vis the particular properties for the radix being
0, 1, or infinity. The elements of its range satisfy being elements
of the complete ordered field, just not that the operations are
interchangeable except through the projection onto R_[0,1], with an
extended definition of R (as sees initial development here on this
forum). As well there are other properties of this function of
interest for their novelty, with regards to the real numbers of the
natural continuum and their foundation.

So, there's an enumeration of elements of the unit interval, and:
with the elements of its range dense in the unit interval and
otherwise meeting continuity and being suitable as a prototype unit
for measure (and of a metric, etc.), the arguments for uncountability
(anti-diagonal, nested intervals, continued fractions as well) don't
apply to it.

That presumes that there cannot be unnamed numbers.

But that presumption is no part of real mathematics, however much

No, it is matheology. Three centuries ago, there were university

Please answer a question. What do you think is meaning of this fact:
For every n in |N: every list containing all rational numbers
contains in the lines beyond line l_n infinitely many numbers starting
with (d_1, ..., d_n).

This means: Cantor's proof does not say anything about the presence of
the diagonal number in such a list. In contrast we see that every
finite initial segment of the diagonal number is in the list. In
addition to believing in unthinkable thoughts and unusable numbers you
must believe that the diagonal number is more than all its finite
initial segments. But you know that you cannot define a real number by
more than all its finite initial segments.

Isn't that a bit too much nonsense that you have learned in your
"mathematics" lessons?

That is a problem only for those claiming that all reals can be
listed/counted.

If no such lists of all the objects in a set can exist then any set of
objects that cannot be so listed is an uncountable set by definition.

One such rule is enough, and at least one can be defined.

The Cantor argument presumes a countable totality. I accept this
assumption and show that the conclusion onto an uncountable infinity
does not follow.

Every Cantor-list that contains all rational numbers contains also all
FISs of the diagonal. In mathematics, the diagonal is nothing outside
of the sequence of all its FIS. The limit another thing. But the limit
is not in the list and is not the diagonal of the list.

One logical fallacy is certainly the assumption that the limit of the
finite segments of the diagonal is defined by digits.

Limits of rational sequences are not rational and are not defined by
digits.

Then there are actually infinite sets and the walls of Wolkenmuekenheim
have fallen before the horns of reason.

If the cardinality of the set of all lists is aleph_0, as conceded
above, what is the cardinality of the set of all sets of lists?

It must be at least as large, just from counting its one element sets.
Can WM prove that it is no larger?
That would require WM to do something like listing all sets of such
lists.

What are those d_n? if they are rationals taken in order from some list
of all rationals, then none of them need ever reappear beyond line n of
that list.

Actually, every real is definable by an infinite sequence of digits
along with a sign and a radix point position in the sequence and the
radix base value. The only problem is in finding which sequence.

But if a finite definition produces an infinite sequence of digits which
in turn defines a real, then that infinite sequence defines that real,
too.

But even to the most complete of such listings, as many more numbers
exist unlisted, so no list can be a complete list.

The number of NON-members of any such list is always at least one
so no such list is ever a complete listing of all reals.

Thus there is no counting process which can ever count all of them.

They are 'real' in the sense that the least upper bound and greatest
lower bound properties of the 'real numbers' do not work without them.

Nonsense. There is no sequence of digits that cannot serve as an
antidiagonal to a sutable sequences of reals.

If they do not exist, then neither do least upper bounds or greatest
lower bounds, and thus no real number systems either.

There always exists thoughts you haven't (at least yet) thought of .
The set of all thoughts is more than you can think at once (in one
thought) .
The set of all countable sequences is more than you can count at
once.

Give me a list of reals and I shall give you a number not on the list.
Any 'sequence of thoughts' you can give me still constitutes a 'single
thought' from you .
But the totality of possible thoughts is not within the gasp of a
'single thought' , thus , not amenable to sequence in thought.

Indeed , there cannot exist ideas that nobody can think , but the 'Set
of all ideas' is more than anybody can think .
Though does not follow a 'thinkable pattern' even if , the 'elements
of thought' , by definition , do .

If the list cannot never be finished the the set from which it is being
constructed is uncountable already.

Note that, outside Wolkenmuekenheim, countability implies listability:
A set is, by definition, at least outside Wolkenmuekenheim, countable
ONLY IF there is a surjection from |N to that set!
And is uncountable when there cannot be any such surjection!

Thus any set, for which no such surjection can exist, regardless of the
reason, is uncountable by definition!

The very definition of countability requires that a set be listable.
A set which is not listable in any way is also not countable.

Except in WMytheology, where all definitions bend to WM's will.

Only in WMytheology!

It is still the condition required by standard mathematics,

Cantor does not have to claim existence of any 'complete' list of reals.

Those who claim that the set of reals is countable are the ones who need
to prove a 'complete' listing of the reals in [0,1] CAN exist.

Cantor need only need show that ANY list of members of the closed
interval [0,1], and many incomplete such lists do exist, is necessarily
an incomplete listing of the reals in [0,1].

Which Cantor does! Neatly and unambiguously!

And all the obfuscations that WM throws up do not obscure the validity
of that proof.

To prove countability of a set S, one must prove a surjection from |N
to S.

So to show that the reals are countable, WM has to prove existence of a
surjection from |N to |R.

Cantor proved that no such surjection is possible.

And none of WM 's incessant counter arguments have established a
surjection from |N to |R.

So Cantor wins!

And in the conflict between Mathematics and WMytheology,

I agree, if you randomly select a digit for each place one at a time,
you will never fill every place.

However, we can prove in mathematics, by the use of logic,
that every real number, meaning every Cauchy sequence,
has at least one decimal expansion. We can also show that
every decimal expansion ( finite or not ) corresponds to
exactly one real number. Hence, these randomly selected
numbers are of no use.

I contend a string of randomly selected digit is not a real number.

Yes, again I agree, the set of all list must be countable. However,
this does not prevent us from defining sets whose cardinality is
uncountable. For example, we can define R, the set of real numbers,
as a complete ordered field. I can also define each and every rational
number, as well as, each and every algebraic irrational number
in a set that is at most countably infinite. We could also define that
entire set in a finite set of definitions. Either way, we still have
a countably infinite set of definitions leftover.
So this no hinderence to a proof of the uncountability of R.
As a matter of fact, a model of ZFC can even be contained in
A countable set. That is, if a model of ZFC exists.

Does a name like "James" itself have a name?
Maybe naming names is required in German, but not in English, and not in
mathematics.

There are lots of good ideas that WM cannot think, and far too many bad
ones that only WM ever thinks.

The limit of the rational sequence f(n) = 1/n, is certainly rational.

For every rational, q, with |q| < 1, the sequence
1, 1+q, 1+q+q^2, 1 + q + q^2 + q^3, ..., has a rational limit.

Wm must be a lousy mathematician to claim that
"Limits of rational sequences are not rational"

Out of curiosity, is that your stance, not to worry about method of verification.
I would, personally, agree. If we have a proof, in an presumed consistent setting, then that
is sufficient. I don't think every conjecture needs to be verified case by case, to find
it's truth value in a given system. Indeed, this impossible in most cases in mathematics.
Furthermore, if a certain apperatus is unable to verify a conjecure, then that is a limitation
of the apparatus, not the mathematical system.

Just for the record, I know little of Recursion theory or Computation theory.
Maybe the reason for my agreement with the stance above.
I can follow the simple terms, but when you state consequences, I have to
take you word for it.

Thanks.

I think I have solid line on some apples, ZG

The very definition of countability presumes a countable totality, or
more specifically, a surjection from |N to any set being claimed to be
countable.

Suppose WM claims that the set S, of binary sequences,
functions from |N to {m,w}, is countable.

The WM is claiming that there is a function, say f:|N -> S, which is
surjection.

So a claim of cuntability requires existence of a surjection and a proof
of uncountability only requires that any such caim be falsified.

Which Cantor did, quite nicely!

And not all of WM's wriggling can undo it.
