    Yes, and,
    when we discuss non.standard models,
    we can assemble claim.sequences which
    start with a description of a non.standard model.
    And, when we do that,
    augmenting true.or.not.false claims
    will be true about the described non.standard models.

    However,
    non.standard models of integers are not
    standard models of integers.

    Ah, yet according to Mirimanoff,
    there do not exist standard models of integers,

    Consider Boolos's theory ST with plural quantification.
    ⎛ set {} exists
    ⎜ set x∪{y} exists
    ⎜ set.extensionality
    ⎜ plurality ⦃z:P(z)⦄ exists
    ⎝ plurality.extensionality

    That can be augmented with
    a finite sequence of claims, each claim of which
    is true.or.not.first.false, and which
    ends with the claim that
    the standard integer.model exists, as a plurality.

    If it is true that
    our domain of discourse is a model of ST+PQ
    then it is true that
    our domain of discourse holds a standard integer.model.

    What is Mirimanoff's argument that
    it doesn't exist?

    that Russell has fooled you with a contradictory statement,
    and there are only fragments, if unbounded,
    and extensions, sublime.

    What statements has Russel made about ST+PQ?

    Mirimanoff's? Russell's Paradox.

    ST+PQ does not suffer from claiming
    that the set of all non.self.membered sets
    is self.membered or claiming it isn't.

    While I am at it,
    ZFC does not suffer from claiming
    that the set of all non.self.membered sets
    is self.membered or claiming it isn't,
    and
    ordinal.theory=Well.Order
    does not suffer from claiming
    that the set of all non.self.membered sets
    is self.membered or claiming it isn't.

    Is it possible that you (RF)
    have misunderstood Mirimanoff?

    That
    "If it is true that our domain of discourse
    is a model of ST+PQ then it is true that our
    domain of discourse holds a standard integer.model"
    is a pretty long axiom - why not just say
    "infinity", that's the usual approach.

    I don't say "infinity" is an axiom
    primarily because
    "infinity" is not an axiom of ST+PQ
    ST+PQ:
    ⎛ set {} exists
    ⎜ set x∪{y} exists
    ⎜ set.extensionality
    ⎜ plurality ⦃z:P(z)⦄ exists
    ⎝ plurality.extensionality

    "Infinity exists" ==
    "the minimal inductive plurality exists"
    is a theorem of those axioms.

    I said, in such a long.winded manner, that
    "infinity exists" is theorem of ST+PQ
    because,
    although I know that claim is well.justified,
    it sounded as though this person Mirimanoff
    has shown that I am mistaken about that.
    I wanted to put my justification out there
    for his argument to attack.

    No.
    The minimal inductive plurality is
    a standard model of the integers.

    Let's recall an example geometrically of what's
    so inductively and not so in the limit.

    Take a circle and draw a diameter, then bisect
    the diameter resulting diameters of common circles,
    all sharing a common diameter, vertical, say.

    Then, notice the length of the circle, is
    same, as the sum of the lengths of the half-diameter
    circles, their sum.

    So, repeat his dividing ad infinitum. In the limit,
    the length is that of the diameter, not the perimeter,
    while inductively, it's the diameter.

    Thusly, a clear example "not.first.false" being
    "ultimately.untrue".

    A finite sequence of claims, each claim of which
    is true.or.not.first.false is
    a finite sequence of claims, each claim of which
    is true.

    The reason that that's true is that
    THE SEQUENCE OF CLAIMS is finite.

    Whatever those CLAIMS refer to,
    none of those CLAIMS are first.false.
    (They're each not.first.false.)

    Since none of those CLAIMS are first.false,
    none of those CLAIMS are false.
    (That sequence is finite.)

    What those claims are ABOUT doesn't affect that.
    For example,
    being ABOUT an indefinite one of infinitely.many
    doesn't affect that.

    Discovering
    a finite sequence of claims, each claim of which
    is true.or.not.first.false
    in which there IS an untrue claim
    is akin to
    counting the eggs in a carton and

    7 is NOT between 6 and 8.

    It is so that
    that is what I argue, for, yes.

    I see at least two ways in which 'argue'
    might be used in our discussion here.

    'Argue.1' and 'argue.2' are distinguished by
    their order.in.discussion with respect to
    ⎛ a FINITE SEQUENCE OF CLAIMS, each claim of which
    ⎝ is true.or.not.first.false.

    ⎛ A FINITE SEQUENCE OF CLAIMS, each claim of which
    ⎜ is true.or.not.first.false is
    ⎜ a FINITE SEQUENCE OF CLAIMS, each claim of which
    ⎝ is true.

    I emphasize that
    it is THE CLAIMS in that sequence which
    are finitely.many, and
    it is EACH CLAIM in that sequence which
    either is true or is after a false claim.

    It is important enough that
    I would really like to hear from you,
    Ross Finlayson,
    either that you agree
    or what your objections are,
    so that I can address them.

    I already did you keep clipping it.

    Why don't you look back about the last three posts
    and see an example where an inductive argument FAILS
    and is nowhere finitely "not.first.false",
    that it yet FAILS.

    My first reaction was that this is not
    an inductive argument
    ⎛ A FINITE SEQUENCE OF CLAIMS, each claim of which
    ⎜ is true.or.not.first.false is
    ⎜ a FINITE SEQUENCE OF CLAIMS, each claim of which
    ⎝ is true.

    However, yes,
    my argument depends upon the well.ordering of CLAIMS,
    and that works out to being an inductive argument.

    ⎛ Assuming transfinite.induction is valid
    ⎜ in finite sequence P,
    ⎜ if,
    ⎜ for each claim,
    ⎜ its truth is implied by the truth of all prior claims,
    ⎜ then,
    ⎜ for each claim,
    ⎝ that claim is true.

    That is a transfinite.inductive argument.
    For finite sequence P of claims,
    ( ∀ᴾψ:(⊤ψ⇐∀ᴾξ≺ᴾψ:⊤ξ) ⇒ ∀ᴾφ:⊤φ

    So, it's a counterexample,
    and illustrates why what's not.first.false must
    also be not.ultimately.untrue to not FAIL.

    So, this is why I keep clipping your "counterexample".

    Your "counterexample" needs
    a finite sequence of claims which is NOT well.ordered.

    You say you have a counter.example.
    Congratulations. Your Fields Medal is in the mail.

    You say Mirimanoff and Finsler and Boffa support you.
    Do they have non.well.ordered finite sequences as well?
    Let's throw a party!

    Or, maybe, _kindly_ I should assume you misunderstand.

    Then about Russell's retro-thesis and

    Giving an ordinal assignment as "being", cardinals,
    results then there are those among CH and not CH,
    that would result contradictory models,
    and not even necessarily considering Cohen's forcing,
    and that he takes an ordinal out of a well-ordering,
    since you asked for example of out-of-order ordinals.

    Giving an assignment of reals

    Much shorter Ross Finlayson: "Yes"

    If you call me a liar for that summary,
    then it's "No" and I'll try again
    to explain the usefulness (NOT necessity)
    of not.first.false CLAIMS in
    finite.thus.well.ordered sequences.

    Of course I won't address your response.
    You're insisting on speaking a language

    How about a stoplight?

    In the temporal, and modal, and finite, thus fixed,
    there's a well-ordering of that.

    In the quasi-modal of whatever variety: there is not.

    Which I understand as "Yes, there are" and which
    you have not corrected.
    So, it is "Yes".

    To answer your question,
    that is misleading because
    what is meant by "finite" elsewhere
    (by me, by Paul Stäckel, by Wikipedia, ... )
    is well.ordered.in.both.directions.

    What I'm saying is that you can take back
    that "not.first.false" guarantees a claim
    for inference, when it doesn't.

    If one changes what words mean,
    then claims using them are different, and
    have different consequences.

    Is that the admission you want from me?
    Enjoy it in good health.

    "Broadly" speaking, ....

    Earlier you disputed that "not.first.false"
    and "not.ultimately.untrue" were any different.

    Now you don't.

    Earlier I tried to decipher
    what you mean by "not.ultimately.untrue"

    Now I don't.

    Now, I strongly suspect that
    you have stirred assumptions into "not.ultimately.untrue"
    about "not.first.false" and "finite sequences"
    that are not true,
    and that that's the reason I couldn't catch your meaning.

    Now, my focus is on
    finite (well.ordered.in.both.directions) sequences
    of true.or.not.first.false claims.

    Didn't he use not.ultimately.untrue

    Is that just an inversion?
    It seems to imply an ultimate or last
    instead of a first or least.
    Just like WM
    when he inverted the naturals
    to unit fractions.

    That sounds to me like a reasonable possibility.
    I don't myself right now see how to make it work.

    All I will ever have are guesses, though,
    unless Ross changes his tradition of
    not.answering questions like "What do you mean?"

    My guess -- and it is only a guess --
    is that not.ultimately.untrue is
    part of the innards of what I'll name
    The Discontinuous Function Paradox
    (note: not a paradox).

    In The Discontinuous Function Paradox,
    each of an infinite sequence is one way
    (let us say, each a true claim)
    _but the limit is something else_
    (a false claim)!!!
    _Obviously_ skullduggery is afoot!

    there exists a normal ordering that's a well-ordering
    and that all the orderings of the set are well-orderings.

    That's a great definition of finite and now it stands
    for itself in enduring mathematical definition in defense.

    Why is it you think that Stackel's definition of finite
    and "not Dedekind's definition of countably infinite"
    don't agree?

    No, I think that they agree,
    except possibly.not where countable.choice is possibly.wrong.
    because...
    ⎛ Necessary and sufficient conditions for finiteness

    ⎜ If the axiom of choice is also assumed
    ⎜ (the axiom of countable choice is sufficient),
    ⎜ then the following conditions are all equivalent:
    ⎜ 1. S is a finite set.
    ⎜ 2. (Richard Dedekind)
    ⎜ Every one-to-one function from S into itself is onto.
    ⎜ A set with this property is called Dedekind-finite.

    https://en.wikipedia.org/wiki/Finite_set

    I am satisfied that using the other definition
    which you mentioned isn't bait.and.switch.ing.

    ----
    Dedekind.finite with countable.choice is

    ⎝ ∃ch: ℕ→⋃Collection: ∀k∈ℕ:ch(k)∈S(k)

    Are there non.well.ordered finite sequences, Ross?

    If 'finite' is 'Dedekind.finite'
    and countable.choice is valid,
    then
    no finite sequence is non.well.ordered.

    ⎛⎛ Assume that
    ⎜⎜ P is a Dedekind.finite sequence of claims.

    A choice function is a function 'choice',

    All segments are infinite. Nothing can come "afterwards".
    Then the intersection is never empty.
    No finite intersection anyway.
    No intersection of infinite endsegments is finite.
    The infinite intersection is empty.

    Every infinite endsegments has an infinite intersection with all its predecessors.
    Itself, yes.

    If all endsegments are infinite, then this holds for all
    endsegments. They simply had not the chance to lose these numbers.
    It does. But it does not for the union of all of them - N itself,
    or E(0). It doesn't even have a predecessor.

    As what is left after not considering a finite initial segment in your
    new set and considering only the tail of the sequence.

    Not quite but roughly. The precise definitions are:
    Finite initial segment F(n) = {1, 2, 3, ..., n}.
    Endsegment E(n) = {n, n+1, n+2, ...}

    Almost all
    elements are considered in the new set, which means all endsegments are infinite.

    Every n that can be chosen has infinitely many successors. Every n that
    can be chosen therefore belongs to a collection that is finite but variable.

    Try to understand inclusion monotony. The sequence of endsegments
    decreases.

    In what manner are they decreasing?

    They are losing elements, one after the other:
    ∀k ∈ ℕ : E(k+1) = E(k) \ {k}
    But each endsegment has only one element less than its predecessor.

    When you filter out the FISON, the
    rest, the tail, as a set, stays the same size of aleph_zero.

    For all endsegments which are infinite and therefore have an infinite intersection.

    As long as it has not decreased below ℵo elements, the intersection
    has not decreased below ℵo elements.

    It doesn't decrease in size at all.

    Then also the size of the intersection does not decrease.
    Look: when endsegments can lose all elements without becoming empty,
    then also their intersection can lose all elements without becoming
    empty. What would make a difference?

    True. All endsegments are infinite. But they form a chain of inclusion,
    and there is no smallest set, because that chain is infinite.

    There is an infinite sequence of endsegments E(1), E(2), E(3), ...
    and an infinite sequence of their intersections
    E(1), E(1)∩E(2), E(1)∩E(2)∩E(3), ... .
    Both are identical - from the first endsegment on until every existing endsegment.

    The intersection of the "finite initial segment" of endsegments is
    ∩{E(1), E(2), ..., E(k)} = E(k)
    is a function which remains infinite for all infinite endsegments. If
    all endsegments remain infinite forever, then this function remains
    infinite forever.
    It does for all finite k.
    Of course. Only for finite k the endsegments are infinite.
    All natural k are finite.

    Then all endsegments are infinite like their intersections.

    Yes.
    Obviously and also provably.

    For each finite cardinal k

    No finite cardinal is |{n,n+1,n+2,...}|

    He says 'infinite endsegment' as if
    there were a choice,
    only to add confusion.

    I suspect that, sometime in the distant past,
    WM decided that 'infinite' meant
    'extremely, unusably large but not (what others mean by) infinite',
    which is an error.
    Famously, to err is human, and error, by itself,
    would never have ever aroused much interest.
    One corrects oneself,
    nods to the great mathematicians who have also erred,
    and moves on.

    However,
    WM decided to go another way,
    and he has spent the last 30(?) years
    trying to make reality conform to his error.

    Yes, 'infinite endsegment' adds confusion.
    And that pleases Mückenheim, I suspect.
    That confusion is the only impact his writings will ever make.

    But, in Mückenreich,
    first.infinite ω is countable.to and countable.past.
    There, ω merely serves as a marker between
    arbitrary (and changeable!) stretches of countable.to numbers.

    If 'infinite endsegment' isn't merely trolling
    (which a 30.year troll seems a bit extreme),
    I see "infinite endsegment" as one indicator that
    WM refuses to learn what 'infinite' means.

    No, you aren't.

    See: https://papers.ssrn.com/sol3/papers.cfm?abstract_id=5026625

    "Abstract: This work contains several arguments for the existence of
    dark numbers, i.e., numbers which cannot be manipulated as individuals
    but only collectively. Their existence depends on the premise of actual infinity. Whether actually infinite sets exist is unknown and cannot be
    proven; it can only be assumed as an axiom. But if actually infinite
    sets exist then dark elements are unavoidable. This concept helps to
    explain many paradoxes of set theory like Zeno's paradox or the paradox
    of the binary tree or the "completely scattered space" of the real axis."

    Nope, n here may be any element in IN.

    Right.

    Thank you Moebius. :^)

    So, if n = all_of_the_naturals, then

    No, /n/ has to be a natural number, i.e. an element in IN.

    Check the DEFINITION again:

    | Def.: F(n) =df {1, 2, 3, ..., n} (n e IN).

    "(n e IN)" means/states that only terms which refer to natural numbers
    are allowed here. [Thoug you may use other symbols instead of "n".]

    Hint: "all_of_the_naturals" does not denote a natural number.

    But the terms "1", "2", etc. ... do. :-P

    You may think of "(n e IN)" as some type information concerning the
    (defined) expression"F(n)". :-)

    { 1, 2, 3, ... }

    That's just a common symbol to denote IN (the set of natural numbers).

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

    Hm... Maybe your problem here is that NEITHER the symbol "{1, 2, 3, ...,
    n}" NOR the symbol "{1, 2, 3, ...}" have been (formally) defined.

    So let's do it now! (Better late than never.)

    | Def. {1, 2, 3, ..., n} =df {m e IN : m <= n} (n e IN)

    | Def. {1, 2, 3, ...} =df IN .

    Non sequitur. That which is true for finite sequences is not
    necessarily true for infinite sequences.
    As easily can be obtaied from the above it is necessarily true that up
    to every term and therefore also in the limit the sequences of
    endsegments and of intersections are identical. Every contrary opinion
    is matheology, outside of mathematics.
    What is the limit?

    If infinity is actual, then the FISONs {1, 2, 3, ..., n} have a limit,
    then the limit of the sequence of FISONs is ℕ. Then the limit of the complementary endsegments is the empty set.

    When WM writes:

    I think he might mean that n is somehow a largest natural number?

    Nope, he just means some n e IN.

    n = 3

    { 1, 2, 3 }

    Right?

    Right.
    Thank you Moebius. :^)

    So, i n = all_of_the_naturals, then

    You are in danger of falling into one of WM's traps here. Above, you
    had n = 3 and n = 5. 3 and 5 are naturals. Switching to n = all_of_the_naturals is something else. It's not wrong because there are
    models of the naturals in which they are all sets, but it's open to
    confusing interpretations and being unclear about definition is the key
    to WM's endless posts.

    { 1, 2, 3, ... }

    Aka, there is no largest natural number and they are not limited. Aka, no limit?

    The sequence of FISONs has a limit. Indeed that's one way to define N
    as the least upper bound of the sequence

    {1}, {1, 2}, {1, 2, 3}, ...

    although the all terms involved need to be carefully defined.

    Right?

    The numerical sequence 1, 2, 3, ... has no conventional numerical limit,
    but, again, if the symbols 1, 2, 3 etc stand for sets (as in, say, Von Neumann's model for the naturals) then the set sequence

    1, 2, 3, ...

    does have a set-theoretical limit: N.

    It's just that there are lots of kinds of limit, and a limit is not

    the set in question. R (the reals) can be defined as the "smallest" set
    closed under the taking of certain limits -- the limits of Cauchy
    sequences, the elements of which are simply rationals.

    Even if we don't consider FISONs, we can define a limit (technically a
    least upper bound) for the sequence 1, 2, 3, ... It won't be a natural
    number. We will have to expand our ideas of "number" and "size" to get
    the smallest "thing", larger than all naturals. This is how the study
    of infinite ordinals starts.

    @FromTheAfter: https://en.wikipedia.org/wiki/Set-theoretic_limit

    It's usually framed in terms of least upper bounds, so that might be why
    you are not recalling it.
    Ironically, there is a very common example of a "set theoretic limit"
    which is the point-wise limit of a sequence of functions. Since
    functions are just sets of pairs, these long-known limits are just the
    limits of sequences of sets. It's ironic because WM categorically
    denies that /any/ non-constant sequence of sets has a limit, yet the
    basic mathematics textbook he wrote includes the definition of the
    point-wise limit, as well as stating that functions are just sets of
    pairs. He includes examples of something he categorically denies!

    Same with the notions of /bijections/. Explained in his book but denied by
    WM these days.

    Ah, I had not seen him deny the notion of a bijection. Do you have a

    In every case of empty intersection of non-empty sets at least two such elements must exist. Important is not whether there are few or

    A linearly.ordered _finite_ set must be well.ordered.
    If all claims are true.or.not.first.false,
    there is no first false claim.
    Because well.ordered,
    if there is no first false,
    then there is no false,
    and all those not.first.false claims are justified.

    The natural numbers are not finitely.many.
    But that isn't a problem for this argument,
    because it isn't the finiteness of the _numbers_

    However, there is no largest natural number,
    Yes, there is no largest natural. Let's not loose sight of that.

    when I think of that I see no
    limit to the naturals. I must be missing something here? ;^o
    It's just that there are lots of kinds of limit, and a limit is not
    always in the set in question. Very often, limits take us outside of
    the set in question. R (the reals) can be defined as the "smallest" set
    closed under the taking of certain limits -- the limits of Cauchy
    sequences, the elements of which are simply rationals.

    So, the limit of the natural numbers is _outside_ of the set of all natural numbers?

    Yes.

    Even if we don't consider FISONs, we can define a limit (technically a
    least upper bound) for the sequence 1, 2, 3, ... It won't be a natural
    number. We will have to expand our ideas of "number" and "size" to get
    the smallest "thing", larger than all naturals. This is how the study
    of infinite ordinals starts.


    Okay... I need to ponder on that. Can I just, sort of, make up a "symbol"
    and say this is larger than any natural number, however it is definitely _not_ a natural number in and of itself?

    Yes, but everyone else already uses the symbol omega for it, so don't
    make up a new one.

    Damn. Still missing something here. Thanks for your patience... ;^o

    I don't think you are missing much in the big picture. The details are
    hairy but you can find them in a textbook on set theory.

    Thank you in advance for confirming or correcting
    my impression of what you mean
    (something you have not yet done),
    in furtherance of your
    forthcoming and forthright posting history.

    The thing is,
    'not.first.false' is not used to describe ordinals,
    in the way that 'yin.yang.ad.infinitum'
    is used to describe ordinals.

    'Not.first.false' is used to describe
    _claims about ordinals_ of which we are
      here only concerned with finitely.many claims.
    There is no 'ad infinitum' for 'not.first.false'.

    It is in part the absence of 'ad infinitum'
    which justifies claims such as [1] and [2]

    A linearly.ordered _finite_ set must be well.ordered.
    If all claims are true.or.not.first.false,
    there is no first false claim.
    Because well.ordered,
    if there is no first false,
    then there is no false,
    and all those not.first.false claims are justified.

    The natural numbers are not finitely.many.
    But that isn't a problem for this argument,
    because it isn't the finiteness of the _numbers_
    which it depends upon,
    but the finiteness of the claim.sequence.

    So, not.first.false,

    is an attribute of claims in
    a finite sequence of claims.

    So, not.first.false, is only
    after some pair-wise comprehension,
    because, there are ready example that
    (which you have not yet done)
    in "super-task comprehension",

    It is not a supertask to make
    finitely.many claims.

    It is not a supertask to verify
    the visibly not.first.false status of
    finitely.many.claims.

    Consider the possibility that
    what you think I am saying and
    what I actually am saying
    are not the same.

    No, the sets of algebraic numbers and of prime numbers have very

    The natural numbers are not finitely.many.
    But that isn't a problem for this argument,
    because it isn't the finiteness of the _numbers_
    which it depends upon,
    but the finiteness of the claim.sequence.

    About your posited point of detail, or question,
    about this yin-yang infinitum,
    which is non-inductive, and
    a neat also graphical example of the non-inductive,
    a counter-example to the naively inductive,
    as with regards to whether it's not so
    at some finite or not ultimately untrue,
    I'd aver that it introduces a notion of "arrival"
    at "the trans-finite case",

    Anyways your point stands that
    "not.first.false" is not necessarily
    "not.ultimately.untrue",
    and so does _not_ decide the outcome.

    Thank you for what seems to be
    a response to my request.

    You seem to have clarified that
    your use of
    'not.ultimately.untrue' and 'yin-yang ad infinitum'
    is utterly divorced from
    my use of
    'not.first.false'.

    Why do you say that? Your problem is you think that a complete infinite
    set is just finite, and thus your logic is just broken.

    Complete means it contains all of the values, and if those values are unbounded, then the set doesn't contain a bound for them, and thus not a
    "last" for them.

    This is part of the problem Aristotle was pointing out on trying to work
    with "Complete" sets that are infinite, that we, as finite beings, can't actually comprehend that unboundedness, as thus have misconceptions of
    what it "must" be like, which leads us to finding "inconsistencies".

    Those inconsistencies aren't in the sets themselves, but in our
    understanding of them.

    Aristotle realized that his logic system could not handle the logic of
    the complete unbounded set, but you apparently are stuck in that
    problem, and have let your mind be blown up by it.

    The sequence has no successors. Therefore all numbers including their successors are contained in the sequence.

    A sequence doesn't have successors, unless you are talking about a

    You are just stuck in your false notions of what you are talking about.

    A couple thousand years ago,
    the Pythagoreans developed a good argument
    that √2 is irrational.

    ⎛ The arithmetical case was made that,
    ⎜ for each rational expression of √2
    ⎜ that expression is not.first.√2

    ⎜ But that can only be true if
    ⎜ there _aren't any_ rational expressions of √2

    ⎜ So, there aren't any,

    Mathematicians,
    ever loath to let a good argument go to waste,
    took that and applied it (joyously, I imagine)
    in a host of other domains.

    Applied, for example, in the domain of claims.

    In the domain of claims,
    there are claims.
    There are claims about rational.numbers,
    irrational.numbers, sets, functions, classes, et al.

    An argument over the domain of claims
    makes claims about claims,
    claims about claims about rational numbers, et al.

    We narrow our focus to
    claims meeting certain conditions,
    that they are in a finite sequence of claims,
    each claim of which is true.or.not.first.false.

    What is NOT a condition on the claims is that
    the claims are about only finitely.many, or
    are independently verifiable, or,
    in some way, leave the infinite unconsidered.

    We narrow our focus, and then,
    for those claims,
    we know that none of them are false.

    We know it by an argument echoing
    a thousands.years.old argument.
    ⎛ There is no first (rational√2, false.claim),
    ⎝ thus, there is no (rational√2, false.claim).

    The intersection of all non.empty.end.segments

    The intersection of all non.empty.end.segments

    That is a wrong conclusion because

    This argument is wrong if

    Each finite.cardinal k is in

    There are at least

    ⎛ k is not common to all of those finitely.many end.segments.
    ⎜ k is not common to all end.segments.
    ⎝ k is not in the intersection of all end segments.

    Generalizing,

    Preface
    This book contains the collection of my writings on dark numbers most of
    which have been published already in lectures, at conferences, and here
    and there in the internet. Although I was a strong opponent of Cantor's
    actual infinity, an internet discussion in 2018 [1] has changed my mind
    in that without actual infinity the real axis would have gaps. That is
    my reason for accepting it and investigating its consequences.
    [W. Mückenheim: "Evidence for Dark Numbers", ELIVA Press, Chisinau 2024.

    Round up the usual suspects
    and label them 'definable'.

    ∀k ∈ ℕ : E(k+1) = E(k) \ {k} cannot come down to the empty set in definable numbers. No other way however is accessible.

    The intersection of all non.empty.end.segments

    And thus the limit of the subsets is not complete either, per your logic
    of a limit of constants is always that same constant. Thus, your trying
    to define the complete infinity just fails.

    But we can use *ANY* of the terms, as they all can individually be used individually.

    Your problem is the concept of a "last" one, or one with only a finite

    be infinite, as we would have a finite count of the memberhip.

    Same thing. Every finite number is "lost" in some segment.
    All segments are infinite.

    I really don't understand this connection. First, this also makes every

    Yes. It is E(1) having all natnumbers as its content.

    Take any natural number and run it through Cantor Pairing to get a

    But that is not really a problem.

    Thank you.
    That simplifies the expression of my point.

    Considering all non.empty end.segments of
    all finite.cardinals:

    Each finite.cardinal indexes
    one end.segment.

    Each end.segment is indexed by
    one finite.cardinal.

    Each finite cardinal is content of
    finitely.many end.segments,
    fewer than all
    more.than.any.finite end.segments.

    Each end.segment has as content
    more.than.finitely.many finite.cardinals,
    each finite.cardinal of which
    is in fewer.than.all end.segments.

    Elsewhere, considering one set, that's true.
    No element is both
    index(minimum) and content(non.minimum).

    However,
    here, we're considering all the end segments.
    Each content is index in a later set.
    Each non.zero index is content in an earlier set.

    "All at once" is

    Being.true is not an activity.

    A claim which is true of
    each of more.than.any.finite
    is true all.at.once of
    each of more.than.any.finite.

    All that happens in a sequence
    can be investigated at every desired step.

    At each step,
    investigating each up.to.that.step is not
    investigating each step.

    Our sets do not change.

    Each content is index in a later set.

    Only if all content is lost.

    The intersection of

    Eliva publishes two of my books. I had not to pay a cent.
    SSRN-Elsevier and De Gruyter published my books. I had not to pay a

    Which books, the same one?

    If you ever have something to publish that passes Eliva's terms of

    Same thing. Every finite number is "lost" in some segment.
    All segments are infinite.
    Two identical sequences have the same limit.
    As long as all endsegments are infinite so is their intersection.
    As long as you intersect only finitely many segments.

    Yes. It is E(1) having all natnumbers as its content.

    Do you even know how to take any natural number, create a unique pair

    I certainly don't know. Please tell me!
    Take any natural number and run it through Cantor Pairing to get a unique
    pair. From this pair alone we can also get back to the original number.

    Where can I find those natural numbers? And what EXACTLY do you mean by
    "run it through Cantor Pairing"? I and how does it _create_ pairs?

    Strange things are going on.

    I don't know if you objection is to CMT's rather unmathematical
    language, or if it is more philosophical than that, but in case it is
    just the former, CMT is probably referring to the classic bijection (and
    its inverse) between N and NxN given by (in Haskell)

    index_of (a, b) = (a + b)*(a + b + 1) `div` 2 + a

    pair n = (offset, sum - offset)
    where sum = floor ((sqrt(8 * fromIntegral n + 1) - 1)/2)
    offset = n - sum * (sum + 1) `div` 2

    Obviously this can be written in mathematical symbols, but Haskell is
    easier to post (because it's ASCII) and allows one to experiment with
    the mapping:

    ghci> map pair [0..10] [(0,0),(0,1),(1,0),(0,2),(1,1),(2,0),(0,3),(1,2),(2,1),(3,0),(0,4)]
    ghci> map index_of (map pair [0..10])
    [0,1,2,3,4,5,6,7,8,9,10]

    (The formulas are very similar if you prefer 1 to be the smallest
    natural.)

    And thus the limit of the subsets is not complete either, per your

    trying to define the complete infinity just fails.

    WM seems to think that "completed" means there simply must be a largest natural number? I can only guess here.

    He seems to think that Completed means all of them, but then he assumes
    that if you have "all" of a set, that set must have a last element.

    This comes from the fact that the only sets he can have are finite, and complete finite sets have a last element.

    He just doesn't get that a complete infinite set doesn't necessarily
    have a "last" element in it, because that concept is just unimaginable
    to his tiny brain.

    Well, that's fine. Wrt this subject its all about a Cantor pairing. Take

    E(n).
    That is not an infinite intersection.

    ⎜ If n is a finite.cardinal, then ⎜ n is.less.than n+1, and n+1 is
    finite.
    ⎝ n cannot be more.than.finitely.many.

    More than finitely many are *finitely many,
    *in
    unless they are actually infinitely many. Therefore they are not
    enough.
    Call it 'potential'.
    It is.
    None of that changes that each finite.cardinal is followed by a
    finite.cardinal,
    and leaves the set finite. But even for infinitely many n:
    ∀n ∈ ℕ: E(1)∩E(2)∩...∩E(n) = E(n).
    No empty intersection without an empty endsegment.
    That happens, as you know, only in the limit.

    Small wonder.
    More than finitely many endsegments require infinitely many
    indices,
    i.e., all indices. No natnumbers are remaining in the contents.
    ⎛ That's the intersection.
    And it is the empty endsegment.
    There is no empty segment.
    If all natnumbers have been lost, then nothing remains. If there are

    Yes, and then we don't need any more "contents".
    Then we have the empty endsegment.
    Only in the limit.

    The contents cannot disappear "in the limit". It has to be lost one
    by one if ∀k ∈ ℕ : E(k+1) = E(k) \ {k} is really true for all
    natnumbers.
    Same thing. Every finite number is "lost" in some segment.
    All segments are infinite.
    Two identical sequences have the same limit.
    As long as all endsegments are infinite so is their intersection.
    As long as you intersect only finitely many segments.
    ∀n ∈ ℕ: E(1)∩E(2)∩...∩E(n) = E(n)
    All n are infinitely many.
    That sentence only talks about a single n at a time, though,
    not about the infinite intersection.

    Yes. It is E(1) having all natnumbers as its content.
    And there is no empty segment.
    When you "don't need any more contents", there is the empty set.
    I.e. at no natural.

    You could hardly write something worse and more wrong that that.

    That is correct for definable natural numbers and even for almost all

    That all those n only produce finite intersections.

    This is not gibberish but mathematics:
    ∀n ∈ ℕ: E(1)∩E(2)∩...∩E(n) = E(n).
    Every counter argument has to violate this.
    False. For example, see above.

    Each finite.cardinal is not in common with more.than.finitely.many
    end.segments.
    Of course not. All non-empty endsegments belong to a finite set with an
    upper bound.
    There are definitely more than finitely many naturals and segments
    (none are empty).

    Each end.segment has, for each finite.cardinal,
    a subset larger than that cardinal.
    That is not true for the last dark endsegments. It changes at the dark
    finite cardinal ω/2.
    What changes to what? Why exactly there?

    The cardinality of the limit is the cardinality of the limit set.This

    Not the empty endsegment.
    ∀n ∈ ℕ: E(n) is non-empty. But not every E(n+1).

    You could hardly write something worse and more wrong that that.

    The very core property of N is that if n ∈ ℕ then n+1 ∈ ℕ.

    That is correct for definable natural numbers and even for almost all
    dark natural numbers.

    The very core property of analysis is that equal sequences have equal
    limits if they have limits at all.

    E(1)∩E(2)∩...∩E(n) = E(n)

    Lim E(1)∩E(2)∩...∩E(n) = {}
    Lim E(n) = {}

    The are equal.

    Not in a set theory where every endsegment is infinite.

    An empty limit endsegment requires finite predecessors because there is
    only one way to emptiness allowed, namely this one:
    ∀k ∈ ℕ : E(k+1) = E(k) \ {k}.

    the way 0^0 = 1 is simply a definition.

    But that is just showing the error in YOUR logic.

    The set of 0^x for all non-zero x is clearly 0, so since 0^0 is clearly
    the result of taking 0^x to the limit of x -> 0, that says, by your
    logic, that 0^0 must be 0.

    The ser of x^0, for all non-zero x is clearly 1, so since 0^0 is clearly
    the result of taking 1^x to the limit of x -> 1, that says, by your
    logic, that 0^0 must be 1.

    Thus 0^0 is both 0 and 1, but it must have just a value, so 0 must be 1.

    (We can make it a limit to infinity, by replacing x with 1/n)

    That is the error of assuming that just because a sequence apporaches a
    value as a limit (like your 1/10, 1/10, 1/10 ...) that this must be the
    "value" of the item at that limit.



    Just because you have a sequence, doesn't mean you can talk about the
    end infinite state at the "end" of the sequence.

    The end infinite state is a set.

    The end state is an infinite set, that doesn't have the same properties
    of the finite sets the form the sequence.


     you have two sequences that seem to go to the same infinte set at the
    end,

    Two sequences that are identical term by term cannot have different
    limits. 0^x and x^0 are different term by term.

    Which isn't the part I am talking of, it is that just because each step
    of a sequence has a value, doesn't mean the thing that is at that limit,
    has the same value.

    This ERROR seems to be a fondation of tour logic, a rule that tends to
    work in the finite realm, but fails at many infinities.

    Wrong. The sequences (E(1)∩E(2)∩...∩E(n)) and (E(n)) have precisely the same terms and therefore it is impossible that only one of them gets
    empty. If you prove that all endsegments are infinite, then you miss the

    That is exactly the problem of 0^x and x^0, both get you to the same

    A finite.cardinal is Original Cardinal.

    For both set sequences,

    Note, "inifinite" isn't a Natural Number, or a Real Number, so NO
    segement, specified by values, can have an "infinte endsegment".

    You seem to have a definitional problem.

    Of course, since you logic says that infinite sets act just like finite seqments, and thus no set is actually infinite, as well as that 0 is
    equal to 1 since they are both limits going to the same target, such a confusion is only natural.

    If a bijection with ℕ is possible, the sequence can be exhausted so that
    no natural numbers remains in an endsegment.
    For you: no, an infinite set cannot be exhausted in finite steps.

    It makes no sense not being able to „apply” numbers. Clearly Cantor

    He claims it. That means no numbers remain unpaired in endsegments.
    As you haven’t disproven.

    The sequence IS continuous. It’s just that you misconceive of the limit
    as reachable.
    Cantor does. If the limit is not reachable, then complete bijections
    cannot be established.
    The limit is only reachable… at infinity.

    "If we think the numbers p/q in such an order [...] then every number
    p/q comes at an absolutely fixed position of a simple infinite sequence"
    [E. Zermelo: "Georg Cantor – Gesammelte Abhandlungen mathematischen und philosophischen Inhalts", Springer, Berlin (1932) p. 126]
    "The infinite sequence thus defined has the peculiar property to contain
    the positive rational numbers completely, and each of them only once at
    a determined place." [G. Cantor, letter to R. Lipschitz (19 Nov 1883)]

    If you accept these claims, then no number must remain in an endsegment.
    True: no number is in all endsegments.
    False: there is a segment with no numbers.

    But a segment that is infinite in length is, by definiton, missing at
    least on end.

    That end isn't "infinite", it doesn't have an end in that direction.

    You might notionally call that end "infinity", but that isn't its end,
    and it would be an "open" end for that segment (as infinity isn't a
    finite number, so isn't an element of any segment of finite numbers).

    So, all you are doing is showng that you don't understand what you are
    talking about, and just making up shit to try to sound like you do.

    This just show why your logic has blown itself up into smithereens from
    its contradictions, since you can't follow the definitions of real math.


    So, which bijection from Cantor are you talking about? Of are you
    working on a straw man that Cantor never talked about?

    For you: no, an infinite set cannot be exhausted in finite steps.

    There are infinitely many steps. Every element of an endsegment is a

    If you accept these claims, then no number must remain in an endsegment.
    True: no number is in all endsegments.
    False: there is a segment with no numbers.

    Numbers within endsegments cannot appear as indices (except one).

    Impossible, since k and k+1 etcetera are natural numbers.

    Then Cantor cannot get them out of the endsegments either. He claims to
    use all natural numbers as indices in mappings. For instance the famous Cantor-list would not prove anything uncountable iunless all natural
    numbers with no exception were indices of the lines.

    And there must be a continuous staircase from E(k) to the empty set.

    A limit set or element does not have to be completely within a set or interval.

    But all numbers remaining in endsegments are not usable for mappings.

    But a segment that is infinite in length is, by definiton, missing at

    That means that the premise "if Cantor can apply all natural numbers as
    indices for his bijections" is false.
    So, which bijection from Cantor are you talking about? Of are you
    working on a straw man that Cantor never talked about?

    There are many. The mapping from natumbers to the rationals, for
    instance, needs all natural numbers. That means all must leave the
    endsegments. Another example is Cantor's list "proving" uncountable
    sets. If not every natural number has left the endsegment and is applied
    as an index of a line of the list, the list is useless.

    But if every natural number has left the endsegments, then the
    intersection of all endsegments is empty. Then the infinite sequence of endegments has a last term (and many finite predecessors, because of
    ∀k ∈ ℕ : ∩{E(1), E(2), ..., E(k+1)} = ∩{E(1), E(2), ..., E(k)} \ {k}).

    There are many. The mapping from natumbers to the rationals, for
    instance, needs all natural numbers. That means all must leave the endsegments. Another example is Cantor's list "proving" uncountable
    sets. If not every natural number has left the endsegment and is applied

    Don't say what not is. Explain your vision of the problem:
    If ℕ is a set, i.e. if it is complete such that all numbers can be used
    for indexing sequences or in other mappings, then it can also be
    exhausted such that no element remains. Then the set of what remains
    unused, i.e., of intersections of endsegments

    (1) E(1), E(1)∩E(2), E(1)∩E(2)∩E(3), ...

    loses all content. Then, by the law

    (2) ∀k ∈ ℕ : ∩{E(1), E(2), ..., E(k+1)} = ∩{E(1), E(2), ..., E(k)} \ {k}

    the content must become finite.

    Which means
    ⎛ if k is finite
    ⎝ then k+1 is finite

    This contradicts the fact that nothing remains but every element can go

    Each end.segment ⟦k,ω⦆ of ⟦0,ω⦆ contains,

    a subset ⟦k,k+j⟧ holding more.than.j.many.

    Then the intersection is never empty (or only for definable finite

    No. It is literally „without an end”,

    The end is reached when all content has gone because more cannot go.
    Then the intersection of endsegments which was not empty before has
    become empty. This cannot happen other than by the law
    ∀k ∈ ℕ : ∩{E(1), E(2), ..., E(k+1)} = ∩{E(1), E(2), ..., E(k)} \ {k}

    and yet can be „completed”, if
    only you were able to conceive of infinity.

    That is not a property of infinity but illogical nonsense.

    Yes, in the limit. There is no natural k such that E(k) is empty.

    The sequence of intersections loses all content but only according to
    the rule
    ∀k ∈ ℕ : ∩{E(1), E(2), ..., E(k+1)} = ∩{E(1), E(2), ..., E(k)} \ {k}.

    And there must be a continuous staircase from E(k) to the empty set.
    This is where you are mistaken.

    It is the definition of endegments. If endsegments exist, then they
    follow this rule.

    How do you get from naturals to
    finite dark numbers anyway?

    That is the same as without dark numbers. The visible numbers are
    potentially infinite.

    So? That isn't what Cantor was talking about in his pairings
    It is precisely this.
    No, Cantors pairing is between two SETS, not a set and its subset.
    Yes, we can call the subset a set, since it is, but then when we look
    at it for the pairing, we need to be looking at its emancipated
    version, not the version tied into the original set.
    Both is the same. In emancipated version it is not as obvious as in
    the subset version.
    Nope, when the subset is considered as its own independent set, the
    operation you want to do isn't part of its operations.
    The subset is considered as its own independent set D = {10n | n ∈ ℕ}
    and then it is attached to the set ℕ = {1, 2, 3, ...}. R´That does not change the subset.
    It changes the set from D to N and thus the function.

    It doesn't exist in the defined number space, just like sqrt(-1) doesn't

    Yes, there may be a super-trans-finite numbering system that defines it,
    but it isn't in the Number Set that you claim to be talking about.

    There is not series of successions from 0 that will get you to ω-1.

    There isn't even a series of successions from 0 that will get you to ω,
    as ω is the first ordinal of the new type.

    Unless you have changed whatᵂᴹ you (WM) mean,
    an actuallyᵂᴹ infinite set is smaller.than
    a fuller.by.one set, but
    it contains a potentiallyᵂᴹ infinite subset, meaning
    a subset not.smaller.than a fuller.by.one set.

    Unless you have changed whatᵂᴹ you (WM) mean,
    to completeᵂᴹ a potentiallyᵂᴹ infinite set means
    to insert an epilogue (presumably darkᵂᴹ) so that
    set+epilogue is actuallyᵂᴹ infinite.

    Your (earlier, possibly.current) explanation of how
    a smaller.than.fuller.by.one set can contain
    a not.smaller.than.fuller.by.one subset
    is that
    the (undeniably one.to.one) identity map x ↦ x
    doesn't work somehowᵂᴹ in the darkᵂᴹ appendix.

    Georg Cantor and matheologians do not use
    sets in which x ↦ x doesn't work somehowᵂᴹ.

    They (we) use sets which do not change.
    I include among our sets
    sets which you (WM) say change, of which
    you often also say that
    they're only potentiallyᵂᴹ infinite.
    But, no, all of our sets do not change.

    Some of our (unchanging) sets are
    not.smaller.than a fuller.by.one set.

    Explain your vision of the problem:

    Some of our (unchanging) sets are

    That's not the problem.
    The problem is that you (WM) don't accept that.

    In order to avoid accepting that,
    you (WM) try various work.arounds, for example,
    by declaring that
    x ↦ x doesn't work when that'd be inconvenient.

    My attempts to resolve your problem (not our problem)

    That is the collection of numbers known as the Natural Numbers, so I

    All you are doing is showing that you don't understand that an infinite
    set doesn't have a "last" member, and is catagorically bigger than any
    finite set.

    Thus, all you have done is shown that your logic is just totally
    exploded leaving a "dark hole" behind from its nuclear explosion into smithereens from the contradictions you make it generate.

    Sorry, but that is the truth, which seems to be beyond your ability to understand.

    Therefore people were unaware of its failure.

    But your logic can't deal with ALL Fisons.

    Note, the mapping isn't in your [1, n] but in N.

    Your logic that if it holds for all FISONs, it holds for N, is what
    shows that 0 == 1, so we see that logic is broken when it is applied to
    truely infinite things.

    Why does your FISON look like a real interval?
    Originally I had used unit intervals [n, n+1] of real intervals (0,

    Many members can be subtracted individually but infinitely many

    An unbounded number can be subtracted individually.

    #⟦0,j⦆ = #⟦0,i⦆ + #⟦i,j⦆

    And so on, and so on.

    Our foundation of sheep and pebbles considers
    that which is smaller.than.Bobbed: the finite.

    We don't need to always restrict our considerations
    to sheep and pebbles, to the finite.

    The set {⟦0,i⦆:smaller.than.Bobbed}
    cannot itself be smaller.than.Bobbed.

    ⎛ Each ⟦0,j⦆ ∈ {⟦0,i⦆:smaller.than.Bobbed}
    ⎜ is smaller than {⟦0,i⦆:smaller.than.Bobbed}

    ℕ = ⋃{⟦0,i⦆:smaller.than.Bobbed} = {0,1,2,3...}

    {⟦0,i⦆:smaller.than.Bobbed} is not.smaller.than.Bobbed

    #ℕ = #{⟦0,i⦆:smaller.than.Bobbed}

    ℕ is not.smaller.than.Bobbed

    However,
    ∀j ∈ ℕ:
    ⟦0,j⦆ ∈ {⟦0,i⦆:smaller.than.Bobbed}
    and ⟦0,j⦆ is smaller.than.Bobbed.

    If I understand you (WM), you have been arguing that,
    because ∀j ∈ ℕ: ⟦0,j⦆ is smaller.than.Bobbed,
    ℕ must be smaller.than.Bobbed, and thus
    there must be darkᵂᴹ numbers to account for the discrepancy.

    Explain your vision of the problem:

    (1)
    When we consider all finite sequences ⟦0,j⦆,
    meaning sequences smaller.than.Bobbed,
    what we should consider are
    the finite initial segments of ⋃{⟦0,i⦆:smaller.than.Bobbed}
    That is, ℕ should be ⋃{⟦0,i⦆:smaller.than.Bobbed}

    Inserting an epilogue makes our considerations about
    things different from sequences smaller.than.Bobbed.

    (1')
    Our considerations indicate that,
    unlike the finite initial segments of ℕ
    ℕ is not.smaller.than.Bobbed.

    That isn't a problem to be solved.
    It is a possibly.interesting fact we have uncovered.

    (2)
    Inserting an epilogue does not perform as advertised.

    ℕ is not.smaller.than.Bobbed.
    For any epilogue 𝔻, ∀d ∈ 𝔻: g(d) = d
    ℕ∪𝔻 is not.smaller.than.Bobbed.

    If we followed your directions,
    we'd give up considering the smaller.than.Bobbed sequences
    for no benefit,
    not even a benefit we didn't much want,
    such as the elimination of the not.smaller.than.Bobbed.

    Your FISONS are all finite sets, so none of them are N.

    The set is different then each of its members, the whole is more than

    How is your f(n) an "infinite sequence, since n is a finite number in
    each instance.

    NONE of your f(n) contains *ALL* natural numbers, since no "n" is the
    highest natural number, since suc a number doesn't exist,

    Your problem is you just don't understand what "infinity" is, and seem
    to think it is just some unimaginably bit but finite number, which is
    just wrong.

    You deny the limit.

    When dealing with Cantor's mappings between infinite sets, it is argued
    usually that these mappings require a "limit" to be completed or that
    they cannot be completed. Such arguing has to be rejected flatly. For
    this reason some of Cantor's statements are quoted below.

    "If we think the numbers p/q in such an order [...] then every number
    p/q comes at an absolutely fixed position of a simple infinite sequence"
    [E. Zermelo: "Georg Cantor – Gesammelte Abhandlungen mathematischen und philosophischen Inhalts", Springer, Berlin (1932) p. 126]

    "thus we get the epitome (ω) of all real algebraic numbers [...] and
    with respect to this order we can talk about the th algebraic number
    where not a single one of this epitome () has been forgotten." [E.
    Zermelo: "Georg Cantor – Gesammelte Abhandlungen mathematischen und philosophischen Inhalts", Springer, Berlin (1932) p. 116]

    "such that every element of the set stands at a definite position of
    this sequence" [E. Zermelo: "Georg Cantor – Gesammelte Abhandlungen mathematischen und philosophischen Inhalts", Springer, Berlin (1932) p. 152]

    The clarity of these expressions is noteworthy: all and every,
    completely, at an absolutely fixed position, th number, where not a
    single one has been forgotten.

    How is your f(n) an "infinite sequence, since n is a finite number in

    How is Cantor's sequence infinite since every positive rational number
    is finite?

    NONE of your f(n) contains *ALL* natural numbers, since no "n" is the
    highest natural number,

    None of Cantor's terms q_n contains all rational numbers, sice no n is
    the highest natural number.

    Your problem is you just don't understand what "infinity" is

    Your problem is that you believe to understand it.

    ∩{E(1), E(2), ..., E(k+1)} =
    ∩{E(1), E(2), ..., E(k)} \ {k},
    i.e. to lose one number per term of
    the function
    f(k) = ∩{E(1), E(2), ..., E(k)}.

    f(k) = E(k) = ⟦k,ℵ₀⦆

    Yes,
    after infinitely.many one.number.losses,
    infinitely.many numbers are lost.

    That means all numbers are lost by loss of one number per term. That
    implies finite endsegments.

    However,
    each number is not.after infinitely.many numbers,
    each loss is not.after infinitely.many losses.

    As long as any natural number remains, the sequence of lost numbers is
    finite (ended by the remaining number).

    The empty term

    There is no darkᵂᴹ or visibleᵂᴹ empty term.

    Finite intersections of endsegments preceding the empty intersection of
    all endsegments are dark.

    ⎛ Assume otherwise.

    For my argument I don't need empty endsegments.

    The empty term
    has lost all natnumbers one by one.

    One.by.one and (darkᵂᴹ or visibleᵂᴹ) endlessly.

    If Cantor uses all indices for his bijections the intersection of all endsegments must be empty.

    How is Cantor's sequence infinite since every positive rational number

    Because there is an infinite number of numbers.


    NONE of your f(n) contains *ALL* natural numbers, since no "n" is the
    highest natural number,

    None of Cantor's terms q_n contains all rational numbers, sice no n is
    the highest natural number.

    ??? Where does Cantor assume there is a highest n?

    He builds an infinite sequence that pairs a netual number to every
    rational number .Actualy to every number pair, so every rational number
    get paired to many natural number showing that the rationals can not be
    bigger than the Naturals. But since every Natural Number is a rational,
    there can't be more Natural Nubmers than Rational Numbers, so we can
    show they must be the same size.


    Your problem is you just don't understand what "infinity" is

    Your problem is that you believe to understand it.

    In other words you ADMIT you don't understand what you are talking about?

    Wrong.

    So, you admit to just being a liar, as you keep on talking about the
    Natural Numbers.

    And you don't use ALL natural numbers, as you logic doesn't allow you to
    do the needed infiite operations to use ALL, only ANY,

    No FISION uses ALL the Natural Numbers, so your claim is just shown to
    be stupid (like you).

    Your problem is you need to intersect *ALL* the sets, and that is an
    infinite amount, but your logic only allow the processing of a finite
    number of set.

    Since and infinte number is bigger than a finite number, your problem
    comes down to the fact that you tools just can't do the job.

    That is shown by the fact that if you try to build the set of Natural
    Numbers one at a time by adding each number individually, you never
    reach the end, so your tools could never have the set of the Natural
    Numbers to work with in the first place.

    All you are doing is proving that you brain is just broken and has
    exploded into a dark hole by the contradictions you have inflected upon
    it by using it for things it is just incapable of handling.

    They do not wish to recognize that their theory is self-contradictory.
    But perhaps students would be interested. I tell them the following story.

    The function E(n) decreases from infinity to zero because in set theory
    ℕ \ {1, 2, 3, ...} = { } is an accepted formula.

    The set ℕ can get empty by subtracting its elements. Either this is
    possible one by one, then finite endsegments do exist, or it is only
    possible be removing (after the first elements one by one) the remaining elements collectively. This shows the existence of numbers which can be
    handled collectively only.

    How should we call them?

    Another approach is to call the empty set the limit of the sequence
    E(n). But note that a limit is a set between which and all terms of the sequence nothing fits. Therefore the limit empty set causes sets with
    few elements only.

    No, you do what you THINK Cantor did, but you don't understand what he

    This shows by the fact that you find the need to alter what he does to something different that you do understand, that you think is the same,

    Except that you don't understand that infinitiy minus 1 is still
    infinity, and thus did not "decrease".

    All you have shown is that your logic is built of FALSE ASSUMPTIONS
    because it uses rules that only hold for FINITE quantities, because you
    thing everything is just like the finite, and thus your logic blows up
    and lies when it needs to handle the infinite.

    One by one. Every endsegment transforms a natural number from content

    ∀k ∈ ℕ : ∩{E(0), E(1), E(2), ..., E(k+1)} = ∩{E(0), E(1), E(2), ...,

    Except that you don't understand that infinitiy minus 1 is still
    infinity, and thus did not "decrease".

    The sets E(n) decrease. If the sequence (E(n)) could not get empty one
    by one then Cantor could not set up an infinite sequence using all

    The LAST one, that completes the set.

    Your logic insists on that, but you don't use it.

    The fact that after any finite number of removals, there are still
    elements does not mean that when you remove *ALL* the elements there
    will still be some left.

    Your logic just is using the wrong logic of the conditional you are
    claiming to be using, and thus the results do not hold.

    Since your logic CAN'T complete, doing infinite work individually, it
    can't talk about the results when it does complete.

    We do not know a finite initial segment (FISON) for any dark number. If

    known for numbers which will never become visible: ω-1, ω/2, ω/10.

    This fact shows that "all" cannot be removed individually. They can only
    be removed collectively. Proof of dark numbers.

    No, that does NOT prove what you claim.

    The problem is that we can not "see" all the numbers at once, not

    certain facts about being.finite.
    However,
    there are some who disagree with those facts.
    That's what has my attention, at the moment.

    My thought is that

    No, doing an INFIITE union (which a union of all FISONs would be) can
    result in something different in type then the union of a finite number
    of FISONs.

    Just like the combining of ALL natural numbers gives us an infinite set,
    while ony combining a finite number of natural numbers gives us a finite
    set.

    You logic just can't handle infinite operations, and thus can't actually
    have the set of Natural Numbers as an element of it,

    No. There are infinitely many, so the union must be infinite too.

    The problem is the upper limit for the ratio of a FINITE set of fusions

    Sure, if your threshold is n, then the fision from 1 to n+1 is bigger
    than that. and from there you can get to n+2, then n+3, and can start to understand what happens as you get to infinity.

    Of course, to do that, you need to abandon the concept that you are only working with SOME of the set, and not ALL of it, and thus there isn't a
    "last" element, as the set is infinite.

    Which shows that it isn't "a number", but one of an infinite set, and
    the set your are talking about is always a finite subset, and thus never
    the actual full set Natural Numbers or FISONs and thus your logic can't

    Sorry, you are just proving that you are mentally incapable of handling

    No, your threshold is just an admission that you are only going to look

    All you have proved is that any finite set has a maximum value, while
    the INFINITE set of Natural Numbers (or FISONs) do not, and thus your

    No, the problem is you always stop before you get to the end of unioning
    EVERY FISON, as you always have a stopping point.

    The problem is infinity doesn't have an end, so you can't get to it by individual finite steps that can't be processed without end. THus, your
    "logic" jsut fails to have the needed tools to handle, or even create, a infinite set.

    Your logic doesn't HAVE the full set of the Natural Numbers, or EVERY

    The finite numbers are finite, and that is it.

    FISONs do not grow by unioning them. All FISONs and their unions
    stay below 1 % of ℕ.

    Proof: Every FISON that is multiplied by 100 remains a FISON that
    can be multiplied by 100 without changing this property.

    If ℕ is an actually infinite set then it is not made by FISONs.

    That is what I have been telling you for a long time.

    But there is no Natural Number that isn't in a FISON, which is NOT
    what you have been saying.

    You don't seem to understand the difference between a set and its
    members.

    He has in the past explicitly stated such. Something like 'a set is
    nothing more than its elements' -- I don't think he has changed his tune.

    Which is just a categorical error, showing that he doesn't know what he
    is talking about.

    Yes, SOME of the properties of the set come from properties of its
    members, but just because we can add together two numbers, doesn't mean
    we can arbitrarily add together two sets of numbers, or even know what
    that would mean to do.

    But then you think that a finite combination of these finite sets could possible by an infinite set, or even the results of combining *ALL* of
    the members of the infinite set of FISONs. Even though each one is
    finite, there is an infinite number of them, so words like "Every" or
    "All" require a logic that can actually handle that infinity, which
    yours doesn't, as you can deal with all the members of an infinite set individually with a finite process.


    If ℕ is an actually infinite set then it is not made by FISONs.

    That is what I have been telling you for a long time.

    But there is no Natural Number that isn't in a FISON, which is NOT

    You cannot find a natural number that isn't in a FISON. But there must
    be more because FISONs cover less than 1 % of ℕ.

    Right, but there are an INFINTE number of FISONs, just like there are an INFINITE number of natural numbers, so any system that can only handle a
    finite number of operations can't be expected to fully handle the set of
    FISONs or Natural Numbers.


    The problem is your logic can't have "Every" FISON, because "every
    FISON" is an infinite set of them,

    Every mathematician knows that every FISON is finite as its name says
    and covers at most 1 % of ℕ.

    But, when you actually take into accout EVERY FISON, the full INFINITE
    set, you get to them all. Of course, your problem is that you logic
    system can't actually handle EVERY FISON, just ANY FISON, and thus can't determine the property of the union of EVERY FISON.

    You just don't understand the nature of the universal qualifier as
    applied to truely infinite sets.

    Would you then believe that not all swaps had been swapped?

    Bob comes to rest within the dark part.

    Then not all swaps are swapped

    For people not blinded by set theory it is clear that the X cannot cover
    the whole matrix. Therefore the limit in
    XOOO... XXOO... XXOO... XXXO... ... XXXX...
    XOOO... OOOO... XOOO... XOOO... ... XXXX...
    XOOO... XOOO... OOOO... OOOO... ... XXXX...
    XOOO... XOOO... XOOO... OOOO... ... XXXX... ...............................................
    can only represent a small part of the matrix.

    Every exchange happens between two sites.

    Yes.
    Always between two visibleᵂᴹ sites.
    And no single swap disappears Bob.

    In no single swap *that is observed*!

    Infinitely.many is different from finitely.many.
    For each finitely.many, there are more.

    But the first column is exactly as long as the first row.

    After all swaps,
    ⎛ Bob has never swapped into any darkᵂᴹ room,
    ⎝ Bob has swapped out of any visibleᵂᴹ room,
    Bob is nowhere.

    But Bob is never out of the matrix
    because
    there is no exchange at all between outside and inside.

    Yes, Bob never exits the matrix.
    However, after all swaps, Bob isn't in the matrix.
    Therefore, infinite is different.

    No, set theorists have been blinded.

    Again, you don't understand that the union of EVERY FISON is a infinite operation, since there are an infinite number of FISONs, even if each

    You just don't understand that infinite is not finite, and you logic

    because we can see a description of all FISONs,

    From this description we know that every FISON has

    A description of FISONs can be grasped.

    No, becuase "all which stay below a certain threshol" is not EVERY

    There isn't one, but anytime you CHOSE what you limit is, I can go past it.

    So? You are just showing that individual finite sets are finite and not infiniite.

    When you combine *ALL* FISONs, you get a property that none of them have individually, and that is the infinite nature, which only comes from combinining an INFINITE number of FISONs, which your logic can't do.

    Your problem is you can't imagine what an infinite set actually is,

    There are infinitely many FISONs. What in the heck do you mean by using
    the word, "potentially"? It's as if you don't think infinity exists?

    "We introduce numbers for counting. This does not at all imply the
    infinity of numbers. For, in what way should we ever arrive at
    infinitely-many countable things? [...] In philosophical terminology we
    say that the infinite of the number sequence is only potential, i.e.,
    existing only as a possibility." [P. Lorenzen: "Das Aktual-Unendliche in
    der Mathematik", Philosophia naturalis 4 (1957) p. 4f]

    "Until then, no one envisioned the possibility that infinities come in different sizes, and moreover, mathematicians had no use for 'actual
    infinity'. The arguments using infinity, including the Differential
    Calculus of Newton and Leibniz, do not require the use of infinite sets.
    [...] Cantor observed that many infinite sets of numbers are countable:
    the set of all integers, the set of all rational numbers, and also the
    set of all algebraic numbers. Then he gave his ingenious diagonal
    argument that proves, by contradiction, that the set of all real numbers
    is not countable. A consequence of this is that there exists a multitude
    of transcendental numbers, even though the proof, by contradiction, does
    not produce a single specific example." [T. Jech: "Set theory", Stanford Encyclopedia of Philosophy (2002)]

    "Numerals constitute a potential infinity. Given any numeral, we can
    construct a new numeral by prefixing it with S. Now imagine this
    potential infinity to be completed. Imagine the inexhaustible process of constructing numerals somehow to have been finished, and call the result
    the set of all numbers, denoted by . Thus  is thought to be an actual infinity or a completed infinity. This is curious terminology, since the etymology of 'infinite' is 'not finished'." [E. Nelson: "Hilbert's
    mistake" (2007) p. 3]

    According to (Gödel's) Platonism, objects of mathematics have the same
    status of reality as physical objects. "Views to the effect that
    Platonism is correct but only for certain relatively 'concrete'
    mathematical 'objects'. Other mathematical 'objects' are man made, and
    are not part of an external reality. Under such a view, what is to be
    made of the part of mathematics that lies outside the scope of
    Platonism? An obvious response is to reject it as utterly meaningless."
    [H.M. Friedman: "Philosophical problems in logic" (2002) p. 9]

    "A potential infinity is a quantity which is finite but indefinitely
    large. For instance, when we enumerate the natural numbers as 0, 1, 2,
    ..., n, n+1, ..., the enumeration is finite at any point in time, but it
    grows indefinitely and without bound. [...] An actual infinity is a
    completed infinite totality. Examples: , , C[0, 1], L2[0, 1], etc.
    Other examples: gods, devils, etc." [S.G. Simpson: "Potential versus
    actual infinity: Insights from reverse mathematics" (2015)]

    "Potential infinity refers to a procedure that gets closer and closer
    to, but never quite reaches, an infinite end. For instance, the sequence
    of numbers 1, 2, 3, 4, ... gets higher and higher, but it has no end; it
    never gets to infinity. Infinity is just an indication of a direction –
    it's 'somewhere off in the distance'. Chasing this kind of infinity is
    like chasing a rainbow or trying to sail to the edge of the world – you
    may think you see it in the distance, but when you get to where you
    thought it was, you see it is still further away. Geometrically, imagine
    an infinitely long straight line; then 'infinity' is off at the 'end' of
    the line. Analogous procedures are given by limits in calculus, whether
    they use infinity or not. For example, limx0(sinx)/x = 1. This means
    that when we choose values of x that are closer and closer to zero, but
    never quite equal to zero, then (sinx)/x gets closer and closer to one."
    [E. Schechter: "Potential versus completed infinity: Its history and controversy" (5 Dec 2009)]

    The sequence of increasing circumferences (or diameters, or areas) of
    circles is potentially infinite because the circumference of a circle
    can become arbitrarily long, but it cannot be actually infinite because
    then it would not belong to a circle. An infinite "circumference" would
    have curvature zero, i.e., no curvature, and it could not be
    distinguished what is the inner side and what is the outer side of the
    circle.

    The length of periods of decimal representations of rational numbers is potentially infinite. The length is always finite although it has no
    upper bound. The decimal representation is equal to a geometric series,
    like 0.abcabcabc... = abc(10-3 + 10-6 + 10-9 + ...) which converges to
    the limit . A never repeating decimal sequence has an irrational limit.

    An interval of natural numbers without any prime number is called a
    prime gap. The sequence of prime gaps assumes arbitrarily large
    intervals but it cannot become actually infinite. None of the numbers n!
    + 2, n! + 3, n! + 4, ..., n! + n can be prime because n! = 123... n contains 2, 3, ..., n as factors already. Therefore the set of gaps has
    no upper bound. It is potentially infinite. It is not actually infinite however, because there does not exist a gap with no closing prime number because there is no last prime number.

    Finally, the most familiar example is this: The (magnitudes of) natural
    numbers are potentially infinite because, although there is no upper
    bound, there is no infinite (magnitude of a) natural number.

    Your problem is your naive mathematics can't define the terms you are

    ℕ is the set of each and only finite.ordinals.

    A finite.ordinal is larger.by.one than emptier.by.one
    unless it is 0 = ⦃⦄
    ⎛ finite k ⇔

    By definition of ℕ
    for each set A larger.by.one than emptier.by.one,
    (for each finite set)
    there is an ordinal k in ℕ, ⟦0,k⦆ the same size as A
    ⎛ #A > #(A\{a}) ⇒
    ⎝ ∃k ∈ ℕ: #⟦0,k⦆ = #A

    There isn't an ordinal #ℕ in ℕ of the same size as ℕ
    Set ℕ is not larger.by.one.than.emptier.by.one.
    ⎛ ¬∃k ∈ ℕ: #⟦0,k⦆ = #ℕ ⇒
    ⎝ ¬(#ℕ > #(ℕ\{0}))

    For each set Y the same size as ℕ
    There isn't an ordinal #Y in ℕ of the same size as Y
    Y is not larger.by.one.than.emptier.by.one
    ⎛ ¬∃k ∈ ℕ: #⟦0,k⦆ = #Y ⇒
    ⎝ ¬(#Y > #(Y\{y}))

    |ℕ| := ℵ₀ = |ℕ\{0}| = |ℕ\{0,1}| = ... =
    |ℕ\{0,1,...,n}| = ...

    The sequence of end.segments of ℕ
    grows emptier.one.by.one but
    it doesn't grow smaller.one.by.one.

    ∀n ∈ ℕ_def: |ℕ \ {1, 2, 3, ..., n}| = ℵo

    ℕ is the set of each and only finite.ordinals.

    Each finite.ordinal is not weird.
    Even an absurdly.large one like Avogadroᴬᵛᵒᵍᵃᵈʳᵒ
    is not weird.

    However,
    ℕ is weird.

    Declaring that ℕ is not weird, but
    like an absurdly.large finite.ordinal,
    does not make ℕ
    like an absurdly.large finite.ordinal,
    because
    ℕ is the set of each and only finite.ordinals,
    which is not any finite.ordinal,
    not even an absurdly.large one.

    There are infinitely many FISONs. What in the heck do you mean by using
    the word, "potentially"? It's as if you don't think infinity exists?

    "We introduce numbers for counting. This does not at all imply the
    infinity of numbers. For, in what way should we ever arrive at infinitely-many countable things? [...] In philosophical terminology we
    say that the infinite of the number sequence is only potential, i.e., existing only as a possibility." [P. Lorenzen: "Das Aktual-Unendliche in
    der Mathematik", Philosophia naturalis 4 (1957) p. 4f]

    Philosopy.

    "Until then, no one envisioned the possibility that infinities come in different sizes, and moreover, mathematicians had no use for 'actual infinity'. The arguments using infinity, including the Differential
    Calculus of Newton and Leibniz, do not require the use of infinite sets. [...] Cantor observed that many infinite sets of numbers are countable:
    the set of all integers, the set of all rational numbers, and also the
    set of all algebraic numbers. Then he gave his ingenious diagonal
    argument that proves, by contradiction, that the set of all real numbers
    is not countable. A consequence of this is that there exists a multitude
    of transcendental numbers, even though the proof, by contradiction, does
    not produce a single specific example." [T. Jech: "Set theory", Stanford Encyclopedia of Philosophy (2002)]

    Also philosophy.

    "Numerals constitute a potential infinity. Given any numeral, we can construct a new numeral by prefixing it with S. Now imagine this
    potential infinity to be completed. Imagine the inexhaustible process of constructing numerals somehow to have been finished, and call the result
    the set of all numbers, denoted by . Thus  is thought to be an actual infinity or a completed infinity. This is curious terminology, since the etymology of 'infinite' is 'not finished'." [E. Nelson: "Hilbert's
    mistake" (2007) p. 3]

    E. Nelson is clearly not a mathematician.

    According to (Gödel's) Platonism, objects of mathematics have the same status of reality as physical objects. "Views to the effect that
    Platonism is correct but only for certain relatively 'concrete'
    mathematical 'objects'. Other mathematical 'objects' are man made, and
    are not part of an external reality. Under such a view, what is to be
    made of the part of mathematics that lies outside the scope of
    Platonism? An obvious response is to reject it as utterly meaningless." [H.M. Friedman: "Philosophical problems in logic" (2002) p. 9]

    Possibly philosophy, more likely complete nonsense.

    "A potential infinity is a quantity which is finite but indefinitely
    large. For instance, when we enumerate the natural numbers as 0, 1, 2,
    ..., n, n+1, ..., the enumeration is finite at any point in time, but it grows indefinitely and without bound. [...] An actual infinity is a completed infinite totality. Examples: , , C[0, 1], L2[0, 1], etc. Other examples: gods, devils, etc." [S.G. Simpson: "Potential versus
    actual infinity: Insights from reverse mathematics" (2015)]

    Another philosopher?

    "Potential infinity refers to a procedure that gets closer and closer
    to, but never quite reaches, an infinite end. For instance, the sequence
    of numbers 1, 2, 3, 4, ... gets higher and higher, but it has no end; it never gets to infinity. Infinity is just an indication of a direction – it's 'somewhere off in the distance'. Chasing this kind of infinity is
    like chasing a rainbow or trying to sail to the edge of the world – you may think you see it in the distance, but when you get to where you
    thought it was, you see it is still further away. Geometrically, imagine
    an infinitely long straight line; then 'infinity' is off at the 'end' of
    the line. Analogous procedures are given by limits in calculus, whether
    they use infinity or not. For example, limx0(sinx)/x = 1. This means
    that when we choose values of x that are closer and closer to zero, but never quite equal to zero, then (sinx)/x gets closer and closer to one."
    [E. Schechter: "Potential versus completed infinity: Its history and controversy" (5 Dec 2009)]

    There may be a history to it, but there is no controversy, at least not
    in mathematical circles.

    The sequence of increasing circumferences (or diameters, or areas) of circles is potentially infinite because the circumference of a circle
    can become arbitrarily long, but it cannot be actually infinite because
    then it would not belong to a circle. An infinite "circumference" would
    have curvature zero, i.e., no curvature, and it could not be
    distinguished what is the inner side and what is the outer side of the circle.

    The length of periods of decimal representations of rational numbers is potentially infinite. The length is always finite although it has no
    upper bound. The decimal representation is equal to a geometric series,
    like 0.abcabcabc... = abc(10-3 + 10-6 + 10-9 + ...) which converges to the limit . A never repeating decimal sequence has an irrational limit.

    An interval of natural numbers without any prime number is called a
    prime gap. The sequence of prime gaps assumes arbitrarily large
    intervals but it cannot become actually infinite. None of the numbers n!
    + 2, n! + 3, n! + 4, ..., n! + n can be prime because n! = 123... n
    contains 2, 3, ..., n as factors already. Therefore the set of gaps has
    no upper bound. It is potentially infinite. It is not actually infinite however, because there does not exist a gap with no closing prime number because there is no last prime number.

    The set of these prime gaps is infinite, without qualification. Euclid
    could have told you that.

    Finally, the most familiar example is this: The (magnitudes of) natural numbers are potentially infinite because, although there is no upper
    bound, there is no infinite (magnitude of a) natural number.

    There are no "actual" and "potential" infinity in mathematics. The
    notions are fully unneeded, and add nothing to any mathematical proof.
    There is finite and infinite, and that's it.

    When I did my maths degree, several decades ago, "potential infinity" and "actual infinity" didn't get a look in. They weren't mentioned a single
    time. Instead, precise definitions were given to "finite" and
    "infinite", and we learnt how to use these definitions and what could be
    done with them.

    The only people who talk about "potential" and "actual" infinity are non-mathematicians who lack understanding, and pioneer mathematicians
    early on in the development of set theory who were still grasping after
    precise notions.

    And this logic just shows that YOU are not actually a mathematicians,

    You just don't undetstand the actual meaning of the words you use, but
    try to redefine them to non-sense, as that is all you understand.

    You are just too stupid to understand that the *INFINITE* set of FISONs
    (all of which are finite) does reach that which you say it can't, but
    the reason it can is just beyound your idiotic ability to comprehend,
    and you instance that your logic works just proves your utter stupidity.

    YOU BRAIN IS JUST TOO SMALL TO HANDLE THE CONCEPTS, and likely never can
    get there. That doesn't mean the concepts are wrong, but that YOU are

    All mathematicians whom you have disqualified above are genuine mathematicians.

    What you perhaps could understand is this simple example: As Cantor said actual infinity, for instance omegas and alephs and ℕ are fixed quantities. The set ℕ is invariable.

    Maybe Cantor did say this, as a pioneer early on in the development of
    set theory. Things have developed since then, and we see that there is
    nothing to be gained by construing infinite sets as "fixed quantities";
    there is no mathematical proof where such a concept makes the slightest difference.

    But all finite initial segments of natural numbers FISONs {1, 2, 3,
    ..., n} cover less than 1 % of ℕ.

    That is a thoroughly unmathematical statement. To talk about 1% of an
    infinite set is meaningless. To say "cover" in the context of set
    theory rather than topological spaces is inappropriate. Above all, to
    say "all finite initial segments" is unmathematical, since what is meant
    is not the set of FISONs, but the union of FISONs. Finally, it is
    wrong, absurdly wrong. The union of all FISONs _is_ N.

    Proof:

    No, not a mathematical proof. You have never studied maths to degree
    level, and have no idea what a mathematical proof looks like. Hint:
    have a look at some of Jim's posts where he posts rigorous proofs.

    {1, 2, 3, ..., 100n} is less than ℕ. That means the set of FISONs will never cover ℕ, nor will its union reach the invariable quantity.

    No, it doesn't mean that at all. The set of FISONs does indeed "cover"
    N, in the sense that their union is equal to N. A proof of this is
    trivial, well within the understanding of a school student studying
    maths.

    The set of FISONs is only potentially infinite, not a fixed quantity
    but growing over all finite bounds.

    This "potentially" and "actually" infinite has led you astray, away from
    the truth. They are solely historical notions, with no place in modern mathematics. The plain fact is that the set of FISONs is infinite - it
    can be put in a 1-1 correspondence with a proper subset of itself. That
    is all.

    ℕ cannot be covered by FISONs, neither by many nor by their union. If ℕ could be covered by FISONs then one would be sufficient. But for all we
    have: Extension by 100 is insufficient. Every union of FISONs which stay
    below 1 % stays below 1 %.

    mathematics from the theorems considered to be necessary. In recent

    attempts to justify large cardinal axioms by demonstrating their
    necessity for deriving certain propositions considered "concrete"."

    under thirty-five years of age in all fields of science and engineering. Friedman's contributions span all branches of mathematical logic
    (recursion theory, proof theory, model theory, set theory, and theory of computation). He is a generalist in an age of specialization, yet his
    theorems often require extraordinary technical virtuosity, of which only
    a few selected highlights are discussed. Friedman's ideas have yielded radically new kinds of independence results. The kinds of statements
    that were proved to be independent before Friedman were mostly disguised properties of formal systems (such as Gödel's theorem on unprovability
    of consistency) or assertions about abstract sets (such as the continuum hypothesis or Souslin's hypothesis). In contrast, Friedman's
    independence results are about questions of a more concrete nature

    "A potential infinity is a quantity which is finite but indefinitely
    large. For instance, when we enumerate the natural numbers as 0, 1, 2,

    grows indefinitely and without bound. [...] An actual infinity is a

    "Potential infinity refers to a procedure that gets closer and closer
    to, but never quite reaches, an infinite end. For instance, the sequence
    of numbers 1, 2, 3, 4, ... gets higher and higher, but it has no end; it
    never gets to infinity. Infinity is just an indication of a direction –
    it's 'somewhere off in the distance'. Chasing this kind of infinity is
    like chasing a rainbow or trying to sail to the edge of the world – you
    may think you see it in the distance, but when you get to where you
    thought it was, you see it is still further away. Geometrically, imagine
    an infinitely long straight line; then 'infinity' is off at the 'end' of
    the line. Analogous procedures are given by limits in calculus, whether
    they use infinity or not. For example, limx0(sinx)/x = 1. This means
    that when we choose values of x that are closer and closer to zero, but
    never quite equal to zero, then (sinx)/x gets closer and closer to one."

    There are no "actual" and "potential" infinity in mathematics.

    If you say so. :-P

    When I did my maths degree, several decades ago, "potential infinity" and "actual infinity" didn't get a look in. They weren't mentioned a single time. Instead, precise definitions were given to "finite" and
    "infinite", and we learnt how to use these definitions and what could be
    done with them.

    Sure. But this needs a context; usually (some sort of) set theory.

    For the inclusion-monotonic sequence of endsegments of natural numbers

    if every number k has infinitely many successors, as ZF claims, then the intersection is not empty. Therefore set theory, claiming both, is false.

    Inclusion monotonic sequences can only have an empty intersection if

    Further there are not infinitely many infinite endsegments possible

    a few selected highlights are discussed. Friedman's ideas have yielded radically new kinds of independence results. The kinds of statements
    that were proved to be independent before Friedman were mostly disguised properties of formal systems (such as Gödel's theorem on unprovability
    of consistency) or assertions about abstract sets (such as the continuum hypothesis or Souslin's hypothesis). In contrast, Friedman's

    result.

    When I did my maths degree, several decades ago, "potential infinity" and
    "actual infinity" didn't get a look in. They weren't mentioned a single

    "infinite", and we learnt how to use these definitions and what could be
    done with them.

    Sure. But this needs a context; usually (some sort of) set theory.

    The only people who talk about "potential" and "actual" infinity are

    Find a FISON that surpasses 1 % of ℕ. Fail.
    Find a union of FISONs that surpasses 1 % of ℕ, i.e. which multiplied by
    100 is |ℕ|. Fail. However that must be a finite union, because the union surpassing 20 % of ℕ must be larger. That cannot happen with an infinite union.

    So? it doesn't mean that ZF has made it an axiom that the set of Natural Numbers exist, he has made his Axiom of Infinity to be designed so that
    the existance of the Natural Numbers can be derived from it. You confuse
    cause from effect.

    IT is good to know where you are trying to go, or it can be hard to get
    there.

    IF you claim that the axiom of infinity is NOT valid, then why do you
    keep on using the results of it in your logic? One of your problems is
    you have ADMITTED that you "logic" isn't axiomized (since you admit you
    can't provide a set of actual axioms to define it) and thus you admit
    that your "logic" isn't actually LOGIC. Your "Theorem" can't be actually
    a Theorem, as you don't have any axioms on which to prove it.

    There isn't one, but that doesn't matter,

    Show me a Natural Number that is bigger than Aleph_0 / 100?

    It doesn't exist, because Aleph_0 is infinite, and an infinite number
    divided by ANY finite value is still that infinite value, and thus there
    is no finite value greater than that.

    This doesn't give you your "dark numbers" as "non-defined finite
    numbers", but shows that your logic is just broken.


    So, all you prove is that a finite subset of an infinite set doesn't
    cover all of the infinite set.

    Your logic can't handle *EVERY* FISON at once.

    Show one FISON that is larger than 1 %.

    Doesn't exist, and doesn't need to.

    Again, you are just proving your stupidity.

    The creation of the infinite set of N isn't based on having an infinite
    member in it, but on having an infinite number of members, that build
    something having properties different from any of its individual member.

    Your "logic" can't handle the difference between the set itself, and the individual members, and that is what make it blow itself up into

    None of the above extracts is about mathematics. If there were such

    like that. Nobody in this discussion has so far attempted to cite
    such a result.

    When I did my maths degree, several decades ago, "potential
    infinity" and "actual infinity" didn't get a look in. They weren't
    mentioned a single time. Instead, precise definitions were given to
    "finite" and "infinite", and we learnt how to use these definitions
    and what could be done with them.

    Sure. But this needs a context; usually (some sort of) set theory.

    The only people who talk about "potential" and "actual" infinity are
    non-mathematicians who lack understanding

    Like those mentioned above?

    OK, and mathematicians in their time off. ;-)


    Oh, how about yin-yang ad-infinitum,
    a simple and graphical example of
    something that is, in the infinite,
    not what it is, in the limit,
    that it's actual infinite limit,

    What do you mean by the "yin-yang ad-infinitum", exactly?

    I'm not even sure how you would define, or distinguish "actual infinite
    limit" and "potential infinite limit". Do such things already have
    accepted mathematical definitions?

    It's also well known that a limit frequently has properties not in any of
    the terms. For example, the limit of a sequence of rational numbers is
    often irrational. Is this what you meant?

    Of course. Here is a simple example, accessible to every student who is

    For the inclusion-monotonic sequence of endsegments of natural numbers

    False. Where do you get such an idea from? Such sequences have an empty intersection if there is no element which is a member of each set in the sequence. This is trivially true for the sequence of endsegments of the natural numbers.

    Therefore the empty intersection of all requires the existence of
    finite terms which must be dark.

    Further there are not infinitely many infinite endsegments possible
    because the indices of an actually infinite set of endsegements without
    gaps must be all natural numbers.

    That's meaningless gobbledegook.

    Of course. Here is a simple example, accessible to every student who is

    For the inclusion-monotonic sequence of endsegments of natural numbers

    Of course. But do you know what inclusion-monotony means? E(n+1) is a
    proper subset of E(n): {n+2, n+3, n+4, ...} c {n+1, n+2, n+3, n+4, ...}.
    Here the intersection cannot be empty unless there is an empty endsegment.

    As for the intersection of all endsegments of natural numbers, this is obviously empty.

    Of course. ∩{E(k) : k ∈ ℕ} = { }.
    But for all definable endsegments the intersection is infinite, and from endsegmnet to endsegment only one number is lost, never more! Therefore
    the general law of mathematics
    ∀k ∈ ℕ : E(k+1) = E(k) \ {k+1}
    or
    ∀k ∈ ℕ : ∩{E(0), E(1), E(2), ..., E(k+1)} = ∩{E(0), E(1), E(2), ..., E(k)} \ {k+1}
    proves that the empty intersection requires finite intersections
    preceding it. Unless you claim that the general law does not hold for ∀k
    ∈ ℕ.

    Therefore set theory, claiming both, is false.

    Set theory doesn't "claim" both. Set theory doesn't "claim" at all. It
    has axioms and theorems derived from those axioms. If one accepts the axioms, and nearly all mathematicians do, then one is logically forced to accept the theorems, too.

    But the theorems contradict the general law of mathematics.

    See above.

    Such sequences have an empty
    intersection if there is no element which is a member of each set in the sequence. This is trivially true for the sequence of endsegments of the natural numbers.

    It is trivially true that only one element can vanish with each endsegment.

    Therefore the empty intersection of all requires the existence of
    finite terms which must be dark.

    That isn't mathematics. Jim proved some while ago that there are no dark numbers, in as far as he could get a definition of them out of you.

    When all contents is appearing as an infinite sequence of indices then

    Such sequences have an empty

    It is trivially true that only one element can vanish with each

    IF you claim that the axiom of infinity is NOT valid, then why do you
    keep on using the results of it in your logic? One of your problems is
    you have ADMITTED that you "logic" isn't axiomized (since you admit

    admit that your "logic" isn't actually LOGIC. Your "Theorem" can't be

    No,

    Show one FISON that is larger than 1 %.

    There isn't one, but that doesn't matter,

    Show me a Natural Number that is bigger than Aleph_0 / 100?

    It doesn't exist, because Aleph_0 is infinite, and an infinite number
    divided by ANY finite value is still that infinite value, and thus
    there is no finite value greater than that.

    This doesn't give you your "dark numbers" as "non-defined finite
    numbers", but shows that your logic is just broken.

    [...]

    WM must think that Aleph_0 is some really big natural number.

    well, he admitted that he doesn't think infinity exists, so those

    Only valid for finite sets.

    Why? What changes the basics? The intersection is only empty, when no

    As for the intersection of all endsegments of natural numbers, this is
    obviously empty.
    But for all definable endsegments the intersection is infinite, and from
    endsegmenet to endsegment only one number is lost, never more!
    And nobody said otherwise, since there are infinitely many segments.

    Infinitely many endsegments need infinitely many indices. Therefore no
    natural number must remain as content in the sequence of endsegments.

    Unless you claim that the general law does not hold for ∀k ∈ ℕ.
    It does not hold for the infinite intersection.

    Why not?

    Inclusion monotonic sequences can only have an empty intersection if
    they have an empty term.
    False.

    Simple logic. For an empty intersection, there must be infinitely many endsegments. That means no natural number can remain in the content. If
    a number n remained, then it would impose an upper limit on the sequence
    of indices.

    It is trivially true that only one element can vanish with each
    endsegment.
    Which noone contradicted.

    Then the empty intersection is preceded by finite intersections.

    Jim "proved" that when exchanging two elements O and X, one of them can
    disappear. His "proofs" violate logic which says that lossless exchange
    will never suffer losses.
    Wrong. The limit of the harmonic series is zero, even though none of the terms are.

    There is no exchange involved.

    That's a simple fact. The sequence of natural numbers 1, 2, 3, ..., n,
    n+1, ...
    cannot be cut into two actually infinite sequences, namely indices and
    contents.
    Why should it?

    Because an infinite sequence of indices followed by an infinite sequence
    of contentent would require two infinite sequences.

    When all contents is appearing as an infinite sequence of indices then
    no number can remain in the contents.
    Yes, there are no more numbers after the naturals???

    So it is. The claim of infinitely many infinite endsegments is false.

    According to set theory every set has a fixed set of elements, not

    No. Ask a set theorist of your choice. Sets are absolutely invariable.

    Omega is a limit ordinal not a successor.

    But the natural numbers are invariable. For every n, there is n+1
    which is not created but simply exists.

    Great for every n which are elements of N but omega is not an element of
    N. In the naturals, n+1 is usually axiomatic and n-1 is a theorem. In
    the infinite ordinals omega+1 is axiomatic and omega-1 is undefined or
    not existent.

    Axiomatic? It is simply mathematical reality, but only for visible
    numbers. The axioms have been designed to reproduce this mathematical

    Zero is the smallest in the natural number class, omega is the
    smallest of the infinite number class. Neither has a predecessor in
    its class.

    Are the natural numbers fixed or do they evolve?

    Neither

    There is no third alternative.

    they are the smallest infinite set.

    The set of prime numbers is infinite but smaller because it is a proper
    subset. It has less than 1 % content.

    Not all sets are finite

    The sequence ℕ is infinite, but when cut at any n, then the first part
    is finite and the second part is actually infinite.

    Infinitely many infinite endsegments are impossible in actual infinity.

    Why? What changes the basics? The intersection is only empty, when no

    The empty (inf.) intersection is not a segment.
    If none is empty, then other numbers must be inside. Contradiction.
    No number is an element of all segments.

    As for the intersection of all endsegments of natural numbers, this

    But for all definable endsegments the intersection is infinite, and
    from endsegmenet to endsegment only one number is lost, never more!
    And nobody said otherwise, since there are infinitely many segments.
    Infinitely many endsegments need infinitely many indices. Therefore no natural number must remain as content in the sequence of endsegments.
    Only insofar as every number eventually "leaves" the endsegments.
    This however does not imply and empty endsegment, since there inf. many
    of both naturals and therefore endsegments.

    It does not hold for the infinite intersection.
    Why not?
    Sorry, I lost track. Which law?

    Inclusion monotonic sequences can only have an empty intersection if >>>>> they have an empty term.
    False.
    Simple logic. For an empty intersection, there must be infinitely many endsegments. That means no natural number can remain in the content. If
    a number n remained, then it would impose an upper limit on the sequence
    of indices.

    It is trivially true that only one element can vanish with each
    endsegment.
    Which noone contradicted.
    Then the empty intersection is preceded by finite intersections.
    Does not follow.

    Jim "proved" that when exchanging two elements O and X, one of them
    can disappear. His "proofs" violate logic which says that lossless
    exchange will never suffer losses.
    Wrong. The limit of the harmonic series is zero, even though none of
    the terms are.
    There is no exchange involved.
    Same reason: the limit may have different properties than the terms.

    That's a simple fact. The sequence of natural numbers 1, 2, 3, ..., n,
    n+1, ...
    cannot be cut into two actually infinite sequences, namely indices and
    contents.
    Why should it?
    Because an infinite sequence of indices followed by an infinite sequence
    of contentent would require two infinite sequences.
    But this never happens. There can be no infinite starting segment short
    of N itself, and nothing can follow that.

    When all contents is appearing as an infinite sequence of indices then
    no number can remain in the contents.
    Yes, there are no more numbers after the naturals???
    So it is. The claim of infinitely many infinite endsegments is false.
    There are infinitely many naturals though. I fail to picture your
    imagination.

    E(1) = {1, 2, 3, ...}
    E(2) = {2, 3, 4, ...}
    ...
    E(k-1) = {k-1, k, k+1, ...}

    are all infinite and then you just give up?

    No, they are subsets of the same cardinality. There is no contradiction.

    They remain infinite. But infinitely many endsegments require all

    In the sequence of end.segments of ℕ there is no number which empties

    Then there cannot exist a sequence of endsegments obeying
    ∀k ∈ ℕ: E(k+1) = E(k) \ {k+1} for all k ∈ ℕ and getting empty.
    No term of the sequence is empty, if you mean that.

    Then not all natnumbers are outside of content and inside of the set of indices.

    and there is no number which is in common with all its end.segments.
    Therefore all numbers get lost from the content and become indices.
    WDYM "become"? There is no point at which all naturals would be

    The endsegment E(n) loses its element n+1 ad becomes E(n+1).

    ℕ has only infinite end.segments.
    Then it has only finitely many, because not all numbers get lost from
    the content.
    Huh? No. Then not all numbers would be "indices".

    Then there are only finitely many indices.

    The intersection of all (infinite) end.segments of ℕ is empty.
    What is the content if all elements of ℕ have become indices?
    There is no such endsegment.

    Right.

    No, after the natural numbers comes omega plus one. Omega *IS* the
    order type of the natural numbers.

    <facepalm>

    Hint: 0 < 1 < 2 < 3 < ... < ω < ω+1 < ω+2 < ω+3 < ...

    ω is the first infinite ordinal number. It comes after all finite
    ordinal numbers and can be considered as their limit. The order type
    is another meaning of ω.

    Right.

    Nothing from that implies that there is a "largest natural number". Not
    at all. :^)

    Indeed.

    If none is empty, then other numbers must be inside. Contradiction.
    No number is an element of all segments.
    But what numbers are inside if all natural numbers are outside?
    Inside what? Inside each segment are infinitely many naturals. Mind
    your quantifiers: It is not required that the intersection be nonempty.

    Infinitely many endsegments need infinitely many indices. Therefore no
    natural number must remain as content in the sequence of endsegments.
    Only insofar as every number eventually "leaves" the endsegments.
    But what remains?
    In what? The intersection is empty.

    This however does not imply and empty endsegment,
    What remains?
    Nothing "remains". There is no end, only a limit.

    since there inf. many of both naturals and therefore endsegments.
    Infinitely many numbers leave. All elements of ℕ leave.
    Yes, in the limit.

    Unless you claim that the general law does not hold for ∀k ∈ ℕ. >>>> It does not hold for the infinite intersection.
    Why not?
    Sorry, I lost track. Which law?
    The law that the intersection gets empty but only by one element per
    term.
    Well, in the limit (sigh) infinitely many numbers have been "lost".

    It is trivially true that only one element can vanish with each
    endsegment.
    Which noone contradicted.
    Then the empty intersection is preceded by finite intersections.
    Does not follow.
    It follows from the law that only one element per term can leave.
    Care to write out that deduction?

    Jim "proved" that when exchanging two elements O and X, one of them
    can disappear. His "proofs" violate logic which says that lossless
    exchange will never suffer losses.
    Wrong. The limit of the harmonic series is zero, even though none of
    the terms are.
    There is no exchange involved.
    Same reason: the limit may have different properties than the terms.
    There is no limit involved when counting the fractions.
    It is an infinite "process".

    That's a simple fact. The sequence of natural numbers 1, 2, 3, ...,
    n, n+1, ...
    cannot be cut into two actually infinite sequences, namely indices
    and contents.
    Why should it?
    Because an infinite sequence of indices followed by an infinite
    sequence of contentent would require two infinite sequences.
    But this never happens.
    An infinite set of infinite endsegments happens according to matheology.
    It requires two infinite sequences.
    No, it doesn't. There is no "infinitieth" segment.

    The claim of infinitely many infinite endsegments is false.
    There are infinitely many naturals though.
    But all must be in the set of indices, if there are infinitely many endsegments. But infinitely many must be in the set of contents, if all endsegments are infinite.
    Those are the same set N.

    Now this is gibberish. What do those terms mean? Are you referring

    The set of prime numbers is infinite but smaller because it is a

    Any special reason for that figure?

    No term of the sequence is empty, if you mean that.

    Untrue. The sequence is, unfathomably, infinite.

    and there is no number which is in common with all its endsegments.
    Therefore all numbers get lost from the content and become indices.
    WDYM "become"? There is no point at which all naturals would be counted

    The endsegment E(n) loses its element n+1 ad becomes E(n+1).

    ℕ has only infinite endsegments.

    Huh? No. Then not all numbers would be "indices".
    Then there are only finitely many indices.
    Contradiction. There are inf. many.

    The intersection of all (infinite) end.segments of ℕ is empty.
    What is the content if all elements of ℕ have become indices?
    There is no such endsegment.
    What element of ℕ does not become an index?
    omega is not an element of N.

    Here we talk about endsegments and the natural order.

    You seem to THINK that sets,

    The multiplication above concerns the set, not only the numbers we know.


    they are the smallest infinite set.

    The set of prime numbers is infinite but smaller because it is a
    proper subset. It has less than 1 % content.

    It may SEEM smaller, but it turns out it is of the same countable
    infinite cardinality.

    It turns out that countable cardinality is not able to distinguish the
    sets of natural numbers and of even numbers. But mathematics. Every set
    {1, 2, 3, 4, 5, ..., n} contains roughly twice the even numbers. This
    holds for all n. More are not available. Hence it holds for the infinite
    set.

    Any questions about mathematics?

    I do not apply any limit. I apply simply all natural numbers. Note that

    It has an infinite number of elements, and that number happens to be

    That implies the impossibility to extract all elements of contents in

    No, you just need "extract/apply" infinitely many,
    which means all natural numbers. Not even one must be missing from the
    set of indices.
    In particular it means there is no largest one.

    That destroys Cantor's approach. His sequences do not exist:
    "thus we get the epitome (ω) of all real algebraic numbers [...] and
    with respect to this order we can talk about the nth algebraic number
    where not a single one of this epitome (ω) has been forgotten." [E.
    Zermelo: "Georg Cantor – Gesammelte Abhandlungen mathematischen und
    philosophischen Inhalts", Springer, Berlin (1932) p. 116]
    What does this have to do with Aleph_0?
    It means that no limits are involved but that all not yet used content
    of endsegments must become indices. Not all endsegments can be infinite.
    Yes they can, because there are an infinity of them.

    That doesn't make it true for N and G.
    I am not interested in these letters but only in all natural numbers.
    All natural numbers are twice as many as all even natural numbers. If

    is true also for them.
    No. For n->oo,
    Every n is finite.
    The *set* of all of them isn't.

    G is both the set {2, 4, ..., 2n} and {2, 4, ..., 42n};
    indeed, {2, 4, ..., 2kn} for every k e N.
    And all of them can be denoted by n.
    All what?

    If these sets are not fixed, then there is no bijection possible.
    They are fixed for every single k and n->oo, they are the same even.

    If Cantor has constructed a sequence containing all even numbers of the original set ℕ, then the doubled even numbers are missing.

    Nope. You are just showing your stupdity, and that you are too stupid to
    see that stupidity.

    Your "logic" is claimed to be based on common-sense, but is actually

    Let f(x) = 2x/x. The limit of the ratio is 2. The ratio of the limit is undefined. In mathematics we use the limit of the ratio.

    No, we can say that the limit of 2x/x is 2 even at x == 0, where the
    expression itself is singular. We can then talk about the continous
    function of the limit of the expression, which is a DIFFERENT function
    (since it differs at the "value" at x==0) but "close enough" for most
    things.

    Maybe in YOUR naive mathematics you just assume that sort of thing, but
    when you do, and are dealing with infinite sequences, you get
    contradictions.

    You do know that the sum of an infinite series of terms can change its
    value based on the order you add up the terms? And thus you need to be
    careful about how you approach limits of infinite series.

    There is a basic law: When a sequence of regular distances is multiplied

    The interval (0, ω)*2 becomes (0, ω*2) with ω in the middle. Below ω the newly created even numbers cannot be inserted, because more than all

    I've yet to see any useful application of the notion of potential

    They use it too. Otherwise doubling of all natural numbers generates new numbers. But they are too stupid to understand that.

    No, it DOES have a baring on how infinity "works", but that seems to be

    Your logic is based on the concept that infihity isn't actually

    *IS* a measurable part of the whole, just an inconceivably small portion.

    IT is YOUR method that is insufficient to handle that actual nature of

    The two sets do not have a measurable difference, because they have the
    same number of elements. as can be shown with the proper pairing between
    them. *YOU* only *THINK* they are different, because your logic can't do

    No, it depends on completeness. If all natural numbers are there such

    ⎜ ℕ is the set of finite ordinals.

    Of all. None can be added. If all are doubled, then 50 % odd nubers are deleted, 50 % even numbers are added. Because the total sum remains

    No it would be the regualar distances in (0, omega), since you excluded

    Between all natural numbers, there is a regular distance. When doubled,
    the new ones do not fit between the old ones and ω because nothing fits between ℕ and ω.

    your starting premise is just

    to double all numbers which fit between 1 and ω.

    The interval (0, ω)*2 becomes (0, ω*2) with ω in the middle. Below ω
    the newly created even numbers cannot be inserted, because more than
    all even natural numbers do not exist in actual infinity.

    Every contrary opinion is based on potential infinity.


    Nope, your "opinion" is just based on your

    correct understanding that all between 1 and ω is available for doubling

    Die Menge G = {n*2 e IN : n e IN} ist einfach eine (echte) Teilmenge der natürlichen Zahlen, die (per definitionem) genau die sog. /geraden (natürlichen) Zahlen/ enthält.

    but cannot change the number of numbers,

    Das wiederum ist richtig. Es gilt nämlich (wegen IN ~ G):

    |IN| = |G|
    bzw.
    card(IN) = card(G) .

    therefore creates even numbers.

    Nö, die werden nicht "created", Du Depp, sondern lediglich mit Hilfe des

    Das "Aussonderungsaxiom" sichert die Existenz der Menge G = {n*2 e IN :

    They do not fit below ω

    If there is space, then it is filled before doubling already. Why
    shouldn't it?

    ∀n ∈ ℕ: 2n > n. All numbers are doubled. Their number remains the same (not only the cardinality, but the reality). Half of all are deleted.

    ∀n ∈ ℕ: 2n > n. All numbers are doubled. Their number remains the same (not only their cardinality, but their reality). Half of all, the odd
    numbers, are deleted. Half must be new.

    In potential infinity they simply are added by expanding the sequence
    because there is no ω. I actual infinity there is no space available
    below ω.

    Doubling of all n deletes the odd numbers but cannot change the number
    of numbers, therefore creates even numbers. They do not fit below ω.
    Remember: nothing fits between them and ω.

    No. There is no x e N such that 2*x >= omega. You have listed two
    consecutive infinities on the right.

    There is a basic law: When a sequence of regular distances is
    multiplied by 2, then a sequence of regular distances results.

    Which isn't applicable, since their isn't such a "regular distance"

    Between all natural numbers, there is a regular distance. When
    doubled, the new ones do not fit between the old ones and ω because
    nothing fits between ℕ and ω.

    But omega isn't a natural number, so the space between the ... and
    omega isn't the same as the space between two consecutive natural
    numbers.

    Maybe. But the space between the natural numbers is doubled while the accessible space remains constant in actual infinity.

    Yes, and double infinity is still just infinity.


    And the distance between the ... and omega *IS* big enough to fit the
    doubling of all the numbers (without needing to make any new ones).

    If there is space, then it is filled before doubling already. Why
    shouldn't it?

    No, the numbers are of a different class, and the space is inherent in
    the classes.

    The numbers in the ... are all finite (but an infinite number of them)
    omega is infinite (countably infinite). There is always an infinite
    space between the infinite set of Natural Numbers and that first
    Countably infinite number.



    your starting premise is just

    to double all numbers which fit between 1 and ω.

    Which are still just the even numbers between 1 and omega.

    ∀n ∈ ℕ: 2n > n. All numbers are doubled. Their number remains the same (not only the cardinality, but the reality). Half of all are deleted.
    Half are new.

    So? Double and Half of infinity is still infinity.

    You are just stuck on our false lies from your finite thinking.


    correct understanding that all between 1 and ω is available for
    doubling and nothing can be inserted.

    And nothing NEEDS to be inserted.

    It cannot. Therefore half of the results is larger than ω.

    YOu *THINK* it can not, because your brain is to small to understand.

    Therefore, you have invented out of your own imagination the lie of
    "dark numbers" to try to explain what you don't understand.

    All that does is prove you don't understand what you are talking about.

    Your stupidity is so great, you just can not imagine things being other
    than what you think they are, which is the highest form of ignorance.

    rational numbers || > |#|.

    That is obviously wrong.

     The rule of construction yields the number of integers || = 2|| + 1 and the number of fractions || = 2||2 + 1 (there are fewer rational numbers # ). Since all products of rational numbers with an irrational number are irrational, there are many more irrational numbers than
    rational numbers || > |#|.

    Yes, there are more irrational numbers thn rational numbers,

    geometric points  in every interval (n, n+1] and with at most a small
    error same number of odd numbers and of even numbers in every finite
    interval and in the whole real line.

    There is no infinite set smaller than ℕ.

    {2,3, 4, ...} is smaller by one element.

    Which, since that size is infinite, is the same size.

    An example is the pocket calculator where all numbers after

    "Potential infinity refers to a procedure that gets closer and closer
    to, but never quite reaches, an infinite end. For instance, the sequence
    of numbers 1, 2, 3, 4, ... gets higher and higher, but it has no end; it
    never gets to infinity.[...]
    Completed infinity, or actual infinity, is an infinity that one actually reaches; the process is already done. For instance, let's put
    braces around that sequence mentioned earlier: {1, 2, 3, 4, ...}. With
    this notation, we are indicating the set of all positive integers." [E. Schechter: "Potential versus completed infinity: Its history and
    controversy" (5 Dec 2009)]

    Note: "With this notation, we are indicating the set of all positive
    integers." That implies, with the other notion we are not.

    Multiplying all its elements by 2
    creates new elements.

    No. it doesn't.

    If all are there and all are doubled, then greater elements are
    produced. This is the mathematics of 2n > n. That you cannot accept it,
    shows that your set theory contradicts mathematics.

    the same as any other set,
    which is to say,
    it is (has been, will be) completeᵂᴹ.

    Then new numbers must be outside.

    There are no new numbers.

    2n > n proves new and greater numbers than are doubled.

    A step is never from finite to infinite.
    Therefore, a step never crosses ω

    Therefore no ω does exist. That is the only alternative. Potential infinity.

    By logic I mean logic. Since the small numbers are always covered by the greater FIS=ONs, the smaller FISONs can be dropped. Either the complete

    is not a FISON, or it is not produced by FISONs.

    I am able to show to you
    a finite sequence of claims in two parts.

    One part is claims about intentions.
    What ω is intended to mean.
    What ω-1 is intended to mean.
    What ordinal is intended to mean.
    What finite is intended to mean.
    What those are among which λ is intended to refer.

    These claims can be known by
    people who know what is intended.
    There might be people who don't know.
    You (WM), for example.
    But, for people who know, it is knowledge,
    if not awe.inspiring knowledge.

    Seeing ω plays no part in that knowledge.

    Another part is claims which are not.first.false,
    and which can be seen to be not.first.false
    by examining them on a printed page or
    scratched in the sand.
    Patterns like ⟨ P P⇒Q Q ⟩ can be perceived
    and known to be not.first.false
    as certainly as 7×11×13 = 1001

    Seeing ω plays no part in that knowledge.

    But if ω is assumed to exist,
    then there is a set cotaining ω elements.

    ...then there is a set of all finite ordinals.

    ω = ω is true, but not helpful.

    From this set one element can
    be subtracted.

    For ⟦0,ω⦆, there is
    emptier.by.one ⟦1,ω⦆

    Also, more generally,
    there is no infiniteˢᵉᵗ smaller than ℕ

    Therefore ℕ \ {1} is finite.

    No.
    If ℕ\{1} was finite, then
    a larger finite ordinal k would exist.

    However,
    all finite ordinals are in ℕ

    Ordinals 0 to k and k+1 and k+2 are in ℕ
    ⟦0,k+1⦆ is alleged to be
    a subset of ℕ which is larger than ℕ

    You (WM) introduce
    negative cardinality (darkᵂᴹ numbers)
    in an attempt to fit these claims together.
    Matheologians don't use anything so fancy,

    "cannot be counted by FISONs"

    That "definition" violates to definition that set don't change.
    So it is. But if infinity is potential, then we cannot change this in
    order to keep set theory, but then set theory is wrong.

    Some may talk of a growing set, but then you can't use any logic based

    Correct. If infinity is potential. set theory is wrong.
    And that is why set theory doesn't talk about "potential infinity".

    So, you agree that your logic makes everything worthless.

    Since I hope you agree that being able to do simple math is useful, and
    thus small numbers are useful even if we can't find the biggest.

    THus, your false premise that without a biggest, the smaller are
    worthless is just incorrect, and thus your conclusion is incorrect.

    It may be that without being able to have a biggest Natural Number you
    think that it makes that set worthless, but that is just your error.

    The problem is that a logic that can only work if it can find the "last"
    number of a set is itself worthless if the sets you are trying to deal
    with are infinite, so don't have that property.

    So, all you are doing is proving that your own logic is faulty and
    worthless if you want to deal with infinite sets.

    There isn't anything wrong with the infinite sets, as with a PROPER
    logic, they fully work, it is just your broken, and ill-defined, logic
    that you have your problems.

    Set theory doesn't distinguish the two, because it doesn't matter to set theory, The set has either the final result of the "potential" infinity description, or just is the actual infinite set.

    Note, even in actual infinity, every Natural Number has Aleph_0
    successors, as there is no "last" Natural Number(s), even though all exist.

    Your concept of having a last (or even a finite tail) is just a property
    of finite sets, and doesn't apply to infinite sets.

    All you have shown is that "Actual Infinity" can't be looked at by a
    logic that only deals with finite sets.

    Such a logic can potentially look at "Potential Infinity", as each set
    allong the way is a finite set, and getting to infinity is only at the
    eventual completion, so the logic only breaks "in the limit".

    There is non, because you need almost ALL of the FISONS to do that,

    The set of required FISONs is well defined because for every FISON we

    But YOU can only do that for a finite number of them, not almost all of

    Wrong. Every set of ordinal numbers has a first one.


    Further, according to set theory, every well defined set of ordinal
    numbers has a first element. The FISONs F(n) must obey this theorem
    because they can be ordered by their greates ordinals n.

    You simply violate this fact.

    Where?

    By not giving a first one.

    The error is your handwaving claim that infinitely many FISONs are
    required. Infinitely many failures will not yield a success.


    And YOUR "handwaving" just shows your stupidity, and inability to
    understand your stupidity.

    I don't "Handwave" the claim of needing infinitely many FISONs,

    I can prove that no FISON is required. That is mathematics.

    Yea, it match individual elements but also look that the ENTIRE mapping

    This difference is something that you apparently can't see, because you

    We establish the pattern individually, and then show that the pattern
    can be repeated indefinitely, and thus the matching happens as a
    collective whole. It can't complete if you don't move from the
    individual step to the collective step.

    It needs to be able to move from "for any" n, to "for all", which is NOT
    an "individual, one by one" operation.

    I guess when we talk about the set { 0, 1, 2, 3, ... } you must be
    defining "4" as a "dark number" as that was the point we shifted from

    The basic problem with your "dark numbers" is that no number itself is

    THus, your logic is build on ignorance and nonsense.

    No. Every number that is defined in a system by its FISON is visible.
    Many numbers smaller than 10^99 are defined on the pocket calculator. No greater number can be defined in that system.

    The basic problem with your "dark numbers" is that no number itself is "dark", the collective nature is just how we chose to use that number.

    It is how we *can* chose them.

    Your "Darkness" is just a result of your ignorance, like "darkest

    Your "Dark Numbers" are just the numbers your logic can not handle.

    You have not understood anything. All numbers can be used collectively

    But All of the numbers can also be used individually too. You just can't
    use them all at once with your logic, since your logic can't actually
    handle an infinite set.

    Your seem to think that the need to handle an infinite set of numbers,
    that each could be used individually, collectively means these numbers
    couldn't be used individually,

    It is just YOUR LOGIC that is "dark" and can't do what you need it to do.

    But your conclusion, that some Natual Numbers can't be used individually doesn't follow.

    There is no execption, but there doesn't need to be, as it is an
    accepted fact that all finite sets of numbers are not infinite, so no
    finite set of numbers is teh full set of the Natural Numbers.

    All you are doing is proving your logic can't handle actually (or even potentially) infinite sets.

    The union of all FISONs does not cover ℕ. Otherwise Cantor's theorem

    Sure it does, but you need to use an INFINITE set of them, and thus can
    not individually name all of them at once. That doesn't mean that there
    are any that can't be named individually.

    No, set theory claims that the set is infinite. Note, your problem is
    you are trying to use a non-set compatible distinction between actual
    and potential infinity, which blows up your logic.

    You confuse the individual numbers with the set they belong to, and
    apparently are too stupid to understand your error.

    The bijection uses an infinite set of numbers, and while each member of
    that set has an infinite number of successors, there are no numbers that
    are above the contents of the whole set. A property of the infinite,
    which your Naive Logic can't handle.n

    That your logic can't handle actually infiite sets is YOUR problem, and

    There is no problem using all the Aleph_0 successor, it just means you

    It isn't the Numbers that change to be use collectively, it is the logic
    on those numbers that change. Thus no Natural Number needs to be dark,
    you just need to use logic that can handle infinite sets.

    But *YOU* with your finite logic CAN'T go through every FISON

    No matter how many FISONs you have gone through, there are still Aleph_0
