Nobody said that there were. Why do you bring up irrelevant points? Are you trying to say the |F| isn't greater than all members of the set F?
http://en.wikipedia.org/wiki/Aleph_number
Aleph-null is by definition the cardinality of the set of all natural numbers, and (assuming, as usual, the axiom of choice) is the smallest of all infinite cardinalities.
What a truly marvelous talent you have for juxtaposing two statements that aren't related.
So we need two things here which are: 1) Natural Numbers 2) The axiom of choice
Need it for what? By the way, saying that something "is by definition..." isn't the same as saying something "is defined as".
(if there is no natural choice (an example of natural choice is: the smallest member of every nonempty set of natural numbers)).
"if there is no natural choice..." -- yeah, then what? You didn't finish this statement. And for that matter, what does a "natural choice" have to do with the Axiom of Choice?
So by (1) and (2) we have a collection of different finite sizes, where each size is exactly a finite cardinal.
Are you equating the set of natural numbers to a set of sizes? That is totally unnecessary and irrelevant.
However, that isn't relevant. Nothing in your statement, "|N| > any member of N = {1, 2, 3,...}" depends on N being the set of finite cardinals.
Only by using the existence of a collection of infinitely many finite cardinals, we can say that the smallest transfinite cardinal is exactly the cardinal that is greater than any finite cardinal
Nonsense, if for no other reason than
all the transfinites are greater than any finite cardinal. The smallest transfinite "isn't exactly" the cardinal that is greater than any finite cardinal; it is not unique in that respect.
You have taken what is fundamentally a simple idea, turned it inside out, then twisted it to match some warped view you have. Stop that.
...or in other words |N| > any member of N, where any member of N does not exist if it is not at least a finite cardinal (ordinals also do not exist without cardinality, in the case of natural numbers, so only cardinality is important here)).
They have existed and will continue to exist without this being a prior condition.
Since |N| > any member of N is the basic rule that enables the existence of |N| as a transfinite cardinal in the first place
It isn't.
it can be generalized to |X| > any member of X iff any member of X is a cardinal (finite or not) and |X| is a transfinite cardinal.
As already demonstrated, this is a false statement. The set of reals, for example, satisfies the left-hand side of your IF-AND-ONLY-IF proposition but not the right.
This generalization does not hold if |X| is a finite cardinal for example: |4| > any member of S={1,2,3,4} is false.
Also F case is not relevant to "|X| > any member of X" definition since F members are not cardinals.
There is no such requirement in your proposition that F consist only of cardinals. You are seeing things that are not there.
There is noting "in general" about it. That would be the set of the finite cardinals. Note, too, that while you might consider this weakly to be a definition of a set we'll call N, it is not a definition of the set of finite cardinals.
"|X| > any member of X" is relevant as general definition for transfinite cardinals only if the members of the collection are themselves cardinals and |X| is a transfinite cardinal.
In the real world of mathematics, this isn't the case.
In general, there is no general extension form the finite to the non-finite, and this is exactly why Cantor's reasoning fails (he forces the finite in order to define the non-finite. We do not need more that Dedekind-infinite (
http://en.wikipedia.org/wiki/Dedekind-infinite_set ) in order to show that there cannot be such an extension).
Which part, exactly, did Cantor get wrong?
It's great how you just make this crap up, doron, without much thought about what you are actually saying. Your statement wasn't even in the correct grammatical form to be a definition. Be that as it may, what in your "definition" constrains |N| to be exactly Aleph-null? Not much of a definition, now is it, if it doesn't actually make something specific.
I show that Cantor's reasoning does not hold water, because it is based on forcing the finite on the non-finite.
No, you showed again how little you understand English, Mathematics terminology, logic, and reasoning.
Did you perhaps want to say something like "|N| is the smallest transfinite cardinal number, where N is the set of positive integers"? You didn't. You didn't even come close.
No, I want to say that N collection simply does not exist if each member of it is not at least a finite cardinal > 0.
So, the set N = {0, 1, 2, 3} does not exist. That's an interesting new set theory you have there.
