I assumed 2. for convienience ( I also make assumption for infinity

consistently ).
It is difficult to answer; because, as soon as you accept the
Sorry, this sentence is out of contexst here .of infinity, the existence of a dense ordering comes true.If possible , I don't want to admit unmeasurable set .
Unmeasurable sets? A dense ordering hardly needs some measure to be
defined; I don't understand why you are taking measure into the stage.

unintuitionistic .
People are there who would reckon both as unintuitionistic.

My idea is to consider a line not a collection of points but that of0 ).
Explain.
intervals .
The collection of intervals is something else than what we in topology
consider to be the space. You probably know that if we deal with
topological aspects, the collection of interval becomes something we
call the "basis" of the topology.
Well, if you are not satisfied to view a line as the collection of
points, I must allow you to have your own opinion. But in that case,
you have got to construct a new kind of topology.
A line is, in as much as we comprehend presently, regarded as a
linearly ordered set of points; and the collection of intervals
generate a unique topology on it, called the "order topology". To
construct in your own way, I think, you shall have to review the whole
conception of order topology and their related theorems.
I recommend a paper, by van Douwen, entitled "The Horrors of topology :
a nonnormal orderable space". This will make you understand how
critical it is to deal with even our present conception of order
topology; if you pioneer a new conception, remember, you'd have to
construct a parallel, vivid, more appealing theory of this.
Marks on it is only to indicate position , not to construct it .But ordinary language does in no way impede you from using transfinite

To divide something into infinitely many parts, you need to formalize
your thought by using transfinite induction. Put your dividing machine
in mathematics, ie, in transfinite induction. Is there any so?
induction, and if you take "ordinary language" for a literal language,
I am afraid you'd fall through to put even a smidgen of your intuition
into considerably unambiguous form.
If you show it impossible by mathematical proof ,or by ordinary language , I
will try to
do so . If it is needed for yourself ,I agree ,and try to do also .
I may restate my sayings above that cheese is composed of points . hence
when it was cut at every its points, nothing is
remained .
See, what you mean by cutting is indeed a finite recursive process. You
cut nth time, then (n+1)th time. There is hardly any limit ordinal
there. But in cutting a continuous object, of whose the cardinality
surpasses d, there is a need to cut "omega'th" time; how could you
manage to do that?
About other my argument also , I want to know why some theory of mathematics
is different from our intuition .
What actually our intuition tells us is not that much clear.

This is the same as what Hero explained ."boundary" is a "point" inBut my understanding may be insuffisient .
I don't understand what you actually mean by "boundary". First
you explain this.
Yes, the end point,if my interplitation is correct .
Sorry, I couldn't have found Hero's definition. Possibly he has defined
it to be the end popint or supremum or something like that.
ofThe explanation of distance is the same as above . "length " .It's lackWe can think points in interval as a distance from a base point .
What is distance? Can you define? More than just a humour, it has a
reason to raise this question.
I want to think a line not as collection of points , but that of intervals .my ability of expression .
The reason that I asked you this question is to remind you that length
is a real number, and you are trying to characterise points, which are
real numbers, by length. This is a cyclic reasoning, isn't it?
I don't know wheather this idea goes well or not .
order to do that, you've got to toil.

We can actualy deal with only finite numbers of things .

For
No, no; certainly not. Lowenheim-Skolem's theorem deals with a deeper
concern. It tells that a first order theory based upon a countable
language, has a countable model. To comprehend the meaning of what it
means, shall need almost an entire devoted life of a mathematician.
languageit leads to a complexity, called Skolem's paradox, which has madeI don't think it paradox . We reason about infinity with countable
mathematicians all over the globe doubtful about the foundation of
mathematics. T Bays has devoted his life to the investigation of
whether it is indeed a paradox.
I shall study about this more ,and answer more correctly . As for "belongs,and with difinition based on assumption except countable case .
One of the most appealing problems that arise in this area is that, the
relation "belongs to" behaves differently within and without a

created the problem. But as far I can tell you, "a is countable" may
have two meaning:
1) { x | x in a } is countable;
2) { x | M |= ( x in a) } is countable, where M is a particular model.
May be you already know this.
So that I thougt thatThis is very controversial. You may read the thread

something that relates to this problem.

First of all, you tell me whether there is at all an infinite set.
I don't know what sort of thigs you imagined from what I said .I wonder what is the end of the universe , and where time go to .if such one exists, are we elligible to talk about its properties?You said with humor, just what I have said repeatedly so far .
Remember, in our thought we seem to be rather finite beings than
infinite ones. Is it not a paradox? If we can talk about those, I
believe we can also talk about separating points.
You may know that it is not that is what I want to say .
But it is indeed what I believe I think; for I really doubt the
existence of infinity within our intuition.
Is there at all something like what you in your mind have sketched? I
mean, is there a "universe" as you think? I mean, again, is what you
consider to be the "universe" really the Universe? What is Universe?
Can any living being comprehend it?
But for this question, my answer is that because I think , then I exist .

think; and who said, that if one thinks then one exists?

complehend the Universe .
But I am in the Universe as well as you ,and communicating with you .Probably you have read Russell's Paradox. You can not say " I have the
property p". For example, if you say " I am lying", are you lying
indeed? In view of this, you can heardly say, no matter how much urge
may you feel to utter it, "I am in the universe".
If you deny it , no communication is realised .Don't take your decision so readily!
Possibly you have heard about Saints. They use something else than mereto
intellect.
Don't ask me why I use the "mere" before intellect, for I think you
yourself should realize that in various aspects, intellect falls
through to satisfy us.
Do you say that this world doesn't exist or it is finite ? I don't dare
that wesay decidedly that it is infinite .
Is the world within your comprehension? I think you've heard about
Russell's Paradox. As while thinking, you are a part of the universe,
you can't judge the universe, can you?
In higher portions of mathematics, you shall see, gradually, that
infinite things are not at all as simple as finite ones. For example,
you might already know, that d^d = d, but it is impossible for all
nonunit finite cardinalities.
Note: the term is "cardinality", not "cardinarity".
Cardinality is not a same concept with the number . But I wonder
Regardscan
think it as expantion of
the number .
I'm afraid that I am perfectry wrong .
I am afraid, again, that everyone inside intellect is wrong. However,
it is difficult to settle what should be meant by true and what, by
wrong.
Regards and Best wishes,
Saurav

Concentrate on what I told you previously: I am afraid, again, that
everyone inside intellect is wrong. However, it is difficult to settle
what should be meant by true and what, by wrong.
