The figurative line is considerably realer than the real line, Brian.

Not sure. Still working out the meaning.

Don't worry about Brian, Tony. He's just confused.

Tony, I'm going to strip as much as seems unessential.

No but that only applies to linear approximations for pi, Tony. It has
nothing to do with the actual value of pi which lies off to the side
of any real number line. Imagine if you will the linear order you
speak of superimposed on a real number plane instead of a straight
line (which isn't even possible either). Then pi has to lie off to one
side of the straight line. So the metric for the straight line becomes
a non linear variable instead of linear. Thus the fact that the value
of pi lies between 3 and 4 doesn't show any value for pi and never
will. All you wind uyp with is a linear metric which approximates pi
which doesn't provide us with any real number line running along the
lines of 1, 2, e, 3, pi. So the real number line metric is variable.

Well points don't occupy any space at all, Tony. Intersection ends in
points but subdivision never ends in points. That's the difference
between intersection and differentiation. Although not a natural zero
certainly exists but the question is how it's used. Zero used as a
limit is approachable but not reachable. Same with infinity. Zero used
as a divisor is undefinable. Maybe you're trying to combine arithmetic
and infinitesimal calculus operations in ways that are incompatible?

Well the question I have then is whether such a set can be infinite or
contain only finites without limit?

And I would agree. But the elements in the set never become non
finite. So "infinite" in that sense only means successive finite
elements "without limit". But there are different kinds of infinities
in this sense which unfortunately only make sense in relation to one
another in terms of the infinitesimal calculus used to calculate
various forms and relate them to one another. L'Hospital's rule. And
once again it looks like a lot of mathematkers are inappropriately
trying to transmogrify arithmetic into infinitesimal calculus.
