That the set is different from its
elements is precisely why logical
construction by classes takes the
form of a class hierarchy.

This is why the rational numbers
used to construct Dedekind cuts are
not the same as the rational numbers
represented by Dedekind cuts.

Because you do not bother to understand
these things, you confuse yourself and
blame it on Cantor.

But, Cantor explained himself clearly
on these matters. Thus the fault lies
with you.

Does anyone have a crayon to play with?
