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?
