I don't see how a logical theory can be based on the undefined.


Then perhaps you should learn some basic mathematical logic.

Perhaps you should learn how not to assume things.

You're right. I owe you a big apology. Just because you posted to a
mathematics group (sci.math), with a mathematical question about the
meaning of some mathematical terms of art, quoting a mathematics book
written by mathematicians, and a specific mathematician (Cantor), I
should not have assumed that you were looking for a mathematical
answer.

My deep and sincere apologies. I should have realized that it was just
a fickle twist of fate the directed your question to sci.math instead
of alt.usage.english, where it belonged.

Apology accepted. But you're wrong, it does belong here.
I was basically asking whether elements in a set need to share something in
common. That's all.
Why would you think that it would be more appropriate in alt.usage.english?
