to all newbies/strangers whom it may concern:
by jumping into long threads and replying without providing some context (via 'quote', cut/paste, etc.), you tend to confuse us poor folk who read this stuff in flat mode. thank you for your kind attention.

Hi Faldage
You said:
From a logical point of view what the barber does to men who do not shave themselves has no bearing on what he does to those who do shave themselves.
This is absolutely correct, and none of us pointed it out. Yet I remember quite clearly a genuinely logical paradox in the barber scenario, and realised that Emanuela statment of the problem left unstates something that we all considered implicit in the case:
The barber not only shaves all who don't shave themselves, but also only shaves those who do not shave themselves. It's the only that makes the difference because (apart from the 'riddle' answer of the barber being a woman, or someone not needing shaving) the barber is now constrained not to shave himself... and therefore to do so... and therefore to refrain... and so on
cheer

In reply to:
All rules have exceptions, including this one.
OK, please supply an example of an exception to the above stated rule.
Itself.
Or
Rule 1: The umpire is always right.
Rule 2: When the umpire is wrong, see Rule 1.

Thanks shanks for "The barber not only shaves all who don't shave themselves, but also only shaves those who do not shave themselves."
I agree that the inclusion of the word "only" makes a big difference, but, in a larger sense, I must protest that a paradox is more a measure of our ignorance or sloppy thinking than it is a measure of the irrationality of a situation.

What about Godel's paradox, that leads to his incompleteness theorem. Nothing sloppy about his thinking. Nothing straightforward about Incompleteness.

Another great perk for Cadillac owners, I assume.
But my real question is:
What do you have when you have the barber running around screaming, "Shave yourselves! Shave yourselves!"?

In reply to:

I have on order at my local bookstore a copy of a book that is supposed to be an exceptionally clear exposition of Godel's Incompleteness Theorem, Godel's Proof by Ernest Nagel. Perhaps after I have read it we can start a whole new thread. My present understanding of the incompleteness theorem does not interfere with my present beliefs on paradoxes.

Now would that be malfeazance or misfeazance?
