Pete, that's certainly clever, but logic is logic, and sometimes saying
one thing definitely implies another thing without any doubt whatsoever.
In other words, if the barber does not have a beard then he is one of those
people who does not shave himself and since he shaves all those who do not
shave themself it's still a contradiction because in short form we would
still be saying "the barber shaves himself but he does not shave himself".

I've also heard that the barbers beard caught on fire (hee hee) but
then again that means he doesnt shave himself and so he shaves himself
and the paradox shows up again anyway (with laughts i guess too).
Maybe this is what Don was alluding to in his post which i read already.

A little more (short) interesting read on this paradox can be found here:

Looking at things like this definitely helps a persons programming
technique in any language because programming in it's best form is
a perfectly logical endeavor, similar to chess.

I would like to see a program that can deal with things like this
written in Euphoria, but it would take a huge amount of effort and
research im sure.  Automated reasoning deals with this kind of thing,
and in this case would prove that there was a paradox; a set of 
statements that have no solution.  Something to do this written in
Euphoria would be really great!  I think it would have to be able to
interpret the human language however to be totally automatic.
Anyone up to the challenge?



Take care,
Al
