I sometimes consider how Bertrand Russell, the
famous mathematician and philosopher, fretted away a whole year, from 1903 to
1904, contemplating this one thought:
A
man of Seville is shaved by the barber of Seville if and only if the man does
not shave himself. Does the Barber shave
himself?
I find difficulty in imagining an intelligent man
contemplating such a thought for an entire year and more difficult to consider
that this paradox seemingly blew out of the water all mathematical logic. But here is the paradox: If the barber shaved
himself—he didn't shave himself. If the
barber didn't shave himself—he did shave himself.
Think about that for a moment. Read the italicized sentence a few
times. Think a bit more. As I read about this philosophical and
mathematical dilemma and tried to solve the problem myself, I realized that Mr.
Russell suffered from a lack of options.
I reconfigured the question posed by Russell and added a few options.
What if a woman has a mustache to shave? How does that fit?
What if the barber actually grows a beard that he
never even trims?
What if—by genetic defect or as result of auto
immune disease—a man has no body hair, and never shaves?
Is the barber of Seville technically a barber as he
strolls down the street? When he
eats? Does his shaving count if he shaves himself at home
instead of at his shop?
How much does the barber of Seville charge for a
shave?
Should you tip him?
What if you had a trench to dig...would you hire a
philosopher or the barber of Seville?
What were we talking about?

Note: I may have posted a
slightly different version of this a few years ago on this post. Also, I shave myself.
