But to understand how and why, we should consider what is possibly the most famous quotation of all time on the subject of brevity, which is from William Shakespeare's Hamlet, and the tragicomic figure of Polonius.
"To thine own self be true," says the fraud.
This line caps his advice to his son on how to make his way in the world, and on its face it seems pretty solid.
So he's sending a spy to make sure his son is not ruining his reputation, by ruining it for him.
"Brevity is the soul of wit" is part of a larger quotation by Polonius that does not appear as part of the aforementioned scene, which originated multiple quotations.
Reader, he is not.
Polonius is not brief, but he is also witless.
And how am I brief?
Why, as brevity is the soul of wit, and I am witty, I must be brief deep down in my soul.
Where no one will ever see it.
