Stumble upon this web site today and there is a collection of “poetry”of the US ex-DOD chief – D. H. Rumsfeld. It’s really amazing that what one can speak in front of the press … and I remember this lucidly …
“As we know, there are known knowns.
There are things we know we know.
We also know there are known unknowns.
That is to say we know there are some things we do not know.
But there are also unknown unknowns.
The ones we don’t know we don’t know.”
But somehow Mr. Rumsfeld missed one more thing:
“There are unknown knowns, the ones we don’t know we know …” 😎
