The Unknown —Feb. 12, 2002, Department of Defense news briefing Why, you may wonder, a I opening with a 14-year-old Donald Rumsfeld quote that was shaped into a poem? Because it gives me a good opening to talk about the things I want to talk about.
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.
Unknown Unknowns
