The poems that follow are the exact words of the defense secretary, as taken from the official transcripts on the Defense Department Web site.
The Unknown
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.—Feb. 12, 2002, Department of Defense news briefing

What he didn’t mention, is that there are also unknown knowns! That is to say, things we don’t know we know.
