Private: Things we know we know

From the London Telegraph:

In Pieces of Intelligence: the Existential Poetry of Donald H Rumsfeld (Simon & Schuster, £8.99), the humorist Hart Seely has taken the American Defence Secretary’s words and set them as verse. This first collection is culled predominantly from Rumsfeld’s public readings – or “briefings”, as he styles them – but it includes material from the more combative, slam-style “interviews” at which he refined his craft. The opening poem, “The Unknown”, can be read as a sort of manifesto. It merits quoting in full:

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.
