Cue music: A man begins to sing:
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.

"Nope, that's Phil Kline's setting of a text by Donald Rumsfeld." Maybe it wasn't Mallarmé, but I found it affecting. DeVore was right—it was great music.
