Known Unknowns
The lyrics to this brief folk song sung by Steven are based on an infamous statement U.S. Secretary of Defense Donald Rumsfeld made during a Defense Department briefing on February 12, 2002.
And as we know
There are known knowns
There are things we know we know
(Things that we know that we know, all right?)
We also know
There are known unknowns
That is to say there are some things we know we do not know
(There are some things that we know that we do not know)
There are also unknown unknowns
The ones we don't know we don't know
We don't know
We don't know
We don't know
There are known knowns
There are things we know we know
(Things that we know that we know, all right?)
There are known unknowns
That is to say there are some things we know we do not know
(There are some things that we know that we do not know)
The ones we don't know we don't know
We don't know
We don't know
