As we knowBy Donald Rumsfeld, 2003
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.
Parece-vos confuso?! =)
Não...não andei a fumar as mesmas coisas que tu V.
