Of Known and Unknown Things
Today I saw the presentation of an ITC networking meeting in two weeks ago in Berne, and one presentation started with the following lines, which contain a deep truth:
As we know,
There are known knowns.
There are things we know we 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.
