I’ll always remember him saying:
“There are things you know,
Things you know you don’t know,
Things you don’t know you don’t know.”
Rip Mr. R.

Here’s what he said:

“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”

The press had a field day making fun of that, not knowing that it was their ignorance that made it funny. I am no rocket surgeon, but I knew what he meant and didn’t find it outrageous at all.

It is never possible to know what you don’t know you don’t know.
