…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.

Donald Rumsfeld

Rumsfeld got a lot of criticism from people who gave no thought to what he actually said and believed he was spouting nonsense, but having studied Knowledge Management a few years back he has actually listed 3 of 4 different categories of knowledge, so whilst I didn’t share his political agenda I couldn’t argue with what he said but for one thing.  The fourth, unmentioned, category is that of the unknown known, which also sounds nonsensical, but refers to those things that we are aware of but refuse to believe or acknowledge because they don’t fit with our view of the world.  How ironic that he shouldn’t have known that!

This was part of a Biennale art installation in the shop windows of Via Garibaldi… and a knowing selfie!
