That is to say



There are 

known knowns. 

These are things 

we know 
that we know. 

There are 

known unknowns. 

That is to say 

there are things 

that we know 
we don't know. 

But 

there are also 

unknown unknowns.

These are things 

we don't know  
we don't know. 


 - Donald Rumsfeld

  1. What about the things we don't know we know? Or the things we think we know but probably don't? Or the things we've forgotten that we know? Or the things we would know if only we had the time to get round to knowing them?

  2. I don't think he mentioned all them Jim. He was trying to find reasons to return Iraq to the stone age.
