"Unknown Unknowns...:

"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 do not know."

"Simply because you do not have evidence that something
 exists does not mean that you have evidence that it doesn't exist."

"Learn to say 'I don't know.' If used when appropriate, it will be often."
- Donald Rumsfeld
