A Quote by Donald Rumsfeld

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.

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. There are things we don't know we don't know.

Donald Rumsfeld

When you start talking about the known knowns and the unknown unknowns, you're thrown into a crazy meta-level discussion. Do I know what I know, do I know what I don't know, do I know what I don't know I don't know. It becomes a strange, Lewis Carroll - like nursery rhyme.

Errol Morris

There are known knowns and known unknowns, but what we should be worried about most is the unknown unknowns.

Gary Marcus

The word "knowledge" itself, we like to break it down into two different words, "know" and "ledge." You've got to know the ledge. Know the limitation of things. Know where they go, know where they start from. We say knowledge is the basic foundation of the universe. But everything is first based on something being known. Then, when it's known, then it can be manifested.

Rza

The transition from unknown to known-in-publishing has been empowering but also challenging. It's an honor to know that people actually want to know what I think about certain issues, but I also have to be careful about what I say or, rather, how I say it. The Internet is forever, y'all.

Angie Thomas

As known unknowns become known; unknown unknowns proliferate; the larger the island of knowledge, the longer the shoreline of wonder.

Huston Smith

I know deep hurt. But I also know deep hope. Sometimes God's power is shown as much in preventing things as it is in making them happen. We may never know why. But we can always know and trust the Who.

Yes, our greatness as a nation has depended on individual initiative, on a belief in the free market. But it has also depended on our sense of mutual regard for each other, of mutual responsibility. The idea that everybody has a stake in the country, that we're all in it together and everybody's got a shot at opportunity. Americans know this. We know that government can't solve all our problems - and we don't want it to. But we also know that there are some things we can't do on our own. We know that there are some things we do better together.

Barack Obama

I know I mispronounce things constantly, because maybe I read more than I talk, but I don't know the proper way to say a lot of things, even though I know what they are. But then I know I look like a moron.

Amy Heckerling

Words let us say the things we want to say and also things we would be better off not having said. They let us know the things we need to know, and also things we wish we didn't.

Steven Pinker

The terms which, in his inmost heart, each man knows. As I know mine. As all know. For that is the truth of it — that we all know, God, that we know, that we know, we know, we know.

Saul Bellow

I know my limitations. I know I'm not perfect. I know what I know, but more importantly, I know what I don't know. When I don't know something, I surround myself with people I can trust to teach me.

Brock Lesnar

I do not need to know all things. I remind myself that it is sufficient that I know what I know and know that without believing that I will always know what I know or that what I know will always be true.

Maya Angelou

Every time I think I’m getting smarter I realize that I’ve just done something stupid. Dad says there are three kinds of people in the world: those who don’t know, and don’t know they don’t know; those who don’t know and do know they don’t know; and those who know and know how much they still don’t know. Heavy stuff, I know. I think I’ve finally graduated from the don’t-knows that don’t know to the don’t-knows that do.
