Conversation with Thomas Jones (28 April 1934), quoted in Thomas Jones, A Diary with Letters. 1931-1950 (Oxford University Press, 1954), p. 129.
1934
„Reports that say that something hasn't happened are always interesting to me, because 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. And if one looks throughout the history of our country and other free countries, it is the latter category that tend to be the difficult ones.
The absence of evidence is not evidence of absence, or vice versa.“
Department of Defense news briefing (12 February 2002)
Variant:
Now what is the message there? The message is that there are no "knowns." There are things we know that we know. There are known unknowns. That is to say there are things that we now know we don't know. But there are also unknown unknowns. There are things we do not know we don't know. So when we do the best we can and we pull all this information together, and we then say well that's basically what we see as the situation, that is really only the known knowns and the known unknowns. And each year, we discover a few more of those unknown unknowns.
:It sounds like a riddle. It isn't a riddle. It is a very serious, important matter.
:There's another way to phrase that and that is that the absence of evidence is not evidence of absence. It is basically saying the same thing in a different way. Simply because you do not have evidence that something exists does not mean that you have evidence that it doesn't exist. And yet almost always, when we make our threat assessments, when we look at the world, we end up basing it on the first two pieces of that puzzle, rather than all three.

„Some speak of things we know, as new;
And you, of things unknown as things forgot.“

„The most difficult thing is to know what we do know, and what we do not know.“
— P. D. Ouspensky, buch Tertium Organum
Quelle: Tertium Organum (1912; 1922), Ch. I
Kontext: The most difficult thing is to know what we do know, and what we do not know.
Therefore, desiring to know anything, we shall before all else determine WHAT we accept as given, and WHAT as demanding definition and proof; that is, determine WHAT we know already, and WHAT we wish to know.
In relation to the knowledge of the world and of ourselves, the conditions would be ideal could we venture to accept nothing as given, and count all as demanding definition and proof. In other words, it would be best to assume that we know nothing, and make this our point of departure.
But unfortunately such conditions are impossible to create. Knowledge must start from some foundation, something must be recognized as known; otherwise we shall be obliged always to define one unknown by means of another.

Kontext: There is something wrong with our world, something fundamentally and basically wrong. I don't think we have to look too far to see that. I'm sure that most of you would agree with me in making that assertion. And when we stop to analyze the cause of our world's ills, many things come to mind. We begin to wonder if it is due to the fact that we don't know enough. But it can't be that. Because in terms of accumulated knowledge we know more today than men have known in any period of human history. We have the facts at our disposal. We know more about mathematics, about science, about social science, and philosophy than we've ever known in any period of the world's history. So it can't be because we don't know enough. And then we wonder if it is due to the fact that our scientific genius lags behind. That is, if we have not made enough progress scientifically. Well then, it can't be that. For our scientific progress over the past years has been amazing. Man through his scientific genius has been able to dwarf distance and place time in chains, so that today it's possible to eat breakfast in New York City and supper in London, England. Back in about 1753 it took a letter three days to go from New York City to Washington, and today you can go from here to China in less time than that. It can't be because man is stagnant in his scientific progress. Man's scientific genius has been amazing. I think we have to look much deeper than that if we are to find the real cause of man's problems and the real cause of the world's ills today. If we are to really find it I think we will have to look in the hearts and souls of men.
