„Absence of evidence is not evidence of absence.“

—  Martin J. Rees cosmologist, astrophysicist, Astronomer Royal, Master of Trinity College, President of the Royal Society 1942

As quoted in Project Cyclops: A Design Study of a System for Detecting Extraterrestrial Intelligent Life (1971) http://ntrs.nasa.gov/archive/nasa/casi.ntrs.nasa.gov/19730010095_1973010095.pdf by Bernard M. Oliver, and John Billingham, Ch. 2 : Life in the Universe, p. 3 ; this has frequently misattributed to Carl Sagan, who quoted it in some of his presentations.

„Even if the absence of evidence for a given god were not evidence of its absence, it would still be evidence that the belief in that god is unreasonable. That's the only proposition that any atheist of any kind has to demonstrate in order to win the argument. Because anything beyond that… is just having fun.“

„In principle, it might be possible to obtain evidence of focal-attentive processing in the absence of awareness of what is being processed… in practice, however, a complete dissociation of consciousness from focal-attentive processing is difficult to achieve.“

„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.“

—  Donald Rumsfeld U.S. Secretary of Defense 1932

Department of Defense news briefing (12 February 2002)
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.

„But so long as men are not trained to withhold judgment in the absence of evidence, they will be led astray by cocksure prophets, and it is likely that their leaders will be either ignorant fanatics or dishonest charlatans. To endure uncertainty is difficult, but so are most of the other virtues.“

—  Bertrand Russell logician, one of the first analytic philosophers and political activist 1872 - 1970

1940s, Philosophy for Laymen (1946)
Kontext: The demand for certainty is one which is natural to man, but is nevertheless an intellectual vice. If you take your children for a picnic on a doubtful day, they will demand a dogmatic answer as to whether it will be fine or wet, and be disappointed in you when you cannot be sure. The same sort of assurance is demanded, in later life, of those who undertake to lead populations into the Promised Land. “Liquidate the capitalists and the survivors will enjoy eternal bliss.” “Exterminate the Jews and everyone will be virtuous.” “Kill the Croats and let the Serbs reign.” “Kill the Serbs and let the Croats reign.” These are samples of the slogans that have won wide popular acceptance in our time. Even a modicum of philosophy would make it impossible to accept such bloodthirsty nonsense. But so long as men are not trained to withhold judgment in the absence of evidence, they will be led astray by cocksure prophets, and it is likely that their leaders will be either ignorant fanatics or dishonest charlatans. To endure uncertainty is difficult, but so are most of the other virtues. For the learning of every virtue there is an appropriate discipline, and for the learning of suspended judgment the best discipline is philosophy.
But if philosophy is to serve a positive purpose, it must not teach mere skepticism, for, while the dogmatist is harmful, the skeptic is useless. Dogmatism and skepticism are both, in a sense, absolute philosophies; one is certain of knowing, the other of not knowing. What philosophy should dissipate is certainty, whether of knowledge or of ignorance.

„The absence of ideology in a work does not mean an absence of ideas; on the contrary it fertilizes them.“

—  Eugéne Ionesco Romanian playwright 1909 - 1994

"A Reply to Kenneth Tynan: The Playwright's Role" in The Observer (29 June 1958)
Kontext: Every work of art (unless it is a psuedo-intellectualist work, a work already comprised in some ideology that it merely illustrates, as with Brecht) is outside ideology, is not reducible to ideology. Ideology circumscribes without penetrating it. The absence of ideology in a work does not mean an absence of ideas; on the contrary it fertilizes them.
