Our Final Hour: A Scientist's Warning (2003) <!-- | date = 2003-03-18
Context: Once the threshold is crossed when there is a self-sustaining level of life in space, then life's long-range future will be secure irrespective of any of the risks on Earth (with the single exception of the catastrophic destruction of space itself). Will this happen before our technical civilisation disintegrates, leaving this as a might-have-been? Will the self-sustaining space communities be established before a catastrophe sets back the prospect of any such enterprise, perhaps foreclosing it for ever? We live at what could be a defining moment for the cosmos, not just for our Earth.

“No one can say which approach is the right one — so no one can say how close we are to a solution.”

“Absence of evidence is not evidence of absence.”
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.
