Absence Quote by Donald Rumsfeld
“There's another way to phrase that and that is that the absence of evidence is not the evidence of absence. It is basically saying the same thing in a different way. Simply because you do not have evidence that something does exist does not mean that you have evidence that it doesn't exist.”

![“Until recent times, absence of evidence for his [Jehovah's] existence has not been sufficient to rule him out. However, we now have enough knowledge that we can identify many places where there should be evidence, but there is not. The absence of that evidence allows us to rule out the existence…” quote by Victor J.
