“[Modern scientific] theories can necessarily never be more than hypothetical, since their starting-point is wholly empirical, for facts in themselves are always susceptible of diverse explanations and so never have been and never will be able to guarantee the truth of any theory.”

“I stopped trying to figure it out a long time ago. I'm never going to figure it out,any more than a normal person will figure out his or her own existence. After a while, you have to be at peace with the fact that you simply are. There is no way to know why. You can have theories, but there will never be proof.”

“It is sometimes said that we should never believe a scientific theory until it is verified by experiment. But a famous astronomer has also stated that we should never believe an observation until it is confirmed by a theory.”

“I have a theory that the truth is never told during the nine-to-five hours.”

“It is a scientifically proven fact that all scientifically proven facts have originated from original and thereby unproven theories.”

“The theory must not contradict empirical facts,”
