“There is a rational explanation for everything, regardless of whether that explanation is known.”

“Fisher just stood there lost in thought, without saying anything. There is always a rational explanation for everything in this world - whether it's the true one or not. Maybe it is better so. ("I'm Dangerous Tonight")”

“I believe there is an explanation for everything - although we shall never know the explanation for everything. Not everything in this world can be understood by us, nor should it be. It is not necessary.”

“There isnt always an explanation for everything.”

“Dad reckoned there was a rational explanation for everything, even things that made no sense at all. UFOs, ghosts, God - they're just the names people came up with for stuff they haven't worked out yet.”

“Everyone always has to have the rational, scientific explanation for something, even if it's so obviously wrong you could scream.”
