“There is no point in using the word 'impossible' to describe something that has clearly happened.”

“Goosnargh," said Ford Prefect, which was a special Betelgeusian word he used when he knew he should say something but didn't know what it should be.”

“Anything that happens, happens.Anything that, in happening, causes something else to happen, causes something else to happen.Anything that, in happening, causes itself to happen again, happens again.It doesn’t necessarily do it in chronological order, though.”

“The impossible often has a kind of integrity to it which the merely improbable lacks.”

“There is a theory which states that if ever anyone discovers exactly what the Universe is for and why it is here, it will instantly disappear and be replaced by something even more bizarre and inexplicable. There is another theory which states that this has already happened.”

“There was a point to this story, but it has temporarily escaped the chronicler's mind.”

“What was the Sherlock Holmes principle? ‘Once you have discounted the impossible, then whatever remains, however improbable, must be the truth.’ ” “I reject that entirely,” said Dirk sharply. “The impossible often has a kind of integrity to it which the merely improbably lacks. How often have you been presented with an apparently rational explanation of something that works in all respects other than one, which is that it is hopelessly improbable?...The first idea merely supposes that there is something we don’t know about, and...there are enough of those. The second, however, runs contrary to something fundamental and human which we do know about. We should therefore be very suspicious of it and all its specious rationality.”
