“You know,” said Arthur thoughtfully, “all this explains a lot of things. All through my life I’ve had this strange unaccountable feeling that something was going on in the world, something big, even sinister, and no one would tell me what it was.”

“No,” said the old man, “that’s just perfectly normal paranoia. Everyone in the Universe has that.”

“Everyone?” said Arthur. “Well, if everyone has that perhaps it means something! Perhaps somewhere outside the Universe we know …”

“Maybe. Who cares?” said Slartibartfast before Arthur got too excited. “Perhaps I’m old and tired,” he continued, “but I always think that the chances of finding out what really is going on are so absurdly remote that the only thing to do is to say hang the sense of it and just keep yourself occupied. Look at me: I design coastlines. I got an award for Norway….Science has achieved some wonderful things of course, but I’d far rather be happy than right any day.”

“And are you?”

“No. That’s where it all falls down of course.”
