“We,” said Majikthise, “are Philosophers.”

“Though we may not be,” said Vroomfondel waving a warning finger at the programmers.

“Yes we are,” insisted Majikthise. “We are quite definitely here as representatives of the Amalgamated Union of Philosophers, Sages, Luminaries and Other Thinking Persons, and we want this machine off, and we want it off now!”

“What’s the problem?” said Lunkwill.

“I’ll tell you what the problem is mate,” said Majikthise, “demarcation, that’s the problem!”

“We demand,” yelled Vroomfondel, “that demarcation may or may not be the problem!”

“You just let the machines get on with the adding up,” warned Majikthise, “and we’ll take care of the eternal verities thank you very much. You want to check your legal position you do mate. Under law the Quest for Ultimate Truth is quite clearly the inalienable prerogative of your working thinkers. Any bloody machine goes and actually finds it and we’re straight out of a job aren’t we? I mean what’s the use of our sitting up half the night arguing that there may or may not be a God if this machine only goes and gives us his bleeding phone number the next morning?”

“That’s right!” shouted Vroomfondel, “we demand rigidly defined areas of doubt and uncertainty!”

Suddenly a stentorian voice boomed across the room.

“Might I make an observation at this point?” inquired Deep Thought.

“We’ll go on strike!” yelled Vroomfondel.

“That’s right!” agreed Majikthise. “You’ll have a national Philosopher’s strike on your hands!”

The hum level in the room suddenly increased as several ancillary bass driver units, mounted in sedately carved and varnished cabinet speakers around the room, cut in to give Deep Thought’s voice a little more power.

“All I wanted to say,” bellowed the computer, “is that my circuits are now irrevocably committed to calculating the answer to the Ultimate Question of Life, the Universe, and Everything—” he paused and satisfied himself that he now had everyone’s attention, before continuing more quietly, “but the programme will take me a little while to run.”

Fook glanced impatiently at his watch.

“How long?” he said.

“Seven and a half million years,” said Deep Thought.

Lunkwill and Fook blinked at each other.

“Seven and a half million years…!” they cried in chorus.

“Yes,” declaimed Deep Thought, “I said I’d have to think about it, didn’t I? And it occurs to me that running a programme like this is bound to create an enormous amount of popular publicity for the whole area of philosophy in general. Everyone’s going to have their own theories about what answer I’m eventually to come up with, and who better to capitalize on that media market than you yourself? So long as you can keep disagreeing with each other violently enough and slagging each other off in the popular press, you can keep yourself on the gravy train for life. How does that sound?”

The two philosophers gaped at him.

“Bloody hell,” said Majikthise, “now that is what I call thinking. Here Vroomfondel, why do we never think of things like that?”

“Dunno,” said Vroomfondel in an awed whisper, “think our brains must be too highly trained Majikthise.”

So saying, they turned on their heels and walked out of the door and into a lifestyle beyond their wildest dreams.

“Yes, very salutary,” said Arthur, after Slartibartfast had related the salient points of the story to him, “but I don’t understand what all this has got to do with the Earth and mice and things.”

“That is but the first half of the story Earthman,” said the old man. “If you would care to discover what happened seven and a half millions later, on the great day of the Answer, allow me to invite you to my study where you can experience the events yourself on our Sens-O-Tape records. That is unless you would care to take a quick stroll on the surface of New Earth. It’s only half completed I’m afraid—we haven’t even finished burying the artificial dinosaur skeletons in the crust yet, then we have the Tertiary and Quarternary Periods of the Cenozoic Era to lay down, and…”

“No thank you,” said Arthur, “it wouldn’t be quite the same.”

“No,” said Slartibartfast, “it won’t be,” and he turned the aircar round and headed back towards the mind-numbing wall.

Slartibartfast’s study was a total mess, like the results of an explosion in a public library. The old man frowned as they stepped in.

“Terribly unfortunate,” he said, “a diode blew in one of the life-support computers. When we tried to revive our cleaning staff we discovered they’d been dead for nearly thirty thousand years. Who’s going to clear away the bodies, that’s what I want to know. Look why don’t you sit yourself down over there and let me plug you in?”

He gestured Arthur towards a chair which looked as if it had been made out of the rib cage of a stegosaurus.

“It was made out of the rib cage of a stegosaurus,” explained the old man as he pottered about fishing bits of wire out from under tottering piles of paper and drawing instruments. “Here,” he said, “hold these,” and passed a couple of stripped wire end to Arthur.

The instant he took hold of them a bird flew straight through him.

He was suspended in mid-air and totally invisible to himself. Beneath him was a pretty treelined city square, and all around it as far as the eye could see were white concrete buildings of airy spacious design but somewhat the worse for wear—many were cracked and stained with rain. Today however the sun was shining, a fresh breeze danced lightly through the trees, and the odd sensation that all the buildings were quietly humming was probably caused by the fact that the square and all the streets around it were thronged with cheerful excited people. Somewhere a band was playing, brightly coloured flags were fluttering in the breeze and the spirit of carnival was in the air.

Arthur felt extraordinarily lonely stuck up in the air above it all without so much as a body to his name, but before he had time to reflect on this a voice rang out across the square and called for everyone’s attention.

A man standing on a brightly dressed dais before the building which clearly dominated the square was addressing the crowd over a Tannoy.

“O people waiting in the Shadow of Deep Thought!” he cried out. “Honoured Descendants of Vroomfondel and Majikthise, the Greatest and Most Truly Interesting Pundits the Universe has ever known… The Time of Waiting is over!”

Wild cheers broke out amongst the crowd. Flags, streamers and wolf whistles sailed through the air. The narrower streets looked rather like centipedes rolled over on their backs and frantically waving their legs in the air.

“Seven and a half million years our race has waited for this Great and Hopefully Enlightening Day!” cried the cheer leader. “The Day of the Answer!”

Hurrahs burst from the ecstatic crowd.

“Never again,” cried the man, “never again will we wake up in the morning and think Who am I? What is my purpose in life? Does it really, cosmically speaking, matter if I don’t get up and go to work? For today we will finally learn once and for all the plain and simple answer to all these nagging little problems of Life, the Universe and Everything!”

As the crowd erupted once again, Arthur found himself gliding through the air and down towards one of the large stately windows on the first floor of the building behind the dais from which the speaker was addressing the crowd.

He experienced a moment’s panic as he sailed straight through towards the window, which passed when a second or so later he found he had gone right through the solid glass without apparently touching it.
