The Senior Common Room Discusses Intelligence (Again) Or: Before We Invent Superintelligence

The Senior Common Room at St Anselm's had acquired an unusual silence.

This generally indicated that someone had used a familiar word without defining it.

Professor Quillibrace closed the newspaper.

"I see," he observed, "that we are once again being promised superintelligence."

Mr Blottisham looked interested.

"Excellent."

"Is it?"

"I should think so."

"Why?"

"Well..."

Blottisham hesitated.

"...because it sounds better than ordinary intelligence."

---

Miss Stray smiled.

"What do they mean by intelligence?"

Blottisham looked surprised.

"Surely everyone knows."

Professor Quillibrace raised an eyebrow.

"My dear Blottisham..."

he said,

"...those are among the most dangerous words in philosophy."

---

Blottisham frowned.

"Very well."

He thought for a moment.

"Intelligence is..."

Another pause.

"...being clever."

"I see."

"And cleverness is..."

"...intelligence."

Professor Quillibrace nodded.

"We appear to have made satisfactory progress."

---

Miss Stray laughed.

"Perhaps we should begin somewhere simpler."

"Please."

"What does intelligence actually help us to do?"

Blottisham looked relieved.

"Oh, that's easy."

He counted on his fingers.

"Crosswords."

"Indeed."

"Chess."

"Sometimes."

"Mathematics."

"Often."

"Pub quizzes."

"Regrettably."

---

"And?"

asked Miss Stray.

Blottisham stopped counting.

"That's all I can think of."

---

Professor Quillibrace folded the newspaper.

"An interesting list."

"Thank you."

"It consists almost entirely of puzzles."

"So?"

"So is life principally composed of puzzles?"

---

Blottisham looked puzzled.

"I hadn't thought about it."

"No."

---

Miss Stray looked out across the quadrangle.

"What did you do yesterday?"

Blottisham blinked.

"I beg your pardon?"

"What occupied your day?"

"Oh."

He considered.

"I made breakfast."

"Very good."

"I answered some emails."

"Excellent."

"I watered the tomatoes."

"Commendable."

"I visited my sister."

"Splendid."

"I watched the football."

"Worthy."

"I made shepherd's pie."

"A classic."

---

Professor Quillibrace waited.

"And?"

"That's about it."

---

Quillibrace looked thoughtful.

"Which of those activities required exceptional intelligence?"

Blottisham considered the matter carefully.

"The shepherd's pie."

"No."

"The tomatoes?"

"No."

"The emails?"

"No."

"The football?"

"No."

"My sister?"

"I sincerely hope not."

---

Miss Stray smiled.

"So most of your day was not limited by intelligence."

"No..."

said Blottisham slowly.

"It was limited by time."

---

Professor Quillibrace nodded.

"Precisely."

---

Another silence settled over the room.

Eventually Blottisham spoke.

"So if someone became twice as intelligent..."

"Yes?"

"...they wouldn't necessarily live twice as well."

"No."

"Or twice as happily."

"No."

"Or twice as quickly."

"No."

"Or make twice as much shepherd's pie."

"I suspect not."

---

Miss Stray stirred her tea.

"Perhaps we imagine intelligence as though it were like horsepower."

Professor Quillibrace looked interested.

"Go on."

"If someone tells us an engine has twice the horsepower..."

"Yes?"

"...we immediately imagine it doing more work."

"Naturally."

"But people are not engines."

---

"No," said Quillibrace.

"They are constrained by many things besides intelligence."

---

"Such as?"

asked Blottisham.

"Energy."

"Certainly."

"Time."

"Indeed."

"Health."

"Quite."

"Opportunity."

"Obviously."

"Laziness."

"Frequently."

---

"And affection."

Miss Stray added quietly.

Both men looked at her.

"There are many things," she said, "that we do well, not because we are especially intelligent, but because we care."

Professor Quillibrace said nothing.

After a moment he inclined his head.

---

Blottisham looked thoughtful.

"So perhaps intelligence isn't the master key."

"No."

"It's just one key."

"A useful one."

"But not the only one."

---

Professor Quillibrace reopened the newspaper.

"I should therefore be interested to know what people mean when they promise us superintelligence."

Blottisham smiled.

"Someone very, very clever?"

"No."

"What then?"

"I haven't the faintest idea."

---

Miss Stray laughed.

"So before discussing superintelligence..."

"...we should first discover what ordinary intelligence actually is."

Professor Quillibrace smiled.

"Now that..."

he said,

"...strikes me as an intelligent place to begin."

---

The college clock struck five.

Mr Blottisham stood.

"I've just realised something."

"What?"

"I spend very little of my life actually needing to be clever."

Professor Quillibrace collected his books.

"My dear Blottisham..."

he said,

"...that may be the wisest observation you have made this term."

X: The Adventure Continues

The Senior Common Room was unusually quiet.

Outside, the last light of the afternoon settled gently across the college gardens.

Mr Blottisham looked around the room with an expression of mild dissatisfaction.

"I believe we've reached the end."

Professor Quillibrace glanced up.

"Have we?"

"I don't appear to have any more questions."

Miss Stray smiled.

"That would be a first."

"I mean about intelligence."

"I see."

"I think we've finally answered it."

Professor Quillibrace regarded him thoughtfully.

"How unfortunate."

Blottisham frowned.

"Unfortunate?"

"I had rather hoped we hadn't."

A comfortable silence followed.

The fire shifted quietly.

Eventually Miss Stray spoke.

"We have travelled quite a long way."

"We have?"

"We began by asking whether machines could think."

"Oh."

"I'd almost forgotten."

"So had I," said Professor Quillibrace.

Blottisham looked puzzled.

"How did we end up here?"

Quillibrace smiled.

"By refusing to remain where we started."

Miss Stray nodded.

"We discovered conversations."

"And forests."

"Quartets."

"Horizons."

"Questions."

"Emergence."

"Relationships."

Blottisham counted them silently upon his fingers.

"It does seem rather an indirect route."

"The interesting ones usually are."

Another silence settled over the room.

Outside, several students crossed the quadrangle, still arguing cheerfully about something none of them seemed especially determined to win.

Miss Stray watched them disappear beneath the archway.

"I've been wondering."

"What about?" asked Blottisham.

"Whether every age imagines intelligence differently."

Professor Quillibrace looked interested.

"Go on."

"The ancient world admired wisdom."

"Indeed."

"The Enlightenment celebrated reason."

"Quite."

"The industrial age loved efficiency."

"Undoubtedly."

"And we..."

She paused.

"...seem to have become fascinated by information."

Blottisham nodded.

"That sounds about right."

"But perhaps..."

She looked towards Quillibrace.

"...we're beginning to notice something else."

Professor Quillibrace folded his hands.

"What do you suppose that might be?"

"Relationships."

The word lingered quietly between them.

Blottisham looked thoughtful.

"So intelligence..."

"...yes?"

"...isn't merely something people possess."

"No."

"It's something they participate in."

Professor Quillibrace smiled.

"I believe you've arrived."

"At the answer?"

"No."

"Then where?"

"At a rather more interesting beginning."

The room fell comfortably silent again.

After a while Blottisham asked,

"If that's true..."

"...yes?"

"...what changes?"

Miss Stray answered first.

"Education."

"In what way?"

"We stop imagining classrooms as places where knowledge is delivered."

"And instead?"

"They become places where understanding is cultivated."

Professor Quillibrace nodded.

"Quite."

"And universities?"

"They become communities of inquiry rather than collections of experts."

"Research?"

"The design of conversations."

"Leadership?"

"The stewardship of relationships."

Blottisham laughed softly.

"Everything seems to have become conversations."

Professor Quillibrace looked amused.

"Not everything."

"What have we forgotten?"

"The quality of the conversations."

Another pause.

Outside, the chapel bell marked the hour.

Its familiar sound seemed somehow larger than usual.

Miss Stray looked towards the window.

"I've also been thinking about disagreement."

Blottisham looked suspicious.

"Must we?"

"I think so."

"I've only just become comfortable with conversations."

"Precisely."

She smiled.

"A good conversation requires difference."

"So we've established."

"But difference alone isn't enough."

"No?"

"It also requires trust."

Professor Quillibrace inclined his head.

"And generosity."

"And curiosity."

"And the willingness to be changed."

Blottisham stared thoughtfully into the fire.

"So disagreement isn't the danger."

"No."

"What is?"

"When people stop listening."

No one replied immediately.

The silence itself seemed to acknowledge the point.

Eventually Blottisham spoke again.

"So these conversational systems..."

"...yes?"

"...aren't really the centre of the story."

Professor Quillibrace looked quietly pleased.

"I don't believe they are."

"They're simply..."

He searched for the right phrase.

"...the newest participants."

Miss Stray smiled.

"And perhaps the newest mirror."

"In what sense?"

"They've helped us notice something humanity has been doing all along."

Professor Quillibrace looked around the room.

"The phenomenon was never entirely new."

"No."

"The vocabulary was."

Blottisham nodded.

"Relational intelligence."

"Quite."

He looked towards the books lining the walls.

"I used to imagine all these books contained finished thoughts."

"And now?"

"I rather suspect they're invitations."

Professor Quillibrace's expression brightened almost imperceptibly.

"A generous description."

Another silence settled over the room.

The daylight was beginning to fade.

The familiar furniture acquired that gentle indistinctness peculiar to old buildings at evening.

Miss Stray closed her notebook.

"I've been wondering one last thing."

"What is it?"

"Do you think we'll ever finish understanding intelligence?"

Professor Quillibrace considered the question for a long time.

"No."

"Why not?"

"Because understanding grows."

"So?"

"So every genuine insight enlarges the landscape within which the next insight becomes possible."

Blottisham smiled.

"The horizon again."

"The horizon again."

For a while no one spoke.

The quiet no longer felt like the end of a conversation.

It felt like the beginning of another.

At length Professor Quillibrace stood and walked to the window.

Beyond the college walls, the first evening lights were beginning to appear across the town.

Students hurried between lectures.

Friends argued amiably beneath umbrellas.

A lecturer paused to continue an animated discussion with two undergraduates.

The library windows glowed warmly.

Somewhere, faintly, a string quartet had begun rehearsing once more.

Professor Quillibrace watched the scene for several moments before speaking.

"It is an odd thing."

"What is?" asked Blottisham.

"We spend much of our lives looking for intelligence."

"We do."

"In books."

"Certainly."

"In laboratories."

"Yes."

"In schools."

"Quite."

"In ourselves."

"Naturally."

He smiled very gently.

"And all the while..."

Neither of the others interrupted.

"...it has been quietly happening between us."

No one answered.

There was nothing to add.

The room itself seemed content to preserve the silence.

Outside, the quartet continued playing.

The students continued arguing.

The lights continued appearing one by one across the town.

The conversations did not end.

They simply moved beyond the windows, carrying the endless adventure of thinking onward into the evening.

IX: Giving It a Name

The fire burned quietly.

No one appeared in any particular hurry to begin.

Mr Blottisham eventually broke the silence.

"I've noticed something."

Professor Quillibrace looked up.

"Congratulations."

"We've been discussing the same subject for weeks."

"So it would appear."

"But we keep describing it differently."

Miss Stray closed the notebook she had not been writing in.

"How so?"

"First it was conversations."

"Yes."

"Then forests."

"Quite."

"Then chamber music."

"Indeed."

"Then questions."

"And horizons."

"And exploration."

Blottisham sighed.

"We've accumulated rather a large collection of metaphors."

Professor Quillibrace smiled.

"A healthy sign."

"Is it?"

"It usually indicates one is approaching something difficult."

"But shouldn't we have a proper name by now?"

Quillibrace removed his spectacles.

"I've been wondering the same thing."

Miss Stray looked at him with interest.

"You have?"

"For some time."

Another silence settled over the room.

Outside, rain had begun again with the gentle persistence peculiar to old university towns.

Blottisham tapped the arm of his chair.

"So what exactly have we been talking about?"

Professor Quillibrace answered carefully.

"We have repeatedly encountered situations in which thinking appears to occur..."

He paused.

"...not entirely within individuals..."

"...yes?"

"...but through the relationships between them."

Blottisham nodded slowly.

"The conversations."

"The quartets."

"The forests."

"The scientists."

"The writers."

"The teachers."

"The conversational systems."

"Exactly."

Miss Stray looked thoughtful.

"None of those examples quite fitted the old picture."

"No."

"But they all resembled one another."

"Very much so."

Blottisham frowned.

"So we've been describing one phenomenon through many illustrations."

Professor Quillibrace inclined his head.

"I believe we have."

"And we've never named it."

"No."

"Why not?"

Quillibrace smiled.

"Naming things prematurely is occasionally dangerous."

Miss Stray laughed.

"You wanted to be sure the phenomenon was real before baptising it."

"A sensible precaution."

Blottisham considered this.

"I've always thought names merely labelled things."

"Sometimes."

"But sometimes?"

"Sometimes they allow us to notice what was already present."

The room became unusually still.

Miss Stray spoke almost tentatively.

"I've been thinking about ecosystems again."

Blottisham smiled.

"I wondered how long it would take."

"Not forests this time."

"No?"

"Constellations."

Professor Quillibrace looked interested.

"Go on."

"The stars were always there."

"Certainly."

"The name doesn't create the constellation."

"No."

"But once someone traces the pattern..."

"...yes?"

"...you can never quite stop seeing it."

Quillibrace nodded slowly.

"A remarkably apt comparison."

Blottisham looked from one to the other.

"So what pattern have we been tracing?"

No one answered immediately.

The silence seemed to be waiting for something.

Eventually Professor Quillibrace spoke.

"I wonder whether..."

He hesitated.

"...the phrase might be..."

Miss Stray looked up.

"...relational intelligence?"

The words settled into the room almost gently.

Blottisham repeated them.

"Relational intelligence."

No one appeared inclined to improve upon them.

After a while he asked,

"What exactly does that mean?"

Professor Quillibrace considered the question carefully.

"It does not mean that relationships are minds."

"No."

"Nor that conversations possess consciousness."

"Certainly not."

"Nor merely that people cooperate."

"We've always done that."

"Exactly."

"So what is new?"

Miss Stray answered this time.

"It is the possibility that relationships sometimes create ways of thinking unavailable to the participants considered separately."

Blottisham sat quietly.

"So..."

He looked around the room.

"...not intelligence inside relationships..."

"...yes?"

"...but intelligence becoming relational."

Professor Quillibrace smiled.

"A distinction worth preserving."

Outside, the rain intensified briefly against the windows before softening again.

Blottisham broke the silence.

"If that's true..."

"...yes?"

"...then we've been asking rather different questions."

"In what sense?"

"We stopped asking who was cleverest."

"We did."

"We stopped worrying about ownership."

"Indeed."

"We became interested in..."

He searched for the phrase.

"...the quality of the relationship."

Miss Stray nodded.

"The relationship becomes the place where new possibilities appear."

Another thoughtful silence.

Eventually Quillibrace spoke again.

"I suspect this changes rather a great deal."

"Education?"

"Certainly."

"Research?"

"Undoubtedly."

"Leadership?"

"I believe so."

"And these conversational systems?"

Professor Quillibrace looked thoughtfully towards the shelves of books surrounding them.

"They become less interesting as competitors..."

"...and more interesting as participants."

Blottisham smiled.

"I rather prefer that."

"So do I."

The rain had almost stopped.

A pale shaft of late-afternoon sunlight found its way through the window and rested across the table between them.

Miss Stray watched it for a moment.

"It's curious."

"What is?"

"The name feels new."

"It is."

"But the experience doesn't."

Professor Quillibrace nodded.

"No."

"We've all known conversations that somehow became cleverer than any of the people having them."

"We have."

"We've all belonged to collaborations that produced ideas no one could honestly claim."

"Indeed."

"We've all watched students discover questions we never intended to teach."

"Quite."

"So the phenomenon has always been here."

Professor Quillibrace looked around the room.

At the books that had prompted so many conversations.

At the notebooks filled with half-finished thoughts.

At Miss Stray's sketches.

At Mr Blottisham's ever-growing collection of questions.

At the familiar chairs that had quietly hosted all of them.

"Perhaps," he said softly, "we have spent the past several weeks doing little else."

No one replied.

There was nothing left that required saying.

For a while they simply sat together in companionable silence.

The room itself seemed oddly full.

Not with certainty.

Nor with conclusions.

But with relationships that had gradually become capable of carrying thought farther than any of them had first imagined.

Outside, the rain clouds were beginning to part.

The college gardens looked exactly as they always had.

Only now, somehow, they seemed connected in ways that had previously gone unnoticed.

VIII: What Is Intelligence For?

Mr Blottisham arrived looking unusually satisfied.

"I believe," he announced, "that I've finally understood intelligence."

Professor Quillibrace glanced up from his newspaper.

"Congratulations."

"It solves problems."

"I see."

"That's what intelligence is for."

Miss Stray looked over the rim of her teacup.

"Only that?"

Blottisham smiled confidently.

"What else could it possibly be for?"

Professor Quillibrace folded the newspaper with deliberate care.

"An interesting question."

"I thought so."

"I wonder whether history agrees with you."

Blottisham settled into his chair.

"I expect it does."

Quillibrace regarded him thoughtfully.

"Why was number theory invented?"

Blottisham hesitated.

"For mathematics."

"To solve which practical problem?"

"I've no idea."

"Neither did the mathematicians."

Miss Stray smiled.

"They simply found the questions beautiful."

"Quite."

"And centuries later," Quillibrace continued, "their work became indispensable to cryptography, computing and modern physics."

Blottisham frowned.

"So they solved problems they didn't know existed."

"Precisely."

A brief silence followed.

Blottisham looked faintly suspicious.

"That's rather inconvenient."

"Reality often is."

Miss Stray leaned forward.

"I've always liked telescopes."

"So have astronomers."

"They don't merely let us see farther."

"No."

"They change what there is to look for."

Professor Quillibrace nodded.

"The microscope behaved in much the same fashion."

"It answered questions."

"And?"

"It created entirely new sciences."

Blottisham looked thoughtful.

"So every good answer produces more questions."

"Frequently."

"That sounds inefficient."

"It is gloriously inefficient."

The room fell into one of those companionable silences that seemed peculiar to old colleges.

Outside, sunlight briefly escaped from behind the clouds before changing its mind again.

Eventually Quillibrace spoke.

"I wonder whether we misunderstand the purpose of intelligence."

"In what way?"

"We imagine it exists to reduce uncertainty."

"Naturally."

"But what if..."

He paused.

"...its greatest achievements increase it?"

Blottisham looked genuinely alarmed.

"Surely that can't be right."

"Can it not?"

"If intelligence keeps creating more uncertainty..."

"...yes?"

"...won't we eventually know less rather than more?"

Miss Stray laughed softly.

"I don't think uncertainty is the opposite of knowledge."

"No?"

"It's often the consequence of discovering how much larger the world really is."

Blottisham considered this.

"So ignorance shrinks..."

"...yes?"

"...but mystery grows."

Professor Quillibrace smiled.

"A pleasing distinction."

Another silence settled over the room.

Miss Stray glanced at the shelves surrounding them.

"I've noticed something similar about favourite books."

"In what sense?" asked Quillibrace.

"The first time I read them, I looked for answers."

"And the second?"

"I noticed different questions."

"And the third?"

"I discovered I had become a different reader."

Blottisham looked puzzled.

"So the book changed?"

"No."

"You did."

"Partly."

She smiled.

"Though sometimes it feels as though the book had been waiting for me to catch up."

Quillibrace nodded approvingly.

"The finest books possess that curious quality."

"They're inexhaustible."

"They continue thinking after we've finished reading."

Blottisham frowned.

"Books don't think."

"No."

"But they continue provoking thought."

"I suppose they do."

Outside, the college chapel bell sounded the quarter-hour.

Its echo lingered briefly across the quadrangle.

Quillibrace looked towards the window.

"I once knew an exceptionally good supervisor."

"What made him exceptional?"

"He rarely answered questions."

Blottisham looked horrified.

"That seems rather poor supervision."

"So one might imagine."

"What did he do instead?"

"He asked better ones."

Miss Stray smiled immediately.

"I've known teachers like that."

"They're unforgettable."

"Why?"

"Because afterwards..."

She searched for the phrase.

"...the subject seemed much larger than before."

Blottisham stared into his teacup.

"I've been assuming education was about reducing confusion."

"It often is."

"But perhaps..."

Quillibrace looked at him kindly.

"...it is also about enlarging possibility."

Another silence.

The afternoon seemed unusually still.

At length Blottisham spoke again.

"I've noticed something curious."

"What is it?"

"When I have a particularly good conversation..."

"...yes?"

"...I rarely leave feeling certain."

Miss Stray nodded.

"What do you leave feeling?"

"Interested."

Professor Quillibrace smiled.

"An admirable condition."

"I usually have three new ideas."

"Good."

"And six new questions."

"Better."

Blottisham laughed quietly.

"So perhaps the conversation hasn't solved my problem."

"No?"

"It's changed the size of the world."

The sentence hung gently in the room.

No one hurried to improve it.

Outside, a group of students crossed the quadrangle carrying telescopes towards the observatory.

Miss Stray watched them disappear beneath the archway.

"They think they're going to look at the stars."

Professor Quillibrace followed her gaze.

"They are."

"But they'll come back with rather more sky than they expected."

He stood and walked slowly to the window.

"When I was young," he said after a while, "I believed the horizon marked the edge of the landscape."

Blottisham joined him.

"And now?"

Quillibrace looked towards the distant hills beyond the college.

"Now I suspect the horizon has another occupation."

"What is that?"

"It retreats."

Miss Stray came to stand beside them.

"So the purpose of intelligence..."

"...yes?"

"...is not to reach the horizon."

Professor Quillibrace smiled.

"No."

"It is to keep discovering that there is one."

For a long while, none of them spoke.

The college lay quietly beneath the late afternoon light.

Beyond the gardens, beyond the fields, beyond the hills themselves, the horizon rested exactly where it always had.

Far enough away to invite another journey.

Close enough to suggest there might yet be another world beyond it.

VII: The Question That Went Missing

Mr Blottisham entered the Senior Common Room carrying a notebook filled with numbered questions.

Professor Quillibrace glanced up.

"You appear organised."

"I've become methodical."

"How alarming."

"I've discovered that the secret of clear thinking is asking the right questions."

Miss Stray smiled.

"A most encouraging beginning."

"I've written them all down."

"All of them?"

"The important ones."

Professor Quillibrace accepted the notebook.

He turned several pages in silence.

"This is an ambitious list."

"It covers everything."

"I notice Question Seven."

"What about it?"

"'What is intelligence?'"

"A fundamental enquiry."

"Certainly."

"And Question Eight follows immediately afterwards."

"'Can machines possess it?'"

"Exactly."

Quillibrace closed the notebook and returned it.

"I'm curious."

"About what?"

"What happens if neither question is the interesting one?"

Blottisham frowned.

"Then I've numbered them incorrectly."

Miss Stray laughed.

"I don't think that's quite what he means."

"No?"

Professor Quillibrace leaned back.

"Have you ever begun investigating one thing..."

"...yes?"

"...and discovered something entirely different?"

"Frequently."

"So your original question disappeared."

"It was answered."

"Was it?"

Blottisham hesitated.

"Sometimes."

"And sometimes?"

"It simply..."

He searched for the phrase.

"...ceased to matter."

The room became quietly attentive.

Miss Stray rested her notebook on her knee.

"I've often noticed that while teaching."

"In what sense?" asked Quillibrace.

"A student asks a perfectly sensible question."

"Naturally."

"I begin answering it."

"And?"

"Halfway through I realise they should have asked something else."

Professor Quillibrace nodded.

"The finest tutorials often proceed in precisely that fashion."

Blottisham looked puzzled.

"Isn't that rather frustrating?"

"For whom?"

"The student."

Miss Stray smiled.

"Not if the second question is better than the first."

Blottisham looked unconvinced.

"I've always regarded questions as fixed."

Quillibrace raised an eyebrow.

"Like paving stones?"

"Something of the sort."

"I wonder."

He wandered towards the window.

"How was penicillin discovered?"

"By accident."

"The microwave?"

"I believe so."

"X-rays?"

"The same."

"So scientific discovery..."

He turned.

"...has a curious habit of wandering away from its original intentions."

Blottisham nodded slowly.

"I hadn't connected those examples."

"Most discoveries refuse to respect our plans."

Outside, a gardener was attempting to wheel a barrow across the damp lawn.

The wheel promptly found a rut invisible from the window.

Miss Stray watched him alter course.

"There."

Quillibrace smiled.

"An illustration."

"Of what?"

"He intended one route."

"The ground suggested another."

"The destination remains the same."

"Perhaps."

"But the path has changed."

Blottisham looked thoughtful.

"I see."

"Do you?"

"I'm not sure."

"Excellent."

Another comfortable silence followed.

Eventually Miss Stray spoke again.

"I've also noticed something about conversations."

"What is that?"

"The best ones don't simply answer questions."

"No?"

"They produce better ones."

Professor Quillibrace looked quietly pleased.

"I've long suspected as much."

Blottisham frowned.

"Surely answers are the objective."

"Sometimes."

"But suppose the answer reveals a hidden assumption."

"Then one asks another question."

"And if that question reveals another distinction?"

"One asks another."

"And another."

"Yes."

"So what is the conversation really producing?"

Blottisham looked into the fire.

"...questions."

"Better questions."

"I think so."

The room fell silent again.

Outside, the gardener had abandoned the original path entirely.

The barrow now approached its destination from the opposite direction.

Miss Stray watched with quiet amusement.

"It rather resembles exploration."

"In what way?" asked Blottisham.

"You don't merely travel."

"You discover the country."

Professor Quillibrace nodded.

"And the map changes."

Blottisham looked puzzled.

"I thought maps were fixed."

"So did the explorers."

Another pause.

Then Blottisham spoke almost hesitantly.

"I've been using one of these conversational systems rather a lot."

Neither of the others appeared surprised.

"I ask a question."

"And?"

"It answers."

"As expected."

"But then..."

He looked faintly embarrassed.

"...I realise I should have asked something different."

Miss Stray smiled.

"So you ask again."

"Yes."

"And again."

"Yes."

"And eventually?"

"I've forgotten what I originally wanted to know."

Professor Quillibrace looked at him over the rim of his spectacles.

"Disappointing?"

Blottisham considered.

"No."

"Interesting?"

"Very."

"What have you been doing all that time?"

"I thought I was looking for answers."

"And now?"

He took rather longer over the reply.

"I think..."

"...yes?"

"...I've been learning how to ask."

No one spoke.

The sentence seemed unexpectedly complete.

Outside, the gardener finally reached the flowerbeds.

The route bore almost no resemblance to the one with which he had begun.

Yet he appeared perfectly satisfied.

Miss Stray watched him for a moment before speaking.

"Perhaps that is always the way."

"What is?"

"Good thinking."

Professor Quillibrace looked towards the window.

"It rarely arrives where it intended."

He turned back towards the room.

"But it very often arrives somewhere worth visiting."

The college clock began to strike the hour.

Neither Blottisham nor Miss Stray moved.

After a while Blottisham quietly closed the notebook containing his carefully numbered questions.

He did not cross any of them out.

He merely turned to a blank page.

At the top, he wrote only a single sentence.

What have I forgotten to ask?

Professor Quillibrace noticed.

He said nothing.

There seemed very little to improve.

VI: More Than the Sum of Its Parts

The afternoon's tranquillity was interrupted by the sound of a string quartet drifting faintly across the quadrangle.

Mr Blottisham paused in the middle of buttering a crumpet.

"The second violin is late."

Miss Stray looked up.

"I think they're rehearsing."

"They've started without him."

Professor Quillibrace listened for a moment.

"No."

"They have."

"I suspect they've merely reached a passage where he has nothing to play."

Blottisham looked unconvinced.

"It sounds incomplete."

"It should."

"Why?"

"Because chamber music is remarkably intolerant of absences."

Blottisham resumed his assault upon the crumpet.

"If one violinist failed to arrive..."

"...yes?"

"...you'd simply have three-quarters of a quartet."

Professor Quillibrace smiled.

"Would you?"

"Obviously."

Miss Stray shook her head.

"I don't think that's how quartets work."

"Why not?"

"Because every player alters every other player."

Blottisham frowned.

"They simply play their notes."

"Do they?"

"Aren't they written down?"

"So is punctuation."

"I'm not following."

Quillibrace closed his book.

"Suppose the cellist chooses a slightly slower tempo."

"Very well."

"What must the others do?"

"Keep up."

"And if the first violin lingers over a phrase?"

"They adjust."

"And if the viola brings out an inner melody?"

"The balance changes."

"So what, precisely, is each musician playing?"

Blottisham opened his mouth.

Then stopped.

"The others."

Miss Stray smiled.

"In part."

A thoughtful silence settled over the room.

Outside, the quartet had reached a passage of remarkable delicacy.

Professor Quillibrace listened with evident satisfaction.

"We have an unfortunate habit."

"What habit?" asked Blottisham.

"We imagine collaborations to be simple arithmetic."

"Isn't that what they are?"

"Two minds plus two minds equals..."

"...four minds?"

"Does it?"

Blottisham looked uncertain.

"It sounds mathematically respectable."

"Reality often disregards respectable mathematics."

Miss Stray laughed.

"I've noticed."

Quillibrace continued.

"Consider a scientific discovery."

"Very well."

"One researcher proposes a hypothesis."

"Yes."

"Another notices a weakness."

"Useful."

"A third sees an implication."

"Excellent."

"The original proposal is revised."

"Naturally."

"The criticism changes."

"The hypothesis changes again."

"Eventually..."

He paused.

"...whose discovery is it?"

Blottisham rubbed his chin.

"Everyone's?"

"In what proportion?"

"I don't know."

"Precisely."

Miss Stray rested her notebook on the arm of her chair.

"I think we're rather attached to accounting."

"Accounting?"

"We want ideas to have owners."

"That seems reasonable."

"We want discoveries to have percentages."

"Yes."

"We imagine collaboration as though everyone contributes fixed quantities."

Blottisham nodded.

"Exactly."

"And perhaps..."

She looked towards Quillibrace.

"...that isn't what happens."

Professor Quillibrace inclined his head.

"Perhaps not."

The quartet outside had fallen silent.

A moment later the players began again from several pages earlier.

Blottisham smiled.

"They've started over."

"Indeed."

"They're correcting mistakes."

"Perhaps."

"Or perhaps they're discovering a different interpretation."

Blottisham looked thoughtful.

"I hadn't considered that."

Quillibrace rose and wandered towards the window.

"There is another curious example."

"What is it?"

"Ants."

Blottisham sighed.

"We've progressed from trees to ants."

"And birds."

"I suppose fungi will return eventually."

"They usually do."

Miss Stray laughed.

"What about ants?"

Professor Quillibrace looked out across the lawns.

"A single ant is not especially impressive."

"I've never been intimidated by one."

"Quite."

"Yet together..."

"...yes?"

"...they construct astonishing societies."

"They do."

"No ant understands the entire colony."

"I assume not."

"No ant designs the architecture."

"No."

"And yet..."

Blottisham finished quietly,

"...the colony behaves intelligently."

Professor Quillibrace turned.

"So it appears."

"The intelligence isn't inside one ant."

"No."

"It's..."

He hesitated.

"...the pattern."

Miss Stray looked delighted.

"The relationships."

"Quite."

The room became unusually quiet.

At length Blottisham asked,

"Scientists have a word for that, don't they?"

"They do."

"I've forgotten it."

"Emergence."

He repeated it carefully.

"Emergence."

"As when a flock of birds wheels through the sky."

"No bird directs the movement."

"No."

"But together they produce something extraordinary."

Blottisham nodded slowly.

"I've always found that rather beautiful."

"As have I."

Miss Stray looked thoughtful.

"I wonder whether conversations sometimes work like that."

"In what sense?"

"No one directs them."

"Usually not."

"No one knows exactly where they're going."

"Certainly."

"And yet..."

She smiled.

"...occasionally they arrive somewhere astonishing."

Professor Quillibrace looked quietly pleased.

"A promising hypothesis."

Another silence settled over the room.

Eventually Blottisham spoke again.

"So perhaps intelligence isn't always something one possesses."

"...yes?"

"Sometimes it's something one participates in."

Neither of the others answered immediately.

The observation seemed to deserve a little space.

Outside, the quartet had resumed.

This time the music sounded unexpectedly transformed.

"The second violin has returned," said Blottisham.

"I believe he was there all along," replied Miss Stray.

"Oh."

Blottisham listened again.

"It sounds completely different now."

Professor Quillibrace smiled.

"Curious."

"Why?"

"You've just demonstrated the point."

"I have?"

"You assumed the music consisted of individual performers."

"I did."

"And now?"

Blottisham continued listening for several moments before replying.

"Now I'm not entirely sure where the music is."

No one attempted to answer.

The notes drifted through the open window, each phrase quietly altering the next.

After a while Miss Stray spoke almost to herself.

"Perhaps that is always the difficulty."

"What is?"

"We keep looking for remarkable things inside remarkable individuals."

Professor Quillibrace looked towards the musicians somewhere beyond the college walls.

"And occasionally," he said softly, "the remarkable thing turns out to be the relationship."

The room fell silent once more.

Not because the conversation had ended.

But because, for a little while, none of them wished to interrupt what was now happening between them.

V: Where Do Ideas Come From?

Mr Blottisham was writing with unusual determination.

After several minutes he placed his pen upon the table and regarded the page with satisfaction.

"There."

Professor Quillibrace looked up.

"Finished?"

"I've had an idea."

"Congratulations."

"I've written it down before it escaped."

Miss Stray smiled.

"An excellent precaution."

Blottisham tapped the notebook.

"Now it's safely mine."

Professor Quillibrace removed his spectacles.

"'Mine'?"

"The idea."

"I see."

"You sound doubtful."

"I am merely curious."

"In what way?"

Quillibrace leaned back.

"Where did it come from?"

"My head."

"Entirely?"

Blottisham looked mildly offended.

"Where else?"

Miss Stray closed the novel she had been reading.

"I've never been completely certain."

"About what?"

"Where ideas begin."

Blottisham looked puzzled.

"They begin when one thinks of them."

"Do they?"

"Obviously."

She considered this.

"When I write..."

"...yes?"

"...I usually begin with something rather vague."

"So?"

"Then one sentence suggests another."

"A sensible arrangement."

"But the second sentence often changes the meaning of the first."

"It refines it."

"Sometimes it completely overturns it."

Blottisham frowned.

"So you rewrite."

"Yes."

"And eventually I discover I'm writing about something I hadn't realised interested me."

Professor Quillibrace smiled.

"A familiar experience."

Blottisham looked from one to the other.

"You both make writing sound remarkably disorganised."

"It usually is."

"I assumed authors knew where they were going."

"Many do."

"And the rest?"

"They find out."

A brief silence settled over the room.

Blottisham looked unconvinced.

"The idea must still have existed beforehand."

"Must it?"

"Otherwise where did it come from?"

Quillibrace reached for the teapot.

"I once asked a physicist precisely that question."

"What did he say?"

"He thought for nearly a minute."

"And?"

"'I honestly don't know.'"

Blottisham laughed.

"Physicists aren't usually allowed to say that."

"They should be more often."

Miss Stray rested her chin lightly upon one hand.

"I've heard composers say similar things."

"They hear music?"

"They begin with a fragment."

"Go on."

"Then the fragment suggests a harmony."

"Naturally."

"The harmony changes the rhythm."

"I suppose."

"The rhythm changes the entire character of the piece."

"So the original idea disappears?"

"No."

"It grows."

Quillibrace nodded.

"Or perhaps..."

"...yes?"

"...it emerges."

Blottisham repeated the word quietly.

"Emerges."

No one spoke for a few moments.

Outside, somewhere across the quadrangle, a piano was being practised with more enthusiasm than precision.

Miss Stray listened for a moment.

"That student has just made exactly the same mistake three times."

"An admirable consistency."

"But each repetition is slightly different."

Professor Quillibrace smiled.

"So the music is teaching the pianist."

"I think so."

Blottisham looked doubtful.

"Music doesn't teach."

"No?"

"It merely..."

He stopped.

"...answers back."

The room became unexpectedly quiet.

Miss Stray looked at him with unmistakable amusement.

"You've just contradicted yourself."

"I have?"

"You've spent the last week insisting that conversations matter because they answer."

"I remember."

"And now you've noticed that writing does something similar."

Blottisham stared at his notebook.

"I think..."

"...yes?"

"...I've always imagined writing as recording thoughts."

"Most of us have."

"But when I cross something out..."

"...go on."

"...I'm actually responding to something the page has shown me."

Professor Quillibrace nodded approvingly.

"The page changes the landscape."

"It makes possibilities visible."

"Exactly."

Another silence settled over the room.

After a while Quillibrace asked,

"Have either of you ever left a conversation unable to remember whose idea something was?"

Miss Stray laughed immediately.

"Frequently."

"So have I."

"We remember arriving somewhere."

"Yes."

"But not precisely how."

"Nor who first suggested the crucial step."

Blottisham looked thoughtful.

"I've had that experience."

"And?"

"I never regarded it as philosophically significant."

"It may be."

"In what way?"

"Suppose the final idea belonged..."

Quillibrace paused.

"...not to either speaker individually..."

"...yes?"

"...but to the conversation."

Blottisham looked at the fire.

"Rather like the forest."

"Quite."

"Or chamber music."

"Indeed."

"Or science."

"Precisely."

Miss Stray smiled.

"We seem to be collecting metaphors."

"No."

Professor Quillibrace shook his head gently.

"I rather think they're collecting us."

That remark lingered.

Outside, the piano had progressed to something considerably more confident.

The earlier mistakes had not vanished.

They had become part of the performance.

Eventually Blottisham spoke.

"If ideas really emerge..."

"...yes?"

"...then perhaps asking who owns them is sometimes the wrong question."

"What would be the better one?"

He looked around the room.

The books.

The notebooks.

The piano music drifting faintly through the open window.

The conversation that had somehow carried them all further than any had intended.

"Perhaps..."

He smiled.

"...we should ask what kinds of conversations make them possible."

Professor Quillibrace reached quietly for his teacup.

"I cannot improve upon that."

No one attempted to.

For several minutes they simply sat together while the afternoon unfolded around them—three minds, a room full of books, and an idea that none of them could honestly claim to have produced alone.

IV: The Forest That Wasn't About Trees

Mr Blottisham was examining an illustrated book on woodland ecology with the determined expression of a man who expected nature to become simpler if stared at firmly enough.

Professor Quillibrace looked up from his correspondence.

"Making progress?"

"I've discovered something deeply suspicious."

"Oh?"

"The trees are apparently talking to one another."

Miss Stray looked over.

"Through fungal networks?"

Blottisham looked disappointed.

"So you've heard this nonsense as well."

"I have."

"They exchange nutrients."

"So it seems."

"They respond collectively to disease."

"Apparently."

"They even influence one another's growth."

"So the biologists tell us."

Blottisham closed the book with theatrical resignation.

"In my day, trees simply stood about."

Quillibrace smiled.

"They still do."

"They're becoming unnecessarily complicated."

"Or perhaps," said Miss Stray, "we're becoming better at noticing them."

Blottisham frowned.

"I don't understand why everyone is so excited."

"Because," said Quillibrace, "the forest turned out not to be what we thought it was."

"It's trees."

"Certainly."

"Lots of them."

"Undeniably."

"So what's changed?"

Professor Quillibrace folded his letter.

"For rather a long time we imagined a forest was simply a large number of trees occupying the same location."

"Which sounds perfectly sensible."

"It does."

"And now?"

"Now it appears that many of the forest's most interesting properties belong..."

He paused.

"...not to the trees individually..."

"...yes?"

"...but to the relationships between them."

Blottisham looked unconvinced.

"Trees remain the important part."

Miss Stray tilted her head.

"Do they?"

"What else could be?"

"The fungi."

"They're mushrooms."

"They're not mushrooms."

"Well..."

"They're fungi."

"That doesn't improve matters."

Quillibrace chuckled.

"The rivers matter."

"I suppose."

"The soil."

"Yes."

"The insects."

"Unfortunately."

"The birds."

"Certainly."

"The bacteria."

Blottisham sighed.

"Very well."

"So where," Quillibrace asked gently, "does the forest actually reside?"

Blottisham blinked.

"In..."

He looked towards the window, beyond which the college gardens were shimmering after the morning rain.

"...all of it?"

"Quite."

Miss Stray smiled.

"It's difficult to point to one tree and say, 'There's the forest.'"

"No one would."

"Exactly."

The room became quiet.

After a while Blottisham spoke again.

"I feel I've heard this argument before."

"You have."

"It wasn't about trees."

"No."

"It was about intelligence."

Quillibrace inclined his head.

"You are becoming alarmingly attentive."

"I dislike repeating philosophical mistakes."

"A healthy instinct."

Miss Stray rested her notebook on her lap.

"We've always asked who is intelligent."

"A sensible question."

"Perhaps."

"But we've rarely asked..."

She looked towards Quillibrace.

"...what intelligence depends upon."

Professor Quillibrace nodded.

"An altogether different enquiry."

Blottisham frowned.

"So you're saying minds are like forests?"

"I'm saying the comparison is suggestive."

"In what way?"

Quillibrace gestured towards the shelves surrounding them.

"Where would science exist if every scientist worked entirely alone?"

"It wouldn't."

"No journals."

"No."

"No laboratories."

"No."

"No criticism."

"No conferences."

"No correspondence."

"No students."

"No teachers."

Blottisham laughed.

"It would simply be thousands of people having excellent ideas that nobody else ever heard."

"An admirable description."

"So science isn't merely scientists."

"No."

"It's..."

He paused.

"...everything connecting them."

"Precisely."

Miss Stray looked thoughtful.

"The same is true of music."

Blottisham smiled.

"You're going to mention chamber music again."

"I wasn't."

"Oh."

"I was thinking of Bach."

"Go on."

"We speak of Bach as though he appeared from nowhere."

"We rather do."

"But he inherited traditions."

"He did."

"Others performed his music."

"They still do."

"Teachers passed those techniques onward."

"Yes."

"Composers responded."

"Indeed."

"So where exactly..."

She smiled.

"...does the music end?"

Blottisham considered the question longer than usual.

"I'm beginning to suspect these boundaries are less tidy than I'd prefer."

Quillibrace looked quietly pleased.

"Reality often disappoints tidy minds."

Another silence settled over the room.

Outside, a blackbird landed briefly upon the lawn before disappearing beneath a hedge.

Miss Stray watched it go.

"I've also been wondering about language."

"In what sense?"

"We inherit every word."

"Certainly."

"Every concept."

"Yes."

"Every distinction."

"Indeed."

"So even when I think privately..."

"...yes?"

"...I'm using tools fashioned by countless other people."

Professor Quillibrace smiled.

"A rather crowded solitude."

Blottisham looked into his teacup.

"So perhaps individual thought has always depended upon larger systems."

"I believe so."

"But now..."

He hesitated.

"...those systems contain rather different participants."

No one answered immediately.

At length Quillibrace asked,

"What sort of participants?"

"Books."

"Still."

"People."

"Naturally."

"Libraries."

"Of course."

"And now..."

Blottisham searched for the phrase.

"...conversational systems."

Miss Stray nodded.

"They remember differently."

"They search differently."

"They notice different patterns."

"They make different mistakes."

"They certainly do."

Blottisham smiled.

"So they're rather like fungi."

Professor Quillibrace laughed—a rare enough occurrence that both the others looked momentarily surprised.

"I doubt the engineers will adopt that description."

"But it's not entirely wrong."

"No."

"They're not people."

"No."

"They're not books."

"No."

"They're something else."

"Exactly."

The laughter subsided.

For several minutes no one spoke.

The silence was unusually thoughtful.

Finally Miss Stray broke it.

"Perhaps we've spent too long asking whether every participant resembles a human mind."

Quillibrace looked at her.

"And what should we ask instead?"

She looked around the room—the books, the notebooks, the windows, the shelves, the three cups of tea slowly cooling on the table.

"Perhaps we should ask what kinds of communities allow thinking itself to flourish."

Professor Quillibrace did not answer immediately.

When he finally spoke, it was almost absent-mindedly.

"Forests become healthier by increasing the richness of their relationships."

Blottisham nodded slowly.

"So perhaps..."

Neither of the others interrupted.

"...the future belongs less to the cleverest tree..."

He glanced at the ecology book and smiled to himself.

"...than to the best forest."

Outside, the afternoon breeze moved gently through the college elms.

No single tree appeared to be doing very much.

Together, they made the unmistakable sound of a woodland.
