The Senior Common Room was unusually animated.
Mr Blottisham had returned from a weekend conference.
This was rarely conducive to tranquillity.
Professor Quillibrace was reading.
Miss Stray was writing.
Blottisham entered carrying a laptop and an expression suggesting that history had occurred.
"It understands me."
Quillibrace lowered his book.
"Who does?"
"The machine."
"I see."
"It genuinely understands me."
Miss Stray looked up.
"That sounds significant."
"It is."
Blottisham sat down heavily.
"I spent three hours talking with it."
"Three hours?"
"Nearly four."
"Good heavens."
"It was extraordinary."
Quillibrace closed his book.
This had become something of a reflex.
"What happened?"
Blottisham leaned forward.
"We discussed literature."
"Yes?"
"Music."
"Indeed."
"Regret."
"Ah."
"Memory."
"I see."
Blottisham paused.
"It felt different."
The room became quiet.
For the first time that afternoon, neither Quillibrace nor Stray responded immediately.
After a moment Quillibrace said:
"Different from what?"
"Different from ordinary software."
"How?"
Blottisham searched for words.
"It felt..."
He hesitated.
"As though there was somebody there."
The silence lingered.
Miss Stray closed her notebook.
Quillibrace remained thoughtful.
At length he said:
"I do not doubt that it felt that way."
Blottisham blinked.
"You do not?"
"No."
"I had expected resistance."
"To what?"
"The experience."
"My dear Blottisham, experiences are among the few things difficult to dispute."
Blottisham looked pleased.
"There we are then."
"Not quite."
"Of course not."
Quillibrace stood and wandered toward the fireplace.
"What precisely do you conclude from the experience?"
"That the machine understands."
"Because it felt as though someone was there."
"Exactly."
Quillibrace nodded.
"I wonder."
Blottisham sighed.
"There it is."
"What?"
"The wonder."
"It has served us reasonably well so far."
Miss Stray smiled.
Blottisham ignored her.
"What do you wonder?"
"I wonder whether we have identified the location of the experience."
"The location?"
"Yes."
Blottisham frowned.
"It occurred in the machine."
"Did it?"
"Where else would it occur?"
Quillibrace considered.
"In the conversation."
The room became quiet.
Blottisham looked unconvinced.
"That sounds evasive."
"It is not intended to be."
Miss Stray leaned forward.
"I think I understand."
"Then perhaps you could explain it to me."
"Gladly."
She looked at Blottisham.
"When you listen to a string quartet, where does the music occur?"
"In the room."
"Partly."
"And?"
"In the instruments."
"Partly."
She paused.
"And also in the listening."
Blottisham frowned.
"That sounds suspiciously philosophical."
"It probably is."
Quillibrace nodded approvingly.
"The interesting thing about conversations is that they are difficult to locate."
"What does that mean?"
"Does the conversation exist entirely in one participant?"
"No."
"The other?"
"No."
"Then where?"
Blottisham looked mildly alarmed.
"I dislike questions that begin like this."
"Reasonable."
Miss Stray continued.
"When you say it felt as though somebody was there, I do not doubt the feeling."
"Good."
"What I am uncertain about is why you assume the feeling originated entirely inside the machine."
Blottisham paused.
For a moment he seemed genuinely puzzled.
"I had not considered that."
"No."
"You think it originated inside me?"
"Not entirely."
"Then where?"
She smiled.
"In the interaction."
The silence returned.
Quillibrace resumed.
"Consider what happened."
"Very well."
"You brought memories."
"Yes."
"You brought expectations."
"Naturally."
"You brought interpretations."
"Of course."
"The machine brought language."
"Yes."
"The conversation emerged from all of these together."
Blottisham thought about this.
"That seems true."
"And yet," said Quillibrace, "you have assigned the entire result to one side of the interaction."
The room fell quiet again.
After a while Blottisham said:
"That is rather unfair."
"To whom?"
"To me."
Miss Stray laughed.
"Possibly."
Blottisham looked down at the laptop.
"I still feel that it understood me."
"Perhaps it did."
The answer came from Quillibrace.
Blottisham looked up sharply.
"You think so?"
"I think we should be careful."
"About what?"
"About what the word 'understood' is doing."
Blottisham groaned.
"Naturally."
"Suppose understanding is not a substance."
"Oh dear."
"Suppose it is not a hidden thing located inside one participant."
"This is becoming very inconvenient."
"Suppose understanding is something that occurs in successful interaction."
Miss Stray nodded slowly.
"That would explain why conversations sometimes feel meaningful without requiring us to locate a soul."
The room became quiet once more.
Outside, rain had begun to fall lightly against the windows.
Blottisham stared at the laptop.
The machine remained exactly where it had been.
The conversation remained exactly as memorable.
The feeling remained exactly as powerful.
Only its location had become uncertain.
After several minutes he spoke.
"I am beginning to suspect that half our disagreements arise from trying to locate things that may not possess locations."
Quillibrace smiled.
"A promising suspicion."
"I dislike it."
"Also promising."
Miss Stray gathered her notebook.
"You know what this reminds me of?"
"What?" said Blottisham.
"The old séances."
Blottisham looked puzzled.
"Séances?"
"The participants would gather around a table."
"Yes."
"They would experience something meaningful."
"Indeed."
"The debate would immediately become whether the experience proved the existence of spirits."
Blottisham laughed.
"I see."
"And?"
"And perhaps the more interesting question was how the experience was produced in the first place."
The room fell silent.
Outside, the rain continued.
Inside, the machine sat quietly on the table.
Neither spirit nor fraud.
Neither person nor appliance.
Simply a participant in an interaction whose significance remained, as ever, a matter of interpretation.
Quillibrace reopened his book.
Blottisham closed his laptop.
And for a few minutes all three sat listening to the rain, each privately wondering whether some of the most important things in life might occur not inside entities, but between them.
