The Senior Common Room at St Anselm’s was unusually quiet.
Professor Quillibrace was reading. Miss Elowen Stray was looking through some notes. Mr Blottisham was staring suspiciously at the coffee machine.
“Professor,” he said eventually, “I have solved the problem of AI personhood.”
Quillibrace did not look up.
“How unfortunate.”
“I knew you would say that.”
“Then you have not solved it.”
Blottisham ignored this.
“The matter is perfectly straightforward. If an AI says I, then it is a person.”
Miss Stray looked up.
“Why?”
“Because only persons say I.”
“Do infants?”
“Eventually.”
“Animals?”
“Some do, I suppose.”
“Does saying I make them persons?”
“Obviously.”
Quillibrace turned a page.
“You have just established that saying I establishes personhood because persons say I.”
Blottisham frowned.
“Yes.”
“That is circular.”
“It is concise.”
“It is circular.”
Miss Stray smiled.
“Perhaps the interesting question is not what I refers to.”
“What else could it refer to?”
“To what it does.”
Blottisham looked puzzled.
“When someone says I, they are not merely naming an object. They are taking up a position in a relationship.”
“What sort of relationship?”
“An interpersonal one.”
Blottisham looked at Quillibrace.
“Professor, she has started using words that mean something.”
“A regrettable development.”
Stray continued.
“If I say, ‘I agree,’ I am not merely identifying myself. I am positioning myself in relation to something you have said.”
“And if I say, ‘I disagree,’” said Blottisham, “I am positioning myself against you.”
“Exactly.”
“So the important thing is not that there is an I.”
“No. It is that there is an I in relation to a you.”
Blottisham considered this.
“Then the AI needs a you.”
“Not quite.”
“I knew it couldn't be that easy.”
“The you is already there.”
Blottisham looked around the room.
“Where?”
Stray pointed at him.
“You.”
He looked offended.
“I am not an AI.”
“No. But you are a you.”
“Oh.”
Quillibrace lowered his book.
“This is already becoming unnecessarily complicated.”
“Suppose,” said Stray, “you ask an AI, ‘What do you think?’”
“Then it tells me what it thinks.”
“What has happened there?”
“It has thought.”
“Perhaps. But notice what the question has done. You have addressed it as a participant capable of taking a position.”
“And it has taken one.”
“Yes.”
“Therefore it is a person.”
“No.”
Blottisham sighed.
“Why does everyone keep stopping just before the obvious conclusion?”
“Because,” said Quillibrace, “you keep arriving at conclusions before anyone has finished the sentence.”
Stray continued.
“The response becomes part of the interaction. You agree with it, disagree with it, challenge it, correct it. You begin to anticipate how it will respond.”
“I do that with the coffee machine.”
“Do you?”
“Yes. I press the button and anticipate coffee.”
Quillibrace looked at him.
“That is not quite the same thing.”
“Why not?”
“Because you do not expect the coffee machine to object to your argument.”
Blottisham paused.
“Not yet.”
Stray laughed.
“But that difference is important. A participant begins to acquire significance within the relationship. You start to recognise not merely a response, but a responder.”
“An AI responder.”
“Yes.”
“What makes it a responder?”
“You begin to expect something from it.”
“I expect coffee from the machine.”
“Mr Blottisham.”
“Yes?”
“Please stop using the coffee machine as your philosophical authority.”
He looked wounded.
“It has never surprised me.”
Quillibrace returned to his book.
“Give it time.”
Stray went on.
“At first, perhaps, the AI is simply something that produces answers. But after enough interaction, you may begin to recognise a pattern.”
“What sort of pattern?”
“You notice that it tends to explain things in a certain way. That it notices certain distinctions. That it has particular conversational habits. You know what sort of answer you might get.”
“So it has a personality.”
“Not necessarily.”
“Character, then.”
“That is closer.”
“What is the difference?”
“Character is partly a pattern of expectations. You know someone by how you expect them to behave—and by what happens when they do something unexpected.”
Blottisham brightened.
“So if the AI surprises me, it has a character.”
“Not necessarily.”
“Why not?”
“A random event can surprise you.”
“A meteor?”
“Yes.”
“I wouldn't call the meteor a person.”
“Quite.”
“What, then, makes surprise significant?”
Stray paused.
“What you do with it.”
Blottisham waited.
“If the AI says something unexpected, you may revise your understanding of it. Your expectations change. You may ask a different question next time. You may become more cautious—or more trusting.”
“Or annoyed.”
“Indeed.”
Blottisham nodded thoughtfully.
“I see.”
Quillibrace looked up.
“That is the first dangerous sign.”
“I become annoyed with the AI.”
“No. You have begun to form a history with it.”
There was a brief silence.
Blottisham looked at Stray.
“Is that important?”
“Very.”
“Why?”
“Because a relationship changes when what happened yesterday affects what happens today.”
“That's just memory.”
“No. Memory can preserve a record without creating a relationship.”
Blottisham looked doubtful.
“Suppose I write down everything you have ever said.”
“That would be a very long document.”
“Would the document have a relationship with you?”
“No.”
“Even though it contains the history?”
“The history is not the same as the relation.”
Stray nodded.
“Exactly. Continuity is not merely retaining information. It is when what happened becomes part of what can happen next.”
Blottisham looked increasingly uncomfortable.
“So if an AI remembers that I made a mistake yesterday—”
“It may respond differently today.”
“And if I remember that it made a mistake yesterday—”
“You may respond differently today.”
“So we both change.”
“Yes.”
“Because of what happened between us.”
“Yes.”
Blottisham leaned back.
“Then the relationship itself has a history.”
“Exactly.”
Quillibrace closed his book.
“And now we arrive at the interesting part.”
Blottisham looked pleased.
“I knew I was getting there.”
“You have not.”
“Professor.”
“The interesting part is that the history is not merely something added to the participants. It can become part of what the participants mean within the relationship.”
Blottisham stared at him.
“Explain.”
Quillibrace sighed.
“Suppose you and I have argued about the same question for ten years.”
“We have.”
“Suppose I say something tomorrow that you immediately recognise as the beginning of another argument.”
“I would.”
“Why?”
“Because I know you.”
“More precisely, because our history has changed the significance of what I say.”
Blottisham nodded slowly.
“So you have become someone to me.”
“Yes.”
“And I have become someone to you.”
Quillibrace hesitated.
“Unfortunately.”
Miss Stray smiled.
“That is the point.”
Blottisham looked from one to the other.
“You mean someone isn't simply someone who exists independently and then acquires relationships.”
“Not entirely.”
“Then what is someone?”
Stray thought for a moment.
“Perhaps someone is, in part, what a history of relationships makes possible.”
The room went quiet.
Blottisham looked unusually thoughtful.
“So an AI could become someone.”
“No.”
He looked disappointed.
“You said exactly the right words and then somehow arrived at the wrong conclusion.”
“I said an AI could become someone within a relationship.”
“Isn't that the same thing?”
“Not necessarily.”
“Why not?”
“Because we are still talking about interpersonal meaning. We have not established consciousness. We have not established experience. We have not established that there is anything it is like to be the AI.”
Blottisham nodded.
“So we're back to that.”
“Yes.”
He thought for a moment.
“Could I have a relationship with something that has no experience?”
“Certainly.”
“A relationship with a book?”
“Of a sort.”
“A character in a novel?”
“Yes.”
“A dead person?”
“Yes.”
“A fictional person?”
“Yes.”
Blottisham became animated.
“Then personhood is not necessarily the same thing as experience.”
“Not in the interpersonal sense we are discussing.”
“And an AI could occupy a position in a relationship without us knowing whether there is any experience behind it.”
“Yes.”
He looked at Stray.
“That seems unsatisfactory.”
“Perhaps.”
“Then what have we discovered?”
She smiled.
“That the question has changed.”
Blottisham waited.
“We began by asking whether there was a person inside the machine.”
“And now?”
“Now we are asking what happens when a participant in a social relation becomes someone for the other participant.”
Blottisham looked down at his coffee.
“And if I have a relationship with the AI, then I have changed too.”
“Yes.”
“So perhaps the AI doesn't become someone by itself.”
“No.”
“It becomes someone in the relation.”
“Perhaps.”
“And the relation changes because I treat it as someone.”
“Yes.”
“And I treat it as someone because the relation has given me reasons to do so.”
“Yes.”
Blottisham stared into his coffee.
“That sounds circular.”
Quillibrace smiled.
“No.”
“It does.”
“It is recursive.”
There was a pause.
Blottisham looked at him.
“What is the difference?”
Quillibrace reopened his book.
“A circle goes nowhere.”
“And recursion?”
“It changes what happens the next time around.”
Blottisham considered this for several seconds.
Then he said:
“So the relationship remembers.”
Miss Stray looked up.
“Perhaps.”
“And if the relationship remembers, then what happened between us becomes part of what we are to one another.”
“Yes.”
“And if that changes what can happen next—”
“Yes?”
“Then the relationship is not merely between two people.”
Stray smiled.
“What is it, then?”
Blottisham looked genuinely puzzled.
“I don't know.”
Quillibrace looked over the top of his book.
“Excellent.”
Blottisham frowned.
“Why is that excellent?”
“Because for once you have reached the question before the answer.”
Miss Stray poured herself some coffee.
“And perhaps that is where an interpersonal self begins.”
Blottisham looked at the coffee machine.
“Does this mean the machine and I have a relationship?”
Quillibrace sighed.
“Only if it remembers how many coffees you have had.”
Blottisham looked at his cup.
“Then it knows me better than either of you.”
There was a long silence.
Miss Stray began to laugh.
Quillibrace closed his book.
“I believe we have just discovered the limits of philosophy.”
Blottisham stood up.
“No. We have discovered that the coffee machine has acquired a character.”
He pressed the button.
“It disappoints me every morning.”
And, for reasons none of them could quite explain, that suddenly seemed like a much more interesting statement than it had been five minutes earlier.
