Mr Blottisham was examining a newspaper article about a scientific discovery when Professor Quillibrace entered the Senior Common Room.
“An interesting case,” Blottisham announced. “A researcher has developed a new theory with the assistance of an AI system. Naturally, the question has arisen as to who deserves the credit.”
“Why naturally?” asked Miss Elowen Stray, looking up from her book.
“Because someone must have had the idea. We need to establish whether it belongs to the researcher or to the machine.”
Quillibrace took his customary chair. “You seem determined to settle the question of ownership before establishing what happened.”
“I am proposing that we begin with the facts. The researcher supplied a question; the machine supplied a suggestion; the researcher developed it into a theory. Surely we can identify the source of each contribution.”
“Certainly,” said Elowen. “But suppose the researcher had never thought to ask that question without an earlier conversation with a colleague. Suppose the machine's suggestion was intelligible only because of the researcher's training, and the theory emerged when the researcher connected the suggestion with an experimental result. Which contribution would you identify as the origin of the theory?”
“The earliest one, obviously.”
“And if the colleague's suggestion had depended on a paper written by someone else?”
Blottisham looked impatient. “We cannot trace everything back to the beginning of the universe.”
“No,” said Quillibrace. “But we need not trace everything back to the beginning of the universe to recognise that an idea's emergence may depend on more than one originating act.”
Blottisham folded the newspaper.
“I begin to suspect that you wish to abolish origins.”
“Not at all,” said Elowen. “We wish to understand what an origin explains, and what it leaves unexplained.”
She drew a sheet of paper towards her.
“Consider a conversation. One person proposes an idea; another questions it. The first revises the proposal. The second notices a consequence neither had considered. Their exchange produces a thought that was not present in either contribution as originally made.”
“Then the origin of the thought was the conversation,” Blottisham replied triumphantly.
“Perhaps we can say that the conversation was essential to its emergence. But what made that conversation possible? Their prior knowledge, their purposes, the language they shared, the questions they were pursuing, and the circumstances in which they met. We could continue identifying conditions indefinitely. The important point is not to find the earliest item in the sequence, but to explain how the relations among them made this thought possible.”
Quillibrace nodded. “An origin can identify a point from which we begin a history. It does not, by itself, explain the process through which something came into being.”
Blottisham considered this.
“Yet historians routinely identify origins.”
“Of course,” said Quillibrace. “The question is what they mean by them. The origin of a war, for example, might be assigned to a particular event. But that event does not explain the war without the circumstances, tensions and decisions that made it consequential.”
“War is a different matter.”
“Only if you believe that ideas emerge without circumstances, tensions or decisions.”
Blottisham ignored this.
“Let us return to artificial intelligence. Surely there is a difference between an idea generated by a human and one generated by a machine.”
“Certainly,” Elowen replied. “Their capacities and histories differ. We may need to know how each contributed, what each could do, and who bears responsibility for the resulting work. But identifying those differences does not settle how the idea emerged through their interaction.”
“Then what does?”
“The relations that made the interaction productive.”
Blottisham frowned. “You speak as though relations were independent entities, moving ideas about between participants.”
“No,” said Elowen. “Relations are not additional objects that we must insert between the participants. They are part of what we need to understand about the participants' activity. A suggestion can have different consequences depending on who encounters it, what they already know, and what they are trying to accomplish.”
“Which means,” said Quillibrace, “that the same contribution can participate in different outcomes under different conditions.”
Blottisham looked at the newspaper again.
“I suppose the researcher might have ignored the machine's suggestion.”
“Indeed,” said Elowen.
“Or misunderstood it.”
“Certainly.”
“Or used it to develop an entirely different idea.”
“Precisely.”
Blottisham seemed momentarily pleased. “Then the researcher remains the true originator.”
“Why?” Elowen asked. “Because the researcher could have acted differently? The machine's contribution could also have been different. Neither fact explains the actual outcome on its own.”
“Someone must be responsible for what happens.”
“Responsibility is not the same as origination,” said Quillibrace. “The researcher may be responsible for checking the evidence, judging the argument and reporting the use of AI. Those obligations remain even if the idea emerged through a process involving many contributions.”
Blottisham appeared reluctant to surrender this distinction.
“So we may have to distinguish the source of an idea, the process through which it emerges, and the person responsible for what is done with it?”
“A promising beginning,” said Quillibrace.
“I should like it recorded that I proposed the distinction.”
Elowen smiled. “We shall have to establish whether you originated it.”
Blottisham gave her a suspicious look.
“I see that this line of inquiry may become personally inconvenient.”
“It often does,” said Quillibrace, “when a general principle is applied to its proponent.”
Blottisham rose and walked towards the window.
“Nevertheless, there must be a point at which an idea becomes an idea. Before that point, it does not exist. After it, it does.”
Elowen joined him.
“Perhaps. But even if we could identify that point, would it explain why the idea emerged there, in that form, rather than somewhere else or in another form?”
Blottisham watched a gardener moving a wheelbarrow across the lawn.
“The gardener planted a tree,” he said. “We know where the tree came from.”
“Do we know how the tree came to grow?” Elowen asked. “We know something about its seed, the soil, the water, the light and the conditions of its growth. The seed matters, but it does not grow in isolation.”
“Are you comparing ideas to trees?”
“Only in one respect. The existence of a beginning does not make the conditions of becoming irrelevant.”
Quillibrace rose.
“Perhaps the difficulty lies in our expectation that an explanation must terminate at an origin. We look for a point where the question can stop. But sometimes the more useful question is how the relations among things make a particular outcome possible.”
Blottisham returned to his chair.
“And what would you call a history that did not terminate at an origin?”
“A history of emergence,” said Elowen.
Blottisham thought about this.
“It sounds suspiciously like a history that refuses to finish.”
“Not at all,” said Quillibrace. “An explanation may be complete enough for its purpose without identifying a single first cause. We need to know which relations matter to the phenomenon under investigation. That is a demanding task, not an excuse to avoid conclusions.”
Blottisham took up the newspaper once more.
“I shall concede that the origin of an idea does not explain everything about it. But I retain the right to ask who thought of it first.”
“Of course,” said Elowen. “The question remains useful. It simply need not be the only question we ask.”
“And if we discover how an idea emerged?”
“Then we may understand not only how that idea came into being, but something about the conditions under which other ideas might emerge.”
Blottisham looked up sharply.
“Other ideas? You mean the explanation of one idea might help us discover how to produce another?”
“Or help us recognise the conditions that make one possible,” said Elowen.
Quillibrace returned to his book.
“Mr Blottisham, I believe you have finally moved beyond the origin of ideas.”
Blottisham straightened his waistcoat.
“Not at all. I have merely expanded the jurisdiction of the origin.”
Miss Stray laughed.
And for once, Quillibrace allowed the matter to rest.
