Is randomness real? — Discuss

The room had entered what Blottisham later insisted was “an atmospherically suspicious level of philosophical stillness.”

Miss Stray was already by the window, watching the rain with the kind of attention that suggested she was not looking at it so much as tracking the conditions under which “rain” becomes a stable description.

Professor Quillibrace sat at the table, annotating a diagram titled Deterministic Systems and Apparent Chaos, though his marginalia increasingly resembled cautions rather than comments.

Blottisham arrived slightly out of breath, as if he had been delayed by the universe’s reluctance to coordinate itself properly.

“I’ve been thinking,” he announced, “about randomness.”

Miss Stray didn’t turn, but her attention sharpened.

Quillibrace closed the folder with deliberate care.

“That’s rarely a reassuring opening sentence,” he said.

Blottisham ignored this.

“The question is simple. Is randomness real?”

At this, Miss Stray finally spoke, still facing the window.

“That question arrives with more structure than it admits.”

Blottisham frowned.

“I’m just asking whether things can genuinely happen without cause.”

Quillibrace leaned back slightly.

“A deceptively innocent phrasing,” he said, “for something that quietly smuggles in half of metaphysics.”

Miss Stray turned now, not abruptly, but as though completing a relational adjustment.

“You’ve already treated randomness as an object,” she said. “Something that could either exist or fail to exist.”

Blottisham looked at her.

“Well… isn’t that what it is? Either the world contains randomness or it doesn’t?”

Miss Stray tilted her head.

“That assumes unpredictability must belong to the world rather than to the relation between world and construal.”

Quillibrace nodded once.

“The question ‘Is randomness real?’ appears to ask about ontology,” he said. “But it depends on a prior collapse: that limits of prediction are directly informative about being.”

Blottisham exhaled.

“That sounds like you’re saying our ignorance is misleading us.”

“Not quite,” said Miss Stray. “It’s more specific than ignorance.”

She gestured lightly toward the rain.

“It’s that you’re treating the boundary of your modelling capacity as if it were a boundary in reality itself.”

Quillibrace added:

“A reification of epistemic limits.”

Blottisham raised a hand.

“Can we slow down slightly? Because I’m fairly sure I just lost a piece of reality in that sentence.”

Miss Stray’s tone remained even.

“You didn’t lose reality. You misplaced the assumption that it must present itself at your chosen resolution.”

Quillibrace stood and moved to the board.

“The structure is fairly standard,” he said.

He wrote:

unpredictability → ignorance

ignorance → epistemic condition

epistemic condition → ontological property (illicit inference)

Blottisham squinted.

“So randomness is just… us failing to see enough detail?”

Miss Stray shook her head gently.

“That would still treat reality as fully determinate underneath,” she said. “Which is precisely the assumption doing the work here.”

Quillibrace interjected.

“There are multiple forms of indeterminacy being conflated.”

He ticked them off.

“Computational irreducibility. Sensitivity to initial conditions. Partial observability. Probabilistic modelling constraints.”

Blottisham sighed.

“And we call all of that ‘randomness’?”

“Conveniently,” said Miss Stray.

“Dangerously,” added Quillibrace.

Blottisham looked out at the rain.

“It feels random,” he said.

Miss Stray followed his gaze.

“It feels that way because the structure is distributed across scales that your immediate construal does not resolve.”

Quillibrace nodded.

“From within a local perspective, unresolved structure presents as indeterminacy.”

Blottisham frowned.

“So it’s not in the world… but it’s not just in us either?”

Miss Stray turned slightly toward him.

“It is in the relation,” she said. “Between system, constraint, and the level at which it is being construed.”

Quillibrace allowed a small pause.

“Randomness,” he said, “is not a property waiting in events. It is what appears when structured variability exceeds the resolution of a given modelling regime.”

Blottisham rubbed his forehead.

“That sounds like you’ve abolished randomness by redefining it very carefully.”

Miss Stray allowed a faint smile.

“Not abolished,” she said. “Relocated.”

Quillibrace added:

“From ontology to relational description.”

A silence followed, in which the rain continued behaving exactly as it had before, now slightly less committed to appearing metaphysically simple.

Blottisham finally said:

“So is randomness real or not?”

Quillibrace and Miss Stray exchanged a glance that suggested the question had not so much been answered as gently disassembled and reassembled elsewhere.

Quillibrace replied first.

“It depends what you are asking to be real.”

Miss Stray added:

“And at what level you are willing to let description stop pretending it is a property of things.”

Blottisham sighed.

“I feel like I’ve been given clarity and lost my question at the same time.”

Miss Stray looked back to the window.

“That is often the same event,” she said, “seen from different constraints.”

And the rain continued — neither random nor non-random — simply no longer willing to be reduced to a single description at a single scale.
