A Conversation in the Senior Common Room (Where Blottisham Attempts to Improve Perception by Comparing It to Reality Itself, and Quillibrace Objects to the Entire Setup)
Mr Blottisham is standing by the window in the manner of someone quietly disappointed with the universe’s refusal to present itself more faithfully. He is gesturing faintly at the garden, as though it has personally let him down.
Blottisham:
It’s fairly straightforward, surely. The question is whether what we perceive actually matches what’s out there. If not, then perception is at least somewhat unreliable—perhaps even systematically so.
Professor Quillibrace looks up from a page he has not yet written on.
Quillibrace:
You’ve smuggled in a comparison space that cannot be occupied.
Blottisham (briskly):
I don’t think it’s smuggled. It’s implied. We experience the world, and then we ask whether that experience corresponds to how the world is in itself.
Quillibrace:
No. You are not “experiencing the world and then comparing it to how it is in itself.” You are already operating within construal conditions that determine what “world,” “experience,” and “is” can mean.
Miss Stray tilts her head slightly, as if listening not to the argument but to its structural footing.
Stray:
You’re both assuming there is a position from which the comparison is made.
Blottisham waves this away gently, as if it were an atmospheric condition.
Blottisham:
Well, yes—some vantage point. Otherwise how would we ever notice distortion? Illusions, hallucinations, measurement error—these all suggest a gap between appearance and reality.
Quillibrace closes the page entirely now, which is never a good sign for Blottisham.
Quillibrace:
They suggest variation within constrained systems of construal. Not a gap between two independently accessible domains.
Blottisham (leaning in, warming to his theme):
But surely there is a difference between how things seem and how they actually are. That distinction is doing real work.
Quillibrace:
It is doing grammatical work, not ontological work.
There is a pause in which Blottisham appears to consider whether grammar can be trusted at all, and decides—reluctantly—that it probably can.
Miss Stray speaks more softly, as if describing something already in motion.
Stray:
“Reality as it really is” is doing something more specific than it appears. It’s constructing a second space—an unconstrued version of reality—that you then compare perception against.
Blottisham brightens slightly.
Blottisham:
Exactly. That’s the point. Is perception aligned with that underlying reality or not?
Quillibrace looks at him with the expression of someone watching a very neat staircase lead into empty air.
Quillibrace:
There is no “underlying reality” in that sense available outside construal. You are treating construal as optional decoration layered over a fully formed world.
Blottisham:
But surely the world is there whether we perceive it correctly or not.
Quillibrace:
Yes. But “there” is already a relationally specified position within a system of construal. You are not comparing perception to an unconstrued world. You are comparing one construal to another, under different constraints.
Miss Stray interjects, almost gently.
Stray:
The symmetry you’re assuming—appearance on one side, reality on the other—is itself produced by the act of framing. It is not something you discover. It’s something the question installs.
Blottisham pauses. This is the moment, as Quillibrace would later note, where he briefly suspects that the floor might not be where he thought it was.
Blottisham:
So you’re saying there is no sense in which perception can be mistaken about reality?
Quillibrace immediately corrects him.
Quillibrace:
No. I am saying “mistake” operates within constraints of construal, not across a comparison with an unconstrued totality.
Stray:
Misalignment is real. But it is internal to relational systems, not evidence of access to a separate, pure domain called “reality as it really is.”
Blottisham frowns, not entirely dissatisfied, but clearly missing the clean opposition he had hoped to defend.
Blottisham:
That does make things less… dramatic.
Quillibrace returns to his earlier page as though concluding the matter.
Quillibrace:
Drama is not a criterion of explanatory adequacy.
Stray, quietly:
Stray:
Nor is “reality-in-itself” a stable comparison term.
A pause settles over the room. Outside, the garden continues to be neither distorted nor revealed, simply differently construed depending on where one stands and what one is trying to make it do.
Blottisham, after a moment:
Blottisham:
So we never actually get outside perception to check?
Quillibrace, without looking up:
Quillibrace:
You are always already inside the conditions that make checking possible.
Stray adds, almost as an afterthought:
Stray:
Which is why the idea of a checkable “outside” is so persistent. It feels like a solution because it is generated by the same structure it is trying to escape.
Blottisham nods slowly, as though reluctantly accepting that his imagined inspection point has been withdrawn without permission.
Closing Observation (Stray, softly):
The question doesn’t fail because perception is unreliable. It fails because it assumes there is somewhere else—from which reliability could be assessed without perception already doing the assessing.
