"Potential is never empty; it waits only for the cut that brings an instance into view."
In this series, we explore how structured potential gives rise to instances across multiple domains: from formal systems to quantum theory. The wavepacket, Gödel sentences, and measurement outcomes are all manifestations of the same underlying pattern: potential structured as a theory of possible instances, actualised through relational cuts. By following this pattern, we uncover a unifying architecture that connects logic, mathematics, physics, and ontology itself.
An orientation to the series
In the earlier series on Gödel and relational ontology, we arrived at a rather striking conclusion: formal systems do not merely contain truths; they organise spaces of potential truths. Gödel’s incompleteness theorem shows that no such space can be completely resolved from within itself. There will always be statements whose status lies at the boundary between potential and instance.
The moment a Gödel sentence is recognised as true, a relational cut occurs. The sentence passes from the domain of possible derivations within a system to the domain of actual theorems within an expanded one.
That observation raises an intriguing question.
If relational ontology correctly describes the structure of formal systems, might similar structures appear elsewhere?
Quantum theory turns out to provide a fascinating test case.
A theory written in the language of potential
The mathematics of quantum mechanics is unusual among physical theories. Instead of describing what is, it describes what may become.
The central object of the theory — the wavepacket — does not represent an event. It represents a structured space of possible events. Schrödinger evolution describes how this space of possibilities changes under interaction. Measurement produces one actual event from that space.
Physicists have long regarded this feature as mysterious. It gives rise to the notorious “measurement problem”, the puzzle of why a smooth wave suddenly appears to collapse into a single outcome.
From the perspective of relational ontology, however, the structure should look oddly familiar.
It closely resembles the relation between a system and its instances.
The recurring architecture
Across a surprising range of domains we encounter the same underlying pattern.
A structured domain of possibilities generates instances through some form of selection or derivation:
| Domain | Potential | Instance |
|---|---|---|
| Language | system | text |
| Logic | formal system | theorem |
| Mathematics | axioms | proof |
| Quantum theory | wavepacket | measurement event |
In each case the potential domain describes a theory of possible instances. The instances themselves emerge through a boundary operation that connects potential to event.
In relational ontology this boundary is called the relational cut.
Once this pattern is recognised, the conceptual puzzles of quantum mechanics begin to look less exotic. The wavepacket is simply a particularly explicit mathematical representation of structured potential.
What this series will explore
The posts that follow pursue this idea in a systematic way.
First, we reconsider the quantum wavepacket itself. Instead of treating it as a physical wave or probability distribution, we interpret it as a formal description of a theory of possible instances associated with a physical configuration.
Second, we place the wavepacket on the cline of instantiation, the perspectival continuum between maximal potential and concrete event.
Third, we show how the transformations described by Schrödinger’s equation can be understood relationally — as morphisms that transform one potential structure into another.
Fourth, we examine the moment of measurement as a relational cut connecting two domains: the category of potential states and the category of actual events.
Finally, we return to Gödel’s incompleteness theorem and show that it exhibits a strikingly similar structure. Gödel sentences occupy the boundary where potential exceeds the expressive capacity of the system that describes it — precisely the boundary where relational cuts occur.
Why this matters
The goal of this series is not to offer a new interpretation of quantum mechanics in the usual sense.
Rather, it is to show that quantum theory may already be describing something far more general than the behaviour of microscopic particles.
It may be describing the structure of potential itself.
Seen in this light, the wavepacket is not a strange physical entity inhabiting Hilbert space. It is a mathematical representation of a theory of possible instances. Measurement is not a mysterious collapse but the ordinary operation through which instances are actualised from structured potential.
Quantum mechanics therefore provides a rare and illuminating window into a principle that relational ontology proposes to be universal:
the world is organised as spaces of possibility whose instances emerge through relational cuts.
The posts that follow explore what happens when we take that idea seriously.
