In classical and many quantum interpretations, measurement is treated as a window: a means by which an observer gains access to pre-existing properties of an independently existing system.
In relational ontology, this view is inverted.
Measurement does not reveal a property. It constitutes a phenomenon.
There is no pregiven state lying in wait, only a field of potential that becomes partially resolved — and only from a particular perspective — when a cut is enacted within the system.
1. The Classical Assumption: Observation as Discovery
The classical metaphysic treats measurement as:
-
Passive observation of an independently defined system,
-
Extraction of objective properties,
-
A neutral interface between observer and world.
This assumption survives in quantum theory through concepts like “collapse” and even in hidden variable models like Bohmian mechanics, where the measurement is merely a means of uncovering what was already there.
Relationally, this picture is untenable.
2. The Cut: Measurement as Ontological Act
Relational ontology reframes measurement as a cut in a system of potential.
Measurement is not a passive reading of what is, but an active partitioning of what can be.
The “cut”:
-
Actualises a specific coherence from within the field,
-
Foregrounds certain relations while excluding others,
-
Makes possible a phenomenon — a construed experience — not a revealed entity.
Measurement is thus constitutive, not merely descriptive.
3. Measurement and Coherence
From this perspective:
-
What is measured is not an object, but a punctualised coherence in the field,
-
The apparatus does not detect a thing; it participates in the organisation of constraint that enables the phenomenon,
-
The outcome is not a truth about the system, but a perspectival actualisation within it.
This accounts for the dependence of outcomes on measurement configurations — a feature often called “contextuality” in quantum theory.
4. No Pre-Measurement Reality
The idea of a property existing before measurement is a holdover from substance metaphysics.
In a relational system:
-
There is no “value” of a quantum property until the system is constrained in such a way that a value is constituted,
-
Different cuts produce different actualisations — not different readings of the same underlying state,
-
Reality does not exist in full before observation; it is co-constituted through systemic perspective.
This is not idealism or solipsism — it is a commitment to relation over substance, configuration over intrinsic property.
5. The Apparatus as Participant
In this light, the measuring device is not external to the system. It:
-
Embeds constraints into the relational field,
-
Narrows the space of potential,
-
Enables a specific mode of resolution.
There is no hard boundary between “observer” and “observed.” The measurement apparatus is a relational node — one part of a wider field organising itself under constraint.
Closing
Measurement, then, is not the point where knowledge intersects with reality. It is the moment when potential is selectively resolved into a perspectival phenomenon.
There is no quantum world “behind” the measurement.There is only the field — and the cut we make in it.
In the next post, we’ll explore how probability emerges in this model — not as uncertainty about hidden values, but as a measure of how constrained potential actualises across repeated construals.
