Quantum mechanics does not look unstable when you examine what it actually does.
The instability appears elsewhere.
It appears when we try to decide what the theory is about.
And that is where a quieter, more structural problem emerges:
not a failure of physics, but a persistence of an inherited ontology that no longer fits comfortably with the science it accompanies.
1. The hidden frame: Galilean ontology
Much of modern scientific intuition still carries a background commitment to what can be called a broadly Galilean ontology.
It assumes that reality consists fundamentally of:
- determinate objects,
- possessing intrinsic properties,
- existing in space independently of observation,
- and remaining what they are regardless of interaction.
Science becomes a process of increasingly accurate description of pre-given reality.
This ontology is not “wrong” in any simple sense.
It is extraordinarily powerful.
It underwrites classical mechanics, engineering, and a vast range of stable macroscopic prediction.
But it is still an ontology.
And quantum mechanics begins to stress it in very specific ways.
2. The mismatch that produces “paradox”
Quantum mechanics does not directly contradict experimental practice.
It contradicts expectations about what must exist behind that practice.
For example:
- superposition appears to violate determinate statehood,
- measurement appears to disturb rather than reveal,
- entanglement appears to violate separability,
- and the double-slit experiment appears to destabilise object identity.
But each of these “problems” assumes something very specific:
that physical systems must already possess fully determinate properties prior to interaction.
That assumption is not produced by quantum theory.
It is inherited.
And it is here that the interpretive tension arises.
3. Instantiation and immanence: a different starting point
If we shift the ontological framing—drawing on ideas of immanence and instantiation—a different picture becomes available.
Instead of assuming:
objects come first, and relations follow,
we begin with:
relationally structured potential, within which determinate actuality is instantiated under constraint.
On this view:
- “states” are not pre-existing properties waiting to be revealed,
- they are actualisations within a structured field of possibility,
- “measurement” is not passive observation but a constrained relational event,
- “collapse” is not metaphysical mystery but stabilisation of one outcome among possible trajectories,
- and “objects” are durable patterns of instantiated stability across time.
This does not weaken physics.
It reframes what the physics is doing.
4. Why the quantum “anomalies” dissolve
From within a Galilean ontology, quantum mechanics looks like a series of paradoxes because it violates the expectation of pre-given determinacy.
From within an instantiation-based ontology, those same features become unsurprising.
Superposition is no longer “multiple contradictory states.”
It is unresolved systemic potential prior to constrained actualisation.
Measurement is no longer “collapse of a pre-existing state.”
It is participation in the production of a determinate outcome.
Entanglement is no longer “spooky action at a distance.”
It is evidence that separability is not fundamental but conditionally stabilised.
The anomalies do not disappear because the mathematics changes.
They disappear because the ontological expectations change.
5. The real issue: inherited metaphysical habits
The key claim is not that physics is confused.
It is that interpretation often remains bound to a metaphysical framework that quantum mechanics itself quietly undermines.
So the tension is not between:
- realism and anti-realism,
- or classical and quantum physics,
but between:
- a substance-based ontology of completed objects,and
- a relational ontology of instantiated determination.
The science remains intact either way.
What changes is how we are licensed to understand what it is doing.
6. Objecthood as an achievement, not a starting point
Once the instantiation perspective is taken seriously, a subtle inversion follows:
classical “objects” are no longer the ontological foundation of physics.
They become:
highly stable, repeatedly instantiated regimes of relational coordination.
That is why classical physics works so well.
It operates in domains where relational constraints produce extremely durable patterns of determinacy.
Quantum mechanics, by contrast, exposes the variability beneath those stabilisations.
Not as failure.
But as structure.
7. Closing shift
The deepest shift is not from certainty to uncertainty.
It is from:
reality as pre-completed structure
to:
reality as structured actualisation.
And once that shift is made, quantum mechanics no longer appears as a rupture in nature.
It appears as a pressure point in an inherited way of thinking about nature.
Conclusion
Quantum mechanics works.
The interpretive difficulty arises when we insist on reading it through an ontology designed for a different scale of stability.
The problem is not the science.
It is the expectation that reality must already be fully determinate prior to the relational processes through which determination is actually instantiated.
And once that expectation is released, many of the famous “quantum paradoxes” no longer demand resolution.
They simply mark the boundary of an older ontology.
