Readiness as Categorial Grammar: Inclination, Ability, and the Architecture of Potential: 6 Actualisation as Morphism Selection: The Event as a Cut in Readiness

Up to this point, we have construed potential as structured in three complementary ways:

• Inclination — endogenous morphism-pressure

• Ability — exogenous morphism-coherence

• Readiness — the functorial mapping between the two

This gives us a fully relational grammar of potential: an organised topology of what could happen, and the mappings that make those potentials mutually intelligible.

But nothing has happened yet.

Potential, however structured, is not event.

Potential is theory — the system — a space of construals not yet cut into the particular.

Actualisation is the perspectival incision where a morphism in the functorially mapped potential is selected from among the many that could have been. It is not a process, nor a temporal unfolding. It is the morphism selection cut, the perspectival reconfiguration that constitutes an event.

In categorical terms:

Actualisation is the selection of a specific morphism in the readiness-structured potential.

In relational-ontological terms:

Actualisation is the perspectival cut through readiness that brings one morphism into focus as the event.

This post explores that cut.

1. The Landscape Before the Cut

Before the cut, we have:

1. A category of inclination — internal morphism-pressure

2. A category of ability — external morphism-coherence

3. A functor of readiness — the structured mapping aligning the two

This readiness-functor defines:

• Which morphisms are internally coherent

• Which morphisms are externally permissible

• And how these two strata correspond

But no single morphism is yet selected.

The readiness-functor defines the space of actualisable morphisms, but it does not choose among them. It shows what could be actualised without yet actualising anything.

Thus:

Actualisation is not encoded in readiness.

It is the cut through readiness.

2. Actualisation as Morphism Selection

A morphism in readiness is just one among many: a structurally sanctioned pathway of transition. Actualisation is the selection of one such morphism as the morphism that becomes the event.

This selection is not motivated by an internal force nor triggered by an external cause; both frameworks would violate our relational ontology. Instead:

Actualisation is a perspectival shift that redefines the system through a chosen morphism.

Selection is not decision; it is reconfiguration. It is the constitutive move that turns:

• A network of inclinations

• A field of abilities

• A functor of readiness

into:

• A single morphism that now counts as the event.

This is the cut.

In category theory, this appears innocently: choosing a particular arrow from object A to object B. But in relational ontology, this selection redefines what object A and object B now are, because:

• The system is the theory of its possible instances

• The event is the instantiation of that theory through a perspectival cut

• Choosing a morphism reorganises the theory of objects and morphisms around that selection

Thus:

Actualisation is not just the choosing of a morphism;

it is the reconfiguration of potential around that choice.

3. The Event as a Cut in Readiness

What makes the event “an event” is not that something changed; it is that a cut was made.

A cut is the perspectival act of carving a single morphism out of the readiness-structured potential and constraining the system to that selection. It creates:

• A before that was not yet distinguished

• An after that reconfigures the space of potential

• A this that now stands as the event

The event is the morphism selected; the cut is the construal.

The event is the shape; the cut is the shift of perspective that gives it actuality.

A morphism may exist in readiness “in theory,” but it becomes an event only when construed as the selected transition. Readiness provides the full structural space of possible morphisms. The cut selects a single one, and in doing so, reorients the entire readiness-structure.

Thus:

• The functor gives the grammar of what could happen

• The cut produces the event of what did happen

---

4. Actualisation and the Collapse of Alternative Morphisms

Once a morphism is selected, all alternative morphisms are no longer “unactualised possibilities” in a metaphysical sense. They are simply other construals of potential, irrelevant from the new perspective constituted by the cut.

There is no metaphysical collapse.

There is only a perspectival shift that now treats the selected morphism as the constitutive actualisation.

The rest remain potential — but potential relative to a new readiness configuration.

This is crucial:

The cut reorganises readiness.

The event is not added to the system; the system is re-theorised around the event.

This is why actualisation is not a process.

The cut:

• Selects

• Reconfigures

• Redefines

rather than unfolds or causes.

---

5. Actualisation as Re-Theorisation

Since the system is the theory of the instance, and the event is an instance cut from the system, actualisation is the move that forces a reevaluation of the system itself.

After the cut, the system is no longer the same theory.

The readiness-functor must be re-evaluated relative to the selected morphism.

Inclinations and abilities may shift accordingly.

Thus, the event does not “occur in” a system.

The event redefines the system.

Actualisation is the cut that produces the new system-event pairing.

---

6. Summary: The Event as the Functorially-Constrained Cut

We can summarise as follows:

• Potential is structured by inclination, ability, and readiness

• Readiness functorially maps internal and external potentials

• Actualisation is the selection of a specific morphism within readiness

• The event is that selected morphism, construed as the particular

• The cut is the perspectival shift that constitutes the event

• The system is re-theorised relative to that cut

Thus:

Actualisation is morphism selection;

event is the selected morphism;

the cut is the perspectival act that binds them.

This completes the relational-ontological account of actualisation in functorial terms.
