Systems, Instantiation, and the Grammar of Constraint –1: Instantiation, Constraint, and Autonomous Systems

When we talk about systems—biological, social, or semiotic—there is a temptation to imagine them as “things” out there in the world, with fixed boundaries, interacting like billiard balls. Relational ontology invites us to do something radically different: to start with instantiation, not with the system itself.

Instantiation is the event. The only thing that actually happens. In any instantiation, multiple autonomous systems—each with its own potential, its own “space of possibility”—come together. But they do not merge. They do not collapse into a single system. They merely co-actualise under mutual constraint.

This is the fundamental move: systems are autonomous, instantiation is the event of their interaction, and constraint is the glue that allows them to co-occur without annihilating their independence.

1. Autonomous Systems: Three Domains

To make this concrete, consider three broad domains:

1. Biological systems – the value-driven selection dynamics that shape neural, physiological, and behavioural activity.
2. Social systems – the configurations of coordination and value that structure interactions between agents.
3. Semiotic systems – the stratified architectures of meaning, encompassing context and language.

Each domain is internally coherent and autonomous, but in instantiation, they are mutually constrained. No system dictates another. No hierarchy enforces itself. Instantiation is a field of interaction, not a container.

2. Constraint as the Principle of Co-Actualisation

Constraint is subtle but decisive. It is not a rule imposed from above, nor a law in the Newtonian sense. Instead, it is the space of compatibility that allows multiple autonomous selections to co-occur in the same event.

• In a biological system, neural pathways select viable behaviours.
• In a social system, coordination patterns select viable interactions.
• In a semiotic system, registers and situation types select viable meaning configurations.

All of these selections happen together, constrained by the same event—but none of them contains the others. Constraint is the relational principle that makes co-actualisation possible.

3. Why Start with Instantiation?

Why start here rather than with the system? Because systems are inferred. They are potentials, spaces of constraint, stabilised over histories of instantiation. To understand what a system is, you must first look at the events in which it participates.

Instantiation is primary. System is secondary, inferred from regularities across instantiations.

This reframes everything: stability, identity, and even “meaning” are effects of repeated co-actualisation under constraint, not pre-existing objects.

4. Looking Ahead

In this series, we will progressively reveal:

• How subpotentials arise as stabilised distributions over instantiations.
• How systems emerge as constraint structures inferred from these distributions.
• How semiotic stratification—context and language—fits into this relational picture.
• How inference itself is an instantiation-level operation that stabilises systems without requiring a meta-level observer.

By the end, we will have a fully self-consistent ontology: autonomous systems, co-actualisation, stabilised distributions, and recursive constraint loops. Nothing floats outside instantiation; everything arises relationally.
