Coherence

It describes the state in which system behavior is consistent with the structural relationships that define it.

In a coherent system, actions taken by its parts do not undermine the conditions required for the system to function. This is not because conflict is absent, but because the interactions between parts are informed by their interdependence.

Coherence is therefore not a surface-level property. It is a structural condition that determines whether a system can sustain itself over time.

Coherence is often recognized through its absence.

When actions produce outcomes that contradict their intent, or when systems require continuous correction to maintain stability, incoherence is present.

When coherence increases, systems require less external control because their behavior aligns internally with the conditions that sustain them.

Coherence operates as a directional condition rather than a fixed state.

It increases as systems incorporate more accurate information about their structure and reorganize accordingly. At every scale, coherence determines whether systems stabilize, adapt, or degrade.

It is the baseline condition against which all system behavior can be evaluated.
