Observing collections of events, is observing causality...<quoted text>
Causality is an induction - a conclusion drawn through induction by observing a constant correlation between prior events or conditions called causes, and subsequent ones call their effects.
Causality refers to relationships in the material world: This billiard ball caused that one to move.
Inductions are abstractions derived from observing collections of events and identifying their common or recurring qualities: billiard balls can cause inelastic collisions.
An event by its nature is causal.
