Full Idea

Non-actual states of affairs are possible if there actually was a substance capable of initiating a causal chain, perhaps non-deterministic, that could lead to the state of affairs that we claim is possible.

Gist of Idea

A state of affairs is only possible if there has been an actual substance to initiate it
