The Term possible World
The term goes back to Leibniz's theory of possible worlds, used to analyse necessity, possibility, and similar modal notions. In short: the actual world is regarded as merely one among an infinite set of logically possible worlds, some "nearer" to the actual world and some more remote. A proposition is necessary if it is true in all possible worlds, and possible if it is true in at least one.

“No—is a term very frequently employed by the fair, when they mean everything else but a negative. Their yes is always yes; but their no is not always no.”
