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.

Famous quotes containing the word term:
“Be near me when I fade away,
To point the term of human strife,
And on the low dark verge of life
The twilight of eternal day.”
—Alfred Tennyson (1809–1892)
