Gist of Idea
What are the ontological grounds for grouping possibilia into worlds?

A Reaction
I do love people like Lycan who ask the simple commonsense questions about these highly sophisticated systems that students of philosophy are required to study. If a proposition is a 'set of worlds', understanding a proposition is beyond me.
