Full Idea
Possible worlds ontology appears to be plentiful enough to allow every philosophical theory to be true in some world or other, and that is why I cannot consider it an ontologically serious theory. It admits everything and forbids nothing
Gist of Idea
Every philosophical theory must be true in some possible world, so the ontology is hopeless

A Reaction
Nice. Be careful what you wish for. The theory would have to be consistent (unless we also accept impossible worlds).
