Full Idea
As far as I can tell, worlds need not be logically consistent. The only restriction on worlds is that they must be (in some sense) 'maximal' ways for things to be.
Gist of Idea
Possible worlds just have to be 'maximal', but they don't have to be consistent

A Reaction
The normal idea of a maximal model is that it must contain either p or ¬p, and not both, so I don't think I understand this thought, but I pass it on.
