Principles of World Theory say, more or less, that: - a proposition (whatever) is *necessary* iff it is true in all worlds; - a proposition (whatever) is *possible* iff there is some world in which it is true; - there is only one *actual* world; - there are propositions which are true at the *actual* world; - there are propositions which are not true at the *actual* world, but they are true at some *non-actual* *possible* world. It is not much. But, in any case, we must start from these points :-)
