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 :-)
