possible world semantics

Possible world semantics is a way of understanding meaning and truth by considering different hypothetical scenarios or "worlds." Instead of just evaluating whether a statement is true here and now, it asks whether the statement would be true in other potential situations. This approach helps analyze concepts like necessity, possibility, and belief by comparing how things are in the actual world to how they might be in other possible worlds. It provides a structured framework for discussing what could be true, what must be true, or what might be true under different circumstances.
