What is the primary difference between classical logic and modal logic?
AnswerClick to flip back
A
Classical logic deals with statements that are either true or false, while modal logic deals with statements that are possibly true or possibly false.
💡 Explanation:
Modal logic is an extension of classical logic that allows us to reason about the possibility and necessity of statements. In modal logic, we can say that a statement is possible if there is at least one possible world in which it is true, and we can say that a statement is necessary if it is true in all possible worlds.
