Features: Modal logic is an important branch of logic and a special form of logical wisdom. This book introduces an overview of the development of modal logic and the basic content of traditional modal logic. It distinguishes between objective modality and subjective modality, logical modality and non-logical modality, deontic modality and epistemic modality, narrow modalities and broad modalities. It particularly provides a detailed introduction to the possible world semantics theory of alethic modality, the types of propositions, and valid inference forms. Additionally, it covers deontic logic (normative logic), temporal logic, and the basic theories of modal propositional logic calculi. The greatest feature of this book is its accessibility, using numerous examples to explain complex modal logic.
