Language, Knowledge, and Metaphysics (Philosophy) Book

A very helpful and well-written tour of the characteristics and applications of the modal logics. The reader will want to be familiar with the basics of propositional and predicate symbolic logic. There are plenty of examples in order to practice with the deduction rules, and the philosophical section serves as an excellent and accessible primer to the extension of modal logic into a variety of fields such as epistemology, ethics, and dynamics. If you are grounded in basic logic and are looking to extend into the modal world, this is a great resource.
