Philosophical logic refers to those areas of philosophy in which recognized methods of logic have traditionally been used to solve or advance the discussion of philosophical problems. Among these, Sybil Wolfram highlights the study of argument, meaning, and truth, while Colin McGinn presents identity, existence, predication, necessity and truth as the main topics of his book on the subject.
Philosophical logic also addresses extensions and alternatives to traditional, "classical" logic known as "non-classical" logics. John P. Burgess's Philosophical Logic introduces five types of non-classical logic, temporal logic, modal logic, conditional logic, relevantistic logic, and intuitionistic logic. These receive more attention in texts such as the Blackwell Companion to Philosophical Logic, or the multi-volume Handbook of Philosophical Logic edited by Dov M. Gabbay and Franz Guenthner.
