This volume provides a comprehensive collection of classic and contemporary readings in the philosophy of logic. The selections include some of the most important, technically exact, yet lucid and readable expositions of central concepts and controversies in philosophical logic. Areas of coverage include classical logic; truth; propositions and meaning; quantifiers and quantificational theory; validity, inference, and entailment; and modality, intensionality, and propositional attitude. Since the articles are written from a variety of perspectives the reader is able to critically assess the background and current trends in philosophical applications of symbolic logic. The volume also examines the limitations of classical and nonstandard logics.
