Modal Logic - An Introduction to its Syntax and Semantics torrent

In this text, a variety of modal logics at the sentential, first-order, and
second-order levels are developed with clarity, precision and philosophical
insight. All of the S1-S5 modal logics of Lewis and Langford, among others, are
constructed. A matrix, or many-valued semantics, for sentential modal logic is
formalized, and an important result that no finite matrix can characterize any
of the standard modal logics is proven. Exercises, some of which show
independence results, help to develop logical skills.
