Overview

This revised and considerably expanded 2nd edition brings together a wide range of topics, including modal, tense, conditional, intuitionist, many-valued, paraconsistent, relevant, and fuzzy logics.

Part 1: Propositional Logic

Part 1, on propositional logic, is the old Introduction, but contains much new material.

Part 2: Quantification and Identity

Part 2 is entirely new, and covers quantification and identity for all the logics in Part 1.

Unified Theme

The material is unified by the underlying theme of world semantics.

Explanation and Relevance

All of the topics are explained clearly using devices such as tableau proofs, and their relation to current philosophical issues and debates are discussed.

Target Audience

Students with a basic understanding of classical logic will find this book an invaluable introduction to an area that has become of central importance in both logic and philosophy. It will also interest people working in mathematics and computer science who wish to know about the area.
