An Introduction to Philosophical Logic is a popular mainstay for students taking courses in philosophical logic and the philosophy of language. Covering some of the most central topics in philosophy - the proposition, theories of truth, existence, meaning and reference, realism and anti-realism - it aims to be an accessible guide to philosophical logic. This new edition keeps the same successful format, with each chapter providing a self-contained introduction to the topic it discusses, rewritten to include updated information. The author has also revised his concluding chapter and completely updated the bibliography.
