An Introduction to Formal Logic
This is a highly accessible guide to the fundamental aims and basic elements of formal logic. Peter Smith introduces the reader to the languages of propositional and predicate logic, and then develops formal systems for evaluating arguments translated into these languages, concentrating on the easily comprehensible 'tree' method. His discussion is richly illustrated with worked examples and exercises, and also provides provides illuminating philosophical commentary. It will make an ideal text for a first logic course, and will provide a firm basis for further work in formal and philosophical logic.
