For undergraduate-level courses in Introduction to Logic. The most complete, authoritative treatment of introductory logic — both deductive and inductive, classical and modern — this text prepares students to understand, recognize, and apply classical syllogistic logic and the more powerful techniques of modern symbolic logic. All concepts and techniques are carefully and thoroughly explained and are brought to life through a wealth of real-life examples of lively arguments and explanations. These examples are drawn from political speeches, classics of philosophy (ancient and modern), scientific articles, writings on economics, literature, religious texts, and many recent writings on contemporary moral and social controversies familiar to students — all demonstrating the application of logical principles by serious writers and thinkers trying to solve real problems in a wide range of fields.
