Now significantly easier and more enjoyable for students to read, this most complete and authoritative treatment of introductory logic—both deductive and inductive, classical and modern—prepares students to understand, recognize, and apply classical syllogistic logic and the more powerful techniques of modern symbolic logic. It explains all concepts and techniques clearly, accurately, and thoroughly, bringing them to life using a wealth of real-life examples of lively arguments and explanations. These examples are drawn from political speeches, classics of philosophy (ancient and modern), newspaper and magazine articles, scientific reports, writings on economics, great 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.
