This fifth edition of Critical Thinking by the noted logician Richard L. Epstein is practical, engaging, and easy to teach. Students enjoy and understand it because it is clear and has hundreds of examples using a cast of characters who reason as we do every day. More than 1,000 exercises lead students to be able to reason well in their courses and their lives. Essay writing lessons and visual writing lessons, using the cast of characters, teach students that first comes clear thinking and then comes clear writing. A complete and comprehensive Instructor's Manual makes the text easy to teach and grade. New to this edition: chapters on explanations and reasoning in the sciences. Also from the Advanced Reasoning Forum: An Introduction to Formal Logic and The Pocket Guide to Critical Thinking.
