The Power of Critical Thinking: Effective Reasoning About Ordinary and Extraordinary Claims, Third Edition, presents the broadest range of tools for today's critical thinking students to apply in any arena, from everyday life to academia, and from science to the media. It explores the essentials of critical reasoning, argumentation, logic, and argumentative essay writing while also incorporating important topics that most other texts leave out, such as "inference to the best explanation," scientific reasoning, evidence and authority, visual reasoning, and obstacles to critical thinking. The Power of Critical Thinking, Third Edition, integrates many pedagogical features, including hundreds of diverse exercises, examples, and illustrations; text boxes that apply critical thinking to student experience; step-by-step guidelines for evaluating claims, arguments, and explanations; a glossary of important terms; many reminders, summaries, and review notes; and five progressive, stand-alone writing modules interspersed throughout the text. Written in a student-friendly style and enhanced by humor, this text is ideal for courses in critical thinking, introduction to logic, informal logic, argumentative writing, and introduction to argumentation. New to the Third Edition: * Six new "Essays for Evaluation" (three pairs arranged in a pro/con format, each pair debating a single issue) * An expanded Chapter 11 on moral reasoning * New, more instructive photos that encourage critical thinking about visual elements * More guidance on doing research and judging sources * A revised text box program that includes "Newsmakers" and "From the Web" in addition to "For Further Thought" * Updated pop culture and political references and examples--many ripped from the headlines or drawn from everyday life The Power of Critical Thinking, Third Edition, is supplemented by an Instructor's Manual with Computerized Test Bank (available both in print and on a CD) and a Companion Website at www.oup.com/us/criticalthinking that includes instructor resources and a student study guide.
