The Power of Critical Thinking: Effective Reasoning About Ordinary and Extraordinary Claims 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 text 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; and many reminders, summaries, and review notes. New to this editionNew sections on topics suggested by reviewers - The coverage now includes more discussion of legal reasoning, rhetorical ploys, informal fallacies, probability and statistics, and necessary and sufficient conditions.New Essays for Analysis - Nine essays, several of them by women authors, have been added to the collection of "Essays for Evaluation" in Appendix A (the total remains at twenty-one), each article accompanied by writing prompts and linked to writing assignments in every chapter. Four pairs of essays are arranged in a pro/con format, each pair debating a single issue. New topics include homosexuality, feminists and pornography, adultery, airport security screenings, women in Afghanistan, Islamic extremists and free speech, and fear of vaccines.New text boxes on current topics. The division of labor for the text boxes is the same, but some of the content is new. The three types of boxes are "Newsmakers" (discussions of current events and issues in the media illustrating a principle of critical thinking, ending with questions meant to encourage critical thought); "From the Web" (boxes concentrating on a lesson about critical thinking but drawing their material from websites and blogs); and "Further Thought" (informative boxes, designed to cover interesting supplementary material not discussed in the main text).The chapter objectives now correspond to the point-by-point summary at the end of each chapter.Important Clarifications - The following discussions are now even clearer: scientific conservatism in theory choice, the relationship between enumerative induction and statistical syllogisms, and informal fallacies (the latter are given further treatment in an explanatory fallacies chart on the inside front cover).Some new discussions: the straw man fallacy, biased opinion polls, dishonest political discourse, and gut reactions and intuitions.
