Critical Reasoning
Consider the terms vague, ambiguity and generality as they relate to our textbook reading for this week.
How are vagueness, ambiguity and generality used in politics or in law in order to achieve a desired outcome?
What are some examples of how this might be applied in your future career?
Include an example or two from current events that demonstrates the use of vagueness, ambiguity and generality.

Critical Thinking . . . Skills for the course. Skills for life.
More Engaging
Moore & Parker are known for fresh and lively writing. They rely on their own classroom experience and on feedback from instructors in getting the correct balance between explication and example.
Examples and exercises are drawn from today’s headlines. Students learn to apply critical thinking skills to situations in a wide variety of areas: advertising, politics, the media, popular culture. I love the sense of humor of the authors, the very clear and elegant way they
make critical thinking come alive with visuals, exercises and stories. —Gary John, Richland College
[Before reading this chapter] most students don’t realize the extent of product
placement and other similar attempts at subtle manipulation. —Christian Blum, Bryant & Stratton, Buffalo
More Relevant
Moore & Parker spark student interest in skills that will serve them throughout their lives, making the study of critical thinking a meaningful endeavor.
Boxes show students how critical thinking skills are relevant to their day-to-day lives. Striking visuals in every chapter show students how images affect our judgment and shape our thinking.
The variety [in the exercises] was outstanding. [They] will provide ample opportunity for the students to put into practice the various
logical principles being discussed. —Ray Darr, Southern Illinois University
Page xvii
■
More Student Success
Moore & Parker provide a path to student success, making students active participants in their own learning while teaching skills they can apply in all their courses.
Learning objectives link to chapter sections and in turn to print and online activities, so that students can immediately assess their mastery of the learning objective.
■
■
Exercises are dispersed throughout most chapters, so that they link tightly with the concepts as they are presented. Students have access to over 2,000 exercises that provide practice in applying their skills.
Hands-on, practical, and one might say, even “patient” with the students’ learning as it emphatically repeats concepts and slowly progresses them step by
step through the process. —Patricia Baldwin, Pitt Community College
There are a lot of exercises, which provides nice flexibility. The . . . mix of
relatively easy and more challenging pieces . . . is useful in providing some flexibility for
working in class. —Dennis Weiss, York College of Pennsylvania

Changes to the 12th Edition
aving arrived at an even dozen editions, we still have our original goal constantly in mind: helping teach students to think and reason critically and make better decisions and making life a bit easier for instructors of critical
thinking courses. We invite both students and instructors to get in touch with us with any ideas they have that might help us pursue these goals.
As usual, this edition updates names and events in examples and exercises in the hope that they will be familiar to the current crop of students. As we’ve mentioned before, what to many of us instructors are recent events are obscure history to many new freshmen. Other changes are as follows.
CHAPTER-SPECIFIC CHANGES
Chapter 1 begins with a fuller accounting of what we take critical thinking to be. It also goes into a bit more depth regarding cognitive biases that affect our thinking. Chapter 2 contains a revised section on inference to the best explanation (IBE). Chapter 3 is somewhat leaner, but still makes a wealth of points about the important concepts of vagueness and generality and it contains a revised account of several types of definitions. Chapter 4 gets the usual updating here and there plus a new section on credibility in social media.

Chapter 5 gets updating, new photos, and a subsection on significant mention under the innuendo heading. Chapter 6 is left largely unchanged aside from some new examples and photos. Chapter 7 is also much the same as the previous version, although “fallacious” appeals have been changed to “mistaken” appeals; why use a word students have trouble spelling when there is one they don’t? Chapter 8 was new in the previous edition. It gets updated this time around, including a replacement of the section entitled “Overlooking False Positives” with an easier to understand “Faulty Inductive Conversion” section. Chapter 9 gets a bit of reformatting to make examples stand out more easily. Also, existential assumption gets its own subsection so it will be more difficult to miss.
Chapter 10 now makes the electrical circuit box a bit less distracting and adds a couple of new exercises to aid in learning to symbolize claims. But the biggest change from the previous edition is the reinsertion of a section that gives a briefer version of truth-functional arguments. This allows an instructor (like Moore) to deal quickly with this subject or (like Parker) to deal with it in much more detail by going on to the longer treatment that completes the chapter. Chapter 11 has the sections on analogies and generalizations fine-tuned, while the section on causal hypotheses remains in its previous pristine form. Chapter 12 has been left alone aside from a bit of updating of examples.

W Acknowledgments
e, Moore and Parker, feel about this textbook the way people usually feel about their children. It has been a wonderful thing to watch it grow up through these (now) dozen editions, although it has caused us the occasional
pain in the backside along the way. Those pains—often in the form of criticism in reviews and correspondence from adopters—have usually been growing pains, however, and they have contributed to the improvement of the book. We are pretty pleased with the book, as proud parents are wont to be, but we realize that there are always things—smaller and smaller things, we hope—that can be changed for the better. We hope this edition incorporates changes of just that sort. Many of them are listed below.
The online accompaniment to the text continues to expand and, we trust, become more and more useful to adopters and their students. The preceding pages briefly describe LearnSmart and Connect, the principal components of the online material. These programs promise help for the student and an easier and more productive time for the instructor. We hope you find they live up to this promise.
Having escaped from the mysterious clutches of Mark Georgiev, former KGB operative and our editor a couple of editions ago, we have been blessed by guidance this time around from the gentle hands of Penina Braffman, Brand Manager; Anthony McHugh, Product Developer; Jane Mohr, Content Project Manager; as well as Erin Guendelsberger, Reshmi Rajeesh, and the ansrsource team, Development Editors, who encourage us even when we don’t quite toe the McGraw-Hill line.
The guidance of the following reviewers of current and previous editions and others who have written to us has been invaluable:
Keith Abney, California Polytechnic State University, San Luis Obispo James Anderson, San Diego State University Benjamin Arah, Bowie State University Sheldon Bachus Patricia Baldwin, Pitt Community College Monique Bindra Tim Black, California State University, Northridge Charles Blatz, University of Toledo

Over the years, our Chico State colleague Anne Morrissey has given us more usable material than anybody else. She’s also given us more unusable material, but never mind. We’ve also had fine suggestions and examples from Curtis Peldo of Chico State and Butte College; Dan Barnett, also of Butte College, has helped in many ways over the years.
We thank colleagues at Chico State, who are ever ready with a suggestion, idea, or constructive criticism; in particular, Marcel Daguerre, Randy Larsen, Becky White, Wai-hung Wong, Zanja Yudell, and Greg Tropea, whose death in 2010 left us saddened beyond words. Greg was a dear friend whose deep wisdom and quiet insight contributed significantly to our thinking over the course of many years. We are also grateful to Bangs Tapscott, Linda Kaye Bomstad, Ann Bykerk-Kauffman, Sue Patterson, and Jeffrey Ridenour for contributions both archival and recent.
Last, and especially, we give thanks to two people who put up with us with patience, encouragement, and grace, Leah Blum and Marianne Moore.

N A Note to Our Colleagues
o surprise, reading a book (or taking a course) in critical thinking won’t make anyone a genius. It won’t tell you who to vote for or whether to believe in God or whether to contribute to the Humane Society, But it can, we hope, help
students tell whether a given reason for doing or not doing one of those things is a good reason. It can help them spot irrelevancies in a discussion, emotional appeals, empty rhetoric, and bogus argument. Other courses can do these things too, of course. But speaking generally, other courses are probably not focused so intensely on those things.
There are differences about how best to go about teaching critical thinking. One of us, Parker likes to emphasize formal logic. Moore, not quite so much. One thing Moore and Parker both agree on, and possibly so do many instructors, is that drill and practice are essential to improving students’ critical thinking ability. And one thing we have found is that technology can be helpful in this regard. The personalized digital reading experience of this text (called SmartBook) questions students as they read, and the credit they get depends on the proportion of the questions they answer correctly. (We instructors can also see how long they spent on a reading assignment.) Additionally, Connect, McGraw-Hill’s assignment and assessment platform through which SmartBook is accessed, gives us the means to put a whole lot of exercises online. And these two things enable us to do even more drilling in class.
If you don’t use Connect or LearnSmart, this text contains hundreds and hundreds and hundreds of exercises of the sort (we think) that can be applied directly to the world at large. And they are all answered in the Instructor’s Manual. The explanatory material found in the text is (we hope) both concise and fairly readable for even first-year university students.
If you use this text or the online peripherals, we would appreciate hearing from you. We both can be contacted through McGraw-Hill Education, or via the philosophy department at Chico State.

B About the Authors
rooke Moore and Richard Parker have taught philosophy at California State University, Chico, for almost as long as they can remember. Moore has been that university’s Outstanding Professor, and both he and Parker have received
top academic honors on their campus. Moore has seen several terms as department chair, and Parker has served as chair of the academic senate and dean of undergraduate education.
Moore has a bachelor’s degree in music from Antioch College and a PhD in philosophy from the University of Cincinnati; Parker did his undergraduate degree at the University of Arkansas and his PhD at the University of Washington, both in philosophy.
Moore has finally given up being the world’s most serious amateur volleyball player. He and Marianne share their house and life with Sparky, as cute a pup as you’ll ever see. He has never sold an automobile.
Parker gets around in a 1962 MG or on a Harley softail. He plays golf for fun, shoots pool for money, and plays guitar for a semiprofessional flamenco troupe. He lives with Djobi, a hundred-pound Doberman.
Moore and Parker have remained steadfast friends through it all. They are never mistaken for one another.

1 Don’t Believe Everything You Think
Students will learn to . . .
Define critical thinking Explain the role of beliefs and claims in critical thinking Identify issues in real-world situations Recognize an argument Define and identify the common cognitive biases that affect critical thinking Understand the terms “truth” and “knowledge” as used in this book
little before noon on December 14, 2015, a man wearing a black stocking cap, black gloves, and a green sweat shirt with a four-leaf clover and the words “Get Lucky” printed on the front entered the Sterling State Bank in
Rochester, Minnesota.* He demanded cash and gave the teller a note saying he was armed. Police officers arrived and followed the man’s tracks in the snow to the parking lot of a Comfort Inn nearby, but by then the man had driven off in a car.
The next day, a reporter from KIMT-TV had set up in front of the bank to
Page 2
update the story, and right then and there the same man tried to rob the same bank again. When the teller saw the man he yelled out, “That’s the robber!” and the reporter called the police. This time when the police followed the suspect’s footprints they spotted his vehicle and apprehended him.
Now, educators will disagree about what exactly critical thinking is, but there will be no disputing that, whatever it is, “Get Lucky” wasn’t doing it. First of all, robbing banks isn’t necessarily the best way to make a living. But if you insist on robbing a bank, then probably you don’t want to leave footprints to your car, and probably you don’t want to try to rob the bank when a TV crew is filming it. Among other things, critical thinking involves considering the possible outcomes of an action.
