Thought and Knowledge : An introduction to critical thinking(fifth edition)

PREFACE TO THE FIFTH EDITION

lt is hard to believe, but it has been 30 years Since the publicatioJl of the first edition of Tlwught and Knowledge: An lntroduction to Critical Thinking. The world has changed i.n many ways over the last three decades. For the first edition, I wrote all of the text long hand (remember that?) and had it typed by a professional secretary who had a sleek new typewriter with a "tape" that allowed her to white out errors and a return key so she did not have to push the carriage retum at the end of every line. I am guessing that most readers have no idea what anly of this means because they never lived in a world with typewriters or heard of a "carriage return."

But, despite all of the changes in technology in the last 30 years (yes, there was a time when there was no internet), the need to think critically has notchanged. One might argue that it is even more important now that everyone has easy access to more information than they can possibly use and much of that information is biased in ways that can be difficult to detect. lt is to the users of new and emerging technologies that I dedicate this book.

I have many wonderful colleagues, students, and reviewers to thank for their assistance with this editioll. J thank Heather Butler, an extraordinary doctoral student who wiJ] be Dr. Butler by the time you are reading this . She has helped me question, research, and rethink much of what I know about critical thinking. I also thank Amanda Franco, a doctoral student at University of Minho in Portugal for carefully reading an ealy draft of this book alld offering insightful recommelldations. Special thanks to Dr. Heidi Riggio at California State University， Los Angeles, for her careful and creative work on the instructor's materials and student online exercises in this edition of Thought and Knowledge and in previous editions. This edition has a new publisher, Psychology Press, a division of the international publisher Taylor & Francis. The psychology editor Pal Dukes and the editor assigned for this book, Fred Coppersmith, have been supportive throughout the process of bringing this book to print. In addition, I have been fortunate to have suggestions from some of the top luminaries in the field of teaching critical thinking. Some of the reviewers have chosen to remain anonymous, so I thank them anonymously. Sincere thanks to the folJowing reviewers:
