This textbook is intended for use in a course on scientific thought. It includes a mixture of classic readings from the great figures in science and in the philosophy of science, as well as practical essays on scientific methodology, ethics and pseudoscience. Students will be introduced to the scientific world view: its sphere and limitations. The book develops the methodology, epistemology, history and philosophy of science. It will give the student tools to reflect on the ethical implications of scientific discovery. In addition, the student will be trained in skepticism and critical thinking in order to distinguish pseudoscience from real science. In addition the distinction between scientific and religious thought will be considered, as well as a discussion of the questions of interest to both. John Oakes received his bachelor of science in chemistry from the University of Connecticut in 1977 and his PhD in chemical physics from the University of Colorado, Boulder. Dr. Oakes has been a professor of chemistry and physics at Gonzaga University, Marian College (Wisconsin) and Grossmont College. He has taught classes on the history and philosophy of science for over twenty years and directed honors programs at both Marian College and Grossmont College. He has published six books and given invited lectures on science and religion at dozens of universities and in more than fifty countries. Richard Alpert has a B.S. degree in chemistry from Rutgers University and a Ph.D. from the Polytechnic Institute of Brooklyn. Working as a material scientist in industry for thirty-five years and a teacher for about ten years, his research approach was to understand the physics of the problem first before working on the chemistry. He currently has about ten patents and twenty-five publications.

The Thinker’s Guide to Scientific Thinking focuses on developing the intellectual skills inherent in the well-cultivated practice of every area of scientific research and study. It helps students and practicing scientists come to reason within the logic of science and to see the field as a cohesive whole. From astronomers to zoologists and physicists to chemists, skilled scientists use careful analysis to question data, test theories, draw logical conclusions, and propose feasible solutions. Students in science courses, and scientists themselves will find their analytical abilities enhanced by the engaging framework of inquiry set forth by Richard Paul and Linda Elder in this guide. As part of the Thinker’s Guide Library, this book advances the mission of the Foundation for Critical Thinking to promote fairminded critical societies through cultivating essential intellectual abilities and virtues across every field of study across world.

I have tried to make this book an argument, not a catalogue of dogmas. Its ideal reader will find himself constantly asking questions, for which he will insist on finding his own answers. To avoid wasting his time, I have made the fullest use of authentic illustrations from newspapers, books, and other contemporary sources. One of the wisest things ever said about our subject is that “Logic, like whiskey, loses its beneficial effect when taken in too large doses.” While bearing this constantly in mind, I have also aimed at a high level of accuracy and the inclusion of nothing that would have to be unlearnt at a more advanced level of study. This book could never have been written without the help of the students to whom I have lectured on logic and scientific method. My chief obligations are to them. Logic ought to be easy, interesting, and enjoyable. This book will have been successful if it helps some readers to find it so.—Prof. Max Black
