A practical introduction to critical thinking across various disciplines

Knowing how to think critically about what to believe and what to do is essential for success in both academic and professional environments. A Practical Guide to Critical Thinking introduces readers to the concepts, methods, and standards for thinking critically about reasons and arguments in virtually any area of practice. While most literature on critical thinking focuses on its formal applications within philosophy, this book offers a broad conception of critical thinking and explores its practical relevance to conducting research across a wide variety of disciplines, including business, education, and the biological sciences.

While the book pursues an interdisciplinary approach to critical thinking, providing examples and illustrations from diverse subjects and fields of research, it also provides strategies to help readers identify the methods and standards that are characteristic of critical thinking in their chosen branches of learning, in their workplace, and in their own lives. The concept of an argument is extended beyond its philosophical roots to include experimentation, testing, measurement, policy development and assessment, and aesthetic appreciation as activities that require critical thinking. The logical, core concepts of critical thinking are presented in a rigorous yet informal way, with creative and practical strategies for defining, analyzing, and evaluating reasons and arguments wherever they are found. Each chapter ends with a "Mistakes to Avoid" section as well as a variety of exercises designed to help readers integrate and extend the chapter's lessons.

A Practical Guide to Critical Thinking is an excellent book for courses on critical thinking and logic at the upper-undergraduate and graduate levels. It is also an appropriate reference for anyone with a general interest in critical thinking skills.

“For an absolute beginner, in either logic or philosophy, but also in other disciplines (where we do not indeed need \reasonable, reflective thinking"?), this book may constitute a more substantial basis which may also raise an interest for a more conventional logic course.”  (Zentralblatt  MATH, 1 August 2013)

  • The book covers the fundamental logical concepts of validity and cogency without introducing formal systems. Logical skills are presented within the context of their applications.
  • Chapter exercises are plentiful and appropriately graded for level of difficulty.
  • An Instructor’s Manual is available for further teacher insights and selected solutions.
  • The author’s background lends support to the notion that the book will not be completely void of some mathematical reasoning; though, as noted throughout the text, the author clearly and simply distinguishes between formal and informal logic.
