The Power of Critical Thinking 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 organization of the book is very clear, and chapters are appropriately divided between important topics. The ordering of the chapters is appropriate and thoughtful. The range of topics is breathtaking. The addition of a full chapter on digital media literacy (Chapter 5) is my favorite change from the sixth to the seventh editions."--Crystal Rose "Well-organized, clear, addresses all the major topics, good exercises. I especially like the attention paid to inference to best explanation."--Jonathan Ruben Cohen "I really appreciate the sections on recognizing one's own bias. The Media, Science, and Morality are new to textbooks, other than the Paul Elder book. I find this incredibly useful and relevant for our times. The sections on logic are very accessible for students."--Quincy Leigh Foley "This book is about as clear as a logic textbook can be (and much better than others I have used)."--James McRae
