Fallacy Detective Workbook Edition
by Harvey Bluedorn
The Fallacy Detective has been the best selling text for teaching logical fallacies and introduction to logic for over 15 years.
What is a fallacy? A fallacy is an error in logic – a place where someone has made a mistake in his thinking.
“A cloud is 90% water. A watermelon is 90% water. Therefore, since a plane can fly through a cloud, a plane can fly through a watermelon.”
This is an easy book for learning to spot common errors in reasoning.
“Cartoon and comic illustrations, humorous examples, and a very reader-friendly writing style make this the sort of course students will enjoy.” -Cathy Duffy, homeschool curriculum reviewer

Thinking Toolbox
by Harvey Bluedorn
This book is like a toolbox, full of different kinds of tools you can use for different thinking tasks. Just as you use the wrench in a regular tool box to fix the sink, so you can use the tools we give you in this book to solve thinking problems.
We wrote this book for children and adults who want to learn logic and critical thinking skills. The Thinking Toolbox follows the same style as The Fallacy Detective with lessons and exercises and an answer key in the back. Parents and teachers, as well as anybody who wants to learn logic, will find The Thinking Toolbox easy to use and practical.
