The Thinking Toolbox: Thirty-Five Lessons That Will Build Your Reasoning Skills, by Nathaniel Bluedorn and Hans Bluedorn, illustrated by Richard LaPierre, ISBN 0974531510, 234 pp. Christian Logic, 2005.
Nathaniel and Hans Bluedorn are brothers who live in Indiana (more about them at www.christianlogic.com) and The Thinking Toolbox is a follow-up to their first book, The Fallacy Detective. These books are primarily intended for use as homeschooling textbooks, and the Bluedorns’ interest in this area stems largely from their education at home growing up.
In an interview, Nathaniel gets at the intention behind the book: to make logic accessible and enjoyable for students. “Logic books are notorious for being very difficult, very austere,” he says. Instead, logic should be “a very enjoyable thing that everybody can do.” Hans affirms that the first step is to get kids to “think at all, and then the next step is to get them to think correctly.”
The book is a course of 35 lessons, with illustrations, applications, and exercises forming distinct little units. Colorful illustrations abound in the book, courtesy of Richard LaPierre. The book starts with the most basic building blocks of critical thinking, inculcating rules like “Just because somebody tells you something, that doesn’t mean it is true,” and moving on to examine things like the different kinds of discourse, and recognizing the difference between facts, opinions, and inferences.
