The Fallacy Detective--
Thirty-Six Lessons on How to Recognize Bad Reasoning
by Nathaniel Bluedorn and Hans Bluedorn
What is a fallacy? A fallacy is an error in logic - a place where someone has made a mistake in his thinking.
These are fallacies:
"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 new book, The Fallacy Detective, must do a good job teaching logic. It has been on the bestseller list for months."

This book was written to meet the needs of Christian parents who want a do-able text for introducing logic and critical thinking to their children.

• Fun to use - not dry like a math textbook.

Learning Logic at Home Booklet
Logic is a mystery subject. No one really knows how to teach it. This booklet tries to remove some of the mystery about what logic is, how ordinary Christians can learn logic, and what materials to use.

In Learning Logic at Home I have explained a suggested course of study for children and adults. In this course of study, logic is treated much the same way as math is commonly taught. I describe what is truly involved in learning logic. Also I have tried to give practical suggestions regarding how to use the materials. - Nathaniel
