New Third Edition -- More Fallacies, More Cartoons

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."

We wrote this book 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.

  • Self-teaching - not intimidating, starts students with skills they can use right away.

  • Each lesson has exercises for students, with an answer key at the back.

  • Covers logical fallacies and propaganda techniques. We divided the most common fallacies and propaganda techniques into thirty-eight lessons. We explain how you can spot fallacies, and we give exercises to stretch your abilities for detecting fallacies.

  • Geared for ages twelve and older - we suggest using The Fallacy Detective before advancing onto more difficult logic programs.

  • Includes The Fallacy Detective Game, giving you and your friends an entertaining way to spot and make up your own examples of fallacies.

  • Christian view of logic. Many critical thinking texts introduce political correctness. This book does not.

  • Can be used before or after The Thinking Toolbox

  • Cartoons to illustrate the logical fallacies discussed, including Peanuts, Dilbert, Calvin and Hobbes, and several original cartoons

This book is for fallacy detectives. We've designed this book to be a handy-dandy text for learning to spot the errors in thinking that you meet everyday on the street, in the newspaper, or on television - or errors you make yourself.
