Review

I love your book! I never knew how much fun logic was until I read your book. P.S. I am 12 years old. - Paul Muenzler --Student

I'm always delighted when two sides that seem mutually opposed come together in harmonious agreement. I'm even more delighted when I've taken one of those sides. In this case, I write of the efforts of Nathaniel and Hans Bluedorn, brothers from Iowa who advocate homeschooling and create educational materials from a Christian worldview. The fruit of the latest Bluedorn effort is a short text, The Fallacy Detective, designed to be a primer in logic for older children, specifically homeschooled Christian children, though the book is intended for anyone who wants to explore the subject. . . .

. . . I find it wonderful that the Bluedorns, among others, are actively reinvigorating the religious world with a healthy dose of independent thought . . . - Andrew C. Thomas (The Tech) --The Tech, Massachusetts Institute of Technology

My family and I are really enjoying your book. Even my youngest son, who is eight, enjoys attempting to answer the questions. Your book was a great introduction to another program that I had purchsed. Going directly into that program probably would have bored my children to tears but now they are interested in the concepts of logic. My children became instantly attracted to the program because of the the comic segments but later couldn't put it down. - LaVera, MD --Parent

5.0 out of 5 stars Great For Kids or Adults, June 6, 2005

By	Tim Challies (Oakville, Ontario) - See all my reviews (TOP 500 REVIEWER)    (REAL NAME)

This review is from: The Fallacy Detective: Thirty-six lessons on how to recognize bad reasoning (Paperback)

The Fallacy Detective, written by Hans and Nathaniel Bluedorn, is a book designed for teens or adults that teaches how to spot common errors in reasoning. The goals for this book are clearly laid out in the introduction. When the reader has completed this book he should be able to put a high value on good reasoning, know how to spot many forms of bad reasoning and know how to avoid using many fallacies in his own reasoning.

The authors provide a vision of Christian logic in which they appeal to the need for Christians to strive for a higher standard of reasoning, in order to attain greater ability in discernment. Logic is an important foundation for the science of discernment. Thus they seek to define good reasoning in a biblical way. "Logic is the science of thinking the way God thinks - the way Jesus taught us to think" (page 14).

The book contains thirty-six lessons which progress from the most common and basic fallacies, to statistical fallacies and even propaganda. All those terms I have not heard since my university Critical Thinking courses are present as well as some that are commonly used and misused: red herring, ad hominem, tu quoque, appeal to the people, part-to-whole, whole-to-part and so on. Each lesson is followed by several questions which allow the reader to apply what he has just learned. I was glad to see that the questions are cumulative, meaning that what has been taught in previous lessons is continually reviewed in the application questions for subsequent chapters.

The authors write in a style that will appeal to teens and young people. The text is interspersed with comics (such as Calvin & Hobbes, Peanunts and Dilbert) and anecdotes. It is also a funny book, as there are many places where the authors turn to humor to make the book enjoyable. A typical lesson may begin similar to this one, which discusses weak analogies: "Let's say...you are a budding scientist wanting to write your graduate thesis on the long term effects of Pop-Tarts on humans. The only problem is, you can't find enough people who are willing to eat thirty-four Pop-Tarts a day for one year" (page 131).

Can learning logic be fun? With The Fallacy Detective it appears that it can be. I thoroughly enjoyed this book and would recommend it to anyone who wants to improve his reasoning skills. While its primary usefulness will be for teenagers, adults will also enjoy it and benefit from the lessons. If you homeschool your children, this may be a useful title.

5.0 out of 5 stars Hilarious and educational, August 11, 2005

A Kid's Review

A wonderful little logic book, that can be enjoyed on several levels. First of all it is a great homeschooling resource. Second, it's a useful way to get research if you're stuck on a logic test. Thirdly, it is peppered throughout with great cartoons from the classics "Calvin and Hobbes" and "Peanuts" as well as the less classic "Dilbert." Lastly, it's just plain hilarious! You'll laugh your head off with anecdotes about putting a smoke detector in the fireplace. Absolutely, don't miss.

5.0 out of 5 stars Cute with a critical thinking point, February 21, 2005

By	E. Johnson (El Cajon, CA United States) - See all my reviews (TOP 500 REVIEWER)    (REAL NAME)

This review is from: The Fallacy Detective: Thirty-six lessons on how to recognize bad reasoning (Paperback)

The Fallacy Detective cannot be a good book because it was written by homeschoolers.

Ooops, there I go again, using a genetic fallacy. It's what you'll learn from a couple of home-school educated detectives who aim their book at those 13 and older. There are a number of cartoons--from Peanuts and Dilbert to a cartoon written by the authors' sister--that help keep interest in the simple, straightforward book as it deals with several dozen common fallacies. The exercises will help keep the student on the straight and narrow, making sure the ideas are solidified in the mind. I do recommend this book for kids as well as adults who would like to sharpen their critical thinking skills.
