Logically Fallacious

This book is a crash course, meant to catapult you into a world where you start to see things how they really are, not how you think they are.  The focus of this book is on logical fallacies, which loosely defined, are simply errors in reasoning.  With the reading of each page, you can make significant improvements in the way you reason and make decisions.

Expose an irrational belief, keep a person rational for a day.  Expose irrational thinking, keep a person rational for a lifetime.

- Bo Bennett

Academic Edition!

The academic edition was released on November 22, 2013.  As with the first edition, it contains over 300 logical fallacies with over 500 detailed examples.  The academic edition was edited using APA format and the examples were checked to be more suitable for academic environments that comprise people of all and no religious beliefs.
