This book is aimed at newcomers to the field of logical reasoning, particularly those who, to borrow a phrase from Pascal, are so made that they understand best through visuals. I have selected a small set of common errors in reasoning and visualized them using memorable illustrations that are supplemented with lots of examples. The hope is that the reader will learn from these pages some of the most common pitfalls in arguments and be able to identify and avoid them in practice.

"I love this illustrated book of bad arguments. A flawless compendium of flaws."

-Prof. Alice Roberts, Anatomist, Presenter of the BBC's 'The Incredible Human Journey'


"A wonderfully digestible summary of the pitfalls and techniques of argumentation. I can't think of a better way to be taught or reintroduced to these fundamental notions of logical discourse. A delightful little book."

-Aaron Koblin, Creative Director of the Data Arts team at Google
