Have you read (or stumbled into) one too many irrational online debates? Ali Almossawi certainly had, so he wrote An Illustrated Book of Bad Arguments! This handy guide is here to bring the internet age a much needed dose of old-school logic (really old-school, a la Aristotle).

Here are cogent explanations of the straw man fallacy, the slippery slope argument, the ad hominem attack, and other common attempts at reasoning that fall short — plus a beautifully drawn menagerie of animals who (adorably) commit every logical faux pas. Rabbit thinks a strange light in the sky must be a UFO because no one can prove otherwise (the appeal to ignorance). And Lion doesn’t believe that gas emissions harm the planet because, if that were true, he wouldn’t like the result (the argument from consequences).

Once you learn to recognise these abuses of reason, they start to crop up everywhere from parliamentary debate to YouTube comments — which makes this geek-chic book a must for anyone in the habit of holding opinions. It’s the antidote to fuzzy thinking, with furry animals!

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

'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.'

'Seriously, An Illustrated Book of Bad Arguments should be on every school curriculum. Twitter will be a more civil place.'

'Bad arguments, great illustrations … gorgeous.'

'[A] wonderful primer on the logical fallacies that have been screwing up our thinking … since shortly after the invention of dirt.'

'A great primer for anyone looking to understand logical fallacies … Pass it along to the arguers — good and bad — in your life.'
