A timely and accessible guide to 100 of the most infamous logical fallacies in Western philosophy, helping readers avoid and detect false assumptions and faulty reasoning You’ll love this book or you’ll hate it. So, you’re either with us or against us. And if you’re against us then you hate books. No true intellectual would hate this book. Ever decide to avoid a restaurant because of one bad meal? Choose a product because a celebrity endorsed it? Or ignore what a politician says because she’s not a member of your party? For as long as people have been discussing, conversing, persuading, advocating, proselytizing, pontificating, or otherwise stating their case, their arguments have been vulnerable to false assumptions and faulty reasoning. Drawing upon a long history of logical falsehoods and philosophical flubs, Bad Arguments demonstrates how misguided arguments come to be, and what we can do to detect them in the rhetoric of others and avoid using them ourselves. Fallacies—or conclusions that don’t follow from their premise—are at the root of most bad arguments, but it can be easy to stumble into a fallacy without realizing it. In this clear and concise guide to good arguments gone bad, Robert Arp, Steven Barbone, and Michael Bruce take readers through 100 of the most infamous fallacies in Western philosophy, identifying the most common missteps, pitfalls, and dead-ends of arguments gone awry. Whether an instance of sunk costs, is ought, affirming the consequent, moving the goal post, begging the question, or the ever-popular slippery slope, each fallacy engages with examples drawn from contemporary politics, economics, media, and popular culture. Further diagrams and tables supplement entries and contextualize common errors in logical reasoning. At a time in our world when it is crucial to be able to identify and challenge rhetorical half-truths, this bookhelps readers to better understand flawed argumentation and develop logical literacy. Unrivaled in its breadth of coverage and a worthy companion to its sister volume Just the Arguments (2011), Bad Arguments is an essential tool for undergraduate students and general readers looking to hone their critical thinking and rhetorical skills.

“This short book makes you smarter than 99% of the population. . . . The concepts within it will increase your company’s ‘organizational intelligence.’. . . It’s more than just a must-read, it’s a ‘have-to-read-or-you’re-fired’ book.”—Geoffrey James, INC.com From the author of An Illustrated Book of Loaded Language, here’s the antidote to fuzzy thinking, with furry animals! 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 actually 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 recognize these abuses of reason, they start to crop up everywhere from congressional debate to YouTube comments—which makes this geek-chic book a must for anyone in the habit of holding opinions.

Whether the law should permit voluntary euthanasia or physician-assisted suicide is one of the most vital questions facing all modern societies. Internationally, the main obstacle to legalisation has proved to be the objection that, even if they were morally acceptable in certain 'hard cases', voluntary euthanasia and physician-assisted suicide could not be effectively controlled; society would slide down a 'slippery slope' to the killing of patients who did not make a free and informed request, or for whom palliative care would have offered an alternative. How cogent is this objection? This book provides the general reader (who need have no expertise in philosophy, law or medicine) with a lucid introduction to this central question in the debate, not least by reviewing the Dutch euthanasia experience. It will interest all in any country whether currently for or against legalisation, who wish to ensure that their opinions are better informed.

This textbook examines the ways in which arguments may be used and abused in medicine and health. The central claim is that a group of arguments known as the informal fallacies – including slippery slope arguments, fear appeal, and the argument from ignorance – undertake considerable work in medical and health contexts, and that they can in fact be rationally warranted ways of understanding complex topics, contrary to the views of many earlier philosophers and logicians. Modern medicine and healthcare require lay people to engage with increasingly complex decisions in areas such as immunization, lifestyle and dietary choices, and health screening. Many of the so-called fallacies of reasoning can also be viewed as cognitive heuristics or short-cuts which help individuals make decisions in these contexts. Using features such as learning objectives, case studies and end-of-unit questions, this textbook examines topical issues and debates in all areas of medicine and health, including antibiotic use and resistance, genetic engineering, euthanasia, addiction to prescription opioids, and the legalization of cannabis. It will be useful to students of critical thinking, reasoning, logic, argumentation, rhetoric, communication, health humanities, philosophy and linguistics.

In the second edition of this witty and infectious book, Madsen Pirie builds upon his guide to using - and indeed abusing - logic in order to win arguments. By including new chapters on how to win arguments in writing, in the pub, with a friend, on Facebook and in 140 characters (on Twitter), Pirie provides the complete guide to triumphing in altercations ranging from the everyday to the downright serious. He identifies with devastating examples all the most common fallacies popularly used in argument. We all like to think of ourselves as clear-headed and logical - but all readers will find in this book fallacies of which they themselves are guilty. The author shows you how to simultaneously strengthen your own thinking and identify the weaknesses in other people arguments. And, more mischievously, Pirie also shows how to be deliberately illogical - and get away with it. This book will make you maddeningly smart: your family, friends and opponents will all wish that you had never read it. Publisher's warning: In the wrong hands this book is dangerous. We recommend that you arm yourself with it whilst keeping out of the hands of others. Only buy this book as a gift if you are sure that you can trust the recipient.

This book provides theoretical tools for evaluating the soundness of arguments in the context of legal argumentation. It deals with a number of general argument types and their particular use in legal argumentation. It provides detailed analyses of argument from authority, argument ad hominem, argument from ignorance, slippery slope argument and other general argument types. Each of these argument types can be used to construct arguments that are sound as well as arguments that are unsound. To evaluate an argument correctly one must be able to distinguish the sound instances of a certain argument type from its unsound instances. This book promotes the development of theoretical tools for this task.

Uses Jesus' words and actions found in the New Testament to systematically evaluate his rhetorical stylings, drawing real lessons from his teachings that today's readers can employ. Jesus of Nazareth never wrote a book, held political office, or wielded a sword. He never gained sway with the mighty or influential. He never took up arms against the governing powers in Rome. He was a lower-class worker who died an excruciating death at the age of thirty-three. Yet, in spite of all odds-obscurity, powerlessness, and execution-his words revolutionized human history. How to Argue Like Jesus examines the life and words of Jesus and describes the various ways in which he sought-through the spoken word, his life, and his disciples-to reach others with his message. The authors then pull some very simple rhetorical lessons from Jesus' life that readers can use today. Both Christian and non-Christian leaders in just about any field can improve their ability to communicate effectively by studying the words and methods of history's greatest communicator.

Douglas Walton rejects the view that the slippery slope argument is a fallacy, contending that such arguments can be used correctly in some cases as a reasonable type of argument to shift a burden of proof in a critical discussion.
