Youll love this book or youll hate it. So, youre either with us or against us. And if youre 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 shes 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 Argumentsdemonstrates how misguided arguments come to be, and what we can do to detect them in the rhetoric of others and avoid using them ourselves.
Fallaciesor conclusions that dont follow from their premiseare 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 ofsunk costs, is ought, affirming the consequent, moving the goal post, begging the question,or the ever-popularslippery 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 volumeJust the Arguments(2011),Bad Argumentsis an essential tool for undergraduate students and general readers looking to hone their critical thinking and rhetorical skills.
