Our personal and political worlds are rife with arguments and disagreements, some of them petty and vitriolic. The inability to compromise and understand the other side is widespread today. What can we do to change this? In Think Again philosopher Walter Sinnott-Armstrong draws on a long tradition of logic to show why we should stop focusing on winning arguments and instead argue in a more constructive way.Based on a hugely popular online course with more than a million followers around the world, Think Again explains how to analyse, evaluate and make better arguments while also spotting bad reasoning and avoiding certain fallacies. Through lively, practical examples from everyday life, politics and popular culture, Walter Sinnott-Armstrong offers brilliantly straightforward, wise advice that we can all use at work, at home and online.
