This extensively updated second edition provides a comprehensive introduction to argumentation skills for undergraduates. Clearly written, with minimal technical jargon, the book features many contemporary real-world examples. Through a unique conceptual framework, students will learn how to assemble a coherent logical argument, assess sources, and organize and present written and verbal arguments. The authors use the Toulmin model throughout to present issues and clarify concepts and have expanded the model to show how it can be used to examine real-world arguments. This new edition provides a deeper focus on value claims and credibility. It also shows students how to assess fake news, misinformation, and post-truth and incorporates more social scientific theories of persuasion such as the Elaboration Likelihood Model. Argumentation: Keeping Faith with Reason is an ideal textbook for undergraduate courses in argumentation, persuasion, critical thinking, and informal logic. An Instructorβs Manual including advice on how to teach each section, sample quizzes, and additional examples is available at https://routledge.com/9781032541228.
