This book implements a new approach to the study of manipulative tactics in selected Congressional debates in the early history of the United States, highlighting the ways in which language can be used to manipulate an audience. The identification and analysis of different informal fallacies is central in the approach adopted by the authors, and they privilege the role of covert intentions as a frequent ingredient of manipulation. They also show how different speakers can use different subtypes of the same fallacy in a debate, and investigate the tension between the policy preferences and goals of politicians, and existing laws. The book has been written without jargon, all concepts and terminology from the field of linguistic pragmatics are clearly defined, and it is accessible to the interested layperson wishing to become familiar with manipulative techniques in political rhetoric.
