This is a brief introduction to argumentation and debate. It is based on the principle that arguments are not only advocacy of certain position, but also a part of dialogue in finding the best answers to the most difficult questions. The book explores methods in developing arguments on the questions of fact, value, and policy. It emphasizes the point that argumentative skill can be practiced best when working on matters related to policymaking: in finding practical solutions to practical problems. Also, the book covers types of reasoning, logical fallacies, the evidence, and teaches style and delivery. Each chapter ends with a list of key terms, exercises, and study questions making the book a valuable text for college courses in argumentation and critical thinking.
