Book excerpt: The Argument Handbook is a classroom text for first-year composition that is designed to help students understand complex rhetorical situations and navigate the process of transforming private thoughts into persuasive, public writing. The book is organized around three key lenses of argumentation that help students focus on the practical challenges of persuasive writing: invention, audience, and authority. Its modular organization makes it easier for students to find what they need and easier for instructors to assign the content that fits their course.
