The book relies upon a traditional approach to argumentation, drawing from established rhetorical theories, and also discusses contemporary theories of argumentation (such as those of Toulmin and Perelman). The text affirms that argumentation is a cooperative and constructive activity, characteristic to humans, and increasingly significant within our diverse contemporary society. This book teaches reasoning skills and covers the basic vocabulary, structure, types, and tests of all major forms of arguments. It also discusses argument ethics and policy case construction, and further includes an extensive discussion of evidence and validity.
