It includes chapters on the nature and structure of argument, the role of relevance, truth and generalizations, and the subtleties of verbal and visual language.

With an interactive companion website and a comprehensive instructor's manual, Critical Thinking is the ideal textbook for a course in the fundamentals of sound reasoning.
