Reason and Argument

This text presents a clear and philosophically sound method for identifying, interpreting, and evaluating arguments as they appear in non-technical sources. It focuses on a more functional, real-world goal of argument analysis as a tool for figuring out what is reasonable to believe rather than as an instrument of persuasion. Methods are illustrated by applying them to arguments about different topics as they appear in a variety of contexts - e.g., newspaper editorials and columns, short essays, informal reports of scientific results, etc.(NOTE: Each chapter concludes with a Summary.)
