Good Reasoning Matters! Fourth Edition takes an innovative approach to critical thinking. Rather than placing emphasis on bad arguments, the authors instead identify the essential structure of good arguments in a variety of contexts while providing guidelines to help students build their own.

Through emphasis on good reasoning, sections of the book examine the most common problems associated with bad reasoning including slanting, bias, propaganda, vagueness, ambiguity, and a common failure to consider opposing points of view.
