The chapters build on one another. The organization is sound and the author does a superior job of presenting the structure of arguments. " David M. Adams, California State Polytechnic University "These examples work quite well. Their diversity, literacy, ethnic sensitivity, and relevancy should attract readers." Stanley Baronett. Jr., University of Nevada Las Vegas Far too many authors of contemporary texts in informal logic – keeping an eye on the sorts of arguments found in books on formal logic – forget, or underplay, how much of our daily reasoning is concerned not with arguments leading to truth-valued conclusions but with making choices, assessing reasons, seeking advice, etc.
