“Walton offers some very perceptive criticisms and points on the subject of emotional appeals. His critique of the standard textbook treatment of the subject is a valuable counter to the excesses of the conventional wisdom that this treatment perpetuates, and his observations on the necessity of considering context when assessing the cogency of arguments based on emotional appeals throw important light on the subtleties of such assessments. In these and other ways his book corrects and enlarges our understanding of informal fallacies.”—John Deigh Informal Logic
