This is the ultimate 'how-to' book for anyone who wants to use reasons and evidence in support of conclusions, to be clear instead of confusing, persuasive instead of dogmatic, and better at evaluating the arguments of others. No one outgrows its forty-five timeless rules, all explained and illustrated with vivid examples. The fourth edition, even more elegantly organized and concise than before, adds new material on oral presentations and Web sources that everyone needs. --Debra Nails, Michigan State University
