The laws cull their principles from many great schemers--and scheming instructors--throughout history, from Sun-Tzu to Talleyrand, from Casanova to con man Yellow Kid Weil. They are straightforward in their amoral simplicity: "Get others to do the work for you, but always take the credit," or "Discover each man's thumbscrew." Each chapter provides examples of the consequences of observance or transgression of the law, along with "keys to power," potential "reversals" (where the converse of the law might also be useful), and a single paragraph cleverly laid out to suggest an image (such as the aforementioned thumbscrew); the margins are filled with illustrative quotations. Practitioners of one-upmanship have been given a new, comprehensive training manual, as up-to-date as it is timeless.
