The accounts of Ninjutsu that make up this book provide the modern-day practitioners-and readers in general-with a wide variety of perspectives on the art, posited by a broad array of individuals. The chapters are written by authors who are not Ninjutsu instructors. As such, they are not followers of any organization or system of ninjutsu; they owe no allegiance to any particular philosophy or set of beliefs; and, to put it crudely, they "do not have a dog or horse in the race." The objective in compiling these writings is to provide students with information that is independent of the perspectives put forth by the popular Ninjutsu factions, for such views are often skewed and self-serving, and their repeated rhetoric soon becomes tedious and, worse, uninformative. The book encourages those interested in the Arts of the Ninja to read the work of non-partisan authors (like those included here); authors whose underlying motivations are to inform and educate-not market, sell, and recruit.
