The book you have just opened is probably unlike anything you have ever read so far. It offers you a path to direct contact with "e;The Art of War"e;, the masterpiece of Sun Tzu, a classical theorist of warfare in Ancient China. This book examines an ancient Chinese work on strategy and warfare: Sun Tzu, "e;The Art of War"e;, from the perspectives of logic, mathematics, and computer science. Sun Tzu's book has been studied and translated many times before, with viewpoints from historians, military- and business strategists, philosophers, and in the context of modern computer strategy games. This book takes a new approach to study this 2500-year-old text. It uses modern mind mapping techniques to show a new dimension that uncovers meaning and structure not easily seen before. Mind maps are semantic diagrams of related concepts: they are used in this book in a restricted form, defined as Text Tree Mind Maps. A chapter coveringthe theoretical side of diagramming ancient text, explains the making of the mind maps used in this book and why showing old text in this way is so useful.
