Quotes

Chapter Quote
Chapter 1: Laying Plans "All warfare is based on deception. Hence, when we are able to attack, we must seem unable; when using our forces, we must appear inactive; when we are near, we must make the enemy believe we are far away; when far away, we must make him believe we are near."
Chapter 3: Attack by Stratagem "If you know the enemy and know yourself, you need not fear the result of a hundred battles. If you know yourself but not the enemy, for every victory gained you will also suffer a defeat. If you know neither the enemy nor yourself, you will succumb in every battle."
Chapter 6: Weak Points and Strong "Appear at points which the enemy must hasten to defend; march swiftly to places where you are not expected."
Chapter 7: Maneuvering "Let your plans be dark and impenetrable as night, and when you move, fall like a thunderbolt."
Chapter 8: Variation in Tactics "In the midst of chaos, there is also opportunity."
Chapter 11: The Nine Situations "He who knows when he can fight and when he cannot, will be victorious."
Chapter 12: Attack by Fire "Move not unless you see an advantage; use not your troops unless there is something to be gained; fight not unless the position is critical."
Chapter 13: The Use of Spies "Be subtle! Be subtle! And use your spies for every kind of business."
