Some quotes:
All warfare is based on deception.
One may know how to conquer without being able to do it.
If you know your enemy and know yourself, you need not fear the outcome 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 your enemy nor yourself, you will succumb in every battle.
