Sun Tzu …

All war is based on deception.

Pretend inferiority and ecnourage his arrogance.

O divine art of subtlety and secrecy! Through you we learn to be invisible, through you inaudible and hence we can hold the enemy’s fate in our hands.

If you know the enemy and know yourself, you need not fear the result of a hundred battles.

All men can see these tactics whereby I conquer, but what none can see is the strategy out of which victory is evolved.

Sun Tzu (544 BC – 496 BC). Author of The Art of War, an immensely influential ancient Chinese book on military strategy. He is also one of the earliest realists in international relations theory.
