Simulated disorder postulates perfect discipline, simulated fear postulates courage; simulated weakness postulates strength.
Hiding order beneath the cloak of disorder is simply a question of subdivision; concealing courage under a show of timidity presupposes a fund of latent energy; masking strength with weakness is to be effected by tactical dispositions.
Thus one who is skillful at keeping the enemy on the move maintains deceitful appearances, according to which the enemy will act. He sacrifices something, that the enemy may snatch at it.
By holding out baits, he keeps him on the march; then with a body of picked men he lies in wait for him.
– The Art of War (5th century BC) – Sun Tzu
