“If one wishes to feign disorder to entice an enemy, he must himself be well-disciplined. Only then can he feign confusion. One who wishes to simulate cowardice and lie in wait for his enemy must be courageous, for only then is he able to simulate fear. One who wishes to appear to be weak in order to make his enemy arrogant must be extremely strong. Only then can he feign weakness. Order or disorder depends on organization; courage or cowardice on circumstances; strength or weakness on dispositions. When troops gain a favorable situation the coward is brave; if it be lost, the brave become cowards. In the art of war there are no fixed rules. These can only be worked out according to circumstances. Thus, those skilled at making the enemy move do so by creating a situation to which he must conform; they entice him with something he is certain to take, and with lures of ostensible profit they await him in strength. Therefore a skilled commander seeks victory form the situation and does not demand it of his subordinates.”
