Danh ngôn của Sun Tzu (Sứ mệnh: 4)

Quickness is the essence of the war.
There is no instance of a nation benefitting from prolonged warfare.
Thus it is that in war the victorious strategist only seeks battle after the victory has been won, whereas he who is destined to defeat first fights and afterwards looks for victory.
Now the reason the enlightened prince and the wise general conquer the enemy whenever they move and their achievements surpass those of ordinary men is foreknowledge.
Thus, what is of supreme importance in war is to attack the enemy's strategy.
Secret operations are essential in war; upon them the army relies to make its every move.
If our soldiers are not overburdened with money, it is not because they have a distaste for riches; if their lives are not unduly long, it is not because they are disinclined to longevity.
All men can see these tactics whereby I conquer, but what none can see is the strategy out of which victory is evolved.
If you know the enemy and know yourself you need not fear the results of a hundred battles.
The general who advances without coveting fame and retreats without fearing disgrace, whose only thought is to protect his country and do good service for his sovereign, is the jewel of the kingdom.
The supreme art of war is to subdue the enemy without fighting.
Know thy self, know thy enemy. A thousand battles, a thousand victories.
There has never been a protracted war from which a country has benefited.
Invincibility lies in the defence; the possibility of victory in the attack.
He who is prudent and lies in wait for an enemy who is not, will be victorious.
Victorious warriors win first and then go to war, while defeated warriors go to war first and then seek to win.
Prohibit the taking of omens, and do away with superstitious doubts. Then, until death itself comes, no calamity need be feared.
In the practical art of war, the best thing of all is to take the enemy's country whole and intact; to shatter and destroy it is not so good.
It is only the enlightened ruler and the wise general who will use the highest intelligence of the army for the purposes of spying, and thereby they achieve great results.
Regard your soldiers as your children, and they will follow you into the deepest valleys; look on them as your own beloved sons, and they will stand by you even unto death.
Victory usually goes to the army who has better trained officers and men.
Balk the enemy's power; force him to reveal himself.
A good commander is benevolent and unconcerned with fame.
The art of war is of vital importance to the state. It is a matter of life and death, a road either to safety or to ruin. Hence it is a subject of inquiry which can on no account be neglected.
The art of war teaches us to rely not on the likelihood of the enemy's not coming, but on our own readiness to receive him; not on the chance of his not attacking, but rather on the fact that we have made our position unassailable.
