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.
If we know that our own men are in a condition to attack, but are unaware that the enemy is not open to attack, we have gone only halfway towards victory.
The skilful employer of men will employ the wise man, the brave man, the covetous man, and the stupid man.
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.
All men can see these tactics whereby I conquer, but what none can see is the strategy out of which victory is evolved.
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.
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.
