《智囊(选录)·兵智部·荀罂 伍员》
假如现在就和楚国交战，必然会伤亡惨重，因此应该以不战为上策。所谓聪明的人靠智慧取胜，愚笨的人靠蛮力克敌，这就是先王克敌制胜的道理啊。 
大劳未艾。君子劳心，伍员小人劳力，先王之制也。 
If we fight the state of Chu now, there will definitely be heavy casualties. Therefore, it is better not to fight. The so-called wise people win by wisdom, and the foolish people win by brute force. This is the reason why the former kings defeated their enemies.
