《管子·七法》
不能强化其军队而能必胜敌国的事情，从来没有；但是，能够强化其军队而不明胜敌国之理，仍然不能打胜。
不能彊其兵，而能必胜敌国者，未之有也；能彊其兵，而不明于胜敌国之理，犹之不胜也。
There has never been a case of a country being invincible without its armies being strong; but where there has been the power to strengthen the army, and yet the plan of victory has not been understood, it has yet not been sufficient.
