《宋史·列传·卷二百零二》
有人会说： 所谓心机，只有创业之君才借助于它，作为守成之世，君子有什么必要把事情搞得那么神秘，有什么必要信用心腹之臣呢？ 
或曰： 机者，创业之君所假以济耳，守成之世，其奚事机而安用夫腹心之臣？ 呜呼！
Some people would say: So-called discretion is only used by emperors who start a business. As for the world of preserving accomplishments, what necessity is there for gentlemen to make things so mysterious? What necessity is there to rely on a confidant?
