《智囊(选录)·明智部·邵雍》
司马温公写信给他说： 忠信的人，在您当权时，虽然往往和您意见有所不合，觉得很可恨，以后您一定会得到他们的帮助；谄媚的人，在当前虽然顺从您，让您觉得很愉快，一旦您失去权势，一定会为了一己私利出卖您。 
温公贻以书曰： 忠信之士，于公当路时虽龃龉可憎，后必得其力；谄谀之人，于今诚有顺适之快，一旦失势，必有卖公以自售者。 
Sima Guang wrote to him: When you are in power, loyal people often disagree with you, which makes you hate them; after you lose your power, those who flatter you will sell you out for their own self-interest.
