墨子有段名言：“丝染于苍则苍,染于黄则黄,所入者变,其色亦变……故染不可不慎也。”以此为喻,进而指出不仅丝有染,“国亦有染”、“士亦有染”,形象地说明了环境对人的影响。此言对人们培植思想、拒腐防变颇有启示。 Mozi has a famous saying: “Smectite in the dark green Cang, dyed yellow Huang, who change, the color also change ... so the accidental also can not be stained.” This as a metaphor, and then pointed out that not only silky, “The country also has the dye”, “the doctor also has the dye”, vividly explained the environment to the human influence. This remark inspires people to cultivate their ideas and prevent corruption.
