《韩非子·人主》
这三个人，做臣子不是不忠，建议不是不恰当，但是最终不免于死亡的祸患，原因就在君主不明察贤士和智者的主张，而受蠢才和恶人的蒙蔽。
此三子者，为人臣非不忠，而说非不当也，然不免于死亡之患者，主不察贤智之言，而蔽于愚不肖之患也。
These three people were not disloyal as ministers, and their suggestions were not inappropriate, but in the end they could not escape the danger of death. The reason was that the monarch did not understand the propositions of the virtuous scholars and wise men, and was deceived by fools and wicked people.
