《资治通鉴·周纪·周纪一》
君臣都自以为贤能，下属又同声称贤，称赞贤能则和顺而有福，指出错误则忤逆而有祸，这样，怎么会有好的结果！
君臣既自贤矣，而群下同声贤之，贤之则顺而有福，矫之则逆而有祸，如此则善安从生！
When both the prince and his ministers think themselves wise, and when the subordinates all speak with the same voice, then to speak of being wise and harmonious is to invite blessings, and to speak of error is to invite punishment. How can there be good results?
