《韩非子·扬权》
君主喜欢自夸逞能，正是臣下进行欺骗的凭借；君主喜欢惹事生非，卖弄口才和智力，正是臣下加以利用的依托。
矜而好能，下之所欺：辩惠好生，下因其材。
Monarchs fond of bragging about their capabilities provide their subjects with an opportunity to deceive them, and their fondness for stirring up trouble and showing off their eloquence and intellect can be utilized by their subjects.
