《荀子·仲尼》
回答说：因为五霸不把政治教化作为治理国家的根本，没有尽力推崇礼仪，教化人民，无法让人心悦诚服；他们只是些注重方法策略，合理安排作息，使人民积蓄财物，加强战备因而能打败他们的敌人，他们依靠计谋取胜，以谦让来掩饰争夺，以仁爱之名来追求实利，他们是小人中的佼佼者，这样的人怎么会被孔子门人称道呢？ 
曰：然。彼非本政教也，非致隆高也，非綦文理也，非服人之心也。乡方略，审劳佚，畜积修斗而能颠倒其敌者也。
The answer is: Because the Five Tyrants did not take political education as the foundation of governing the country, they did not do their best to promote etiquette and educate the people, and they could not make people convinced; They just focus on methods and strategies, arrange work and rest reasonably, make the people accumulate wealth, strengthen their war preparations and defeat their enemies. They rely on strategy to win, use modesty to cover up contention, and pursue profit in the name of benevolence. Among the villains, how could such people be praised by Confucius' disciples?
