《三国志·蜀书·杜周杜许孟来尹李谯郤》
《易经》说: 亢字的意思是只知道进取而不知道退让，知道生存而不知道死亡，知道得失存亡而不失其正者，难道只有圣人吗？ 
易曰： 亢之为言，知得而不知丧，知存而不知亡；知得失存亡而不失其正者，其惟圣人乎！ 
The Book of Changes says: The character "亢" means only knowing how to advance but not how to retreat, knowing how to live but not how to die, knowing about gains and losses and life and death but not losing one's righteousness. Is it only the saints who are like this?
