The only thing necessary for the triumph of evil is for good men to do nothing.
翻译：天空高高在上而大地在人们脚下，乾坤所代表的天地的位置就确定了；把在人们脚下的和高高在上的罗列出来，高下与卑贱事物的地位就排定了；运动与静止有规律，阳刚和阴柔就明确分开了。
处于逆境中，就好比周身都扎着针、敷着药；冥冥中却能磨炼人的意志、培养高尚的品行。处于顺境中，就好比被各种各样的兵器包围；冥冥中掏空了身体，消磨了向上进取的意志。
The story is told by the dead, and the dead have no need for lies.
