《商君书·赏刑》
从此天下人都知道周公将刑罚用在了朝廷内，国境内的秩序得到治理。因此说： 公正严明的刑罚用到一定程度，等于没有刑罚。 
故天下知用刀锯于周庭，而海内治，故曰：明刑之犹至于无刑也。
From then on, everyone under heaven knew that the Duke of Zhou had used punishment in the royal court, and order was restored within the borders. Therefore, it is said: When fair and strict punishments are used to a certain extent, it is the same as having no punishments.
