英漢詞典釋義
n.
(古希臘)貝殼流放法
There is yet some good in public envy, whereas in private, there is none. For public envy, is as an ostracism, that eclipseth men, when they grow too great. And therefore it is a bridle also to great ones, to keep them within bounds.雖說私人間的嫉妒有百害而無一利，但公眾的嫉妒卻還有一點好處，因為它就像陶片放逐法，可除去那些位高專權者，所以它對其他大人物亦是一種制約，可使他們循規蹈矩。
