庚信其人及其作品的評價，自古自今，正面評創較多，然清全祖望認為庾信〈哀江南賦〉中「天醉」二句是為「自文」來埋藏自己「失節」的過失。吾意不然，竊以為此乃全氏對於當代的「裂冠毀冕」者感到悲憤，因而借古諷今，故其評論庾信乃基於自身的當代意識，有其時代侷限；再者，庾信身處動亂的時代中，既無鄉可歸，以不能隱居山林，在無可奈何之中，也只能仕北，且當時人對於奉事二朝似乎司空見貫；又全祖望言其「失節」，若無進一步的說明，是不合理的，況且庾信的心始終是傾向梁朝的，他的〈哀江南賦〉處處可以見其鄉關之思，庾信在亂世之中尚且能時時自我反省，這是值得令人稱道的。

So far, although there are more positive evolutions than negative evaluations of Yu, Xin’s character and his literatures, Quan, Zh-Wang from Ching Dynasty thought the two sentences, “Tian Zui”, in Yu, Xin’s “ai Chaing-Nan Fu” are used to hide his immorality. However, three pints are introduced in the paper as follows, the first is Quan, Zu-Wang’s values is influenced by the value of Ching Dynasty; the second is Quan Zu-Wang’s ignorance of Yu, Xin’s situation; the third is Quan, Zu-Wang’s ignorance of the value in the Liang Dynasty. Quan, Zh-Wang’s points about Yu, Xin’s immorality is not objective.
