《魏书·列传·卷四十一》
对于国家来说有不许继承爵位的做法，是因为看重列爵的缘故，特为此立制，因天之所绝，推而除之罢了，哪能够再反过来报以刑赏？
于国所以不袭者，重列爵，特立制，因天之所绝，推而除之耳，岂复报对刑赏？
For the country, there is the practice of not inheriting titles, because the emphasis is on the establishment of ranks, and special regulations are made for this purpose. Since heaven has cut off the descendants, we should push them out and get rid of them. How can we reciprocate with punishment and reward?
