《三国志·魏书·任苏杜郑仓传》
如果真的让现在朝中任职的官员都是天下人选拔出来的，却不能竭尽他们的才干，不能说是能任用人才；如果不是天下人选拔的，也不能说是会选才任官的。
诚使今朝任职之臣皆天下之选，而不能尽其力，不可谓能使人；若非天下之选，亦不可谓能官人。
If we truly let the officials in the court now be selected by the people in the world, but they can’t do their best, it can’t be said that we can appoint talented people; if they are not selected by people in the world, it can’t be said that we can select talented people to be officials.
