《汉书·传·叙传上》
德业不会在死后才特别兴盛，功勋若不合时宜也不会彰显，因此圣人的立身行事，忙忙碌碌，来去匆匆。孔子坐着待不到席子温暖，墨子安居也等不到烟囱被熏黑。
夫德不得后身而特盛，功不得背时而独章，是以圣哲之治，栖栖皇皇，孔席不暧，墨突不黔。
De will not be more prosperous after one’s death, achievements will not be emphasized if they are not in accordance with the times, so the way saints live their lives is busy and hurried, coming and going. Confucius could not wait for his mat to get warm when he was sitting down, Mozi could not wait for his chimney to get smoked when he lived in peace.
