A while back I read the saying "he who is in a rush shall walk slowly". I have seen it be attributed to Confucius (https://www.wer-weiss-was.de/t/redewendung-wer-es-eilig-hat-soll-langsam-gehen/8457422 https://www.quotez.net/german/konfuzius.htm) sometimes, but never in any academic reference.
Who is the author of the sentence and where was it written down first?
