The doctrine of the mean (the epithet 'golden' is un-Aristotelian) regularly occurs in later writers as a piece of moral advice -- a recipe or rule reminding us to 'observe the mean', to be moderate in all things and to avoid excess and deciciency. (If the doctrine urges us not to drink too much wine, it equally urges us not to drink too little -- but that is something which the moralizers usually find it prudent to ignore.)
