In that dispute you spoke too contentiously: do not for the future argue with ignorant people:
those who have never been taught are unwilling to learn. You reprimanded that man with more freedom than you ought, and consequently you have offended him instead of amending his ways: in dealing with other cases of the kind, you should look carefully, not only to the truth of what you say, but also whether the person to whom you speak can bear to be told the truth.” Seneca on anger book 3 36
