You are not obliged to assault people with discourses that are out of their road, when you see that their received notions must prevent your making an impression upon them: you ought rather to cast about and to manage things with all the dexterity in your power, so that, if you are not able to make them go well, they may be as little ill as possible; for, except all men were good, everything cannot be right, and that is a blessing that I do not at present hope to see.
