“My dear friend, clear your mind of cant [excessive thought]. You may talk as other people do: you may say to a man, "Sir, I am your most humble servant." You are not his most humble servant. You may say, "These are bad times; it is a melancholy thing to be reserved to such times." You don't mind the times ...
