Letter 29 — On the Critical Condition of Marcellinus (§7)

“It is mountebanks of that sort, for whom it would be more creditable to have left philosophy alone than to traffic in her, whom Marcellinus will throw in my teeth. But I have decided to put up with taunts; he may stir my laughter, but I perchance shall stir him to tears; or, if he persist in his jokes, I shall rejoice, so to speak, in the midst of sorrow, because he is blessed with such a merry sort of lunacy. But that kind of merriment does not last long. Observe such men, and you will note that within a short space of time they laugh to excess and rage to excess.”
