To Paulinus
1. Your words urge me to write to you but your eloquence deters me from doing so. For as a letter-writer you are almost as good as Tully. You complain that my letters are short and unpolished: this is not due to carelessness but to fear of you, lest writing to you at greater length I should but send you more sentences to find fault with. Moreover, to make a clean breast of it to a good man like you, just about the time the vessels sail for the west, so many letters are demanded of me at once that, if I were to reply to all my correspondents, I should be unable to accomplish my task. Hence it happens that, neglecting the niceties of composition and not revising the work of my secretaries, I dictate whatever first comes into my head. Thus when I write to you I regard you as a friend and not as a critic.
