Among his epistles of the year there is one which might of itself have sufficed to bring down his name to posterity. This is a long letter, full of advice, to his brother Quintus, who had gone out in the previous year to govern the province of Asia as Proprætor. We may say that good advice could never have been more wanted, and that better advice could not have been given. It has been suggested that it was written as a companion to that treatise on the duties of a candidate which Quintus composed for his brother's service when standing for his Consulship. But I cannot admit the analogy. The composition attributed to Quintus contained lessons of advice equally suitable to any candidate, sprung from the people, striving to rise to high honors in the State. This letter is adapted not only to the special position of Quintus, but to the peculiarities of his character, and its strength lies in this: that while the one brother praises the other, justly praises him, as I believe, for many virtues, so as to make the receipt of it acceptable, it points out faults--faults which will become fatal, if not amended--in language which is not only strong but unanswerable.
The style of this letter is undoubtedly very different from that of Cicero's letters generally--so as to suggest to the reader that it must have been composed expressly for publication whereas the daily correspondence is written "currente calamo," with no other than the immediate idea of amusing, instructing, or perhaps comforting the correspondent. Hence has come the comparison between this and the treatise De Petitione Consulatus. I think that the gravity of the occasion, rather than any regard for posterity, produced the change of style. Cicero found it to be essential to induce his brother to remain at his post, not to throw up his government in disgust, and so to bear himself that he should not make himself absolutely odious to his own staff and to other Romans around him; for Quintus Cicero, though he had been proud and arrogant and ill tempered, had not made himself notorious by the ordinary Roman propensity to plunder his province "What is it that is required of you as a governor?"[245] asks Cicero. "That men should not be frightened by your journeys hither and thither--that they should not be eaten up by your extravagance--that they should not be disturbed by your coming among them--that there should be joy at your approach; when each city should think that its guardian angel, not a cruel master, had come upon it--when each house should feel that it entertained not a robber but a friend. Practice has made you perfect in this. But it is not enough that you should exercise those good offices yourself, but that you should take care that every one of those who come with you should seem to do his best for the inhabitants of the province, for the citizen of Rome, and for the Republic." I wish that I could give the letter entire--both in English, that all readers might know how grand are the precepts taught, and in Latin, that they who understand the language might appreciate the beauty of the words--but I do not dare to fill my pages at such length. A little farther on he gives his idea of the duty of all those who have power over others--even over the dumb animals.[246] "To me it seems that the duty of those in authority over others consists in making those who are under them as happy as the nature of things will allow. Every one knows that you have acted on this principle since you first went to Asia." This, I fear, must be taken as flattery, intended to gild the pill which comes afterward "This is not only his duty who has under him allies and citizens, but is also that of the man who has slaves under his control, and even dumb cattle, that he should study the welfare of all over whom he stands in the position of master!" Let the reader look into this, and ask himself what precepts of Christianity have ever surpassed it.
