M. Tullius Cicero, Letters to his brother Quintus
Evelyn Shuckburgh, Evelyn S. Shuckburgh, Ed.

But if they will fairly reconcile themselves to the existence and name of publican, all the rest may be made to appear to them in a less offensive light by your skill and prudence. They may, in making their bargains with the publicani, not have regard so much to the exact conditions laid down by the censors as to the convenience of settling the business and freeing themselves from farther trouble. You also may do, what you have done splendidly and are still doing, namely, dwell on the high position of the publicani, and on your obligations to that order, in such a way as—putting out of the question all considerations of your imperium and the power of your official authority and dignity—to reconcile the Greeks with the publicani; and to beg of those, whom you have served eminently well, and who owe you everything, to suffer you by their compliance to maintain and preserve the bonds which unite us with the publicani. But why do I address these exhortations to you, who are not only capable of carrying them out of your own accord without anyone's instruction, but have already to a great extent thoroughly done so? For the most respectable and important companies do not cease offering me thanks daily, and this is all the more gratifying to me because the Greeks do the same. Now it is an achievement of great difficulty to unite in feeling things which are opposite in interests, aims, and, I had almost said, in their very nature. But I have not written all this to instruct you—for your wisdom requires no man's instruction—but it has been a pleasure to me while writing to set down your virtues, though I have run to greater length in this letter than I could have wished, or than I thought I should.
