Not commerce as we now know it

“It will, moreover, befit a gentleman to be at the same time liberal in giving and not inconsiderate in exacting his dues, but in every business relation — in buying or selling, in hiring or letting, in relations arising out of adjoining houses and lands — to be fair, reasonable, often freely yielding much of his own right, and keeping out of litigation as far as his interests will permit and perhaps even a little farther. For it is not only generous occasionally to abate a little of one’s rightful claims, but it is sometimes even advantageous. We should, however, have a care for our personal property, for it is discreditable to let it run through our fingers; but we must guard it in such a way that there shall be no suspicion of meanness or avarice. For the greatest privilege of wealth is, beyond all peradventure, the opportunity it affords for doing good, without sacrificing one’s fortune.” – Marcus Tullius Cicero, De Officiis (trans. Miller)
