When I was still a boy at school, I heard that this Greek saying, which I here set down, was uttered by Musonius the philosopher, and because the sentiment is true and striking as well as neatly and concisely rounded out, I was very happy to commit it to memory. "If one accomplishes some good though with toil, the toil passes, but the good remains; if one does something dishonorable with pleasure, the pleasure passes, but the dishonor remains."
Afterwards I read that same sentiment in a speech of Cato's which was delivered at Numantia to the knights. Although it is expressed a little less compactly and concisely as compared with the Greek which I have quoted, yet because it is earlier and more ancient, it may well seem more impressive. The words from his speech are the following: "Consider this in your hearts: if you accomplish some good attended with toil, the toil will quickly leave you; but if you do some evil attended with pleasure, the pleasure will quickly pass away, but the bad deed will remain with you always."[1]
1 Aulus Gellius who relates this tale was born at least a quarter of a century after Musonius' death.
