Original translation
“No longer talk at all about the kind of man that a good man ought to be, but be such.”
Translated by George Long, 1862
“Time is like a river made up of the events which happen, and a violent stream; for as soon as a thing has been seen, it is carried away, and another comes in its place, and this will be carried away too.”
― Marcus AureliusMeditations (Book VI, Section 51)
