Marcus Aurelius
Meditations 7.1
What is badness? It is that which thou hast often seen. And on the occasion of everything which happens keep this in mind, that it is that which thou hast often seen. Everywhere up and down thou wilt find the same things, with which the old histories are filled, those of the middle ages and those of our own day; with which cities and houses are filled now. There is nothing new: all things are both familiar and short-lived.
Marcus Aurelius, Meditations 7.1, translated by George Long
What is vice? A familiar sight enough. So in everything that befalls have the thought ready: This is a familiar sight. Look up, look down, everywhere thou wilt find the same things, whereof histories ancient, medieval, and modern are full; and full of them at this day are cities and houses. There is no new thing under the sun. Everything is stereotyped, everything fleeting.
Marcus Aurelius, Meditations 7.1, translated by C. R. Haines
