Lucretius, De Rerum Natura 3.1053-1075

“When people seem to feel that there is a weight
On their minds, which wears them out with its pressure–
If they were able to understand where it comes from and what causes
So great a burden of misery to press upon their chests,
They would hardly live their lives as we now see most do:
Each person does not know what he wants and always seeks
To change his place as if he could possibly slough of the burden.

Often this man departs from the doors of his great home,
When he has tired of being there, only to return suddenly
When he comes to believe that he is no better off outside.
He rushes out driving his ponies heedlessly to his villa
As if he were bringing crucial help to a burning home.
Yet when he arrives and crosses the threshold of the house,
He either falls into a deep sleep or pursues oblivion,
Or he even rushes to visit the city again,
This is the way each man flees from himself, but it is his self
That it is impossible to escape, so he clings to it thanklessly and hates.

He does this because he is a sick man who is ignorant of the cause.
If he knew the cause, he would abandon all these things
And begin his first study of the nature of things,
Since the problem is not that of a single hour but of eternal time—
In what state we must understand that all time will pass
For mortal man after the death that awaits all of us.”

Si possent homines, proinde ac sentire videntur
pondus inesse animo, quod se gravitate fatiget,
e quibus id fiat causis quoque noscere et unde
tanta mali tam quam moles in pectore constet,
haut ita vitam agerent, ut nunc plerumque videmus
quid sibi quisque velit nescire et quaerere semper,
commutare locum, quasi onus deponere possit.
exit saepe foras magnis ex aedibus ille,
esse domi quem pertaesumst, subitoque [revertit>,
quippe foris nihilo melius qui sentiat esse.
currit agens mannos ad villam praecipitanter
auxilium tectis quasi ferre ardentibus instans;
oscitat extemplo, tetigit cum limina villae,
aut abit in somnum gravis atque oblivia quaerit,
aut etiam properans urbem petit atque revisit.
hoc se quisque modo fugit, at quem scilicet, ut fit,
effugere haut potis est: ingratius haeret et odit
propterea, morbi quia causam non tenet aeger;
quam bene si videat, iam rebus quisque relictis
naturam primum studeat cognoscere rerum,
temporis aeterni quoniam, non unius horae,
ambigitur status, in quo sit mortalibus omnis
aetas, post mortem quae restat cumque manendo.
