(Sen., Ep. 2.5-6; the LAT 421 and LAT 521 passage was the same, but I supplied more notes on the LAT 421 version of the quiz)
hodiernum hoc est quod apud Epicurum nanctus sum (soleo enim et in aliena castra transire, non tamquam transfuga, sed tamquam explorator): ‘honesta’ inquit ‘res est laeta paupertas’. illa uero non est paupertas, si laeta est; non qui parum habet, sed qui plus cupit, pauper est. quid enim refert quantum illi in arca, quantum in horreis iaceat, quantum pascat aut faeneret, si alieno imminet, si non adquisita sed adquirenda computat? quis sit diuitiarum modus quaeris? primus habere quod necesse est, proximus quod sat est. uale.
"This is today's thought, which I found in Epicurus (for I'm accustomed to cross over even into others’ [philosophical] camps, not like a deserter, but like a scout): "Happy poverty," he says, "is an honorable thing". That in fact is not poverty, if it is happy; the person who has too little is not poor, but he who desires more is. For why does it matter how much lies in a person's coffer, how much in his granaries, how much he pastures or invests, if he has designs on somebody else’s possession, if he calculates not the things he has acquired but the things that he must acquire? You ask what the limit of riches is: the best [limit] is to have what is necessary, second best is to have what is enough. Peace out."
