Epistulae ad Lucilium 16.7-8

“I consider as my own whatever is well-put by anyone else. Here too is a sentiment expressed by Epicurus: ‘If you live according to nature, you will never be poor; if you live according to fancy, you will never be rich.” For nature desires very little, but the desires of fancy are boundless.”

quicquid bene dictum est ab ullo, meum est. istud quoque ab Epicuro dictum est: ‘si ad naturam vives, numquam eris pauper: si ad opiniones, numquam eris dives.’ exiguum natura desiderat, opinio immensum.
