Plutarch De virtute et vitio 4

[4] Heap up gold, amass silver, build stately promenades, fill your house with slaves and the city with your debtors; unless you lay level the emotions of your soul, put a stop to your insatiate desires, and quit yourself of fears and anxieties, you are but decanting wine for a man in a fever, offering honey to a bilious man, and preparing tid-bits and dainties for sufferers from colic or dysentery, who cannot retain them or be strengthened by them, but are only brought nearer to death thereby. Does not your observation of sick persons teach you that they dislike and reject and decline the finest and costliest viands which their attendants offer and try to force upon them; and then later, when their whole condition has changed, and good breathing, wholesome blood, and normal temperature have returned to their bodies, they get up and have joy and satisfaction in eating plain bread with cheese and cress? ¹ It is such a condition that reason creates in the soul. You will be contented with your lot if you learn what the honourable and good is. You will be luxurious in poverty, and live like a king, and you will find no less satisfaction in the care-free life of a private citizen than in the life connected with high military or civic office. If you become a philosopher, you will live not unpleasantly, but you will learn to subsist pleasantly anywhere and with any resources. Wealth will give you gladness for the good you will do to many, poverty for your freedom from many cares, repute for the honours you will enjoy, and obscurity for the certainty that you shall not be envied.
