Letter 5 — The Philosopher’s Mean (§5)

“Just as it is a sign of luxury to seek out dainties, so it is madness to avoid that which is customary and can be purchased at no great price. Philosophy calls for plain living, but not for penance; and we may perfectly well be plain and neat at the same time. This is the mean of which I approve; our life should observe a happy medium between the ways of a sage and the ways of the world at large; all men should admire it, but they should understand it also.”
