A quote
“Yes, but I do not know,” you say, “how the man you speak of will endure poverty, if he falls into it suddenly.” Nor do I, Epicurus, know whether the poor man you speak of will despise riches, should he suddenly fall into them; accordingly, in the case of both, it is the mind that must be appraised, and we must investigate whether your man is pleased with his poverty, and whether my man is displeased with his riches. Otherwise, the cot-bed and the rags are slight proof of his good intentions, if it has not been made clear that the person concerned endures these trials not from necessity but from preference.
