Letters 21.7

In order that Idomeneus may not be introduced free of charge into my letter, he shall make up the indebtedness from his own account. It was to him that Epicurus addressed the well-known saying urging him to make Pythocles rich, but not rich in the vulgar and equivocal way. “If you wish,” said he, “to make Pythocles rich, do not add to his store of money, but subtract from his desires.”
