Letter 42 — On Values (§6)

“Therefore, with regard to the objects which we pursue, and for which we strive with great effort, we should note this truth; either there is nothing desirable in them, or the undesirable is preponderant. Some objects are superfluous; others are not worth the price we pay for them. But we do not see this clearly, and we regard things as free gifts when they really cost us very dear.”
