This point requires to be illustrated by a story. A certain Pythagoraean bought a fine pair of shoes from a shoemaker; and as they were an expensive piece of work, he did not pay ready money for them. Some time afterwards he came to the shop to pay for them, and after he had long been knocking at the closed door, someone said to him, “Why do you waste your time? The shoemaker whom you seek has been carried out of his house and buried; this is a grief to us who lose our friends forever, but by no means so to you, who know that he will be born again,” jeering at the Pythagoraean. Upon this our philosopher not unwillingly carried his three or four denarii home again, shaking them every now and then; afterwards, blaming himself for the pleasure which he had secretly felt at not paying his debt, and perceiving that he enjoyed having made this trifling gain, he returned to the shop, and saying, “the man lives for you, pay him what you owe,” he passed four denarii into the shop through the crack of the closed door, and let them fall inside, punishing himself for his unconscionable greediness that he might not form the habit of appropriating that which is not his own.
