13 She mourns for her husband with sufficient devotion who preserves her modesty and does not give up her constancy. The best duties to discharge to the departed are that they live in our memories and continue in our affection. She has not lost her husband who manifests her chastity, nor is she widowed as regards her union who has not changed her husband's name. Nor have you lost the heir when you assist the joint-heir, but in exchange for a successor in perishable things you have a sharer in things eternal. You have one to represent your heir, pay to the poor what was due to the heir, that there may remain one to survive, not only the old age of father or mother, but your own life. You leave your successor all the more, if his share conduce not to luxury in things present, but to the purchasing of things to come.
