The wife or husband, whose affections are estranged, neglect their house, avoid it, and deprive it, as much as they can, of its revenues or income, to expend them with the object of their affections; hence arise quarrels, scandal, lawsuits, the neglect of their children and servants, and at last the plundering and ruin of the whole family; without reckoning that the adulterous woman commits a most grievous theft, in giving to her husband heirs of foreign blood, who deprive his real children of their legitimate portion.
Q.What is filial love?
A.It is, on the side of children, the practice of those actions useful to themselves and to their parents.
Q.How does the law of nature prescribe filial love?
A.By three principal motives: 1.

By sentiment; for the affectionate care of parents inspires, from the most tender age, mild habits of attachment.
2.

By justice; for children owe to their parents a return and indemnity for the cares, and even for the expenses, they have caused them.
3.

By personal interest; for, if they use them ill, they give to their own children examples of revolt and ingratitude, which authorize them, at a future day, to behave to themselves in a similar manner.
Q.Are we to understand by filial love a passive and blind submission?
A.No; but a reasonable submission, founded on the knowledge of the mutual rights and duties of parents and children; rights and duties, without the observance of which their mutual conduct is nothing but disorder.
Q.Why is fraternal love a virtue?
A.Because the concord and union, which result from the love of brothers, establish the strength, security, and conservation of the family: brothers united defend themselves against all oppression, they aid one another in their wants, they help one another in their misfortunes, and thus secure their common existence; while brothers disunited, abandoned each to his own personal strength, fall into all the inconveniences attendant on an insulated state and individual weakness.

This is what a certain Scythian king ingeniously expressed when, on his death-bed, calling his children to him, he ordered them to break a bundle of arrows.
