Filial obedience is the first and greatest requisite of a state; by this we become good subjects to our emperors, capable of behaving with just subordination to our superiors, and grateful dependents on heaven; by this we become fonder of marriage, in order to be capable of exacting obedience from others in our turn; by this we become good magistrates, for early submission is the truest lesson to those who would learn to rule. By this the whole state may be said to resemble one family.
