Good manners disappear in proportion as the influence of a Court and an exclusive aristocracy lessens; this decrease can be plainly observed from decade to decade by those who have an eye for public behavior, which grows visibly.
For as laws are necessary that good manners may be preserved, so there is need of good manner that laws may be maintained.
[It., Perche, cosi come i buoni costumi, per mantenersi, hanno bisogno delli leggi; cosi le leggi per ossevarsi, hanno bisogno de' buoni costumi.]
