Let us reasonably accommodate their lives with what is in our power. In
order to this, we should not marry so young that our age shall in a
manner be confounded with theirs; for this inconvenience plunges us into
many very great difficulties, and especially the gentry of the nation,
who are of a condition wherein they have little to do, and who live upon
their rents only: for elsewhere, with people who live by their labour,
the plurality and company of children is an increase to the common stock;
they are so many new tools and instruments wherewith to grow rich.

I married at three-and-thirty years of age, and concur in the opinion of
thirty-five, which is said to be that of Aristotle. Plato will have
nobody marry before thirty; but he has reason to laugh at those who
undertook the work of marriage after five-and-fifty, and condemns their
offspring as unworthy of aliment and life. Thales gave the truest
limits, who, young and being importuned by his mother to marry, answered,
"That it was too soon," and, being grown into years and urged again,
"That it was too late." A man must deny opportunity to every inopportune
action. The ancient Gauls' looked upon it as a very horrid thing for a
man to have society with a woman before he was twenty years of age, and
strictly recommended to the men who designed themselves for war the
keeping their virginity till well grown in years, forasmuch as courage is
abated and diverted by intercourse with women:

"Ma, or congiunto a giovinetta sposa,
E lieto omai de' figli, era invilito
Negli affetti di padre et di marito."

["Now, married to a young wife and happy in children, he was
demoralised by his love as father and husband."
