Eat and drink such an exact quantity as the constitution of thy body
allows of, in reference to the services of the mind.
They that study much ought not to eat as much as those that work hard,
their digestion being not so good.
The exact quantity and quality being found out, is to be kept to
constantly.
Excess in all other things whatever, as well as in meat and drink, is
also to be avoided.
Youth, age, and sick require a different quantity.
And so do those of contrary complexions; for that which is too much
for a phlegmatic man, is not sufficient for a choleric.
The measure of food ought to be (as much as possibly may be) exactly
proportionable to the quality and condition of the stomach, because
the stomach digests it.
That quantity that is sufficient, the stomach can perfectly concoct
and digest, and it sufficeth the due nourishment of the body.
A greater quantity of some things may be eaten than of others, some
being of lighter digestion than others.
The difficulty lies in finding out an exact measure; but eat for
necessity, not pleasure: for lust knows not where necessity ends.
Wouldst thou enjoy a long life, a healthy body, and a vigorous mind,
and be acquainted also with the wonderful works of God, labor in the
first place to bring thy appetite to reason.
