Quantum elargiri deceat: quern te Deus esse
Jussit, et humana qua parte locatus es in re;
Quid sumus, et quidnam victuri gignimur."

["Learn what it is right to wish; what is the true use of coined
money; how much it becomes us to give in liberality to our country
and our dear relations; whom and what the Deity commanded thee to
be; and in what part of the human system thou art placed; what we
are ant to what purpose engendered."--Persius, iii. 69]

what it is to know, and what to be ignorant; what ought to be the end and
design of study; what valour, temperance, and justice are; the difference
betwixt ambition and avarice, servitude and subjection, licence and
liberty; by what token a man may know true and solid contentment; how far
death, affliction, and disgrace are to be apprehended;

"Et quo quemque modo fugiatque feratque laborem."

["And how you may shun or sustain every hardship."
--Virgil, AEneid, iii. 459.]

by what secret springs we move, and the reason of our various agitations
and irresolutions: for, methinks the first doctrine with which one should
season his understanding, ought to be that which regulates his manners
and his sense; that teaches him to know himself, and how both well to dig
and well to live. Amongst the liberal sciences, let us begin with that
which makes us free; not that they do not all serve in some measure to
the instruction and use of life, as all other things in some sort also
do; but let us make choice of that which directly and professedly serves
to that end. If we are once able to restrain the offices of human life
within their just and natural limits, we shall find that most of the
sciences in use are of no great use to us, and even in those that are,
that there are many very unnecessary cavities and dilatations which we
had better let alone, and, following Socrates' direction, limit the
course of our studies to those things only where is a true and real
utility:

"Sapere aude;
Incipe; Qui recte vivendi prorogat horam,
Rusticus exspectat, dum defluat amnis; at ille
Labitur, et labetur in omne volubilis oevum."

["Dare to be wise; begin! he who defers the hour of living well is
like the clown, waiting till the river shall have flowed out: but
the river still flows, and will run on,
