from its depths to the sky."--AEneid, vii. 528.]

Judgment holds in me a magisterial seat; at least it carefully endeavours
to make it so: it leaves my appetites to take their own course, hatred
and friendship, nay, even that I bear to myself, without change or
corruption; if it cannot reform the other parts according to its own
model, at least it suffers not itself to be corrupted by them, but plays

The advice to every one, "to know themselves," should be of important
effect, since that god of wisdom and light' caused it to be written on
the front of his temple,--[At Delphi]--as comprehending all he had to
advise us. Plato says also, that prudence is no other thing than the
execution of this ordinance; and Socrates minutely verifies it in
Xenophon. The difficulties and obscurity are not discerned in any
science but by those who are got into it; for a certain degree of
intelligence is required to be able to know that a man knows not, and we
must push against a door to know whether it be bolted against us or no:
whence this Platonic subtlety springs, that "neither they who know are to
enquire, forasmuch as they know; nor they who do not know, forasmuch as
to inquire they must know what they inquire of." So in this, "of knowing
a man's self," that every man is seen so resolved and satisfied with
himself, that every man thinks himself sufficiently intelligent,
signifies that every one knows nothing about the matter; as Socrates
gives Euthydemus to understand. I, who profess nothing else, therein
find so infinite a depth and variety, that all the fruit I have reaped
from my learning serves only to make me sensible how much I have to
learn. To my weakness, so often confessed, I owe the propension I have
to modesty, to the obedience of belief prescribed me, to a constant
coldness and moderation of opinions, and a hatred of that troublesome and
