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 its game apart. 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 wrangling arrogance, wholly believing and trusting in itself, the capital enemy of discipline and truth. Do but hear them domineer; the first fopperies they utter, 'tis in the style wherewith men establish religions and laws: "Nihil est turpius, quam cognitioni et perceptions assertionem approbationemque praecurrere." ["Nothing is worse than that assertion and decision should precede knowledge and perception."--Cicero, Acad., i. 13.] Aristarchus said that anciently there were scarce seven sages to be found in the world, and in his time scarce so many fools: have not we more reason than he to say so in this age of ours? Affirmation and obstinacy are express signs of want of wit. This fellow may have knocked his nose against the ground a hundred times in a day, yet he will be at his Ergo's as resolute and sturdy as before. You would say he had had some new soul and vigour of understanding infused into him since, and that it happened to him, as to that ancient son of the earth, who took fresh courage and vigour by his fall;
