These philosophers say that it is not enough to have the soul seated in
a good place, of a good temper, and well disposed to virtue; it is not
enough to have our resolutions and our reasoning fixed above all the
power of fortune, but that we are, moreover, to seek occasions wherein to
put them to the proof: they would seek pain, necessity, and contempt to
contend with them and to keep the soul in breath:

"Multum sibi adjicit virtus lacessita."

["Virtue is much strengthened by combats."
or: "Virtue attacked adds to its own force."
--Seneca, Ep., 13.]

'Tis one of the reasons why Epaminondas, who was yet of a third sect,
--[The Pythagorean.]--refused the riches fortune presented to him by
very lawful means; because, said he, I am to contend with poverty, in
which extreme he maintained himself to the last. Socrates put himself,
methinks, upon a ruder trial, keeping for his exercise a confounded
scolding wife, which was fighting at sharps. Metellus having, of all the
Roman senators, alone attempted, by the power of virtue, to withstand the
violence of Saturninus, tribune of the people at Rome, who would, by all
means, cause an unjust law to pass in favour of the commons, and, by so
doing, having incurred the capital penalties that Saturninus had
established against the dissentient, entertained those who, in this
extremity, led him to execution with words to this effect: That it was a
thing too easy and too base to do ill; and that to do well where there
was no danger was a common thing; but that to do well where there was
danger was the proper office of a man of virtue. These words of Metellus
very clearly represent to us what I would make out, viz., that virtue
refuses facility for a companion; and that the easy, smooth, and
descending way by which the regular steps of a sweet disposition of
nature are conducted is not that of a true virtue; she requires a rough
and stormy passage; she will have either exotic difficulties to wrestle
with, like that of Metellus, by means whereof fortune delights to
interrupt the speed of her career, or internal difficulties, that the
inordinate appetites and imperfections of our condition introduce to
disturb her.

I am come thus far at my ease; but here it comes into my head that the
soul of Socrates, the most perfect that ever came to my knowledge, should
by this rule be of very little recommendati
