And after this manner some one anciently mocked Diogeries, who, in the
depth of winter and quite naked, went embracing an image of snow for a
trial of his endurance: the other seeing him in this position, "Art thou
now very cold?" said he. "Not at all," replied Diogenes. "Why, then,"
pursued the other, "what difficult and exemplary thing dost thou think
thou doest in embracing that snow?" To take a true measure of constancy,
one must necessarily know what the suffering is.

But souls that are to meet with adverse events and the injuries of
fortune, in their depth and sharpness, that are to weigh and taste them
according to their natural weight and bitterness, let such show their
skill in avoiding the causes and diverting the blow. What did King Cotys
do? He paid liberally for the rich and beautiful vessel that had been
presented to him, but, seeing it was exceedingly brittle, he immediately
broke it betimes, to prevent so easy a matter of displeasure against his
servants. In like manner, I have willingly avoided all confusion in my
affairs, and never coveted to have my estate contiguous to those of my
relations, and such with whom I coveted a strict friendship; for thence
matter of unkindness and falling out often proceeds. I formerly loved
hazardous games of cards and dice; but have long since left them off,
only for this reason that, with whatever good air I carried my losses,
I could not help feeling vexed within. A man of honour, who ought to be
touchily sensible of the lie or of an insult, and who is not to take a
scurvy excuse for satisfaction, should avoid occasions of dispute.
I shun melancholy, crabbed men, as I would the plague; and in matters I
cannot talk of without emotion and concern I never meddle, if not
compelled by my duty:

"Melius non incipient, quam desinent."
