'But that thou mayst not think that I wage implacable warfare against Fortune, I own there is a time when the deceitful goddess serves men well—I mean when she reveals herself, uncovers her face, and confesses her true character. Perhaps thou dost not yet grasp my meaning. Strange is the thing I am trying to express, and for this cause I can scarce find words to make clear my thought. For truly I believe that Ill Fortune is of more use to men than Good Fortune. For Good Fortune, when she wears the guise of happiness, and most seems to caress, is always lying; Ill Fortune is always truthful, since, in changing, she shows her inconstancy. The one deceives, the other teaches; the one enchains the minds of those who enjoy her favour by the semblance of delusive good, the other delivers them by the knowledge of the frail nature of happiness. Accordingly, thou mayst see the one fickle, shifting as the breeze, and ever self-deceived; the other sober-minded, alert, and wary, by reason of the very discipline of adversity. Finally, Good Fortune, by her allurements, draws men far from the true good; Ill Fortune ofttimes draws men back to true good with grappling-irons. Again, should it be esteemed a trifling boon, thinkest thou, that this cruel, this odious Fortune hath discovered to thee the hearts of thy faithful friends—that other hid from thee alike the faces of the true friends and of the false, but in departing she hath taken away her friends, and left thee thine? What price wouldst thou not have given for this service in the fulness of thy prosperity when thou seemedst to thyself fortunate? Cease, then, to seek the wealth thou hast lost, since in true friends thou hast found the most precious of all riches.'

"But, lest you think I wage an inexorable war against fortune, there is a time when she, that deceiver, deserves well of men—namely, when she reveals herself, when she uncovers her face and declares her ways. Perhaps you do not yet understand what I mean. It is a strange thing I am eager to say, and so I can hardly unfold my thought in words. For I think that adverse fortune profits men more than prosperous. The latter always lies under the appearance of happiness, when she seems kind; the former is always true, when she shows herself unstable by her changing. The one deceives, the other instructs; the one binds the minds of those who enjoy her with a falsehood under the appearance of goods, the other frees them by the knowledge of how fragile happiness is. And so you may see the one windy, flowing, and always ignorant of herself, the other sober, well-girt, and made prudent by the very exercise of adversity. Finally, prosperity, by her flatteries, draws men astray from the true good; adversity for the most part draws them back by a hook to true goods. Or do you think this should be reckoned among the least of things—that this harsh, this terrible fortune has uncovered for you the minds of your faithful friends? She has sorted out for you the sure faces of your companions from the doubtful ones; departing, she took her own away and left you yours. How much would you have paid for this while you were untouched and, as you seemed to yourself, fortunate? Now you complain of lost wealth: you have found friends, the most precious kind of riches."
