Who does not know that there would be no justice in the world, if there were no wrongs? No courage, if there were no cowards? No continence, if there were no incontinence? No health, if there were no infirmity? No truth, if there were no lying? No good fortune, if there were no misfortunes? Thus, according to Plato,[152] Socrates well says it is surprising that Æsop did not write a fable showing that as God had never been able to join pleasure and pain together, He joined them by their extremities, so that the beginning of the one should be the end of the other; for we see that no joy can give us pleasure, unless sorrow precedes it. Who can hold rest dear, unless he has first felt the hardship of fatigue? Who enjoys food, drink and sleep, unless he has first endured hunger, thirst and wakefulness? Hence I believe that sufferings and diseases were given man by nature not chiefly to make him subject to them (since it does not seem fitting that she who is mother of every good should give us such evils of her own determined purpose), but as nature created health, joy and other blessings,—diseases, sorrows and other ills followed after them as a consequence. In like manner, the virtues having been bestowed upon the world by grace and gift of nature, at once by force of that same bounden opposition, the vices became their fellows by necessity; so that always as the one waxes or wanes, thus likewise must needs the other wax or wane. 3.—So when our old men praise bygone courts for not containing such vicious men as some that our courts contain, they do not perceive that their courts did not contain such virtuous men as some that ours contain; which is no marvel, for no evil is so bad as that which springs from the corrupted seed of good, and hence, as nature now puts forth far better wits than she did then, those who devote themselves to good, do far better than was formerly done, and likewise those who devote themselves to evil, do far worse. Therefore we must not on that account say that those who refrained from evil because they did not know how to do evil, deserved any praise for it; for although they did little harm, they did the worst they could. And that the wits of those times were generally inferior to those of our time, can be well enough perceived in all that we see of those times, both in letters and in pictures, statues, buildings, and every other thing.
