(37) Do not thou, then, my good friend, consider tyrannical power, that most unprofitable of all things, to be a seasonable possession; for neither is punishment disadvantageous, but it is either more beneficial, or at all events not injurious to the good to suffer due punishment, on which account it is expressly comprehended in all laws which are wisely enacted, and those who have established such laws are praised by every one; for what a tyrant is in a people, that is punishment in a law.
(38) When therefore a want and terrible scarcity of virtue seizes upon cities, and when a great abundance of folly overwhelms everything, then God, like the stream of an overflowing torrent, being desirous to wash away all the power and impetuosity of wickedness, in order to purify our race, gives vigour and power to those men who by their natures are fitted to exercise dominion, (39) for without a stern soul wickedness cannot be got rid of. And just as cities keep executioners for the punishment of murderers, and traitors, and sacrilegious persons, not because they approve of the dispositions of the men, but because they have need of the serviceable part of their ministrations; in the same manner the Ruler of this mighty city, the world, appoints tyrants, like ordinary executioners, to be over those cities in which he sees that violence, and injustice, and impiety prevail, and all other kinds of evils in abundance, that he may by these means put an end to their existence. (40) And then he thinks it right to pursue the guilty, as men who have been serving these vices from the impulses of an impure and pitiless soul, with every punishment imaginable, as the ringleaders; for as the power of fire when it has consumed the fuel which was given to it, at last consumes itself also, so also do those who have received supreme power over nations, when they have exhausted the cities and rendered them destitute of inhabitants, at last perish themselves among them, suffering due punishment for all that they have done.
(41) And why should we wonder if God employs the agency of tyrants to get rid of wickedness when widely diffused over cities, and countries, and nations? For he very often uses other ministers, and himself brings about the same end by his own resources, inflicting upon the nation famine, or pestilence, or earthquakes, or any other heaven-sent calamity, by which great and numerous multitudes perish every day, and by which a great portion of the habitable world is made desolate, on account of his care for the preservation of virtue.
(42) Therefore I have now, as I conceive, spoken at sufficient length on the present subject, namely, that no wicked man is happy, by which fact above all others it may be established that there is such a thing as providence; but if you are not thoroughly convinced, then tell me boldly what is the doubt which is still lurking in your mind, for then both of us by labouring together shall be able to see clearly what the real truth is. (43) And after some more arguments, he proceeds thus:–
