The history which I am writing furnishes but too many examples of the latter sort. With respect to the Persians, it will appear, by what is said of their kings, that those princes, whose power has no other bounds than those of their will, often abandon themselves to all their passions; that nothing is more difficult than to resist the illusions of a man’s own greatness, and the flatteries of those that surround him; that the liberty of gratifying all one’s desires, and of doing evil with impunity, is a dangerous situation; that the best dispositions can hardly withstand such a temptation; that even after having begun their career favourably, they are insensibly corrupted by softness and effeminacy, by pride, and their aversion to sincere counsels; and that it rarely happens they are wise enough to consider, that, when they find themselves exalted above all laws and restraints, they stand then most in need of moderation and wisdom, both in regard to themselves and others; and that in such a situation they ought to be doubly wise, and doubly strong, in order to set bounds within, by their reason, to a power that has none without. With respect to the Grecians, the Peloponnesian war will show the miserable effects of their intestine divisions, and the fatal excesses into which they were led by their thirst of dominion: scenes of injustice, ingratitude, and perfidy, together with the open violation of treaties, or mean artifices and unworthy tricks to elude their execution. It will show, how scandalously the Lacedæmonians and Athenians debased themselves to the barbarians, in order to beg aids of money from them: how shamefully the great deliverers of Greece renounced the glory of all their past labours and exploits, by stooping and making their court to haughty and insolent satrapæ, and by going successively, with a kind of emulation, to implore the protection of the common enemy, whom they had so often conquered; and in what manner they employed the succours they obtained from them, in oppressing their ancient allies, and extending their own territories by unjust and violent methods. On both sides, and sometimes in the same person, we shall find a surprising mixture of good and bad, of virtues and vices, of glorious actions and mean sentiments; and sometimes, perhaps, we shall be ready to ask ourselves, whether these can be the same persons and the same people, of whom such different things are related: and whether it be possible, that such a bright and shining light, and such thick clouds of smoke and darkness, can proceed from the same source?
