. . . and further, it is part [of the nature of tyranny] to strive to see that all the affairs of the tyrant are secret, but that nothing is kept hidden of what any subject says or does, rather everywhere he will be spied upon . . . . Also it is part of these tyrannical measures to impoverish the nation so as to bolster the funds available for military defense, and so that the common citizens will be occupied with earning their livelihood and will have neither leisure nor opportunity to engage in conspiratorial acts . . . . Thus, the tyrant is inclined constantly to foment wars in order to preserve his own monopoly of power.
—Aristotle, Politics bk v, xi (350 BCE)
