Plato: “A tyrant must always be provoking war… But all this lays him open to unpopularity… So won’t some of the bolder characters among those who helped him to power, and now hold positions of influence, begin to speak freely to him and to each other, and blame him for what is happening?...Then, if he is to retain power, he must root them out, all of them, till there’s not a man of any consequence left, whether friend or foe…So he must keep a sharp eye out for men of courage or vision or intelligence or wealth; for, whether he likes it or not, it is his happy fate to be their constant enemy and to intrigue until he has purged them from the state… Then… people will find out soon enough what sort of a beast they’ve bred and groomed for greatness. He’ll be too strong for them to turn out” (Republic, Book VIII, 567a – 569a)
