For late nighters, another thought from Rubicon: The Last Years of the Roman Republic. This passage describes the early 1st century BC, a time when the Roman Republic extended its power through tacit support of pet kings (and knocked off their rivals, when necessary) rather than direct rule.
Philosophers, like every other legacy of the Athenian golden age, had become mere adjuncts of the Roman service industry. Those who did particularly well out of Roman patronage had long since learned to cut the cloth of their speculations accordingly. Typical was the age’s most celebrated polymath, Posidonius.
Although he had studied in Athens, Posidonius was widely traveled, and rationalized what he observed in Rome’s provinces – rather optimistically – as a commonwealth of man. […] In the new order that the Republic was bringing to the world, Posidonius somehow managed to catch a reflection of the order of the universe. He argued that it was the moral duty of Rome’s subjects to accept such a dispensation. Differences of culture and geography would soon dissolve. History was coming to an end.
Francis Fukuyama Posidonius was right! History did end and the Roman Republic lasted forever.
