"To discover to the world something which deeply concerns it, and of which it was previously ignorant; to prove to it that it had been mistaken on some vital point of temporal or spiritual interest, is as important a service as a human being can render to his fellow creatures..."
John Stuart Mill, "On Liberty"
It's hard to imagine today, but the East, what we refer to now as the Middle East, was once a pinnacle of civilization. Like all great civilizations, it struggled with conflict between personal values and its laws, about succession and tribalism and security. It evolved a form of rule in the Islamic world that lasted for almost 1300 years..by any account a pretty good run.
Today that rule, what was once called the Caliphate, has been morphed into something far removed from it’s original meaning. As such, it has become a word that embodies the worst, not the best of civilization. Esteemed historian Hugh Kennedy puts all of this in perspective in Caliphate: The History of an Idea.
