I think you are projecting the narriative of Progres (TM) onto the accurate facts you are presenting. i.e. the Catholic Church did not invent checks and balances. They used to have those in the Old Republic, but those were abandoned after the Roman Civilization reached the appex of its, let's call it cultural vitality. I see the authoritarism of the Caesars as a symptom of Rome having run out of fresh ideas, they "jumped the shark" if you will. I agree the Middle Ages were not some sort of dystopian hell. There was a Dark age after (or more precisely, around) the time when Rome fell. Those were hungry and dangerous times, and the people that survived were more impoverished (both in the material and the intelectual sense) than their forefathers, but survive they did. The Middle Ages is what resulted when the survivors rebuilt society out of the wreckage. I agree that many former Roman institutions were repurposed during those times, but I do not see this as a way of purposeful progress. Rather, those obsolete institutions were salvaged and repurposed by the new Medieval society for its own needs. Superficially they look like a continuation of the same, but they were successful because they had a different cultural sensitivity, they had fresh ideas now, with their own new values and their own expectations of how things should be. And they pushed those in directions that no old Roman philosopher would've been able to imagine. I think people tend to conflate Middle Ages with "Dark age" because the Middle Ages ended in a relatively mild collapse. The (Christian) Reformation and the Enlightenment allowed much of the cultural treasures of the past age to be preserved, but also caused warfare, famine, dislocation of whole nations, etc. Again, hungry and dangerous times, and again the survivors picked up the pieces and build the world we know today. Our world looks superficialy like a continuation of the Renaissance, but it is not. The Renaissance is the apex of the cultural vitality of the Middle Ages, and our own World's foundations rest upon many of its repurposed ideas and institutions. But it had ideas and values of our own, and our forefathers took that in directions that no Scholastic monk would have ever imagined. So, you can see, we are no closer to a future of endless joy, anymore than any other society that inhabited this planet ever did. We are going our own way around the cycle, and clearly we have ran out of fresh ideas ourselves. I will not pretend to be subtle, our times will be on the down slope and depending on how fast this proceeds we ourselves or our children may end up in one of those dark ages (no uppercase, thank you very much) where hungry and dangerous is the norm. And then others will come and pick up the pieces. I guess what I expect to acomplish in life is to leave behind some cultural artifacts in good working order; and I hope that, one or two centuries from now, some smart guy will pick those up and push them in directions that I'd never be able to imagine.
