Let me quote myself as lead in to reframe my thoughts.
Technological advancement is not a linear progression nor an unbroken zigzag of improvement. But the Dark Ages weren’t the complete setback they are often depicted as. While Europe was struggling, China and the Middle East were still carrying on.
But if what we are taking about is the arc of the moral universe, technology is not really the deciding factor.
Some might think that science played a large role, as a replacement to superstitious thought, and maybe there’s an element to that, but I don’t think that’s the biggest driver.
Rather, I think what has set the arc of the moral universe is the balance of power. When a few bullies have the power, then they use it for their own advantage and screw everyone else. Biggest bully wins.
But as society spreads wealth and power downward, then the moral status of those people start to become more relevant as they grow power as a group.
Consider the transformation from Empire to “democracy” of the Greeks. Power shifted to a larger subset of the population, who took to looking after themselves.
The transformation of the Roman Republic to the Empire shows a reversal of moral concern. Yes, slavery existed in the Republic, but the empire was built on the backs of conquering foreign lands in brutal ways, and the Colloseum was a product of the Empire.
Similarly, look at the history in Europe and the growth of the merchant class distributed wealth beyond the few nobles to larger groups, who in turn pressed for controls on the nobility. The famed Magna Carta is precisely that - the merchant class fighting for some push back against the monarchy.
The Enlightenment is very much part and parcel of the rise of the non-noble merchant that has wealth.
You see it again in the fight of the American colonies for protections for themselves.
While the French Revolution and counter-revolution may feel like a counter trend, understand the fight for a power shift can be brutal to lead to a more humane outcome.
Again, the spread of moral goodness has come largely on the backs of the fight to include more diversity into the holders of power. Women getting the vote, civil rights, secularism and allowing diverse religions inclusivity, gay rights, Me Too, and even the efforts at Trans inclusivity - all are demonstrations of allowing a more diverse set of people to be included in the levers of power, whether it’s voting or running for office or getting to the top of businesses.
And yes, altruistic allies are an integral part, but they have to have their ideals alerted, too.
So currently we are seeing a sad and scary reversion, a reversal of the previous decades of moral improvement. We are seeing a grasp of the formerly priveleged fighting to recreate that privilege by oppression.
My observation is that it seems like the generation that dealt with the last big global catastrophe and the fallout therefrom - WWII to the Cold War - are dying off, and so the lessens of WWII are fading. Some people are beginning to think they should try it.
Thus, the christo- fascist oppressive regime is vying to take control, to throw off all the attacks on their privilege that most of us call progress.
But the saying doesn’t go “the arc of the moral universe is a straight line of improvement,” rather that it bends toward moral goodness over time. But it’s not a smooth arc, it’s a wiggly zigzag that looks like it’s going the other way some times.
I’m hoping the zigzag reverts sooner than later.
