This may be the finest meta-analysis of this phenomenon I've read to date. Thank you. In particular: >> once insights are established they also suffer from a decay rate (proportional to the magnitude of disruptions into the cohesive fabric of societies) - if not activley reinforced - and then have to be relearned (the hard way) after the turbulent times of societal changes subside. I'm intrigued - although not completely sold - by this idea that rather than a pendulum swinging too far one way and too far the other, we're actually regressing and forgetting hard-won liberties (and the skills most people need to reason with why those liberties are necessary). If that's so, it's more like we're entering a mini (or who knows, not so mini) dark age, right?
