The more one knows about history, the less shocked one is by current events.

True, history does not always repeat itself, but it often rhymes.
"He who does not know his history is condemned to repeat it".
But the fact that things have to once again turn to become the worst versions of themselves means that at one point since the historical event everyone had become the best versions of themselves. We are turning the tide
Is a "one knows" like a zap and when you zap history the future gets dull and stops shocking you?
