Predicting the future.

Mar 2012
What can we predict by understanding the past.

Here are just a few I can think of, feel free to add more.

Civilization will always have a downfall. While in the written records it'll appear as a total collapse it actually is a process that takes generations, with the exception of the elite it is not seen as devastating at the time when it happens.

People will hold on to institutions long after there needed or relevant as a default way of thinking. Think Holy roman empire.

Mass demographics generally are the biggest indicator of change.
