Those who ignore the lessons of history, are condemned to repeat them, and again. and again. ad infinitum. ad absurdum.
Nay... if they ignore their GOD...
2 Chronicles 7:14
If my people, who are called by my name,
shall humble themselves,
and pray, and seek my face,
and turn from their wicked ways; ,
then will I hear from heaven,
and will forgive their sin,
and will heal their land.
Here’s a corollary:
Our goal in studying history is not to avoid repeating the mistakes of the past,
but to recognize when the same dumbasses do the same dumbass things resulting in the same disastrous consequences,
we can prepare accordingly.
