Do you think a knowledge of history makes us unlikely to repeat it?
Sadly, as much as we learn from history, there are many more who didn’t learn the lesson. There were some atrocious occurrences that took place in our world, but yet we see that many of those atrocities occur again and again in new locations. Whether or not history repeats itself or not depends on who is teaching the lesson, the fervor with which they teach the lesson and the student who is being taught.
I believe that many of the people who teach history have good intentions, yet unless those intentions are hammered home with skill and care, history stands to repeat itself.
