Lessons About History occur on a moving rather than static landscape of constant change such as a population more likely to be living in a democracy in 2020 than 200 years ago, people much less likely to be living in poverty, people much healthier with less disease, a population which is much more literate, a population much more able to read and thus understand surroundings, and so on.
