I think, if we can take any lesson from humanity it would be that, in spite of our best efforts, humans repeat the same mistakes time and time again. Regardless of how many times we err, we still seem to fall into the same holes as our forefathers. If there is any proof of that, I think current events speak to that truth. With all of the violence and hatred and enmity present in the news and politics--I have so little faith in humanity but it is only because they, or we, have done so little to show we are capable of trying harder. Of doing better.I've seen photographs in Asheville, North Carolina that showed descendants of some of these people living in the most ramshackle houses you can imagine. If we could undo history, I wonder if we'd chose to change how the new people treated the old people of the land. It certainly was a trail of tears.
