Toni Morrison (February 18, 1931 – August 05, 2019)
It may be that the most defining characteristic of our times is that, again, walls and weapons feature as prominently now as they once did in medieval times. Porous borders are understood in some quarters to be areas of threat and certain chaos, and whether real or imagined, enforced separation is posited as the solution. Walls, ammunition — they do work. For a while. But they are major failures over time, as the occupants of casual, unmarked, and mass grave sites haunt the entire history of civilization.
