Tracy Marks The idea of collective loss of memory is worth exploring here. Humanity keeps making the same mistakes over and over -- e.g. getting into a war believing that it will be short, we will get in and out and triumph etc. OR scapegoating a group, race or religion. It's as if we don't really learn from the past - maybe in part though because each new generation doesn't live through what the previous generation experienced and has to learn for itself.
