People aren’t that different from those in the past. We all have the same motivations and needs. Your great-great-great-grandparents and their governments had to overcome their own versions of the same problems that we wake up worrying about. Many of our problems aren’t new yet we still make the same mistakes.
We have come a long way in coping with the problems of terrorism and disease, but have been less successful in solving or avoiding problems that are caused by greed and land. The same religious beliefs have been around for centuries yet now they are being used as an excuse for war.
If we are ever going to stand a chance of saving ourselves then we need to start looking at the causes and solutions to past problems that are similar or close to those we face today. This hopefully will help us to avoid making the same mistakes again.
