We began, untold eons ago, as a simple tribal species. We existed separate from each other, largely. Our entire existence was bounded by a few miles here, and there. That changed. Once we domesticated animals, (mostly horses, donkeys, asses) to our use, we ranged further. Then we set sail. We scraped the seas, slowly, it is certain. Once the Industrial Age dawned we set sail again, but this time in ships that had motive power delivered by steam. Transiting the seas took a few weeks, then a few days, rather than months. We surged across the landscape on trains, similarly powered. And when the Twentieth Century dawned, we took to the air. We made it possible, even in those early times, for a person to cover the waist of the world in a few days.
We have entered into a phase of global existence that challenges us all to shift, change, and morph into something new. I have no idea what that is going to look like. I would be a supreme fool to say with certainty that I do. What I feel I can say with confidence is this. We are reaching a point where old ideas of nation, religion, and society are losing their grip. If we really mean to become this global society, this single human family that 2000 years ago Alexander imagined, then there are things we must let go of.
As a small example, This necklace I made for myself had items in it that come from two different continents and even more cultural sources. But, if I had bought this at a shop, I might not know it's provenance. The pendant is a piece of antique Czech glass, some beads are from Africa, some from Japan, and some from Russia.
