Is it possible for humany to experience a shift in conscioussness where we can experience inner peace and happiness no matter outer circumstances? Where we would feel connected to each other and by nature being interested in growth for each other and our environment?

Is it possible to have such evolution happen without, but not excluding, religious and philosophical inclinations?

I came here following a link hoping to find the Mont Fleur scenarios which mapped out a peaceful transition from apartheid for South Africa. I found the article under related documents. However, when I clicked on the link I got a 404 error--page unavailable.
