The
greatstory.org link has a lot of "ways of looking at things" that I hope more people in our culture will eventually become aware of. (rather damn sooner than later) I have a few minor quibbles, but the good stuff well outweighs them. It sounds like they may have read some Daniel Quinn along the way.
On the evolving edge tip: Yes, as long as we don't believe that our culture is on the evolving edge of humanity. ("our culture" means the one that keeps food under lock and key) As mentioned at thegreatstory.org, humans don't represent the end of evolution. Contrary to what our culture murmurs to us constantly, humans aren't the antagonist in the final chapter of the story of creation. We can all do an experiment to illustrate how prevalent that myth is by asking a few people to relate the story of creation beginning at the moment the universe was born devoid of any religious dogma or mythology - totally scientific, iow. Nearly invariably, their story will end with "then humans appeared". Unwarranted arrogance there, eh?
Humans have a responsibility to the evolving community of life because we are the
first species on earth capable of complex abstract thinking, social organization, and of course technological invention. Our responsibility is to not be the last.
