Thank you and as many who write..I don't feel like it is me writing any longer!
I
struggled with this for a long time and seem to have stepped on many toes with
earlier attemps. Something is different now and I don't think I can take credit
for
it. for one thing, you and others seem to be listening. Second, there HAS to
be a
widespread frustration with the majority of what is being done under the rubric
of
"complexity research". And finally, as in every revolution, this thing has its
own
momentum!

Yes....and there probably never will be....as we learn to see we will need more
and
more ways to deal with what we see....reduction is no longer an option

It has to be free of "baggage"...that will be hard!

I , for one, never saw chaordic before and therefore it carries no baggage for
me.
