The History of Science "from Outside of the Bun." Great article, important
topic, and a curious coincidence. I just happened to be [re-]reading about
al-Hassan Ibn al-Haytham (known as "Alhazen" to the West) last night - it
must be indoor/armchair Permaculture for many of us this time of year. The
article below is right on. I am reading a great book by Amherst College
Professor, Dick Teresi, "Lost Discoveries, the Ancient Roots of Modern
Science - from Babylonians to the Maya." I would highly recommend it.

It describes well the 1000 years or so when my European ancestors were in
the primitive, crude, brutal Dark/Middle Ages and the Middle East and Arabs
were having a fine time preserving/advancing/using science. And it also goes
back to the Sumerians (where the Greeks got a lot of their stuff) and the
Bible got the root of its story of Noah (via the Epic of Gilgamesh) and
swings wider to include China, India, Oceania, and America. It is full of
good ancient, indigenous, non-Western science 500 to thousands of years
before the European Renaissance and Enlightenment. A good re-titling might
be "While We Were Sleeping."

To me, this subject area is humbling - modern science and its Anglo
predecessors did not invent/discover everything, did not and do not have all
the answers, and owe a great debt of humble gratitude to these many, many
other folks. The ancients and indigenous have given us great gifts of
science, but they were mixed, debated, and improved by philosophy and
spirituality. It was easy to see and talk about the three together. Today,
Permaculture, as a philosophy, does a good job of putting science/technology
together with practical, old-school, local techniques, and fits very
comfortably with many types of spirituality. To me this is a "Road That Must
Be Travelled." in our future and Permaculture education and demonstration is
the best vehicle I know of to make the journey.

My wish for 2009, this decade, this century is to bring a more humble
Science together with Spirituality and Philosophy, bringing Religion along
if necessary and well-behaved. It would also be great if each could study a
bit of the others' history and ideas while the discussions are starting up.
I really believe that Permaculture and Permaculturists can make a major
contribution here. My vision of today is: Science, a boat without a rudder;
Philosophy, a navigator without a boat; Religion, a rudder without a boat,
and all are high and dry but near an ocean of Spirituality. Perhaps together
there would be a "Boat That Would Float."

Thanks for the catalyst, Lawrence. Happy Permaculture New Year to all.
