We're as clever as we think we are, but we'll be a lot cleverer when we learn to use not just one brain but to pool huge numbers of brains. We're at a level technologically where we can share information and think collectively about our problems. We do it in science all the time - there's no reason why we can't do it in other endeavors.

Medical knowledge and technical savvy are biodegradable. The sort of medicine that was practiced in Boston or New York or Atlanta fifty years ago would be as strange to a medical student or intern today as the ceremonial dance of a !Kung San tribe would seem to a rock festival audience in Hackensack.

The whole dear notion of one's own Self-marvelous old free-willed, free- enterprising, autonomous, independent, isolated island of a Self- is a myth.

If we had better hearing, and could discern the descants of sea birds, the rhythmic tympani of schools of mollusks, or even the distant harmonics of midges hanging over meadows in the sun, the combined sound might lift us off our feet.

It is in our collective behavior that we are most mysterious.

We leave traces of ourselves wherever we go, on whatever we touch.

If an idea cannot move on its own, pushing it doesn't help; best to let it lie there.
