I swam across the rocks and compared myself favorably with the sars. To swim fishlike, horizontally, was the logical method in a medium eight hundred times denser than air. To halt and hang attached to nothing, no lines or air pipe to the surface, was a dream. At night I had often had visions of flying by extending my arms as wings. Now I flew without wings. (Since that first aqualung flight, I have never had a dream of flying.)

It is certain that the study of human psychology, if it were undertaken exclusively in prisons, would also lead to misrepresentation and absurd generalizations.

In order to stabilize world population, we must eliminate 350,000 per day.

We have to prepare for what life could become in 40 years. We need to outline what is possible and what is impossible with the non-renewable resources of the Earth.

The idea of a group of elders is that, in past civilizations, they have linked worlds; the other world was also present in this one. There is also the argument that elders have "experience."

What we are facing tomorrow requires the force of imagination, not wisdom from yesterday.

I believe that national sovereignties will shrink in the face of universal interdependence.
