There is another underlying
theme, which was borrowed from
the teachings of Taoist science, of
which I was a student, that is
that science not practiced out of a
context of sacredness or
responsibility was a devil's
bargain.

We asked ourselves the question: Is it possible to grow the food needs of a small group of people in a small space without harming the environment and without enormous recourse to external sources of energy and materials on a continuing basis? The whole idea was: Could we design a system that is self-sustainable and capable of functioning as a system?
