You can't live like a Bushman or an Aborigine anymore, so they've got to rethink the whole basis of how they're going to live. Permaculture helps you do that easily.

Permaculture is something with a million heads. It's a way of thinking which is already loose, and you can't put a way of thinking back in the box.

I guess I would know more about permaculture than most people, and I can't define it. It's multi-dimensional - chaos theory was inevitably involved in it from the beginning.

Though the problems of the world are increasingly complex, the solutions remain embarrassingly simple.

Instead of physicists teaching physics, physicists should go home and see what physics applies to their home.

A great many film stars perched on unstable ravine edges in the canyon systems of Los Angeles will, like the cemeteries there, eventually slide down to join their unfortunate fellows in the canyon floors, with mud, cars, and embalmed or living film stars in one glorious muddy mass. We should not lend our talents to creating such spectacular catastrophes.

If you're a simple person today, and want to live simply, that is awfully seditious. And to advise people to live simply is more seditious still.
