I did my masters in elementary particles. But the foundations of elementary particles is quantum theory and there were too many conceptual problems around quantum theory that I couldn't live with. So I decided I was going to work on the foundations of quantum theory. That's what I did my Ph.D on.

I believe that we will see a lot of destruction, but I believe that if we can see the right patterns and draw the right lessons from that destruction, we might be able to rebuild before it's too late. And then I have that ultimate optimism that even if we can't, life will rebuild itself. In a way, the global economy might collapse, but Gaia won't, and people's ingenuity won't. We will rebuild society, we will rebuild local economies, we will rebuild human aspirations.

That amazing power of being able to stand with total courage in the face of total power and not be afraid. That is stri shakti.

In nature's economy the currency is not money, it is life.

Amory Lovins has said that the only reason Americans look efficient is that each has 300 energy slaves. Those 300 energy slaves will now be reproduced among the elite of India.

The primary threat to nature and people today comes from centralising and monopolising power and control. Not until diversity is made the logic of production will there be a chance for sustainability, justice and peace. Cultivating and conserving diversity is no luxury in our times: it is a survival imperative.

The system of technological production that we have today has been justified in terms of creating more goods to feed more people and to meet more needs. But it actually destroys more of the resources that we need in order to meet those multiple needs. If we shift to an ecological perception, a diversity perception, we realize that some of the instruments of which we are very proud are actually extremely primitive for dealing with nature. To me that is the great lesson of ecological awareness at the turn of the millennium.
