We are either going to have a future where women lead the way to make peace with the Earth or we are not going to have a human future at all.

My mother was a tremendous woman. I was just cleaning up old trunks and I found a book with her notes written during the war years, in the 1940s. She was studying in Lahore, which became Pakistan. She was writing about how women alone could bring peace to the world, that the men with all their greed and egos were creating all these tensions and violence. I always knew she was a feminist, ahead of her time.

My links with [Mahatma] Gandhi now are very political links because I do not believe there is any other politics available to us in the late twentieth century, a period of a totalitarianism linked with the market. There is really no other way you can do politics and create freedom for people without the kinds of instruments he revived. Civil disobedience is a way to create permanent democracy, perennial democracy, a direct democracy.

There is now a patent restricting the use of an herb called philantis neruri for curing jaundice. An even more blatant example is the use of turmeric for healing wounds, which is something every mother and grandmother does in every home in India. Now the Mississippi Medical Center claims to have "invented" the capacity of turmeric to heal wounds.

We have reached a stage where governments and political processes have been hijacked by the corporate world. Corporations can within five hours influence the vote in the U.S. Congress. They can influence the entire voting patterns of the Indian Parliament. Ordinary people who put governments in power might want to go in a different direction. I call this the phenomenon of the inverted state, where the state is no longer accountable to the people. The state only serves the interests of corporations.

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.

My travels through physics really are the same urges that make me travel through ecology. They are not really different, except that there is an added dimension of seeing ecological destruction and seeing the very life-support system that makes us survive on this planet being destroyed. That makes me do more than just inquire; it compels me to act and to intervene.
