The idea of "human rights," for example - sometimes it bothers me. Not in itself, but because the concept of human rights has replaced the much grander idea of justice.

It's odd how those who dismiss the peace movement as utopian, don't hesitate to proffer the most absurdly dreamy reasons for going to war: to stamp out terrorism, install democracy, eliminate fascism, and most entertainingly, to "rid the world of evil-doers.

Another world is not only possible, she is on her way. On a quiet day, I can hear her breathing.

I think the Occupy movement will, or at least should, become a protean movement of ideas, as well as action, where the element of surprise remains with the protesters. We need to preserve the element of an intellectual ambush and a physical manifestation that takes the government and the police by surprise. It has to keep re-imagining itself, because holding territory may not be something the movement will be allowed to do in a state as powerful and violent as the United States.

The idea of justice - even just dreaming of justice - is revolutionary. The language of human rights tends to accept a status quo that is intrinsically unjust - and then tries to make it more accountable.

From being a dream, dams have become a very cynical corrupt enterprise; a way of letting governments lay their hands on huge sums of money; a way of centralizing resources; a way of snatching rivers away from the poor and giving them to the rich. And so in a sense they've become monuments to corruption.

I actually did a quick survey of how caste plays out in contemporary India. The idea that democracy and development have in some ways eroded caste turned out not to be the case, that it has in fact been entrenched and modernised.
