More and more I think of privatisation as being not just about the takeover of resources and power by corporate interests, but as the retreat of citizens to private life and private space, screened from solidarity with strangers and increasingly afraid or even unable to imagine acting in public.

To be hopeful means to be uncertain about the future, to be tender toward possibilities, to be dedicated to change all the way down to the bottom of your heart.

What gets called 'the sixties' left a mixed legacy and a lot of divides.

Hope is not a lottery ticket you can sit on the sofa and clutch, feeling lucky. It is an axe you break down doors with in an emergency. Hope should shove you out the door, because it will take everything you have to steer the future away from endless war, from the annihilation of the earth's treasures and the grinding down of the poor and marginal. To hope is to give yourself to the future - and that commitment to the future is what makes the present inhabitable.
