Musing takes place in a kind of meadowlands of the imagination, a part of the imagination that has not yet been plowed, developed, or put to any immediately practical use…time spent there is not work time, yet without that time the mind becomes sterile, dull, domesticated. The fight for free space — for wilderness and public space — must be accompanied by a fight for free time to spend wandering in that space.

The present rearranges the past. We never tell the story whole because a life isn't a story; it's a whole Milky Way of events and we are forever picking out constellations from it to fit who and where we are.

Perhaps the central question about [Eliot] Porter's work is about the relationship between science, aesthetics, and environmental politics. His brother, the painter and critic Fairfield Porter, wrote in a 1960 review of [Porter's] colour photographs: 'There is no subject and background, every corner is alive,' and this suggests what an ecological aesthetic might look like.

What is kind of beautiful about Katrina is that even though the media and officials are working hard at telling us everyone in New Orleans was a monster, in the immediate aftermath more than 200,000 people invite displaced strangers into their homes through hurricanehousing.org and an uncounted horde go to New Orleans and the Gulf Coast to give, to love, to be in solidarity, and to rebuild.

Sure, you can say nuclear power is somewhat less carbon-intensive than burning fossil fuels for energy; beating your children to death with a club will prevent them from getting hit by a car. Ravaging the Earth by one irreparable means is not a sensible way to prevent it from being destroyed by another. There are alternatives. We should choose them and use them.

Revolution is a phase, a mood, like spring, and just as spring has its buds and showers, so revolution has its ebullience, its bravery, its hope, and its solidarity. Some of these things pass.
