What's your story? It's all in the telling. Stories are compasses and architecture; we navigate by them, and to be without a story is to be lost in the vastness of world that spreads in all directions like arctic tundra or sea ice. To love someone is to put yourself in their place, we say, which is to put yourself in their story, or figure out how to tell yourself their story. Which means that a place is a story, and stories are geography, and empathy is first of all an act of imagination, a storyteller's art, and then a way of traveling from here to there.

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.

Perhaps it’s that you can’t go back in time, but you can return to the scenes of a love, of a crime, of happiness, and of a fatal decision; the places are what remain, are what you can possess, are what is immortal. They become the tangible landscape of memory, the places that made you, and in some way you too become them. They are what you can possess and in the end what possesses you.

Sometimes it seems that the fate of the world is decided entirely in the ether of electronic communications and corporate backroom deals.

For me the insurrectionary possibilities of disaster are what make them really interesting and sometimes positive - Mexico City's big 1985 earthquake brought a lot of positive, populist, anti-institutional social change.

You write your books. You scatter your seeds. Rats might eat them, or they might rot. In California, some seeds lie dormant for decades because they only germinate after fire, and sometimes the burned landscape blooms most lavishly.

I roam around a lot in my territory, but what I learn at one end inflects and opens up my understanding at the other.
