I want to think about trees. Trees have a curious relationship to the subject of the present moment. There are many created things in the universe that outlive us, that outlive the sun, even, but I can’t think about them. I live with trees. There are creatures under our feet, creatures that live over our heads, but trees live quite convincingly in the same filament of air we inhabit, and in addition, they extend impressively in both directions, up and down, shearing rock and fanning air, doing their real business just out of reach.
