And yet McPhee’s work is not melancholy, macabre, sad or defeatist. It is full of life. Learning, for him, is a way of loving the world, savoring it, before it’s gone. In the grand cosmology of John McPhee, all the earth’s facts touch one another — all its regions, creatures and eras. Its absences and presences. Fish, trucks, atoms, bears, whiskey, grass, rocks, lacrosse, weird prehistoric oysters, grandchildren and Pangea. Every part of time touches every other part of time. You just have to find the right structure.
