This is the last paragraph of the post:
"Our hikes to famous arches like Delicate and Druid have turned us into arch “hounds,” always on the lookout for new ones. We were hiking on the Moab Rim Trail, and Karen spotted an arch along a cliff. We walked over to get a better view. In case it didn’t have a name, we christened it Karen’s Arch. In the distance were the rocky battlements created by the relentless knifing action of the Colorado River. From any vantage point, they look like eternal backdrops in a play that goes on forever. They reminded me of the “metaphysical” art of the Italian painter Georgio de Chirico. He painted urban landscapes that try to make us see the perfect Platonic forms that underlie what we think is reality. But de Chirico’s metaphysic is false. There are no true and eternal forms. There are only appearances, and these are always in flux. Some last a short time, like the artist’s paintings; others, like the rocks, last for millions of years. But all will turn to dust or sand someday. Only the universe itself might go on forever. Still, it gives me comfort to look at the arches, at the rocks around them, at the world we have but only partially created, and dream of those who came here before me and those who will come after."
