Students told me he was the most extraordinary man they'd ever encountered. He had seemed not quite of this world, they said. He seemed to live in a state of uninterrupted marvel, and he encouraged them to do the same. He didn't so much teach them how to write poetry, they said, but why: because of delight. Because of stubborn gladness. He told them that they must live their most creative lives as a means of fighting back against the ruthless furnace of this world.
