I saw a tree in a forest, and asked him, "Who are you?" He said, "I'm the tallest tree around." I cut off his top -- making him level with the rest -- and asked again, "Who are you?" He said, "A redwood; a mighty Sequoia." So I burned and destroyed his brothers, till the statement "Sequoia" had lost its meaning, and I asked again, "Who are you?" He waited, then said, "A member of the coniferous, cone-bearing family." I destroyed his family, to the last sprouting tree, and asked him again. He said, "I am a tree, with branches reaching to heaven." So I wiped out all other species, until he was completely alone on Earth. And I asked again. He waited longer, then said, "I am a living, growing being." Then all matter I destroyed, until there were no atoms but his atoms, and I asked again, "Who are you now?" I have yet to hear his answer.
