" I have a friend who feels sometimes that the world is hostile to human life--he says it chills us and kills us. But how could we be were it not for this planet that provided our very shape? Two conditions--gravity and a livable temperature range between freezing and boiling--have given us fluids and flesh. The trees we climb and the ground we walk on have given us five fingers and toes. The " place" (from the root plat, broad, spreading, flat) gave us far-seeing eyes, the streams and breezes gave us versatile tongues and whorly ears. The land gave us a stride, and the lake a dive. The amazement gave us our kind of mind. We should be thankful for that, and take nature's stricter lessons with some grace. "
